macOS Text-to-Speech

Overview

The macOS Text-to-Speech (TTS) service uses the macOS "say" command for producing spoken text.

Obviously, this service only works on a host that is running macOS.

Configuration

There is no need to configure anything for this service.

Voices

It automatically scans all available voices and registers them, see e.g.

Default Text-to-Speech and Voice Configuration

You can setup your preferred default Text-to-Speech and default voice in the UI:

• Go to Settings.
• Edit System Services - Voice.
• Set macOS TTS as Default Text-to-Speech.
• Choose your preferred Default Voice for your setup.

In case you would like to setup these settings via a text file, you can edit the file runtime.cfg in $OPENHAB_ROOT/conf/services and set the following entries:

org.openhab.voice:defaultTTS=mactts
org.openhab.voice:defaultVoice=mactts:Alex

Supported Audio Formats

The MacTTS service produces audio streams using WAV containers and PCM (signed) codec with 16bit depth and 44.1kHz frequency.
