Abstract

The PAOLA algorithm is an efficient algorithm for the timescale modification of speech. It uses a simple peak alignment technique to synchronise synthesis frames and takes waveform properties and the desired time-scale factor into account to determine optimum algorithm parameters. However, PAOLA has difficulties with certain waveform types and can result in poor synchronisation for subband implementations. SOLA is a less efficient algorithm but resolves the issues associated with PAOLA's implementation. We present an algorithm that is a combination of the two approaches that proves to be an efficient and effective algorithm for a subband implementation.
