Subject: Re: piano sounds to speech and whisper magic From: "Richard M. Warren" <rmwarren@xxxxxxxx> Date: Mon, 12 Oct 2009 15:23:59 -0500 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--Apple-Mail-13-46448647 Content-Type: text/plain; charset=US-ASCII; format=flowed; delsp=yes Content-Transfer-Encoding: 7bit While perhaps not as much fun as changing piano sounds to speech, sometime ago Jim Bashford and I reported a slight of band that makes it possible to transform intelligible whispered discourse to an intelligible voiced monotone. This magic was accomplished by excising a 4 ms segment of the whispered speech and repeating it three times to produce four statements lasting 16 ms; then capturing another 4 ms of whisper which was repeated to produce another set of 4 statements, etc. The resulting voiced speech was quite intelligible despite the discard of 12 ms speech segments and the nonselective voicing of all phonemes. Presto change-o, it was possible to obtain a sex change by altering the duration of the repeated excised segments from 4 to 8 ms, and to avoid a monotone by slight variations in the durations of successive iterated captures.
