Effects of auditory feedback on F0 trajectory generation
نویسندگان
چکیده
In this paper, a method is proposed to evaluate contributions of auditory feedback to speech F0 trajectory generation. This method is based on data obtained in a series of new auditory feedback experiments (TAF: transformed auditory feedback) in which quantitative measurements were taken of interactions between speech perception and production under natural speech conditions. Experimental results revealed that the effects on power spectra of F0 trajectories vary among subjects and that the maximum magnitude exceeds 10 dB.

Effects of frequency-shifted auditory feedback on voice F0 contours in syllables.
Previous studies have shown that, during continuous vocalization, voice fundamental frequency (voice F0) is modified by frequency-shifted auditory feedback. In this study, the effects of frequency-shifted auditory feedback on voice F0 contours were determined for the first two syllables of the nonsense word [tatatas]. Results show that voice F0 is auditorily controlled with a long latency and r...
متن کاملPerceptual calibration of F0 production: evidence from feedback perturbation.
Hearing one's own speech is important for language learning and maintenance of accurate articulation. For example, people with postlinguistically acquired deafness often show a gradual deterioration of many aspects of speech production. In this manuscript, data are presented that address the role played by acoustic feedback in the control of voice fundamental frequency (F0). Eighteen subjects p...
متن کاملCompensation for pitch-shifted auditory feedback during the production of Mandarin tone sequences.
Recent research has found that while speaking, subjects react to perturbations in pitch of voice auditory feedback by changing their voice fundamental frequency (F0) to compensate for the perceived pitch-shift. The long response latencies (150-200 ms) suggest they may be too slow to assist in on-line control of the local pitch contour patterns associated with lexical tones on a syllable-to-syll...

Objective: This study was a basic investigation of the ability of concurrent speech segregation in hearing impaired children. Concurrent segregation is one of the fundamental components of auditory scene analysis and plays an important role in speech perception. In the present study, we compared auditory late responses or ALRs between hearing impaired and normal children. Materials & Methods...

The main goal of this study is to determine the auditory feedback effects in improvement of speech production process in prelingual totally deaf children who used cochlear implant prosthesis. For this reason, we recorded speech of four prelingual cochlear implant children pre and post of operation. Then we extract some static features of vowels-such as fundamental frequency, formant frequencies...
