Is there a way to have change female to male voice during the conversation in DialogFlow (Api.ai)

Question

We a building a chatbot app for Google Home using Api.ai (Dialogflow now) which has both male and female historical figures. We are using Actions on google. Google lets you

Answer 1

Maybe. Although SSML supports a tag, the documentation for Actions does not list it as supported. However, as you noted, there appears to be some support. The gender and variant attributes seem to work, at least for en-US. The languages attribute doesn't seem to be. So something like this might work:

    male
    male
    female
    female

However what is documented as working is to adjust the pitch of the default voice (whichever one you pick) using the SSML tag. Here is an example you can use to see how it sounds if you vary the pitch:

    test

    test
    test
    test
    test
    test
    test
    test
    test
    test
    test

    test
    test
    test
    test
    test
    test

You can also combine the two tags.
