Voice Chapter 7 - Supercharged wake words and timers

I head this is possible on the esp32

Can it be possible to only run the wake word, without the rest of the Voice Assistant part? To create a micro voice assistant.

For example, with wake words, microft light, micro music, microft off. In can have a voice assistant with all the commands for that room. And i do not need the rest of the processing power. And i hope that it can been more accurate, for just the 3 commands.

Is it possible to create these wake words?
