Using a notebook computer to estimate single word intelligibility in aphasic and apraxic speakers

By K.L. Haley and A. Diakaki

We examined the clinical viability of using a multimedia notebook computer to assess speech intelligibility in persons with aphasia and apraxia of speech (AOS). Single-word productions were elicited through simultaneous presentation of the written word on a computer screen and live models produced by an examiner. An external microphone and standard sound recorder were used to capture the signal. Through the sound recorder function, recorded productions were subsequently presented for identification to a panel of normal listeners. The recording protocol effectively elicited and captured productions from all participants. Speakers with aphasia and AOS produced a range of intelligibility scores substantially below the range produced by a normal control group. Test-retest and inter-observer reliability estimates were satisfactory. Suggestions for further improvement of the assessment protocol are discussed.
