Microsoft Text-to-Speech (TTS)

The microsoft text-to-speech platform uses the TTS engine of the Microsoft Speech Service to read a text with natural sounding voices. This integration uses an API that is part of the Cognitive Services offering and is known as the Microsoft Speech API. For this integration to work, you need a free API key. You can use your Azure subscription to create an Azure Speech resource.

Configuration

To enable text-to-speech with Microsoft, add the following lines to your configuration.yaml:

# Example configuration.yaml entry
tts:
  - platform: microsoft
    api_key: YOUR_API_KEY

Configuration Variables

api_key string Required

Your API key.

language string (Optional, default: en-us)

The language to use. Note that if you set the language to anything other than the default, you will need to specify a matching voice type as well. For the supported languages check the list of available languages.

gender string (Optional, default: Female)

The gender you would like to use for the voice. Accepted values are Female and Male.

type string (Optional)

The voice type you want to use. Accepted values are listed as the service name mapping in the documentation.

Default:

JennyNeural

rate integer (Optional, default: 0)

Change the rate of speaking in percentage. Example values: 25, 50.

volume integer (Optional, default: 0)

Change the volume of the output in percentage. Example values: -20, 70.

pitch string (Optional, default: default)

Change the pitch of the output. Example values: high.

contour string (Optional)

Change the contour of the output in percentages. This overrides the pitch setting. See the W3 SSML specification for what it does. Example value: (0,0) (100,100).

region string (Optional, default: eastus)

The region of your API endpoint. See documentation.

Not all Azure regions support high-quality neural voices. Use this overview to determine the availability of standard and neural voices by region/endpoint.

New users (any newly created Azure Speech resource after August 31st, 2021) can only use neural voices. Existing resources can continue using standard voices through August 31st, 2024.

If you set the language to anything other than the default en-us, you will need to specify a matching voice type as well.
