An examination of audio-visual fused HMMs for speaker recognition
Dean, David B., Wark, Timothy J., & Sridharan, Sridha (2006) An examination of audio-visual fused HMMs for speaker recognition. In Second Workshop on Multimodal User Authentication, May 11-12, Toulouse, France.
Fused hidden Markov models (FHMMs) have been shown to work well for the task of audio-visual speaker recognition, but only in an output decision-fusion configuration of both the audio- and video-biased versions of the FHMM structure. This paper looks at the performance of the audioand video-biased versions independently, and shows that the audio-biased version is considerably more capable for speaker recognition. Additionally, this paper shows that by taking advantage of the temporal relationship between the acoustic and visual data, the audio-biased FHMM provides better performance at less processing cost than best-performing output decision-fusion of regular HMMs.
Impact and interest:
Citation counts are sourced monthly from and 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 downloads displays 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.
