METHOD AND APPARATUS FOR PROCESSING AN INPUT SPEECH SIGNAL DURING PRESENTATION OF AN OUTPUT AUDIO SIGNAL
First Claim
1. A method for processing an input speech signal during presentation of an output audio signal, the method comprising steps of:
- detecting a start of the input speech signal;
determining, relative to the output audio signal, an input start time of the start of the input speech signal; and
providing the input start time for use in responding to the input speech signal.

Abstract
A start of an input speech signal is detected during presentation of an output audio signal and an input start time, relative to the output audio signal, is determined. The input start time is then provided for use in responding to the input speech signal. In another embodiment, the output audio signal has a corresponding identification. When the input speech signal is detected during presentation of the output audio signal, the identification of the output audio signal is provided for use in responding to the input speech signal. Information signals comprising data and/or control signals are provided in response to at least the contextual information provided, i.e., the input start time and/or the identification of the output audio signal. In this manner, the present invention accurately establishes a context of an input speech signal relative to an output audio signal regardless of the delay characteristics of the underlying communication system.
