We present a systematic study on multilingual and cross-lingual intent detection from spoken data. The study leverages a new resource put forth in this work, termed MInDS-14, a first training and evaluation resource for the intent detection task with spoken data. It covers 14 intents extracted from a commercial system in the e-banking domain, associated with spoken examples in 14 diverse language varieties. Our key results indicate that combining machine translation models with state-of-the-art multilingual sentence encoders (e.g., LaBSE) can yield strong intent detectors in the majority of target languages covered in MInDS-14, and offer comparative analyses across different axes: e.g., zero-shot versus few-shot learning, translation direction, and impact of speech recognition. We see this work as an important step towards more inclusive development and evaluation of multilingual intent detectors from spoken data, in a much wider spectrum of languages compared to prior work.

本文提出了一种用于多语言和跨语言口语数据意图检测的系统性研究，对该研究所介绍的一个新资源（MInDS-14）进行了利用，证明使用机器翻译模型和最先进的多语言句子编码器相结合能够在大多数MInDS-14所涵盖的目标语言中产生强大的意图检测器，并提供了针对不同维度（如零-shot学习与有限-shot学习、翻译方向、语音识别的影响）的比较分析。我们认为这项工作是在比以往的工作更广泛的语言范围内开发和评估多语意图检测器的重要一步。
