Cepstral-based estimation is used to provide a baseline estimate of the noise level in the logarithmic spectrum for voiced speech. A theoretical description of cepstral processing of voiced speech containing aspiration noise, together with supporting empirical data, is provided in order to illustrate the nature of the noise baseline estimation process.… (More)
The EXPLAN model is implemented on a graphic simulator. It is shown that it is able to produce speech in serial order and several types of fluency failure produced by fluent speakers and speakers who stutter. A way that EXPLAN accounts for longitudinal changes in the pattern of fluency failures shown by speakers who stutter is demonstrated.
