Since speech is a continuous stream with no systematic boundaries between words, how do pre-verbal infants manage to discover words? A proposed solution is that they might use the transitional probability between adjacent syllables, which drops at word boundaries. Here, we tested the limits of this mechanism by increasing the size of the word-unit…

In an attempt to understand what acoustic/auditory feature sets motivated transcribers towards certain labeling decisions, I built machine learning models that were capable of discriminating between canonical and non-canonical vowels excised from the Buckeye Corpus. Specifically, I wanted to model when the dictionary form and the transcribed-form…

An experienced person, in such tasks as sonar detection and recognition, has a considerable superiority over a machine recognition system in auditory pattern recognition. However, people require extensive exposure to auditory patterns before achieving a high level of performance. In an attempt to discover a method of training people to recognize…

Two experiments involving a total of 177 infants 8 to 11 months of age found that subjects used a global processing strategy like adults' in discriminating transformations of a six-tone melody. Subjects needed melodic contour and frequency range to judge new sequences, but, in easy tasks, they also used absolute frequency. (CB)

Assessed the ability of 5-month-old infants to discriminate between auditory tone patterns differing in temporal arrangement but utilizing the same component tones. Heart rate change provided the measure of pattern discrimination. (JMB)

Auditory pattern recognition skills in children with reading disorders were investigated using perceptual tests involving discrimination of frequency and duration tonal patterns. A behavioral test battery involving recognition of the pattern of presentation of tone triads was used in which individual components differed in either frequency or…

An investigation to account for age changes in the accuracy with which children match auditory to visual series. (Author)
