Text-To-Speech plugins¶
The Text-To-Speech plugins allow you to connect Open Voice OS with different TTS servers, it could be Piper, Coqui, Amazon Polly, Mimic, etc... Each of these TTS providers will have different voices and languages.
Note
The Text-To-Speech plugins are handled by the ovos_audio container.
The ovos_audio container comes with few pre-installed TTS plugins such as:
ovos-tts-plugin-pollyis the Amazon Polly TTS server (authentication required)ovos-tts-plugin-serverallows you to reach an external TTS service
If the existing TTS plugins are not enough then you can install yours by following the same principle as for the skills by adding an audio.list file within the ~/ovos/config/ directory, this file acts as a Python requirements.txt file.
Plugins requirements
These plugins have to be compatible with the pip install method which requires a setup.py file.
When the ovos_audio container starts, it will look for this file and install the plugins defined in there.
ovos-tts-plugin-marytts==0.0.1a1 # Specific plugin version on PyPi
neon-tts-plugin-mozilla-remote # Latest plugin version on PyPi
git+https://github.com/OpenVoiceOS/ovos-tts-plugin-piper.git@fix/whatever # Specific branch of a plugin on GitHub
The ovos_audio container must be restarted if a change occurs in the audio.list file.
