“…Besides from intonation research, the importance of vowel onsets follows from results in other fields of speech perception. Many authors have emphasized the importance of"transients" in general (Cooper et al, 1952;Chistovich et al, 1975;Dorman et aL, 1977;Tekieli and Cull/nan, 1979;Stevens and Blumstein, 1981;Kewley-Port, 1983;Kewley-Port and Luce, 1984;Strange et al, 1983;Studdert-Kennedy, 1985;Furui, 1986). Kewley-Port et al (1983) coneluded that all information about the place of articulation in the transition of a stop consonant to a vowel is confined to a speech segment as short as 2040 ms. Tekieli et al ( 1979} demonstrated that the first 10-30 ms of the vowels of V and CV words contain enough information to allow the vowel to be perceived correctly.…”

An algorithm is presented that correctly detects the large majority of vowel onsets in fluent speech. The algorithm is based on the simple assumption that vowel onsets are characterized by the appearance of rapidly increasing resonance peaks in the amplitude spectrum. Application to carefully articulated, isolated words results in a high number of false alarms, predominantly before consonants that can function as vowels in a different context such as another language or as a syllabic consonant. After applying some modifications in the setting of some parameters, this number of false alarms for isolated words can be reduced significantly, without the risk of a large number of missed detections. The temporal accuracy of the algorithm is better than 20 ms. This accuracy is determined with respect to the perceptual moment of occurrence of a vowel onset as determined by a phonetician.
