Random Generation of Apparent Speech Rhythms

Abstract: In order to illustrate the misinterpretation of time series data, simulated temporal patterns of vocalizations and pauses were generated from a table of random digits. These data exhibited precisely those characteristics which, when seen in graphs of actual spontaneous speech, have heretofore been taken as evidence for cognitive planning. This concretizes a previously made point concerning the need to distinguish random process from causal connection.

“…The Henderson procedure has been criticised because of its reliance on subjective methods (Jaffe, Breskin, & Gertsman, 1972;Kowal & O'Connel, 1985;Power, , 1984Rochester, 1973;Schwartz & Jaffe, 1968). Kowal and O'Connel point out that unless descriptive or inferential statistics are provided, the possibility that temporal cycles re ect random variation cannot be discounted.…”

“…Schwartz and Jaffe (1968) argued that in any sequence of random events runs would occur such that, arbitrarily, one can always nd substances that give an apparent structure to the sequence of events. Jaffe et al (1972) generated time series of random speech and pause durations. When lines were tted to the plots using the Henderson procedure temporal cycles were detected by human judges.…”

“…Cycle times have been found to range between 10.6 and 39.2 s.ec, with a mean of 18.0 sec (Butterworth, 1975) which suggests that such units are substantially larger than individual clauses. The evidence for these cycles has, however, been called into question by Jaffe, Breskin and Gerstman (1972) who demonstrated that cycles could be discerned in randomly generated pause-phonation series. It was also found in the simulated speech as well as in real spontaneous speech that the longer the pause time in the steep (hesitant) slope, the longer the phonation time in the succeeding shallow (fluent) slope.…”

“…The editors' hopes are further dashed by the willingness of the authors (Beebe, Stern & Jaffe, and Hayes & Cobb) to claim regularities ("kinesic rhythms" and "ultradian rhythms" respectively) for which they have no statistical evidence and which their illustrations make dubious. Co-author Jaffe's role in debunking Goldman-Eisler's earlier claims regarding rhythms (Jaffe, Breskin, & Gerstman 1972) regrettably did not prepare him to take an equally skeptical position here.
