The Spectra 22 Speech Processor and spectral peak (SPEAK) speech-coding strategy provide
Nucleus 22 Channel Cochlear Implant (Cochlear, Corp., Englewood, Colo.) users with a
better understanding of speech than the previous Mini Speech Processor and Multipeak
(MPEAK) speech-coding strategy. On the NU-6 Monosyllabic Word Test, subjects scored 13%
higher for words and 14% higher for phonemes with the SPEAK strategy than with the MPEAK
strategy. On the Connected Speech Test and the CID Everyday Sentence Test, subjects scored
32% and 37% higher, respectively, with SPEAK than with MPEAK.
