Time-Interval Measurement of Stuttering

Journal of Speech, Language, and Hearing Research, 1994
The study reported in this article used a binary forced-choice judgment procedure to investigate the effects of sample duration on observers’ judgments of stuttering. Two groups of judges, differing in their previous experience with stuttering, categorized 270 speech intervals as stuttered or nonstuttered; the intervals were drawn from 30 persons who ...

Picosecond time interval measurements

IEEE Transactions on Instrumentation and Measurement, 1995
Efficient measurement techniques have been developed to adequately characterize the performance of a new generation of programmable equivalent time sequential sampling oscilloscopes. These instruments provide time interval measurements with increased repeatability and accuracy.

On time interval measurements using BCG

2012 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2012
Time intervals measured between the electrocardiogram (ECG), the photoplethysmogram (PPG) or the impedance plethysmogram (IPG), have long been used to noninvasively assess cardiovascular function. Recently, the ballistocardiogram (BCG) has been proposed as an alternative physiological signal to be used in time interval measurements for the same purpose.

Time-Interval Measurement of Stuttering

Journal of Speech, Language, and Hearing Research, 1993
This paper reports the results of two experiments that investigated interval-by-interval inter and intrajudge agreement for stuttered and nonstuttered speech intervals (4.0 sec). The first experiment demonstrated that interval-by-interval interjudge agreement could be significantly improved, and to satisfactory levels, by training judges to ...
