Speaker diarization: A perspective on challenges and opportunities from theory to practice

Kenneth Church, Weizhong Zhu, Josef Vopicka, Jason W. Pelecanos, Dimitrios Dimitriadis, Petr Fousek

ICASSP 2017accepted

This paper discusses some challenges and opportunities in developing a speaker diarization system for operation on real world call center telephony data. We contrast some of the differences between a standard data set akin to NIST evaluations and those found in call centers. In exploring these diffe…

Evaluating Deep Scattering Spectra with deep neural networks on large scale spontaneous speech task

Petr Fousek, Pierre L. Dognin, Vaibhava Goel

ICASSP 2015accepted

Deep Scattering Network features introduced for image processing have recently proved useful in speech recognition as an alternative to log-mel features for Deep Neural Network (DNN) acoustic models. Scattering features use wavelet decomposition directly producing log-frequency spectrograms which ar…
