The effect of procedural variations on the S/Z ratio of adults.
The effect of elicitation order, number of required trials, and selection of /s/ and /z/ values utilized to calculate the s/z ratio in adult subjects was examined. Results support the conclusion that a single phoneme production trial is a valid and efficient method for obtaining the s/z ratio. Procedural and clinical implications are discussed.
