Using French language for TTS



I’m not sure if I missed something but can we change the language of the native TTS engine in the platform?
Basically my bot is in French, Google ASR works perfectly for French and my intents are recognized (that’s really amazing) but I would like to make my assistant reply in French. How can I play messages in french? Can I have it using native French TTS engine? If there is no French for native TTS engine can I easily invoke a 3rd party TTS engine (and do you have recommendations)?

Thanks !
