TUKE MediaEval 2012: Spoken Web Search using DTW and Unsupervised SVM.
Jozef Vavrek, Matúš Pleva, Jozef Juhár · 2012
This working paper provides the basic information about experiments conducted on audio documents within the MediaEval 2012 spoken web search evaluation project. The main purpose of these experiments was to build a robust and language independent system for spoken term detection. Therefore we have proposed query-by-example searching system based on the minimum-cost alignment of DTW algorithm and unsupervised SVM misclassification rate. Results show that our system is liable to variable length of queries with similar spectral characteristics that results in poor detection performance with high number of insertions and misdetections. There were no other resources used during the development.
