This paper extends the use of Generalizability Theory to the measurement of extemporaneous L2 speech through the lens of speech perception. Using six datasets of previous studies, it reports on "G studies"--a method of breaking down measurement variance--and "D studies"--a predictive study of the impact on reliability when…

Purpose: Perceptual training is a listener-targeted means for improving intelligibility of dysarthric speech. Recent work has shown that training with one talker generalizes to a novel talker of the same sex and that the magnitude of benefit is maximized when the talkers are perceptually similar. The current study expands previous findings by…

Over the past few decades, there has been considerable effort to find the mechanisms through which adult listeners can accommodate the rampant phonetic variation in natural speech. My dissertation concerns one source of variability: phonetic variation in speech produced by individuals with foreign accents. Mounting evidence shows that listeners…
