Release an open speech synthesis system Rhvoice 1.6.0 , originally developed to ensure high-quality support for the Russian language, but then adapted for other languages, including English, Portuguese, Ukrainian, Kyrgyz, Tatar and Georgian. The code is written in C ++ and extends under the LGPL 2.1 license. Supported by work in gnu / linux , Windows and android . The program is compatible with typical TTS interfaces (text-to-speed) to convert text to speech: SAPI5 (Windows), Speech Dispatcher ( GNU / Linux) and Android Text-to-Speech API, but can also be used in the on-screen reader NVDA .
Added in the new version 5 new variants of votes for Russian speech. The support of the Albanian language has been implemented. Updated dictionary for the Ukrainian language. The error crashes in the Application for the Android platform, and also added support for the Android platform 11. New settings and functionality are added to the engine core, including G2P.Case, Word_Break and support for filters of equivalent.
Recall that in Rhvoice used projects of the project HTS (HMM / DNN-Based Sight Synthesis System) and parametric method Synthesis with statistical models ( Statistical Parametric Synthesis On the basis of HMM – Hidden Markov Model). The advantage of the statistical model are low overhead and inconspicing capacity to CPU power. All operations are executed locally on the user system. Three levels of speech quality are supported (the lower quality – the higher the performance and less reaction time).
The minus of the statistical model is the relatively low quality of pronunciation, which does not reach the level of synthesizers generating speech based on a combination of natural speech fragments, but nevertheless the result is completely parallending and reminding the broadcast of recording from the loudspeaker. For comparison, the Silero project, providing Open engine for speech synthesis based on machine learning technologies and a set of models for the Russian language, quality Superior Rhvoice.
