| Research Abstract |
A new method to accurately estimate the response characteristics of the auditory feedback control of speech has been developed with an open loop system. It covers the latency range from ten to more than several hundred ms after the onset of the modulation of auditory pseudo-feedback signals. The frequency dependence of the feedback gain of the voice fundamental frequency (F0) was observed in the control but not in the stuttering subjects. The feedback characteristics of F0 comprised 3 principal components with different latencies that were modulated differentially depending on attentional conditions.
The first formant (F1) showed either compensating or following responses to F1 steps, while the specific conditions for the difference are to be studied. Functional brain imaging of word reading revealed a difference in the brain activation pattern and its dependence on word familiarity between the people who stutter and who do not, using both fMRI and NIRS (near infrared spectroscopy).
