Ordigenkänning i en skadad talsignal. I fokus: Störningsplacering & Betoning

Abstract

The aim of this study was to examine how listeners identify words in a distorted speech signal and what kind of information they use to repair the signal. The relationship between segmental information and stress was closely examined in relation to distortion placement. 21 native Swedish listeners were presented with three-syllable Swedish words that had been distorted at the first, second or third syllable. The stimuli set represented words with natural stress on either the first, second or third syllable. The results indicated an importance of word initial information and that stress had no correspondance with the placement of distortion. Nevertheless, stress and segmental information seemed to play an important role when choosing and identifying possible word candidates for recognition.
