Abstract:
1. A method for enhancing speech intelligibility of a speech signal, comprising: performing syllable segmentation on a frame of the speech signal in order to detect a syllable; dynamically determining a scaling factor for a segment of speech in response to performing syllable segmentation on a frame of the speech signal in order to detect a syllable, wherein the segment is contained in the frame; applying the scaling factor to the segment in order to modify a time scaling to the segment; and blending the segment with an overlapping segment in order to essentially retain a frequency attribute of the speech signal that is processed, wherein: the syllable is a time-scale modification syllable (TSMS) comprising a consonant-vowel transition and a steady-state vowel, and dynamically determining a scaling factor for a segment of speech comprises:
