Twenty-three speech-language pathologists (SLPs) experienced with thickening liquids for dysphagia evaluations were asked to mix solutions comparable to their perceptions of nectar, honey, and pudding consistencies. The purpose of the study was to determine if these professionals were able to reliably repeat their relative perceptions of nectar, honey, and pudding over multiple mixings. Each mixed solution was analyzed using a viscometer to determine its actual viscosity. A replication reliability analysis indicated that the professionals were not consistent in their attempts to thicken liquids. Intrasubject results were somewhat better or more consistent than intersubject results. Results of this study indicate the need for a standard protocol during dysphagia management to ensure consistent viscosities across evaluation and treatment.

A program for the automatic extraction of jitter (PAEJ) was developed for the clinical measurement of pitch perturbations using a microcomputer. The program currently includes 12 implementations of an algorithm for marking the boundary criteria for a fundamental period of vocal fold vibration. The relative sensitivity of these extraction procedures for identifying the pitch period was compared using sine waves. Data obtained to date provide information for each procedure concerning the effects of waveform peakedness and slope, sample duration in cycles, noise level of the analysis system with both direct and tape recorded input, and the influence of interpolation. Zero crossing extraction procedures provided lower jitter values regardless of sine wave frequency or sample duration. The procedures making use of positive- or negative-going zero crossings with interpolation provided the lowest measures of jitter with the sine wave stimuli. Pilot data obtained with normal-speaking adults indicated that jitter measures varied as a function of the speaker, vowel, and sample duration.
