Masking Noise

The effect of masking noise on the disfluency frequency of 20 adult nonstutterers was investigated. The majority of the subjects became more fluent under this condition. This suggests that an increase in fluency when speaking in the presence of masking noise does not differentiate stutterers from normal speakers.

Masking Noise

Auditory masking was determined for cod by using five half-octave bands as masking stimuli and as signals. For each of 15 cod, masking noise was kept constant at 10 db re 1 microbar in one band while thresholds were determined for signals in all five bands. Results indicate masking to be most pronounced when noise and signal coincide in frequency, and to drop off as frequency separation between noise and signal increases. Masking is calculated in terms of threshold in relation to masking noise level, and varies from about 11 db when signal and noise are in the same band to about −19 db when they are in bands furthest removed from each other. Estimates of critical bands are made from the results.

Masking Noise

6 adult subjects (3 men, 3 women) produced highly similar spontaneous speech utterances in quiet and with 90-dB SPL white noise. The frequency of occurrence of perceptual judgments of primary stressing in an utterance was not affected by the masking noise. This finding supplements our previous report that variability for stress production of fundamental frequency (fo) during spontaneous speech was preserved under short-term auditory disruption. Also, it adds further support to the contention that fo is under open-loop regulation.

Lip Movement

This study describes the effects of unpredictably presented masking noise on selected parameters of lip movement during speech. Four normal subjects produced a simple speech utterance while vertical displacements of the upper and lower lips were transduced and recorded. During selected productions a masking noise was presented dichotically at one of two distinct phases of lip movement. Analysis of the resulting data revealed the following for all subjects: (1) significant changes in the duration, displacement, and velocity of lip movement caused by masking and (2) significant reductions in the velocity of lip movement occurring approximately 50 msec after the onset of the masker. Possible explanations of these and certain speaker-dependent effects are discussed.
