The server spawns two threads that are * responsible for further processing. * * The text thread (text_thread) reads commands from the text * buffer. Accesses to this buffer are synchronized by text_mutex. The * text thread calls the flite library to convert the text to * speech. The generated wave forms are stored in the wave buffer (ac, * ac_head, ac_tail, ac_synthpos, time_left). Access to this buffer is * synchronized by wave_mutex. * * The wave thread (wave_thread) takes the wave forms from the wave * buffer and plays them via the flite audio interface. * * The text thread is created when text data first arrives in the text * buffer (in function add_command()). It keeps running until a * "silence command is received. When the text buffer gets empty, the * text thread goes to sleep on the condition variable * "_text_condition". It is woke up by the main process when new data * arrives. * * The wave thread works similarly to the text thread. It is created * in s_flush and sleeps on "wave_condition" when the wave buffer * becomes empty. * * The "silence" command (handled in s_clear()) terminates both * threads. The wave thread is cancelled with pthread_cancel() and the * text thread is told to exit by setting text_thread_cancel to a * true value. Both threads are joined to be sure they have * exited. The state of all buffers is reset. * * The "time_left" variable holds the number of seconds of speech data * in the wave buffer. If this value exeeds a certain threshold * (currently 30s), the text thread will stop synthesizing more speech * and will go to sleep on text_condition. The wave thread signals * to the text thread when the wave buffer shrinks. This mechanism * prevents us from synthesizing useless wave forms we may never have * to play and reduces the memory usage of eflite drastically in * situations where the user requests a long document to be read from * top to bottom. * * The advantage of the disign with the condition variables is that it * is simple to understand and verify. Threads are only created by the * server process, each thread in exactly one place. A silence command * resets everything to a well defined state. The audio device is only * accessed by the wave thread which seems to alleviate some issues * with ALSA. * */ #include #include #include #include #include #include #include /* tmp. for dbg. */ #include #include #ifndef STANDALONE #include #endif #include "flite.h" #include "flite_version.h" #include "synthesizer.h" #include "es.h" static int s_close(synth_t *s);

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS Appendix: How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) 19yy This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) 19yy name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. eflite-0.4.1/ChangeLog0000644000000000000000000001704410554005105013235 0ustar rootroot2007-01-18 Michael P.

Compiling Festival Lite === If you already have FLite compiled and its headers and libraries available, then you can skip this step. Otherwise, download FLite and compile it. You can get it from http://www.speech.cs.cmu.edu. Note that Eflite does not use the generated "flite" binary but instead links against the libraries. As of version 1.3 of flite, there is no support for audio playback via Alsa. There are 3rd party patches against flite 1.2 and 1.3 that add Alsa support: They are available from: http://homepage.hispeed.ch/loehrer/flite_alsa.html eflite uses flite for audio playback, thus you will need those patches if you intend to use eflite with Alsa. === 2. Compiling EFlite === If you have checked EFlite out from cvs, then you will first need to generate the configure script from the configure.in file. Do this by running autoconf. If you downloaded the source from the web, then you can skip this step. Then, run configure. This will create a Makefile. It will try to guess at the location of your FLite libraries. If it guesses incorrectly or does not succeed at finding them, then you will need to specify the directory with a command similar to the following: ./configure flite_dir=/usr/src/flite-1.1-release To select the type of audio playback, specify either --with-audio=oss or --with-audio=alsa as options to configure. Once a Makefile has been created, run make. Assuming all goes well, you should get a binary called eflite. You may then run "make install" to install the binary. === 3. Configuring EFlite This step is optional. When EFlite starts, it looks for a configuration file called .es.conf in the user's home directory. If it does not find one there, it looks for a configuration file named /etc/es.conf. Lines in the configuration file are of the form key=value ie: sockname=/tmp/es.socket The following options may be specified in the configuration file: sockname: Specifies the name of the socket that EFlite clients use to communicate with their server. When EFlite is run, it first tries to connect to this socket. If this succeeds, then it will read input from the file passed to it on the command line, or standard input if '-' is specified or if EFlite is run without arguments. Upon failing to connect to the specified socket, EFlite will fork, and the forked process will act as a server, accepting connections on the socket. punct_some: List of punctuation characters to be spoken when the punctuation mode is set to "some.". Default is @#$%^&_[]{}\| punct_all: List of punctuation characters to be spoken when the punctuation mode is set to "all." Default is !@#$%^&*()-=_+[]\|{};':",./<>? speech_volume: Volume of speech unless overridden by a client. Default is 1000. tone_volume: Volume of generated tones (0-32767). Default is 8192. speaker_tones: Allow tones from the PC speaker, if supported. 1 enables; 0 disables. Currently, this option is only meaningful under Linux and when running as root (regardless of whether we have right access to /dev/console). Default is 1. soundcard_tones: Allow tones from the sound card, if supported. 1 enables; 0 disables. Default is 1. These tones may be generated either by writing directly to /dev/dsp (under Linux) or by using FLite's interface (if EFLITE is defined when compiling tone.c, which it is by default). Therefore, the Linux native support is no longer necessary for EFlite's operation and is kept around only to retain the possibility of de-coupling the Emacspeak server core (es.c and helpers) from the Festival Lite support code (fs.c). === 4. Testing EFlite === Once you have compiled EFlite, I would suggest running "make test". This will run EFlite, passing it a test file as input. You should hear a message being spoken. === 5. Configuring your screen reader === [I will discuss Emacspeak and Yasr in this section. If anyone gets Eflite to work with BRASS or anything else and would like to contribute a section for it, then send me some email.] === 5.1. Emacspeak: - Set DTK_PROGRAM to the location of your EFlite binary. If you use /usr/bin/emacspeak, then it may be easiest to place a line similar to the following into emacspeak.conf: export DTK_PROGRAM=/usr/local/bin/eflite Alternatively, the following shell script should get Emacspeak running with EFlite, although you may need to edit some path names: #!/bin/sh export EMACS_UNIBYTE=1 export DTK_PROGRAM=/usr/local/bin/eflite emacs -q -l /usr/share/emacs/site-lisp/emacspeak/lisp/emacspeak-setup.el # You may want to add "-l $HOME/.emacs" to the previous line === 5.2. Yasr === in ~/.yasr.conf (or /etc/yasr.conf), set the value of "Synthesizer" to "Emacspeak server," and set "Synthesizer Port" to the location of your Eflite binary, preceeded by a |. Ie: Synthesizer=Emacspeak server Synthesizer port=|/usr/local/bin/eflite ======================================================================== If there is anything that I haven't covered (and I'm sure that there is), then let me know. -Michael P.

