RHVoice/RHVoice

a free and open source speech synthesizer for Russian and other languages

What it solves

RHVoice provides a free, open-source alternative for text-to-speech (TTS) synthesis, allowing computers and mobile devices to convert text into spoken audio across multiple languages.

How it works

It uses statistical parametric synthesis based on HMM-based synthesis (specifically relying on HTS and related software). Instead of storing large audio recordings, it stores small statistical models of natural speech, which are then used to generate intelligible speech that resembles the original speakers.

Who it’s for

It is designed for users on Windows, GNU/Linux, and Android who need a lightweight, open-source speech synthesizer, including users of the NVDA screen reader.

Highlights

  • Multi-language support: Supports a wide range of languages including English (American and Scottish), Russian, Brazilian Portuguese, Esperanto, Georgian, Ukrainian, Kyrgyz, Tatar, Macedonian, Albanian, and Polish.
  • ** kinematics Lightweight footprint**: Only statistical models are stored, making it efficient for storage.
  • Platform compatibility: Integrates with SAPI5 (Windows), Speech Dispatcher (Linux), and Android TTS APIs.
  • Screen reader integration: Provides a direct driver for the NVDA screen reader.

    VOICEVOX/voicevox_engine

    VOICEVOX Engine is an open‑source HTTP server that wraps the VOICEVOX Japanese TTS core. It lets you send text (or a detailed synthesis query) via REST endpoints and receive WAV audio, with support for streaming, user dictionaries, presets, voice morphing, singing synthesis, and optional GPU acceleration. Docker images and a mock mode make deployment easy, and the API is documented at /docs.
