Voice PE without TTS

[rancid skiff]

Is it possible to use Voice PE without TTS?
My PE is only doing simple stuff like turning on lights, hence I don‘t need it to answer with „ok“ or „done“.

Whenever I just disable TTS in my pipeline, Voice PE is not working any. It reacts to the wake word but nothing happens. Even the LED circle is not turning on.

This is what I get in the logs:
There were no events in this run.

if you are calling an automation with a conversation trigger you can set the conversation response to be blank (needs to be at least a char so " " will work)
for for stock local commands theres no easy way to do this i dont think.
you could mute the device but that would stop you hearing anything from it

I believe one could fork voice_assistant component and just omit TTS processing 🙂

So there is no way to just in general disable TTS? This may be a feature request.

if you use a LLM i suppose you might be able to prompt engineer a solution but for local processing i don't think there is a way. to be fair its not the first time i have seen someone ask about this so perhaps slapping in a FR might be the way to go

Pipeline right now consists of wake word, TTS, conversation agent and TTS. It's four pillars - IDK if it's hard to just pull one out. 🙂

You can create a wyoming dummy server that only receives data from HA but does nothing. For example, return an empty file for all requests.

Nothing to do with PE though.

Also if you're experienced with creating your own Wyoming implementation, please share as much as you can. I'm digging into that protocol now.

Based on the already known wyoming-say integration, I managed to create a server for a local (Russian) TTS engine. To be more precise, the work was done by Gemini. Working with chunk processing and other aspects is quite complex for me. If you're interested in taking a look, the result is here. https://github.com/mitrokun/vosk_tts_hass/tree/main/wyoming_vosk. However, you'll need to translate all the comments and descriptions.

I know Russian. But it won't be very helpful - i translate Wyoming to Kotlin.. 🙂
