“…They [5] investigated whether clear speech produced at high speaking rates could still bring intelligibility benefits over conversational speech and found that it does. [22] also found that clear speech which was linearly compressed to match casual speech speeds was more intelligible than unmodified casual speech.…”

We compare a series of time compression methods applied to normal and clear speech. First we evaluate a linear (uniform) method applied to these styles as well as to naturally-produced fast speech. We found, in line with the literature, that unprocessed fast speech was less intelligible than linearly compressed normal speech. Fast speech was also less intelligible than compressed clear speech but at the highest rate (three times faster than normal) the advantage of clear over fast speech was lost. To test whether this was due to shorter speech duration we evaluate, in our second experiments, a range of methods that compress speech and silence at different rates. We found that even when the overall duration of speech and silence is kept the same across styles, compressed normal speech is still more intelligible than compressed clear speech. Compressing silence twice as much as speech improved results further for normal speech with very little additional computational costs.

“…Here we explore whether the same holds true when compressing other speaking styles. We evaluate the intelligibility of speech compressed using the waveform similarity overlap and add (WSOLA) time compression method [19] to illustrate a linear, also referred to as uniform, compression as was evaluated in [9,18,22].…”
