摘要:

我们在ATCO2项目中推出了一个社区平台,用于收集全球范围内的ATC语音。过滤掉看不见的非英语语音是数据处理管道中的主要组件之一。提出的英语语言检测(ELD)系统是基于贝叶斯子空间多项式模型的嵌入。它是在ASR系统的单词混淆网络上训练的。它坚固耐用,易于训练,重量轻。我们实现了0.0439的等错误率(EER),50%的相对减少相比,最先进的声学ELD系统的基础上,在域的情况下,x向量。此外,在看不见的语言(域外)条件下,我们实现了0.1352的EER,与声学ELD相比相对降低了33%。我们计划发布ATCO2项目的评估数据集。

英文摘要:

We launched a community platform for collecting the ATC speech world-wide in the ATCO2 project. Filtering out unseen non-English speech is one of the main components in the data processing pipeline. The proposed English Language Detection (ELD) system is based on the embeddings from Bayesian subspace multinomial model. It is trained on the word confusion network from an ASR system. It is robust, easy to train, and light weighted. We achieved 0.0439 equal-error-rate (EER), a 50% relative reduction as compared to the state-of-the-art acoustic ELD system based on x-vectors, in the in-domain scenario. Further, we achieved an EER of 0.1352, a 33% relative reduction as compared to the acoustic ELD, in the unseen language (out-of-domain) condition. We plan to publish the evaluation dataset from the ATCO2 project.
