After their introduction to robust speech recognition, power normalized cepstral coefficient (PNCC) features were successfully adopted to other tasks, including speaker verification. However, as a feature extractor with long-term operations on the power spectrogram, its temporal processing and amplitude scaling steps dedicated on environmental compensation may be redundant. Further, they might suppress intrinsic speaker variations that are useful for speaker verification based on deep neural…

A Comparative Re-Assessment of Feature Extractors for Deep Speaker Embeddings
TLDR
This work provides extensive re-assessment of 14 feature extractors on VoxCeleb and SITW datasets to reveal that features equipped with techniques such as spectral centroids, group delay function, and integrated noise suppression provide promising alternatives to MFCCs for deep speaker embeddings extraction.

TLDR
Experimental results demonstrate that PNCC processing provides substantial improvements in recognition accuracy compared to MFCC and PLP processing for speech in the presence of various types of additive noise and in reverberant environments, with only slightly greater computational cost than conventional MFCC processing.
Attentive Statistics Pooling for Deep Speaker Embedding
TLDR
Attention statistics pooling for deep speaker embedding in text-independent speaker verification uses an attention mechanism to give different weights to different frames and generates not only weighted means but also weighted standard deviations, which can capture long-term variations in speaker characteristics more effectively.

TLDR
Results that suggest adapting from a model trained with Mandarin can improve accuracy for English speaker recognition are presented, and it is suggested that Deep Speaker outperforms a DNN-based i-vector baseline.
Speaker Recognition for Multi-speaker Conversations Using X-vectors
TLDR
It is found that diarization substantially reduces error rate when there are multiple speakers, while maintaining excellent performance on single-speaker recordings.
A study on data augmentation of reverberant speech for robust speech recognition
TLDR
It is found that the performance gap between using simulated and real RIRs can be eliminated when point-source noises are added, and the trained acoustic models not only perform well in the distant- talking scenario but also provide better results in the close-talking scenario.
