sound recognition

Go to Settings > Accessibility > Sound Recognition, then turn on Sound Recognition. Tap Sounds, then turn on the sounds you want your iPhone to recognize.

Recognize sounds using iPhone - Apple Support (IN)

When I turned on sound recognition for fire and smoke, my turn by turn voice audio stopped working in the Maps app. Seems you can’t have sound recognition on and still get audio directions while using maps. Why can’t they both be on and work? Using iOS 15.2 on an SE 2020. Poor software integration??
