Exploiting sequence information for text-dependent Speaker Verification

ICASSP 2017accepted

Model-based approaches to Speaker Verification (SV), such as Joint Factor Analysis (JFA), i-vector and relevance Maximum-a-Posteriori (MAP), have shown to provide state-of-the-art performance for text-dependent systems with fixed phrases. The performance of i-vector and JFA models has been further e…

Intra-class covariance adaptation in PLDA back-ends for speaker verification

ICASSP 2017accepted

Multi-session training conditions are becoming increasingly common in recent benchmark datasets for both text-independent and text-dependent speaker verification. In the state-of-the-art i-vector framework for speaker verification, such conditions are addressed by simple techniques such as averaging…

Deep neural network based posteriors for text-dependent speaker verification

ICASSP 2016accepted

The i-vector and Joint Factor Analysis (JFA) systems for text-dependent speaker verification use sufficient statistics computed from a speech utterance to estimate speaker models. These statistics average the acoustic information over the utterance thereby losing all the sequence information. In thi…

System fusion and speaker linking for longitudinal diarization of TV shows

ICASSP 2016accepted

Performing speaker diarization while uniquely identifying the speakers in a collection of audio recordings is a challenging task. Based on our previous work on speaker diarization and linking, we developed a system for diarizing longitudinal TV show data sets based on the fusion of speaker diarizati…
