This study investigated the effect of degraded listening conditions and speech rate on children’s answer accuracy and response time in a speech perception task. Fifty-three normally-developing children (aged 5-6 years) listened to 72 pseudo-word pairs presented at two different speech rates (normal and fast) and four different listening conditions (healthy voice in silence [control], hoarse voice in silence, healthy voice in speech-shaped noise (SSN) at 0 dBA SNR, and hoarse voice in SSN at 0 dBA SNR). The participants had to decide whether the words were the same (e.g. /filam/ - /filam/) or different (e.g. /mafin/ - /nafin/). For either speech rate, degraded listening conditions were found to significantly decrease answer accuracy and increase response times. Regarding response time, speech rate interacted with listening condition: At fast (as opposed to normal) speech rate, children responded slower to healthy voice in SSN but faster to the three other listening conditions. Our findings suggest that speech signal degradations may disrupt children’s speech perception even at normal speed. Speech rate might influence the extent of listening effort associated with different listening conditions. A good quality and adequate transmission of the speech signal may help children to listen effectively.
