Voice activate your smart assistant with any greeting and start giving your voice instructions.

This voice activator listens for relative changing microphone levels. When the level is changed above an average relative limit, speech recognition is started. The relative microphone base level is thus automatically adjusted for.

Only using the speech recognition block is otherwise a more simple approach that also adapts for noise although it may not be suited for "always on" sound listening. This flow is an attempt to bridge this issue without installing a separate hotword listening app, like the Tasker Hotword plugin. It is unclear which solution is the most energy efficient.
