Abstract
Embodiments are directed to receiving a speech signal representative of audible speech, processing the speech signal to interpret the speech signal by a dialog system implemented at least partially in hardware, determining, by the dialog system, that the speech signal cannot be correctly interpreted, receiving a noise signal representative of audible background noise, identifying a noise level from the noise signal, determining, by the dialog system, that the noise level is too high for the speech signal to be correctly interpreted, and providing, by the dialog system, a message indicating that the noise level is too high for the speech signal to be correctly interpreted.
