The Utah‐design multichannel cochlear Implant consists of six intracochlear monopolar electrodes, one promontory electrode, and an indifferent electrode. Connection of the intracochlear system to the external sound processor is via a percutaneous pedestal system. Four of the intracochlear electrodes receive simultaneous stimulation. Twenty patients implanted at the University of Utah with more than 1 year of sound processor use were evaluated for the study. All patients wear their sound processors on a daily basis. Seven of the 20 are able to use the telephone without special devices. Nineteen patients were tested with open set CID sentences with an average 42.2% response. A comparison was made between live voice and taped voice open‐set spondee word list performance, showing slightly better overall performance with live voice.
