“…Our failure then to observe any differences in discrimination performance for the two types of stimuli suggests that infants are not any more sensitive to global, invariant properties of the CV syllable onset spectrum than they are to local details of the waveform, such as formant transition information or even quite small spectral differences. This result suggests that Williams and Bush's (1978) conclusion concerning infants' superior discrimination of five-formant + burst stops relative to stops without bursts may have been inaccurate-particularly in light of the interpretative problems associated with their study as we noted earlier.…”

“…Moreover, no conclusions about the relative discriminability of onset spectra and formant transition cues can be made on the basis of this work. A study by Williams and Bush (1978) is suggestive in this respect. With the high-amplitude sucking paradigm, these investigators studied infants' discrimination of synthetic /da/-/ga/ contrasts in which the stimuli either did or did not contain release bursts.…”

“…The assumption that human listeners are innately sensitive to properties of the onset spectra for different places of stop consonant articulation could, as Stevens and Blumstein (e.g., 1978;Blumstein and Stevens, 1979) suggest, account for the ability of prelinguistic infants to discriminate place of articulation differences in synthetic three-formant and three-formant + burst stimuli (Eimas, 1974;Leavitt et al, 1976;Miller and Morse, 1976;Moffitt, 1971;Morse, 1972;Till, 1976;Williams and Bush, 1978). Although previous demonstrations of the infant's ability to discriminate place of articulation differences in stop consonants lend support to Stevens and Blumstein's argument, it is not known whether the onset spectra of the stimuli employed in these studies possessed the critical properties described by Stevens and Blumstein.…”

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.

“…Jerger's (Jerger, Jerger, & Lewis, 1981) work is an exception; she, too, found children's speech perception to be closely related to receptive vocabulary age. Greater attention has been given to developmental effects associated with voicing-onset-time (VOT) and temporal characteristics of the stimuli (Krause, 1978;Simon & Fourcin, 1978;Tallal, 1981;Williams & Bush, 1978;Zlatin & Koenigsknecht, 1975). Developmental perceptual changes have also been demonstrated for synthetic voiced-stop consonants differing in place of articulation (Elliott, Longinotti, Meyer, Raz, & Zucker, 1981).…”

Detection and identification thresholds were obtained for 6-and lO-year-old normal children and normal adults using five-formant synthesized consonant-vowel ([ba]-[da]-[ga)l stimuli. Sixyear-old children were found to have poorer detection than adults, just as they do for pure tones. For the identification task, the slopes of the performance-intensity functions were more shallow for 6-year-old children than for lO-year-olds and adults. Consequently, compared with lO-yearolds and adults, 6-year-old listeners require a greater increase in stimulus intensity above detection threshold to identify these stimuli at a high performance level. The influence of acoustic characteristics of the stimuli on all listeners is also discussed.It has been reported that young children have poorer pure tone sensitivity than adults (e.g

“…[3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] Some of these studies suggest that development of vowel and consonant perception is largely complete in the first few years of childhood -around 5 to 6 years of age, with some aspects refining till the adolescent years; while some studies have reported less than ceiling scores even for children as old as 10 to 12 years. 14,17,19 For normal development of speech perception and production in the early years and for appropriate and typical use of verbal communication through life, the hearing sense needs to be intact.…”

Background: Very few published studies have reported phoneme contrasts in children with and without hearing impairment in Indian languages. The present study is aimed at comparing perception of manner contrasts in 6 to 8 year old Marathi children with normal hearing and those with hearing impairment using hearing aids and cochlear implants. Methods: Two hundred 6 to 8 year olds participated across three groups: 106 with normal hearing (NH), 47 with hearing aids (HA) and 47 with cochlear implants (CI). Perception of four consonant manner contrasts was assessed using a four-alternative, forced choice picture-pointing task using recorded minimal pairs with CVC or CVCV words: a) Stop vs. Fricative; b) Stop vs. Nasal; c) Stop vs. Affricate and d) Aspiration. Results: All NH participants obtained ceiling scores for stop vs. fricative and stop vs. nasal contrasts. NH participants performed significantly better than participants with CI on all contrasts. Performance of HA participants was more variable and significantly poorer than the CI participants. Children implanted at or before 4 years of age and those using CI for more than 2.5 years performed consistently better on all contrasts as compared to those implanted after 4 years of age and using it for less than 2.5 years. Children fitted with HA at or after 2.5 years of age performed consistently better than those fitted before 2.5 years of age. Participants with average hearing aided thresholds 45 dB HL or lower (better) performed better than those with average aided thresholds above 45 dB HL. Conclusions: Normative data on perception of various manner contrasts in Marathi is generated. Phoneme perception skills of children with NH are significantly better than those of children with CI and HA.
