Speech-in-Noise Training

Speech perception in the presence of background noise is one of the most affected auditory processes in children diagnosed with and auditory processing disorder (APD). Previous research, however, suggests mixed results regarding the relationship between cognitive skills and speech-in-noise perception of children diagnosed with APD.

In a recent study, Kumar et al (2021) studied the correlation among speech-in-noise perception, gap detection, duration pattern tests, and cognitive skills. They also sought to find the efficacy of speech-in-noise training on these processes. 

Twenty children with APD were included in the study, 10 in an experimental group and 10 served as controls. Training stimuli consisted of monosyllable and trisyllable words in the presence of speech noise and four-talker babble. Outcome measures included five tests of auditory processing and four digit-span tests. 

Results revealed a significant improvement after training on the speech-in-noise measures; temporal processing measures; and the backward, ascending, and descending digit-span measures. There was no correlation within or between auditory and cognitive measures. 

The authors conclude that speech-in-noise training improved temporal processing and working memory skills in children with APD. Combined with previous studies their results may lead to more effective treatment strategies for children with APD.
