Word to describe action of an audio indicator

Wondering if there is a good word to fit the following:

Indicate is to lamp (or LED, light, globe, display)
or
Prickle is to electrical shock (or wire brush)
or
Buzz is to vibrator
as
_____ is to beeper (or speaker, bell, buzzer)

I read an instruction that mentioned an indicator but they were referring to a speaker and not a light and it felt clumsy.

I am wondering if there is a word like indicator, which has a feeling of visual sense, that would be more appropriate for auditory signalling.

EDIT:
Fixed word form, Added some more senses that may help direct enquiry.

The apparatus will indicate the ready state.

I am hoping that to replace the word indicate with something else in an instruction manual that would let the reader presume the ready state signal is from an audio source rather than a light source. The word sound seems old fashioned and would have matched OK with bells and buzzers of yesteryear that were often collectively referred to as sounders but would not make as much sense in the contemporary world of ear-buds, mini speakers and tiny buzzers and beepers on modern electronics. The word signal seems like a possible alternative to indicate but it does not strongly suggest audio, it could be referring to a flag that pops up so not ideal either.
