Google TTS problem

Hi guys,
I am a newbie in Hassio.
I have a little problem with my TTS.
In my configuration.yaml I put

  • platform: google_translate
    cache: true
    cache_dir: /tmp/tts
    time_memory: 300
    service_name: google_say
    language: ‘fr’

When I put a message directly in my google home mini via the first page to send a message, my google mini speak the message, but in english! not in french.

In 2nd time when I use the service in developement, I have this message :
Échec d’appel du service “tts/google_say”. expected dict for dictionary value @ data[‘service_data’]. Got [{‘service’: ‘tts.google_say’, ‘entity_id’: ‘media_player.gabin’, ‘data’: {‘message’: ‘Attention, les volets vont se fermer’, ‘language’: ‘fr’}}]

I don’t use SSL/TLS service and don t use duckdns. I use cloud home assistant in hassio.
I put a dmz on my routeur to Hassio to test my config

Sorry for my bad english
Could you help me?
