✦ Synopsis

Conclusion

High stimulation rates provide better temporal resolution and can encode 'periodicity' cues that contribute significantly to tone recognition when few spectral details are available (Fu and Zeng, 2000), as well as when the spectral resolution is relatively high (Xu et al., 2002). The ACE strategy combines the relative advantages of the SPEAK (spectral resolution) and CIS (higher rate of stimulation) strategies. In the present study, ACE strategies produced the highest speech-recognition scores whereas the SPEAK and CIS-4 strategies produced the lowest scores. The data suggest that relatively higher stimulation rates (> 900 Hz) and a greater number of stimulating electrodes may improve Mandarin speech recognition. The higher stimulation rates provided by the latest-generation cochlear implant systems fitted with the ACE or CIS strategies are better suited for Mandarin speech recognition than implant systems that employ lower stimulation rates.
