“…Thus, overall syllable duration, together with information carried by the formant transitions, was sufficient to cue vowel identity in most instances. Other deletion studies have generally produced similar findings (Blumstein & Stevens, 1980;Jenkins, Strange, & Edman, 1983;Kuehn & Moll, 1972;Ohde & Sharf, 1977;Tekieli & Cullinan, 1979;Winitz, Scheib, & Reeds, 1972).…”

Listeners were asked to identify natural vowels in Id_d/ context under various deletion conditions. Deletion intervals, which were centered about the syllable midpoint, ranged from 60% to 90% of the syllable duration and contained either silence or broadband noise. In one condition, the three syllable types were Idid/, Ided/, and Idud/; in the other condition, the three syllable types were /dld/, /ded/, and/dxd/, Identification performance in the 60% and 70% deletion conditions was not substantially worse than for full syllables. Even the 90% deletion conditions yielded performance well above chance, indicating that significant coarticulatory information for vowels is contained in the first and last 10 or 15 msec of the syllable. For the short-vowel stimuli (fdId/, /ded/, and IdAd/) in the 90% deletion condition, a series of discriminant analyses were performed to assess the relative contribution of several acoustic variables to the statistical separation of the vowel categories. Several different combinations of acoustic variables (including formant frequencies at particular temporal locations and formant frequency differences over time) were sufficient to yield significant separation of the three vowel categories. However, in general, the performance ofthe discriminant classification program correlated only weakly with the identification performance of the listeners.

“…Nevertheless, such a psychophysically based account cannot fully account for adults' perception of place of articulation at a phonetic level-particularly in light of the nondistinctiveness of formant transition information within certain vowel contexts in natural speech (e.g., Dorman et al, 1977;Kewley-Port, 1982;Ohde and Sharf, 1977). Awareness of such nondistinctiveness, together with the contextual variability of formant transitions and release bursts, is what has recently prompted several researchers to seek new and invariant descriptions of the acoustic correlates of stop consonants (in addition to the work of Stevens and Blumstein, see Kewley-Port, 1980, 1982, 1983Searle et al, 1979Searle et al, , 1980.…”

According to recent theoretical accounts of place of articulation perception, global, invariant properties of the stop CV syllable onset spectrum serve as primary, innate cues to place of articulation, whereas contextually variable formant transitions constitute secondary, learned cues. By this view, one might expect that young infants would find the discrimination of place of articulation contrasts signaled by formant transition differences more difficult than those cued by gross spectral differences. Using an operant head-turning paradigm, we found that 6-month-old infants were able to discriminate two-formant stimuli contrasting in place of articulation as well as they did five-formant + burst stimuli. Apparently, neither the global properties of the onset spectrum nor simply the additional acoustic information contained in the five-formant + burst stimuli afford the infant any advantage in the discrimination task. Rather, formant transition information provides a sufficient basis for discriminating place of articulation differences.

“…Such a phenomenon is referred to as ‘anticipatory coarticulation'. At the perceptual level, studies have shown that anticipatory cues are functional in speech perception [1,2,3]. Indeed, they provide listeners with indices about the upcoming vowel.…”

Objective: It has been shown previously that congenitally blind francophone adults had higher auditory discrimination scores than sighted adults. It is unclear, however, if, compared to their sighted peers, blind speakers display an increased ability to detect anticipatory acoustic cues. In this paper, this ability is investigated in both speaker groups. Methods: Using the gating paradigm, /izi/ and /izy/ sequences were truncated to include a variable duration of the vowel. The sequences were used as stimuli in an auditory identification test. Seventeen congenitally blind adults (9 females and 8 males) and 17 sighted controls were recruited. Their task was to identify the second vowel of the sequence. Results: Results show that all participants could reliably identify the rounded vowel prior to its acoustic onset, but steeper identification slopes were found for sighted listeners than for blind listeners. Conclusion: The difference in identification slopes likely suggests that sighted speakers display finer abilities to perceptually follow the decreasing values of the frication noise, compared to blind speakers.
