Acoustic parameters of voice individuality and voice-quality control by analysis-synthesis method

Abstract Experiments on voice individuality have been performed using an analysis-synthesis system capable of modifying pitch, formant frequencies and formant bandwidths. The results show that the perception of voice-individuality is significantly affected by formant shifts, especially of the lower three, and it is completely lost for a uniform shift of five percent. Pitch frequency and bandwidth manipulation, on the other hand, is less important to the individuality perception.
