摘要:

与语音接口交互以查询问答(QA)系统正变得越来越流行。通常,QA系统依赖于段落检索来选择候选上下文,并依赖于阅读理解来提取最终答案。虽然已经有一些注意力,以提高阅读理解部分的QA系统对错误的自动语音识别(ASR)模型介绍,段落检索部分仍然是未开发的。然而,这样的错误会影响段落检索的性能,导致较差的端到端性能。为了解决这一差距,我们增加了两个现有的大规模通道排名和开放域QA数据集与合成ASR噪声和研究词汇和密集检索器对ASR噪声的问题的鲁棒性。此外,我们还研究了数据增强技术在不同领域的可推广性;每个领域都是不同的语言方言或口音。最后,我们创建了一个新的数据集,其中包含人类用户提出的问题,并使用它们的透明度来表明,当处理自然ASR噪声而不是合成ASR噪声时,检索性能会进一步降低。

英文摘要:

Interacting with a speech interface to query a Question Answering (QA) system is becoming increasingly popular. Typically, QA systems rely on passage retrieval to select candidate contexts and reading comprehension to extract the final answer. While there has been some attention to improving the reading comprehension part of QA systems against errors that automatic speech recognition (ASR) models introduce, the passage retrieval part remains unexplored. However, such errors can affect the performance of passage retrieval, leading to inferior end-to-end performance. To address this gap, we augment two existing large-scale passage ranking and open domain QA datasets with synthetic ASR noise and study the robustness of lexical and dense retrievers against questions with ASR noise. Furthermore, we study the generalizability of data augmentation techniques across different domains; with each domain being a different language dialect or accent. Finally, we create a new dataset with questions voiced by human users and use their transcriptions to show that the retrieval performance can further degrade when dealing with natural ASR noise instead of synthetic ASR noise.
