“…The error pattern analysis in this study revealed that T2 and T3 were mainly misidentified as each other. The confusion between T2 and T3 was in line with prior reports that examined pediatric Mandarin-speaking CI users' lexical tone perception in quiet [21,37]. One known source for the confusion between Mandarin T2 and T3 is the acoustic similarity of the two tones [58].…”

“…While CI users can significantly benefit from the neuroplasticity driven by the CI-empowered learning experience in developing their auditory, linguistic, and cognitive skills [3][4][5][6][7][8][9], pitch perception poses a unique challenge for these individuals. A vast body of literature demonstrated that CI recipients show deficits in pitch-related perceptual tasks, including voice emotion perception [10][11][12], speech prosody recognition [13][14][15], music appreciation [16][17][18], and lexical tone perception [19][20][21]. One known factor here lies in the limitations of the contemporary CI multichannel technology that encodes degraded spectral-temporal signals of the auditory input.…”

“…Prior studies have demonstrated that T1 and T4 are significantly easier to perceive than T2 and T3 for native CI children, with more confusion between the identification of T2 and T3 [21,37]. However, it is still an open question whether additional acoustic hearing from the non-implanted ear with an HA has the potential to enhance the representation of different tone patterns and to alleviate the confusion between T2 and T3.…”

Bimodal Benefits for Lexical Tone Recognition: An Investigation on Mandarin-speaking Preschoolers with a Cochlear Implant and a Contralateral Hearing Aid

Pitch perception is known to be difficult for individuals with cochlear implant (CI), and adding a hearing aid (HA) in the non-implanted ear is potentially beneficial. The current study aimed to investigate the bimodal benefit for lexical tone recognition in Mandarin-speaking preschoolers using a CI and an HA in opposite ears. The child participants were required to complete tone identification in quiet and in noise with CI + HA in comparison with CI alone. While the bimodal listeners showed confusion between Tone 2 and Tone 3 in recognition, the additional acoustic information from the contralateral HA alleviated confusion between these two tones in quiet. Moreover, significant improvement was demonstrated in the CI + HA condition over the CI alone condition in noise. The bimodal benefit for individual subjects could be predicted by the low-frequency hearing threshold of the non-implanted ear and the duration of bimodal use. The findings support the clinical practice to fit a contralateral HA in the non-implanted ear for the potential benefit in Mandarin tone recognition in CI children. The limitations call for further studies on auditory plasticity on an individual basis to gain insights on the contributing factors to the bimodal benefit or its absence.

“…It is possible that deaf infants with CIs may develop different cue-weighting and speech-processing strategies due to early auditory deprivation and subsequent degraded speech input. For example, in a recent study, Peng et al (2017) examined acoustic cue processing in CI recipients in a lexical tone recognition task. These CI recipients were prelingually deaf native Mandarin speakers who were between 6.6 and 21.4 years old.…”

Purpose: Both theoretical models of infant language acquisition and empirical studies posit important roles for attention to speech in early language development. However, deaf infants with cochlear implants (CIs) show reduced attention to speech as compared with their peers with normal hearing (NH; Horn, Davis, Pisoni, & Miyamoto, 2005;Houston, Pisoni, Kirk, Ying, & Miyamoto, 2003), which may affect their acquisition of spoken language. The main purpose of this study was to determine (a) whether infantdirected speech (IDS) enhances attention to speech in infants with CIs, as compared with adult-directed speech (ADS), and (b) whether the degree to which infants with CIs pay attention to IDS is associated with later language outcomes. Method: We tested 46 infants-12 prelingually deaf infants who received CIs before 24 months of age and had 12 months of hearing experience (CI group), 22 hearing experience-matched infants with NH (NH-HEM group), and 12 chronological age-matched infants with NH (NH-CAM group)-on their listening preference in 3 randomized blocks: IDS versus silence, ADS versus silence, and IDS versus ADS. We administered the Preschool Language Scale-Fourth Edition (PLS-4; Zimmerman, Steiner, & Pond, 2002) approximately 18 months after implantation to assess receptive and expressive language skills of infants with CIs. Results: In the IDS versus silence block, all 3 groups looked significantly longer to IDS than to silence. In the ADS versus silence block, both the NH-HEM and NH-CAM groups looked significantly longer to ADS relative to silence; however, the CI group did not show any preference. In the IDS versus ADS block, whereas both the CI and NH-HEM groups preferred IDS over ADS, the NH-CAM group looked equally long to IDS and ADS. IDS preference quotient among infants with CIs in the IDS versus ADS block was associated with PLS-4 Auditory Comprehension and PLS-4 Expressive Communication measures. Conclusions: Two major findings emerge: (a) IDS enhances attention to speech in deaf infants with CIs; (b) the degree of IDS preference over ADS relates to language development in infants with CIs. These results support a focus on input in developing intervention strategies to mitigate the effects of hearing loss on language development in infants with hearing loss.

Previous investigations found that loudness-contours within individual Mandarin monosyllables can drive categorical perception of Mandarin tone for cochlear implant (CI) users, while in normal hearing (NH) subjects the pitch contour is phonologically acknowledged to be the dominant cue. Here we further examine the weighting strategy of pitch induced and loudness induced contour identification on Mandarin tone perception by CI users. Twenty-seven versions of the disyllabic utterance /Lao3 Shi/ with orthogonally manipulated loudnesscontour and pitch-contour of the voiced portion of the second monosyllable /Shi/ served as the stimuli to both CI and NH subjects. In Mandarin, if /Shi/ is pronounced with high-flatpitched Tone 1 the word means "teacher", with rising Tone 2 it means "well-behaved", or with falling Tone 4 it means "always". CI users generally had poorer word-recognition scores and their inter-subject variance was large. While NH subjects recognized tone reliably based on pitch-contour, half of the CI users relied on pitch-contour, the other half on loudness-contour, implying systematic differences in pitch coding in their CI processing. This paradigm of orthogonal manipulation of pitch and loudness contours could be developed into improved audiometric tests of Mandarin tone perception and pitch coding with CIs.

Processing of Acoustic Cues in Lexical-Tone Identification by Pediatric Cochlear-Implant Recipients

Abstract: For pediatric CI recipients, lexical-tone recognition using naturally uttered words is primarily related to their reliance on F0 contours, although duration patterns may be used as an additional cue.
