该处只要描述说话人分割(speaker diarization)问题的一些分类: 根据处理的语音类型 可以分类为:单通道说话人分割、多通道说话人分割。 单通道说话人分割: 从单一麦克风录制的音频中分割说话者。这是最基本和最常见的类型,但在处理重叠语音和噪声时可能面临挑战。 多通道说话人分割:利用多个麦克风(如阵列麦克风)收集的音...
Speaker Diarization,可翻译为声纹分割聚类、说话人分割聚类、说话人日志,解决的问题是“who spoke when”。给定一个包含多人交替说话的语音,声纹分割聚类需要判断每个时间点是谁在说话。声纹分割聚类问题是声纹领域中仅次于声纹识别的第二大课题,其难度远大于声纹识别。单词diarization来自diary。 声纹分割聚类(Speaker...
Methods, systems, and devices are disclosed that include computer programs encoded on computer storage media for speaker dialification. In one aspect, the method comprises the action of receiving audio data corresponding to the utterance. These actions further include actions that determine that the ...

说话人日志(Speaker Diarization,SD)系统的目标是解决“谁在什么时间说话”的说话人识别问题,是一种可以广泛应用于客服、会议等多轮对话场景的语音技术。无监督聚类一直是 Speaker Diarization (说话人日志) 任务中最核心的一环,通过无监督聚类的方法,可以确定一场会议或多人讨论中的全局关键信息,如:说话人数量、说话...
说话人分割(speaker diarization)问题在技术背景上可依据处理的语音类型分为单通道说话人分割与多通道说话人分割。时间处理方式则区分在线与离线说话人分割。根据说话者知识,此类问题又分为开放集说话人分割与封闭集说话人分割。早期研究关注联盟与挑战,随着深度学习的兴起,端到端神经分离技术(End-to-End...
What is speaker diarization? Speaker diarization is a process of separating individual speakers in an audio stream so that, in the automatic speech recognition (ASR) transcript, each speaker's utterances are separated. Each speaker is separated by their unique audio characteristics and their utterances...
说话人日志(Speaker Diarization,SD)旨在自动化识别多人对话中不同说话人的身份和说话时间区域,解决“谁在什么时间说”的问题。在常见的SD系统中,基于特定人语音活动(Target-Speaker Voice Activity Detection,TS-VAD)的方法在近些年取得了较好的性能。传统的TS-VAD系统作为一个二阶段方法,需要依赖一个前置的日志系统(...
Speaker Diarization is the task of segmenting and co-indexing audio recordings by speaker. The way the task is commonly defined, the goal is not to identify known speakers, but to co-index segments that are attributed to the same speaker; in other words, diarization implies finding speaker ...
1. 首先进行语音活动检测(VAD)以分割原始音频。常见工具包括WebRTC等。分割后的音频被切分成等长小片段,并保证片段间存在重叠,通常采用1.5秒长度片段,每次移动0.25秒抽取下一个片段,确保不会错过任何对话部分。2. 接下来,使用SpeechBrain开源的预训练模型进行特征抽取。这些模型能够提供有效的音频...
