A speech-directed user interface system includes at least one speaker for delivering an audio signal to a user and at least one microphone for capturing speech utterances of a user. An interface device interfaces with the speaker and microphone and provides a plurality of audio signals to the speaker to be heard by the user. A control circuit is operably coupled with the interface device and is configured for selecting at least one of the plurality of audio signals as a foreground audio signal for delivery to the user through the speaker. The control circuit is operable for recognizing speech utterances of a user and using the recognized speech utterances to control the selection of the foreground audio signal.
