Advanced TTS Plugin Documentation

Several TTS engines have different configuration settings for optimizing its use. Several have different voices to use, or you can specify a TTS server to use.

We will cover basic configuration of the default TTS engine ovos-tts-server-plugin.

All changes will be made in the User configuration file, eg. ~/.config/mycroft/mycroft.conf.

Open the file for editing. nano ~/.config/mycroft/mycroft.conf.

If your file is empty, or does not have a "tts" section, you need to create it. Add this to your config

    "tts": {
        "module": "ovos-tts-server-plugin",
        "fallback_module": "ovos-tts-plugin-piper",
        "ovos-tts-server-plugin": {
            "host": "",
            "voice": "alan-low"
        "ovos-tts-plugin-piper": {}

Sections explained

"module" - This is where you specify what TTS plugin to use. - ovos-tts-server-plugin in this example. - This plugin, by default, uses a random selection of public TTS servers provided by the OVOS community. With no "host" provided, one of those will be used. - You can still change your voice without changing the "host". The default voice is "alan-low", or the Mycroft original voice `"Alan Pope".

Changing your assistant's voice

"fallback_module" - If by chance your first TTS engine fails, OVOS will try to use this one. It is usually configured to use an on device engine so that you always have some output even if you are disconnected from the internet.


"ovos-tts-plugin-piper" - Specify specific plugin settings here. Multiple entries are allowed. If an empty dict is provided, {}, the plugin will use its default values.

Refer to the TTS github repository for specifications on each plugin
