METHOD, DEVICE AND COMPUTER PROGRAM CODE MEANS FOR VOICE CONVERSION |
摘要 |
<p>A method of converting a source speakers speech signal into a converted speech signal, which comprises a stage of training using a given database of parallel source and target data. For each pitch period modelling a glottal waveform and a vocal tract filter to obtain a set of parameters comprising an excitation strength, parameters modelling a glottal waveform, and all-pole vocal tract filter coefficients. Defining a glottal vector to be converted; defining a vocal tract vector to be converted, obtaining an estimate of a glottal aspiration noise and estimating a vocal tract transformation function. The stage of modelling comprises: modelling said aspiration noise estimate by- modulating Gaussian noise with the said modelled glottal waveform and adjusting its energy to match that of the said aspiration noise estimate. The method further comprises a stage of conversion and a stage of synthesis.</p> |
