The aim of this study was to determine which land line telephone and/or

mobile/cellular telephone will enable an individual with a cochlear implant to

achieve the best speech discrimination scores. Objective measurements and the

subjective experience of the individual were used. The literature review provided

an overview on the telephone abilities of individuals fitted with cochlear implants.

In this study three factors, the quality of the telephone, the speaker's voice and

different speech-coding strategies, were discussed and examined, in order to

explore and explain the technical difficulties commonly experienced by this

population regarding the successful use of a telephone. Data regarding various

telephones and the influence different voice-types has on the telecommunication

abilities were obtained through the execution of the methodology. Telephone

abilities on five different telephones were assessed.

Ten participants, four

females and six males, fitted with the ESPrit 22, ESPrit 24 and ESPrit 3G

Nucleus cochlear implants were used. The Central Institute for the Deaf (CID)

open-set sentences were used and data was statistically analysed using a split

plot design. Significant differences between different types of telephones were

found. The results also suggested that different voice types have an impact on

these individual's ability to use a telephone independently. Possible reasons

such as different coding strategies, technical interference and quality of voices

were discussed. Recommendations for developing rehabilitation programs, to

obtain successful telephone competence for these individuals, were made and

discussed. The study aimed to empower technologists working in this field to

actively take note of the need for development and continuous research

regarding various telephones. These telephones should enable more individuals

fitted with cochlear implants to receive the maximum speech discrimination with

the minimum interference. The findings of this study should encourage future

research regarding this topic. A more extensive range of telephones should be

used and compared to the findings in this study.
