Comparing word-level intelligibility after linear vs. non-linear time-compression
نویسنده
چکیده
In this paper the question is addressed whether the word-level intelligibility of time-compressed speech can be improved over linear compression by using a type of non-linear compression. Two options are tested: one type of compression which takes into account the natural timing of fast speech; and one other type of compression that saves the segmental intelligibility of short unstressed syllables. This is tested at two rates of speech: fast and very fast. The results of the perception experiments (an articulation test and a speechinterference test) show that, at both rates of speech, neither of the two types of non-linear time-compression improves intelligibility over linear compression. This suggests that both the prosodic pattern and the segmental intelligibility of both syllables contribute to word recognition in fast speech.

Intelligibility of time-compressed speech: three ways of time-compression
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...

The recruitment phenomenon, that is, the reduced dynamic range between threshold and uncomfortable level, is attributed to the loss of instantaneous dynamic compression on the basilar membrane. Despite this, hearing aids commonly use slow-acting dynamic compression for its compensation, because this was found to be the most successful strategy in terms of speech quality and intelligibility reha...

In this study we investigate whether speakers, in line with the predictions of the Hyperand Hypospeech theory, speed up most during the least informative parts and less during the more informative parts, when they are asked to speak faster. We expected listeners to benefit from these changes in timing, and our main goal was to find out whether making the temporal organisation of artificially ti...

In this paper we analyse the effect of speech corpus and compression method on the intelligibility of synthesized speech at fast rates. We recorded English and German language voice talents at a normal and a fast speaking rate and trained an HSMMbased synthesis system based on the normal and the fast data of each speaker. We compared three compression methods: scaling the variance of the state ...
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...
