摘要

, with the aim of improving speaker similarity which is an acknowledged weakness of current HMM-based speech synthesisers. All of the techniques investigated are simple but, as we demonstrate using perceptual tests, can make substantial differences to the quality of the synthetic speech. Contrary to common practice in automatic speech recognition, higher waveform sampling rates can offer enhanced feature extraction and improved speaker similarity for speech synthesis. In addition, a generalized logarithmic transform of F
