change to boolean ENABLE_VOICE_SEARCH for clarity? We only use it as a boolean check anyway. I'd suggest changing the description to:

# This variable controls whether the voice search endpoint is active (set to true) or inactive (set to false). Default is false.

# If enabled, we default to using external services unless `CUSTOM_SPEECH_ENDPOINT` is set, in which case the custom hosted APIs will be used.

Thanks for this - exactly what was needed. Just a comment on what the variable should be called and that it should be a boolean for clarity. Also update the docs with this new info, thanks!

What is TOGGLE_VOICE, I don't see anywhere else. Probably that's what turned into ENABLE_VOICE_SEARCH

You should probably change that in the docs. I saw it in docs/components/voice-service/inded.md

Hello Mustafa, I approved, just a minor change to make.
