Gross Estimation: A Study Of The Clinical Validity For Measuring Intelligibility, Heather Gail Clarke

Dissertations and Theses

Intelligibility is the most fundamental factor for successful speech communication. Measurements of speech intelligibility carry important clinical consequences that relate to description of severity, need for intervention, intervention goals, service delivery options, and treatment efficacy. It is important, therefore, that speech-language pathologists use an approach that reflects an accurate and valid measure of intelligibility. The purpose of this study was to investigate the relationship between the two seemingly most common procedures used by practicing speech-language pathologists for measuring speech intelligibility: the gross estimation of intelligibility procedure, and the orthographic transcription procedure. Twelve 100-word connected speech samples were analyzed by 4 …

Comparison Of Intelligibility Estimation And Orthographic Transcription Methods By Preprofessional Speech-Language Pathologists, Kristi M. Mowe

Dissertations and Theses

When the fundamental means of communications is speech, the main component for successful communication is intelligibility. The speech of children with disordered phonologies is often unintelligible; therefore, accurate and reliable methods of measuring intelligibility are essential when determining eligibility, and in selecting and providing appropriate treatment.

The purpose of this study was to investigate the relationship between the percentage estimation method and the orthographic transcription method when measuring speech intelligibility by preprofessional listeners. For this study, the standard measurement of intelligibility was defined as the percentage of words understood in a continuous speech sample derived from orthographic transcription of the …
