Spontaneous speech recognition using HMMs
This thesis describes a speech recognition system that was built to support spontaneous speech understanding. The system is composed of (1) a front end acoustic analyzer which computes Mel-frequency cepstral coefficients, (2) acoustic models of context-dependent phonemes (triphones), (3) a back-off …

Automatic utterance segmentation in spontaneous speech
As applications incorporating speech recognition technology become widely used, it is desireable to have such systems interact naturally with its users. For such natural interaction to occur, recognition systems must be able to accurately detect when a speaker has finished speaking. This research …

An investigation of primary stress in spontaneous speech for pedagogical purposes
… Two random segments from a collection of spontaneous, native-speaker conversations were analyzed to identify the location of the primary stresses. W. B. Dickerson's (1995) Primary Phrase Stress (PPS) System, a predictive tool for advanced non-native speakers to use in their practice, was …

Effects of Social Reinforcement Versus Tokens on the Spontaneous Speech of Preschoolers
Two studies were conducted on the effects of different reinforcement contingencies on the emission of verbal operants by preschoolers. Six participants, 3 females and 3 males, 3- to 4-years old, were selected to participate in Experiment I. Six participants, 5 females and 1 male, 2- to 4-years-old, …

The stop-like modification of /ð/ : a case study in the analysis and handling of speech variation
Phonetic variation is pervasive in everyday speech. Studying these variations is essential for building acoustic models and lexical representations that effectively capture the variability of speech. This thesis examines one of the commonly-occurring phonetic variations in English: the stop-like …
