A speech processing system enhances the intelligibility of input speech by selecting at least two frequency bands (eg. one for unvoiced consonants and another for voiced consonants and vowels), applying a different weighting to each to produce a spectrally shaped signal, and temporally scaling/stretching the shaped signal. The scaling may be based on environmental reverberation time and may insert pauses, and the stretched signal may be normalised to have the same Root Mean Square energy as the original signal. |
