Acoustic Characteristics Analysis on the Tracheoesophageal Speech

Gang Lv

Abstract


Tracheoesophageal (TE) speech has been the current preferred treatment for speech rehabilitation after total laryngectomy, but due to the lack of objective evaluation criteria, it is tough to operate a qualitative analysis on the effects of postoperative speech rehabilitation. The present paper advanced an objective evaluation system involving acoustic characteristics parameters such as fundamental frequency, formants, jitter, shimmer, harmonics to noise ratio(HNR), the maximum phonation time(MPT), sound intensity and so on. The result showed that compared to subjective evaluation system, the application of objective evaluation system evaluated the effects of speech rehabilitation after total laryngectomy more objectively and precisely.