First and foremost, I must thank Kevin Lenzo, Alan Black, and anyone else who has been involved with the Festival and Festival Lite projects. Without all of their hard work in creating a robust text-to-speech synthesizer. Without FLite, EFlite could not exist. The alsa support and accompanying thread cleanups were done by Lukas Loehrer. Several changes were made by Jeremy Huddleston, who also ported eflite to gentoo. There are probably others who I am leaving out, so please let me know if you think I should have included you. =-MPG eflite-0.4.1/README0000644000000000000000000000432210554005105012336 0ustar rootrootREADME for FLite Emacspeak server v0.2.0; 03/03/02 ======================================================================== This code allows Emacspeak, as well as yasr and potentially Brass, to interface with the Festival Lite speech synthesizer. It is currently in the beta stage and not necessarily well polished (well, neither is its documentation, for that matter), but it is working for me, although I have done most of my testing with yasr. See the file INSTALL for instructions on compiling eflite and getting it to work with screen readers. Eflite uses the audio library included with Festival Lite, so it theoretically inherits ALSA support, although I seem to remember having trouble getting the ALSA code to compile (it seems that the ALSA API differs depending on which version is being used). The source is divided into two parts: a generic parser (es.c and some helper files) and a file for interfacing with Festival Lite (fs.c). The interface used by fs.c is borrowed from Roger Butenuth's speech library used by BRASS (in fact, I used his ViaVoice module as a starting point to write fs.c). However, fs.c can be built to link against es.c directly if STANDALONE is defined (this is done in the Makefile). There may be legal issues that would arise if fs.c were linked against libspeech.a from BRASS, since BRASS is GPLed whereas FLite is not, but I am not sure one way or the other. Eflite takes the following options: -D: Run as a daemon and exit; do not read from stdin -d: enable debugging message -fi : read input from -c : Attach to eflite server for the given context (create it if it does not exist yet) -v: print version and exit The "-c" option can be useful when testing new versions of eflite. You do not want to lose speech with your "good" version while performing the test. You would start your test version like this: ./eflite -c test If the test version crashes, your old working version will not be affected. You may also use this option to for example run emacspeak and yasr in different contexts. Send flames, bug reports, etc. to mgorse@alum.wpi.edu. You can also catch me on #blinux on openprojects, as "vortex" -Michael P.
