关节特征本质上是声信号失真的不变,并且已成功地纳入了为正常语音设计的自动语音识别(ASR)系统。它们在非典型任务领域(例如老年人和跨语言的言语无序)的实际应用通常受到从目标扬声器收集此类专家数据的困难。本文介绍了一种跨域和跨语性A2A反演方法,该方法利用了A2A模型中24小时TAL Corpus的平行音频,视觉和超声舌成像(UTI)数据,然后进行交叉训练和交叉训练。语言适用于两种语言的三个数据集:英语dementiabank pitt和antonese JCCOCC MOCA老年演讲Corpora;以及英语Torgo违反语音数据,以产生基于UTI的发音特征。 Experiments conducted on three tasks suggested incorporating the generated articulatory features consistently outperformed the baseline hybrid TDNN and Conformer based end-to-end systems constructed using acoustic features only by statistically significant word error rate or character error rate reductions up to 2.64%, 1.92% and数据增强和说话者适应后,绝对4.17%,7.89%和13.28%相对1.21%。
