AI总结:

本文提出基于非自回归语言模型的第二遍说话人标签校正系统,用于修正不同说话人句子边界处的词语错误,在TAL和Fisher数据集上降低了WDER,并在Post-ASR挑战赛中显著改善了cpWER。

摘要:

处理对话的语音应用不仅需要识别所说的词语,还需要确定谁在何时说话。将词语分配给说话人的任务通常通过合并两个独立系统的输出来完成,即自动语音识别(ASR)系统和说话人日志(SD)系统。在实际环境中,说话人日志系统可能由于多种因素而出现显著的性能下降,这些因素包括高时间分辨率的均匀分割、不准确的词时间戳、错误的聚类和说话人数目估计,以及背景噪声。因此,自动检测错误并在可能的情况下进行修正是很重要的。我们使用了一个基于非自回归语言模型的第二遍说话人标签校正系统,来修正在不同说话人所说句子边界处的词语错误。我们首先表明,所采用的错误校正方法在两个数据集上降低了词日志错误率(WDER):TAL和Fisher的测试集。此外,我们在Post-ASR说话人标签校正挑战赛中评估了我们的系统,并观察到与基线方法相比,cpWER有显著改善。

英文摘要:

Speech applications dealing with conversations require not only recognizing the spoken words but also determining who spoke when. The task of assigning words to speakers is typically addressed by merging the outputs of two separate systems, namely, an automatic speech recognition (ASR) system and a speaker diarization (SD) system. In practical settings, speaker diarization systems can experience significant degradation in performance due to a variety of factors, including uniform segmentation with a high temporal resolution, inaccurate word timestamps, incorrect clustering and estimation of speaker numbers, as well as background noise. Therefore, it is important to automatically detect errors and make corrections if possible. We used a second-pass speaker tagging correction system based on a non-autoregressive language model to correct mistakes in words placed at the borders of sentences spoken by different speakers. We first show that the employed error correction approach leads to reductions in word diarization error rate (WDER) on two datasets: TAL and test set of Fisher. Additionally, we evaluated our system in the Post-ASR Speaker Tagging Correction challenge and observed significant improvements in cpWER compared to baseline methods.
