Studies on fast speech have shown that word-level timing of fast speech differs from that of normal rate speech in that unstressed syllables are shortened more than stressed syllables as speech rate increases. An earlier experiment showed that the intelligibility of time-compressed speech could not be improved by making its temporal organisation closer to natural fast speech. To test the hypoth...

It is well known that, all things being equal, the accuracy of mammalian timing and memory decays gradually with the passage of time. The gradual decay of temporal accuracy is also observed in single-unit neural recordings. Here we review recent modeling work describing a specific mechanism for timing and memory and relevant neural data. The model describes a neural mechanism that can give rise...

The periodic sampling method of time compression is characterized by periodic removal of segments of speech according to predetermined compression rate (CR) and discard interval length (DIL). Fifteen middle-aged (42-54 years old) and 15 older (60-69 years old) adults participated in the study that assessed the combined effects of CR and DIL on the comprehension of time-compressed speech by agin...

This paper presents the Discrete Wavelet Transform (DWT) for real-world speech compression design by using the Field Programmable Gate Array (FPGA) device. Compared with many reports which only focused on the DWT architecture design, this paper gives the speech compression system design detail on how to interface DWT block with SDRAM and audio codec chip. Speech compression was achieved by keep...

With as few as 10-20 sentences of exposure, listeners are able to adapt to speech that is highly distorted compared to that which is encountered in everyday conversation. The current study examines the extent to which adaptation to time-compressed speech can be impeded by disrupting the continuity of the exposure sentences, and whether this differs between young and older adult listeners when t...

 Background: According to previous studies, most of the speech recognition disorders in older adults are the results of deficits in audibility and auditory temporal resolution. In this paper, the effect of ageing on timecompressed speech and auditory temporal resolution by word recognition in continuous and interrupted noise was studied. Methods: A time-compressed speech test (TCST) w...
