Abstract [sv]

Nedsatt talperception förekommer hos flera grupper barn som besöker audiologisk och logopedisk klinik. Dessa är exempelvis barn med språkstörning, barn med kognitiva nedsättningar, barn med hörselnedsättningar och barn med (centrala) auditiva bearbetningsnedsättningar (CAPD). För närvarande saknas standardiserade talperceptionstest som ger information om hur barn diskriminerar, identifierar och producerar språkljudskontraster i ord. Det är därför av stor vikt att utveckla diagnosverktyg för att öka möjligheten till ett reliabelt testförfarande och differentialdiagnostisering. Föreliggande studie hade 2 syften. Dels att färdigställa och standardisera ett nytt talperceptionstest, Lyssna-Säg. Dels att pröva hur typisktutvecklade barn i åk 1 och 2 presterade i betingelserna tyst och babbel. Studien inkluderade 21 barn och visade att barnen diskriminerade signifikant fler korrekta konsonantkontraster i tyst jämfört med babbel för alla konsonantkontraster sammanslaget. Skillnader i resultat observerades även mellan några av de konsonantkontraster som undersöktes, såväl mellan betingelserna tyst och babbel samt mellan årskurserna, där årskurs 2 presterade bättre. Likaså observerades signifikant kortare svarstid för korrekt identifierade målord i babbel än i tyst. Studien visade att det är nödvändigt att utveckla testet ytterligare inför användning i klinisk verksamhet. Likväl har den första datainsamlingen kunnat belysa viktiga aspekter om hur barns talperception av svenska konsonantkontraster i betingelserna tyst och babbel ser ut.

Abstract [en]

Impaired speech perception occurs in several groups of children enrolled at Speech Language Pathology and Audiological clinics. There may be children with language impairment, cognitive impairments, hearing impairments and children with (Central)Auditory Processing Disorders (CAPD). At present no standardized speech perceptiontest in Swedish provides information about how children discriminate, identify and produce speech sound contrasts in words. It is therefore of great importance to develop diagnostic tools to obtain a reliable test procedure and enable differential diagnostics.The present study had two purposes, to prepare and standardize a new speech perceptiontest (the Listen-Say test) and to investigate how typically developing children in grade 1 and 2 perform in quiet and in babble noise. The study included 21 children. Results showed that the children discriminated significantly more correct consonant contrasts inquiet compared to babble noise for all consonant contrasts combined. The study alsoshowed differences in some of the contrasts that were examined, both between quiet andbabble noise and between grades, grade 2 discriminated more correct contrasts thangrade 1. Significantly shorter reaction times for correct recognition of target words inbabble noise compared to quiet was observed. It is necessary to develop the test additionally prior to use in clinical practice. Nevertheless, the first data collection highlights important aspects of speech perception of Swedish consonant contrasts inquiet and in babble noise.
