5. The method of claim 1 , wherein the act of recording acoustic data in the at least one recording medium comprises: analyzing a portion of acoustic data recorded in the at least one recording medium to detect at least one silence-to-speech transition or at least one speech-to-silence transition in the portion of acoustic data recorded in the at least one recording medium; and storing an indication of a location of the detected at least one silence-to-speech transition or at least one speech-to-silence transition.
1. A method for processing acoustic data in accordance with a speech recognition system, the method comprising acts of: recording acoustic data in at least one recording medium; detecting, at a first time, an indication to start speech recognition processing, the first time corresponding to a first location of the recorded acoustic data recorded in the at least one recording medium; determining whether the acoustic data recorded at the first time at which the indication to start speech recognition processing was detected is likely to be in a silence region or a speech region; if it is determined that the acoustic data recorded at the first time is likely to be in a speech region, analyzing at least some of the recorded acoustic data before the first location to determine a starting location for speech recognition processing; and if it is determined that the acoustic data recorded at the first time is likely to be in a silence region, analyzing the recorded acoustic data only after the first location to determine a starting location for speech recognition processing.
