Claim:
1. A system comprising: a detector having a housing that carries an ambient condition sensor; an audio output device carried by the housing that generates audio in response to a predetermined condition; an audio input transducer carried by the housing that receives speech audio from a user; control circuits carried by the housing and coupled to the ambient condition sensor, wherein the control circuits include signal processing circuits coupled to the audio input transducer, and wherein the signal processing circuits output a processed speech signal based on the speech audio; and speech recognition circuitry that receives the processed speech signal and recognizes selected speech to implement predetermined functions, wherein, responsive to the processed speech signal indicating a request to silence the audio output device, the control circuits silence the audio output device for a first predetermined time period or a second predetermined time period, wherein the predetermined condition is an alarm condition detected by the ambient condition sensor or a low battery condition detected by the control circuits, wherein the control circuits silence the audio output device for the first predetermined time period responsive to the request to silence the audio output device when the ambient condition sensor detects the alarm condition, wherein the control circuits silence the audio output device for the second predetermined time period responsive to the request to silence the audio output device when the control circuits detect the low battery condition, and wherein the first predetermined time period is shorter than the second predetermined time period.
