RHVoice
RHVoice is an open-source speech synthesizer that employs statistical parametric methods, initially developed for Russian and expanded to include languages like American and Scottish English, and Brazilian Portuguese. It functions across Windows, GNU/Linux, and Android, ensuring smooth integration with existing text-to-speech interfaces. Voices are intelligible and derived from natural recordings, and compatibility extends to tools like NVDA. Comprehensive documentation and active community resources facilitate user interaction and project development.
