Abstract [en]

To meet the need for a linguistic speech perception test in Swedish, the ‘Listen-Say test’ was developed. Minimal word pairs were used as speech material to assess seven phonetic contrasts in two auditory backgrounds. In the present study, children’s speech discrimination skills in quiet and in four-talker (4T) speech background were examined. Associations with lexical-access skills and academic achievement were explored. The study included 27 school children 7–9 years of age. Overall, the children discriminated phonetic contrasts well in both conditions (quiet: Mdn 95%; 4T speech; Mdn 91% correct). A significant effect of 4T speech background was evident in three of the contrasts, connected to place of articulation, voicing and syllable complexity. Reaction times for correctly identified target words were significantly longer in the quiet condition, possibly reflecting a need for further balancing of the test order. Overall speech discrimination accuracy was moderately to highly correlated with lexical-access ability. Children identified as having high concentration ability by their teacher had the highest speech discrimination scores in both conditions followed by children identified as having high reading ability. The first wave of data collection with the Listen-Say test indicates that the test appears to be sensitive to predicted perceptual difficulties of phonetic contrasts particularly in noise. The clinical benefit of using a procedure where speech discrimination, lexical-access ability and academic achievement are taken into account is discussed as well as issues for further test refinement.

Abstract [en]

Our aim was to explore whether a multi-feature paradigm (Optimum-1) for eliciting mismatch negativity (MMN) would objectively capture difficulties in perceiving small sound contrasts in children with hearing impairment (HI) listening through their hearing aids (HAs) and/or cochlear implants (CIs). Children aged 5-7 years with HAs, CIs and children with normal hearing (NH) were tested in a free-field setting using a multi-feature paradigm with deviations in pitch, intensity, gap, duration, and location. There were significant mismatch responses across all subjects that were positive (p-MMR) for the gap and pitch deviants (F(1,43) = 5.17, p = 0.028 and F(1,43) = 6.56, p = 0.014, respectively) and negative (MMN) for the duration deviant (F(1,43) = 4.74, p = 0.035). Only the intensity deviant showed a significant group interaction with MMN in the HA group and p-MMR in the CI group (F(2,43) = 3.40, p = 0.043). The p-MMR correlated negatively with age, with the strongest correlation in the NH subjects. In the CI group, the late discriminative negativity (LDN) was replaced by a late positivity with a significant group interaction for the location deviant. Children with severe HI can be assessed through their hearing device with a fast multi-feature paradigm. For further studies a multi-feature paradigm including more complex speech sounds may better capture variation in auditory processing in these children.

Abstract [en]

The present study explored nonword repetition (NWR) and nonword decoding in normalhearing (NH) children and in children with cochlear implants (CIs). Participants were 11 children with bilateral CIs, 5:0-7:11 years (M = 6.5 yrs.), and 11 NH children, individually age-matched to the children with CIs. The purpose was twofold; to thoroughly describe aspects of repetition and decoding of novel words and to study possible associations between them. All children were assessed after having practiced with a computer-assisted reading intervention with a phonics approach during four weeks. Results showed that NH children outperformed children with CIs on the majority of aspects of NWR. The analysis of syllable length in NWR revealed that children with CIs made more syllable omissions than did the NH children, and predominantly in prestressed positions. Additionally, the consonant cluster analysis showed significantly more consonant omissions and substitutions in children with CIs suggesting that reaching fine- grained levels of phonological processing was particularly difficult for these children. No significant difference was found for decoding accuracy between the groups, as measured by percent nonwords and percent phonemes correctly decoded, but differences were observed regarding error patterns. Further, phoneme deletions and lexicalizing of nonwords occurred more often in children with CIs than in those with NH. The correlation analysis revealed that the ability to repeat consonant clusters in NWR had the strongest associations to nonword decoding in both groups.
