Change google assistant voice programmatically

For most languages, the Google Assistant allows developers to choose from 4 type of voice as of now, 2 from female and 2 from male, for most languages.

I want to know the way to change it dynamically through node/java library.

I have tried with actions-on-google-nodejs but did not find anything in it.

I know we can change it either from google assistant application or from deployment setting, but do we have any way to change it dynamically?

Yes. Although not documented (except in StackOverflow currently) you can use the <voice> SSML tag to change which type is used. You can further adjust the pitch to create additional variants.

You can send SSML back using the actions-on-google-nodejs library by either including a string with valid SSML or by explicitly creating a SimpleResponse and setting the ssml property.

The multivocal library includes the ability to pre-define voices as combinations of the voice and prosody tags and will let you easily define which voice is to be used for each response.
