It has been noted that the speech of adults who become deaf can deteriorate, particularly in terms of suprasegmental features. The speech production skills of 30 post-lingually deafened adults who had derived no benefit from hearing aids was assessed before and after cochlear implantation using subjective and objective measures. Significant improvement in speech production was heard in 57 per cent of subjects; 29 subjects were judged to have improved speech production after using their cochlear implant for one year.
