33. The system of claim 27 , where the high frequency consonant detector comprises a non-transitory computer-readable medium or circuit.
27. A system that identifies a beginning and an end of a speech segment comprising: an end-pointer comprising a processor that analyzes a dynamic aspect of an audio stream to determine the beginning and the end of the speech segment; and a high frequency consonant detector that marks the end of the speech segment, where the high frequency consonant detector calculates a difference between a signal-to-noise ratio in a high frequency band of the audio stream and a signal-to-noise ratio in a low frequency band of the audio stream, and where the high frequency consonant detector converts the difference between the signal-to-noise ratio in the high frequency band and the signal-to-noise ratio in the low frequency band into a probability value that predicts a likelihood that a high frequency consonant exists in a frame of the audio stream; where the beginning of the speech segment and the end of the speech segment represent boundaries between speech and non-speech portions of the audio stream, and where the end-pointer identifies the beginning of the audio speech segment or the end of the audio speech segment based on an output of the high frequency consonant detector.
