Comparing Audio and Visual Information for Speech Processing
Dean, David B., Lucey, Patrick J., Sridharan, Sridha, & Wark, Timothy J. (2005) Comparing Audio and Visual Information for Speech Processing. In Eighth International Symposium on Signal Processing and Its Applications, 28-31 August 2005, Sydney, Australia.
This paper examines the utility of audio-visual speech for the two related tasks of speech and speaker recognition. A study of the confusion that exists between speaker and speech elements was performed to show that principal component analysis (PCA) based visual speech is considerably better for the task of speaker recognition than for speech. Decision fusion speech and speaker recognition engines were also tested under various levels of acoustic degradation to find that the optimal fusion configuration for speaker recognition was substantially different than that for speech. These results highlight the problem of employing similar visual features for both speech and speaker recognition.
Impact and interest:
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
