RHVoice is a Russian speech synthesizer written by Olga Yakovleva.
It uses the following free software components:
* Russian speech database and Russian language description for
 Festival by Nickolay V. Shmyrev (https://developer.berlios.de/projects/festlang)
 The phoneset and almost all of the main lts rules are used as is,
 but I've made changes in other parts, either to simplify conversion
 to the flite format, or to add new features, or just to understand
 how it all works.
* The voice has been trained with The HMM-based Speech Synthesis
 System (HTS) (http://hts.sp.nitech.ac.jp)
* The hts_engine API is used for runtime speech generation
 (http://hts-engine.sourceforge.net/)
 Since the library does not support streaming synthesis, the original
 version has been modified to implement this functionality, and the
 synthesizer distribution includes this patched version.
* The C implementation of the Russian text analyzer uses Flite
 (http://www.speech.cs.cmu.edu/flite)
 I used the flite's implementation of English language support as an
 example, some functions were used as a starting point.
* the stress information for the stress dictionary has been extracted
 from the test dictionary in the RuLex package by Igor B. Poretsky
 (http://poretsky.homelinux.net/packages/)
* GNU libunistring is used for working with unicode text
