| Abstract | In this paper we present AhoTransf, a tool that enables analysis,visualization, modification and synthesis of speech. AhoTransf integrates aspeech signal analysis model with a graphical user interface to allowvisualization and modification of the parameters of the model. The synthesiscapability allows hearing the modified signal thus providing a quick way tounderstand the perceptual effect of the changes in the parameters of the model.The speech analysis/synthesis algorithm is based in the Multiband Excitationtechnique, but uses a novel phase information representation the Relative PhaseShift (RPS’s). With this representation, not only the amplitudes but also thephases of the harmonic components of the speech signal reveal their structuredpatterns in the visualization tool. AhoTransf is modularly conceived so that itcan be used with different harmonic speech models. |
