Why am I getting this error?

Error on init TTS: Invalid options found: [‘language’]

This is my TTS config:

# Text to speech
tts:
  - platform: google_translate
    service_name: google_translate_say
    base_url: http://192.168.1.58:8123

Is this coming from Cloud TTS?

That is not the configuration used, as the error is about an unsupported (for google) „language“ attribute.

That’s what is confusing me. So where is it coming from?

From the configuration that is actually used, which is not the one you are showing.

Check if the file is really read by HA, maybe change something else and check if it is reflected by HA.

My config is straight from the documentation and works perfectly.

# Example configuration.yaml entry for Google Translate TTS service
tts:
  - platform: google_translate
    cache: true
    cache_dir: /tmp/tts
    time_memory: 300
    base_url: http://192.168.0.10:8123
    service_name: google_say
