TTS.google_translate_say

I have TTS.google_translate_say working fine with my google home speaker when message is in english, but if I try to use it with a different language it doesn't produce any sound in my speaker.
I have the following syntax for my node:
{"domain":"tts","service":"google_translate_say","data":{"message":"Thank you for closing the front door","language":"es-US","entity_id":"media_player.kitchen_speaker"}}

If I remove the language line, the speaker delivers the message.

Any help is appreciate. TKS
