This integration allows to use Google Cloud Speech-to-Text in Home Assistant.

You can install this integration via HACS. Go to HACS / Integrations / Three-dots menu / Custom repositories and add:

• Repository: https://github.com/chatziko/ha-google-cloud-stt
• Category: Integration

Then install the "Google Cloud Speech-To-Text" integration.

To use it you need to configure a Google Cloud project, following the same instructions as the Google Cloud Text-to-Speach integration. Then place the JSON file with the API key you downloaded in the config folder, and add the following to your configuration.yaml:

stt:
  - platform: google_cloud_stt
    key_file: googlecloud.json
    model: command_and_search

After enabling the integration, you can configure a Voice Assistant to use it by selecting google_cloud_stt in the "Speech-to-text" option.

The supported languages are listed here. Note that V1 of Google Cloud Speech-to-Text is used (it is available in more languages and has a free tier). The list of available models is avaiable here. The default model is command_and_search, since it is available in most languages and should perform well in home automation tasks.

The stt integration does not support any configuration parameters, got [{'platform': 'google_cloud_stt', 'key_file': 'google-cloud-service-googlecloud.json', 'model': 'command_and_search'}]. Please remove the configuration parameters from your configuration.

This is a known issue due to a bug in Home Assistant >= 2023.7. However, the reported message does not affect the functionality of this integration, it should still work as expected (if properly configured).

At the time of writing the pricing of Google Cloud Speech-to-Text V1 is:

• Free for the first 60 minutes / month.
• $0.024 / minute after the first 60 minutes/month.
