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 uniform shift of a five percent. Pitch frequency and bandwidth manipulation, on the other hand, is less important to the individuality perception.
