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.

The method of claim 1 , further comprising: stopping speech recognition processing of the recorded acoustic data at a first speech-to-silence transition after the first location.
