Decision brief

RHVoice is an open-source text-to-speech system developed for Russian and multiple other languages employing statistical parametric synthesis.

Good fit when

  • - When you need support for less commonly supported languages such as Kyrgyz, Tatar, or Albanian.
  • - If your application requires high intelligibility within a small memory footprint on platforms like Windows, GNU/Linux, and Android.

Avoid when

  • - Avoid if seeking support exclusively for widely used languages like Spanish or Mandarin, where other options may offer more resources and community support.
  • - Not ideal in scenarios where the naturalness of speech synthesis is critical over intelligibility and memory efficiency.

RHVoice

RHVoice is a free and open-source speech synthesizer.

Features

Speech synthesis method

RHVoice uses statistical parametric synthesis. It relies on existing open-source speech technologies (mainly HTS and related software).

Voices are built from recordings of natural speech. They have small footprints, because only statistical models are stored on users' computers. And though the voices lack the naturalness of the synthesizers which generate speech by combining segments of the recordings themselves, they are still very intelligible and resemble the speakers who recorded the source material.

Supported languages

Initially, RHVoice could speak only Russian. Now it also supports:

  • American and Scottish English
  • Brazilian Portuguese
  • Esperanto
  • Georgian
  • Ukrainian
  • Kyrgyz
  • Tatar
  • Macedonian
  • Albanian
  • Polish

In theory, it is possible to implement support for other languages, if all the necessary resources can be found or created.

Synthesis example

If you want to listen to an example of speech synthesis, You can use the TTS service on this page.

Supported platforms

RHVoice supports the following platforms:

  • Windows (prebuilt binaries is available in documentation)
  • GNU/Linux (building instructions and packaging status can be found in "Compiling instructions" section of documentation.
  • Android (can be installed thru F-Droid or Google Play

It is compatible with standard text-to-speech interfaces on these platforms: SAPI5 on Windows, Speech Dispatcher on GNU/Linux and Android's text-to-speech APIs. It can also be used by the NVDA screen reader directly (the driver is provided by RHVoice itself).

Documentation

All prebuild binaries packages, main and legal information and more are available in three languages:

  • English
  • Русский
  • Українська
