We present an improved algorithm for a robust speech analysissynthesis method based on an auto-regressive with exogenous input (ARX) speech production model proposed previously. The speech analysis-synthesis method is capable of making an automatic estimation of vocal tract (formant) and voice source parameters from a speech utterance, generating accurate formant values even for very high-pitch...

Vocal tract morphology is an important factor in voice production. Its analysis has potential implications for educational matters as well as medical issues like voice therapy. The knowledge of the complex adjustments in the spatial geometry of the vocal tract during phonation is still limited. For a major part, this is due to difficulties in acquiring geometry data of the vocal tract in the pr...

These diseases are characterized by obstruction to airflow that interferes with normal breathing and they frequently co-exist. COPD can affect voice as respiration is a vital subsystem for voice production COPD that have a significant voice impairment which...

We present an experiment where voice quality of French and Italian dysphonic speakers was evaluated by French and Italian listeners, specialists in phoniatrics. Results showed that both groups of speakers were perceived in the same way by the two groups of listeners in term of overall severity and breathiness. But the perception of roughness is clearly language dependant. Italian listeners unde...

Automatic Speaker Recognition (ASR) is use to recognizing persons from their voice. Since the voice of every human is not same because their vocal tract shapes, larynx sizes and other parts of a human voice production system. Automatic Speaker recognition is a procedure to automatically recognizing a speaker or who is speaking by the individual information counted in speech signal/waves. Automa...

It has been argued that the use of inverse voice in languages with pragmatic inversion depends on the discourse status of the referents: this voice occurs when the patient outranks the agent in topicality. In our article, we present empirical evidence from Teribe, a Chibchan language of Panama and Costa Rica and we examine the interaction between inverse voice and information structure. We repo...

Ten subjects with adductor spasmodic dysphonia participated in a study examining the effects of an acupuncture treatment protocol on their voice disorder. Treatment consisted of eight sessions, and it was designed and performed by two physicians certified in acupuncture. Voice characteristics were evaluated pretreatment and posttreatment using the CSL Motor Speech Profile (MSP), Unified Spasmod...
