SSML Actions on Google, change speaking language

Question

I can't seem to change the language during the conversation. I tried:

<speak>
<voice gender="male" variant="3" langaugeCode="fr">
<prosody rate="105%">
Bonjour
</prosody>
</voice>
</speak>

Any ideas how to do that?

Answer 1

The <voice> tag is not officially supported in the SSML for the Google Assistant, although it does appear to partially work.

Although the gender and variant attributes do appear to work, the SSML spec does not define a languageCode attribute (which you ask about in your question), and the languages attribute does not appear to be supported.
