A model of the visual similarity of monosyllabic words.
Houston, Kevin Todd.

A model of the visual similarity of monosyllabic words. - 81 p.

Major Professor: Allen A. Montgomery.

Thesis (Ph.D.)--University of South Carolina, 1999.

This study attempted to develop a model of the salient visible articulatory characteristics of monosyllabic English words. Monosyllabic words were selected as the smallest meaningful unit that displays coarticulation when spoken. The study was conducted in two phases. The model was developed from the mean judgments of visual similarity of pairs of words from a talker on videotape. The model was based on a set of articulatory weights which described the visible articulation of 165 primitive phonemes. These primitives were then subjected to a coarticulation algorithm which yielded phonetic forms of monosyllables. A second algorithm was then generated to provide an estimate of the visual similarity of phonetic word pairs. The model was modified iteratively to maximize the correlation between the similarity estimates from the model and mean similarity estimates obtained from the subjects viewing a carefully-selected set of 235 word pairs. A maximum similarity of 0.86 was obtained.

520 $a This study attempted to develop a model of the salient visible articulatory characteristics of monosyllabic English words. Monosyllabic words were selected as the smallest meaningful unit that displays coarticulation when spoken. The study was conducted in two phases. The model was developed from the mean judgments of visual similarity of pairs of words from a talker on videotape. The model was based on a set of articulatory weights which described the visible articulation of 165 primitive phonemes. These primitives were then subjected to a coarticulation algorithm which yielded phonetic forms of monosyllables. A second algorithm was then generated to provide an estimate of the visual similarity of phonetic word pairs. The model was modified iteratively to maximize the correlation between the similarity estimates from the model and mean similarity estimates obtained from the subjects viewing a carefully-selected set of 235 word pairs. A maximum similarity of 0.86 was obtained.
520 $a The final form of the model was evaluated using a different set of 241 pairs of words, selected randomly from a large database of monosyllabic words. Mean human judgments of the similarity of these word pairs were obtained from 25 new observers. The correlation between the model's similarity estimates and the human judgments was 0.80. When the effect of coarticulation was removed, the correlation dropped significantly to 0.74 (Z = 2.68, p. < 0.01). These results suggested the model was successful in predicting the visible similarity of monosyllabic words and that coarticulation played a role in visual similarity of words.
