Research on amplitude, temporal and spectral cues in speech show that speech recognition is only mildly affected when there in distortions in amplitude or temporal domains. But speech recognition is highly dependent on spectral cues. The present study aimed to find out the combined effects of the two spectral distortions, shift and compression-expansion, on speech recognition. Results from the present study reveal that speech recognition is affected when spectral distortions were present.

Produktbeschreibung
Research on amplitude, temporal and spectral cues in speech show that speech recognition is only mildly affected when there in distortions in amplitude or temporal domains. But speech recognition is highly dependent on spectral cues. The present study aimed to find out the combined effects of the two spectral distortions, shift and compression-expansion, on speech recognition. Results from the present study reveal that speech recognition is affected when spectral distortions were present. Information from the present study on speech recognition in spectrally shifted and compressed-expanded conditions will helps in understanding the sensitivity of speech recognition to spectral manipulations. This will ultimately improve the fitting of an implant speech processor during cochlear implant.
