Documentation is given in the FSF format which can generate, a printed manual, info files and HTML.įestival is free software. The system is written in C++ and uses the Edinburgh Speech Tools Library for low level architecture and has a Scheme (SIOD) based command interpreter for control. And full tools and documentation for build new voices are available through Carnegie Mellon's FestVox project () Other groups release new languages for the system. Festival is multi-lingual (currently English (British and American), and Spanish) though English is the most advanced. As a whole it offers full text to speech through a number APIs: from shell level, though a Scheme command interpreter, as a C++ library and an Emacs interface. Festival - Speech Synthesis Systemįestival offers a general framework for building speech synthesis systems as well as including examples of various modules. Automatically generate VoiceXML documents using the StringTemplate template engine. SpeakRight is a Java framework for writing speech recognition applications based on VoiceXML technology. Speak Right Framework - Helps to build Speech Recognition Applications MaryTTS comes with tool kits for quickly adding support for new languages and for building unit selection and HMM-based synthesis voices. It is now maintained by the Multimodal Speech Processing Group in the Cluster of Excellence MMCI and DFKI.Īs of version 5.2, MaryTTS supports German, British and American English, French, Italian, Luxembourgish, Russian, Swedish, Telugu, and Turkish more languages are in preparation. It was originally developed as a collaborative project of DFKI ’ s Language Technology Lab and the Institute of Phonetics at Saarland University. M aryTTS is an open-source, multilingual Text-to-Speech Synthesis platform written in Java. T his paper mainly introduces 7 open source TTS systems. TTS is often used with voice recognition programs. TTS can help visually impaired people read information on their computers or simply to increase the readability of text documents. TTS (Text To Speech, text to speech) is a kind of speech synthesis application, which converts files stored in a computer, such as help files or web pages into natural speech output. In Europe and the United States, we have begun to formulate standard implementation standards and implement rules and regulations. Feel free to use with attribution.The application of TTS in TV products can help the blind and amblyopic people who can not use visual standards to access the TV interface. I did not run into the Linux/java sound bug that I found mentioned on StackOverflow while trying to get this to work, but the newest version of FreeTTS is more than a year younger than those issues so I figure it was fixed. Kevin.speak( "You may be wondering why I have gathered you here tonight." ) Īnd you should get glorious machine-generated sound pouring from your speakers. Presumably you can set other voices, which you could probably find by decompiling the cmu_us_kal jar that was in lib, but the Kevin voice is not bad.įinally, you can speak a sentence with the following: Voice kevin = VoiceManager. setProperty( "freetts.voices", ".en.us.cmu_us_kal.KevinVoiceDirectory" ) You'll need to import .*, then set a system property with System. Since I'm an Eclipse user, I then added this to the build path for a project (right click -> properties -> Java Build Path -> libraries tab -> add external jars) and created a new class. Move it into /lib so it's with it's friends. Now jsapi is in whatever directory your shell is in. When you get to the license agreement yes should spam in a y before you hit enter and the script will extract it's payload. Then run yes | /lib/jsapi.sh and page through with enter. However, Linux has a very handy program called yes that will spam y for you.įirst run chmod +x /lib/jsapi.sh to make it an executable script. For some reason, this is buried in what is probably the most annoying license file known to man, which you have to page through with less, but if you hit enter at the end instead of y (because you weren't reading it, of course) you get kicked out and have to start over. Now the first thing you need to do is rip out the jsapi.jar file. Extract the FreeTTS folder out somewhere (I did it to ~/Downloads/freetts). This will get you a zip that looks like a jar but isn't. The first thing you'll want to do is download FreeTTS from it's site. Installing and using FreeTTS in Java on LinuxįreeTTS is a quite handy text-to-speech synthesizer that works in Java.
