Introduction

Text-to-speech (TTS) is a useful feature in home automation, allowing systems to generate spoken announcements and notifications. OpenTTS is an open-source service supporting multiple speech synthesis backends, including Google TTS, Microsoft Azure, and Piper.

The ha_opentts_integration is a Home Assistant custom integration that enables OpenTTS support. This approach is based on a legacy technique, and it is unclear whether similar implementations exist.

This integration builds on the work of OpenTTS by Synesthesiam, which provides a flexible TTS solution supporting multiple backends. OpenTTS serves as the foundation for this implementation, making it possible to use various speech synthesis engines within Home Assistant.

Why OpenTTS?

OpenTTS provides multiple speech synthesis backends and can be used locally or with cloud-based services. It allows for flexibility in choosing TTS voices while maintaining control over privacy settings.

Features of ha_opentts_integration

This integration:

  • Enables OpenTTS support in Home Assistant
  • Allows configuration of language, voice, and speed settings
  • Works with different TTS engines through OpenTTS
  • Supports media players for spoken notifications
  • Requires minimal configuration

How to Install

To set it up:

  1. Download the Integration
    Clone or download the repository from GitHub:

    git clone https://github.com/RoyOltmans/ha_opentts_integration

  2. Place the Integration in Home Assistant
    Move the ha_opentts_integration folder into the custom_components directory.

  3. Restart Home Assistant
    Reload Home Assistant for the integration to be recognized.

  4. Configure OpenTTS
    Add the following lines to configuration.yaml:

    tts:
  - platform: opentts
    url: "http://your-opentts-server:5500"

    Replace your-opentts-server with the correct IP or hostname.

  5. Test the Integration
    Execute a simple script to check OpenTTS output:

    service: tts.opentts_say
data:
  entity_id: media_player.living_room_speaker
  message: "This is OpenTTS in Home Assistant."

Considerations

This integration relies on a legacy technique, and its long-term viability is uncertain. It is unknown if similar solutions exist or if this is the first implementation of its kind.
