This paper describes a pilot study into the mechanics of synthesizing severely pathological voices. Successful synthesis of such voices may ultimately provide a quantitative method for evaluating and documenting voice qualities. An analysis-by-synthesis approach using the formant synthesizer KLSYN was used to model the voices of 24 patients suffering from voice disorders. Results suggest a number of modifications to KLSYN that would facilitate synthesis of these voices.
This paper refers to twenty-three pairs of voices, listed below. The voices were originally sampled at 16-bit and 20kHz, but for the purposes of this page, they were downsampled to 8kHz and compressed into 8-bit mu-law format. Thus, these are not exactly the voices used in the study.
