摘要:A speech signal processor comprising: a modelling block, configured to receivea frequency-domain-input-signal representing of a speech signal, a fundamental-frequency-signal representative of a fundamental frequency of the frequency-domain-input-signal; and configured to provide a pitch-model-signal providing an idealisedspectrum for the original time sampled signalm said pitch-model-signal being based on aperiodic function, the pitch-model-signal spanning a plurality of discrete frequency bins,each discrete frequency bin having a respective discrete frequency bin index, whereinwithin each discrete frequency bin the pitch-model-signal is defined by: the periodicfunction; the fundamental frequency; the frequency-domain-input-signal; and therespective discrete frequency bin index. The speech signal processor further comprises amanipulation block, configured to provide an output-signal based on the frequency-domain-input-signal and the pitch-model-signal.
