Abstract: A speech recognition system receives and analyzes speech input from a user in order to recognize and accept a response from the user. Under certain conditions, information about the response expected from the user may be available. In these situations, the available information about the expected response is used to modify the behavior of the speech recognition system by taking this information into account. The modified behavior of the speech recognition system comprises adjusting the rejection threshold when speech input matches the predetermined expected response.

Abstract: A headset is adapted to be positioned on a head and includes a headband assembly for spanning across the head of a user, an earcup assembly coupled proximate one end of the headband assembly, and a power source assembly coupled proximate the other end of the headband assembly. A flexible stabilizing strap has a first end coupled to the headset proximate the earcup assembly and a second end coupled to the headset terminal proximate the power source assembly. The stabilizing strap is adapted to engage the head of a user to further stabilize the headset on the head.
