On the enhancement of speaker identification accuracy using weighted bilateral scoring
Malegaonkar, A.; Ariyaeeinia, A.; Sivakumaran, P.; Fortuna, J. (2008-10-16)This paper presents investigations into an effective bilateral scoring method in open-set speaker identification. The approach is based on the fact that two different speakers usually are not reciprocal. A difficulty in ... -
On the use of decoupled and adapted Gaussian mixture models for open-set speaker identification
Fortuna, J.; Malegaonkar, A.; Ariyaeeinia, A.; Sivakumaran, P. (Office for Official Publications of the European Communities, 2005)This paper presents a comparative analysis of the performance of decoupled and adapted Gaussian mixture models (GMMs) for open-set, text-independent speaker identification (OSTISI). The analysis is based on a set of ... -
Unsupervised Speaker Change Detection using Probabilistic Pattern Matching
Malegaonkar, A.; Ariyaeeinia, A.; Sivakumaran, P.; Fortuna, J. (2006)This letter presents an investigation into the use of a probabilistic pattern matching approach for detecting speaker changes in audio streams. The experiments are conducted using clean speech as well as broadcast news ...
