“…This amounts to dividing attention across two spatial locations and, as Driver (1996) has shown, auditory speech perception can be influenced by shifts in the spatial location of visual attention. Furthermore, a visually presented secondary task can modulate the influence of some auditory speech cues (Gordon, Eberhardt, & Rueckl, 1993). In our data, attentional factors could have had at least two influences on auditory perception.…”

“…Tense vowels are more peripheral in the acoustic vowel space (i.e., lower F1, and higher F2 and F3 values) and longer in duration relative to lax vowels (Ladefoged, 2001). Although native English speakers use predominantly spectral properties both in perception and production of these vowels, they are able to identify tense and lax vowels based on their duration alone when the stimuli are spectrally ambiguous (Gordon et al, 1993). Thus, in order to understand better how maternal input can benefit infants' acquisition of speech contrasts, it is necessary to investigate whether the modification of acoustic characteristics of ID speech occurs simultaneously along all available dimensions that may characterize a speech contrast or only the primary ones that serve distinctive (phonological) roles in the native language.…”

Recent studies have demonstrated that mothers exaggerate phonetic properties of infant-directed (ID) speech. However, these studies focused on a single acoustic dimension (frequency), whereas speech sounds are composed of multiple acoustic cues. Moreover, little is known about how mothers adjust phonetic properties of speech to children with hearing loss. This study examined mothers' production of frequency and duration cues to the American English tense/lax vowel contrast in speech to profoundly deaf (N ¼ 14) and normal-hearing (N ¼ 14) infants, and to an adult experimenter. First and second formant frequencies and vowel duration of tense (/i/, /u/) and lax (/I/, /U/) vowels were measured. Results demonstrated that for both infant groups mothers hyperarticulated the acoustic vowel space and increased vowel duration in ID speech relative to adult-directed speech. Mean F2 values were decreased for the /u/ vowel and increased for the /I/ vowel, and vowel duration was longer for the /i/, /u/, and /I/ vowels in ID speech. However, neither acoustic cue differed in speech to hearing-impaired or normal-hearing infants. These results suggest that both formant frequencies and vowel duration that differentiate American English tense/lx vowel contrasts are modified in ID speech regardless of the hearing status of the addressee.

“…Another possible role of attentional shifting in speech processing is its involvement in cue weighting to improve contrast sensitivity with discriminant (strong) cues being given priority (Gordon et al, 1993). A related account comes from the attention-to-dimension model (e.g., Francis & Nusbaum, 2002;Goldstone, 1994;Nosofsky, 1986), in which the operations of attending and ignoring represent shifts of attention to or away from acoustic dimensions.…”

“…As reviewed above, attention has been shown to play a role in signal optimization during early processing stage of speech perception (e.g. Gordon et al, 1993;Mattys & Wiget, 2011). However, these studies did not measure individuals' attentional ability, and it remains unclear which components of attention may influence the acoustic analysis during perception.…”

“…The way in which listeners use speech cues to activate phonemes may to some degree be modulated by higher level cognitive processes. For example, the operation of attention in speech perception is proposed to optimize the signal-to-noise ratio in the encoding of acoustic cues (Gordon, Eberhardt, & Rueckl, 1993). Mattys and Wiget (2011) found decreased accuracy in discriminating voice onset time (VOT) differences in the presence of a cognitive load due to dual task compared to a single-task condition, suggesting that detailed phonetic analysis would be compromised if attentional resources are reduced.…”

This study investigated whether individual differences in cognitive functions, attentional abilities in particular, were associated with individual differences in the quality of phonological representations, resulting in variability in speech perception and production. To do so, we took advantage of a tone merging phenomenon in Cantonese, and identified three groups of typically developed speakers who could differentiate the two rising tones (high and low rising) in both perception and production [+Per+Pro], only in perception [+Per-Pro], or in neither modalities [-Per-Pro]. Perception and production were reflected, respectively, by discrimination sensitivity d′ and acoustic measures of pitch offset and rise time differences. Components of event-related potential (ERP)-the mismatch negativity (MMN) and the ERPs to amplitude rise time-were taken to reflect the representations of the acoustic cues of tones. Components of attention and working memory in the auditory and visual modalities were assessed with published test batteries. The results show that individual differences in both perception and production are linked to how listeners encode and represent the acoustic cues (pitch contour and rise time) as reflected by ERPs. The present study has advanced our knowledge from previous work by integrating measures of perception, production, attention, and those reflecting quality of representation, to offer a comprehensive account for the underlying cognitive factors of individual differences in speech processing. Particularly, it is proposed that domain-general attentional switching affects the quality of perceptual representations of the acoustic cues, giving rise to individual differences in perception and production.
