Acoustic analyses of speech naturalness: a comparison between two therapeutic approaches

acoustic analyses of speech naturalness.

to use voice onset time (VOT) measure as a parameter of speech naturalness, comparing the outcome of two stuttering treatment procedures.

12 adult stutterers were divided in two groups and submitted to the same Fluency Promotion Program (FPF). For GI: surface electromyography (EMG) was used as biofeedback.

the results indicate that for GI 50% of the participants presented a more natural sounding speech after the FPF, whereas for GII only 17% of the participants demonstrated adequate speech naturalness in the same period.

although the number of participants of this research was small, the association of EMG to a FPP seems to produce a more natural sounding speech.
