I-vectors in the context of phonetically-constrained short utterances for speaker verification
2012 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)
Short speech duration remains a critical factor of performance degradation when deploying a speaker verification system. To overcome this difficulty, a large number of commercial applications impose the use of fixed pass-phrases. In this context, we show that the performance of the popular i-vector approach can be greatly improved by taking advantage of the phonetic information that they convey. Moreover, as i-vectors require a conditioning process to reach high accuracy, we show that furtherdoi:10.1109/icassp.2012.6288986 dblp:conf/icassp/LarcherBLMLB12 fatcat:qkkwi46wr5hd7lkfc56dxw56gq
