This paper describes a speaking rate adaptation technique for automatic speech recognition. The technique aims to reduce speaking rate variations by applying temporal warping in front-end processing so that the average phone duration in terms of feature frames remains constant. Speaking rate estimates are given by timing information from unadapted decoding outputs. We implement the proposed continuous frame rate normalization (CFRN) technique on a state-of-the-art speech recognition… CONTINUE READING
