基于关系网络的在线Speaker Diarization

Online Speaker Diarization with Relation Network

Xiang Li, Yucheng Zhao, Chong Luo, Wenjun Zeng

摘要:

本文提出了一个基于关系网络的在线说话人日志系统RenoSD。与由多个独立优化的模块组成的传统diarization系统不同,RenoSD使用单个深度神经网络实现语音活动检测(VAD),嵌入提取和说话人身份关联。RenoSD最显著的特点是采用了一种元学习策略进行说话人身份联想。特别地,关系网络学习以数据驱动的方式学习深度距离度量,并且它可以通过简单的前向传递来确定两个给定的片段是否属于同一个说话者。因此,RenoSD可以以低延迟的在线方式执行。在AMI和CALLHOME数据集上的实验结果表明,所提出的RenoSD系统在最先进的x向量基线上实现了一致的改进。与现有的在线日志系统UIS-RNN相比,RenoSD在使用更少的训练数据和更低的时间复杂度的情况下实现了更好的性能。

英文摘要:

In this paper, we propose an online speaker diarization system based on Relation Network, named RenoSD. Unlike conventional diariztion systems which consist of several independently-optimized modules, RenoSD implements voice-activity-detection (VAD), embedding extraction, and speaker identity association using a single deep neural network. The most striking feature of RenoSD is that it adopts a meta-learning strategy for speaker identity association. In particular, the relation network learns to learn a deep distance metric in a data-driven way and it can determine through a simple forward pass whether two given segments belong to the same speaker. As such, RenoSD can be performed in an online manner with low latency. Experimental results on AMI and CALLHOME datasets show that the proposed RenoSD system achieves consistent improvements over the state-of-the-art x-vector baseline. Compared with an existing online diarization system named UIS-RNN, RenoSD achieves a better performance using much fewer training data and at a lower time complexity.
