A Study of Rate Discrimination of Time-Compressed Speech
نویسنده
چکیده
The purpose of this study is to determine the just noticeable differences (JNDs) for speech rate. The results are intended to be used for the design of an interactive speech speed control. The JND at three different speech rates was determined using the psychophysical method of constant stimuli. Speech stimuli were compressed using the SOLA time-compression technique. The findings show a significant increase in the JND as speech rate increases. However, a non-linear increase was found rather than a linear one as predicted by Weber's law. In addition, JNDs were much smaller than initially expected. The results indicate the need for a fine granularity, possibly non-linear, speech speed control.

Objectives: Most of the studies performed on aging and auditory system have historically focused on speech perception disorders in elderly people. According to studies, speech discrimination disorders in aged people usually result from auditory temporal processing impairment. Our study was done to determine the ability of aged people to discriminate time compressed speech. Methods & Material...

Background: The main result of hearing impairment is reduction of speech perception. Patient with auditory neuropathy can hear but they can not understand. Their difficulties have been traced to timing related deficits, revealing the importance of the neural encoding of timing cues for understanding speech. Objective: In the present study psychoacoustic perception (minimal noticeable differen...
متن کاملRecognition of time-compressed speech does not predict recognition of natural fast-rate speech by older listeners.
This study investigated whether recognition of time-compressed speech predicts recognition of natural fast-rate speech, and whether this relationship is influenced by listener age. High and low context sentences were presented to younger and older normal-hearing adults at a normal speech rate, naturally fast speech rate, and fast rate implemented by time compressing the normal-rate sentences. R...
متن کاملWord perception in fast speech: artificially time-compressed vs. naturally produced fast speech
Natural fast speech differs from normal-rate speech with respect to its temporal pattern. Previous results showed that word intelligibility of heavily artificially time-compressed speech could not be improved by making its temporal pattern more similar to that of natural fast speech. This might have been due to the extrapolation of timing rules for natural fast speech to rates that are much fas...
متن کاملDiscrimination of time series based on kernel method
Classical methods in discrimination such as linear and quadratic do not have good efficiency in the case of nongaussian or nonlinear time series data. In nonparametric kernel discrimination in which the kernel estimators of likelihood functions are used instead of their real values has been shown to have good performance. The misclassification rate of kernel discrimination is usually less than ...
