摘要:

语音翻译中的常规范例以生成转录本的语音识别步骤开始,随后是以自动转录本作为输入的翻译步骤。为了解决这种范式的各种缺点,最近的工作探索了端到端可训练的直接模型,这些模型无需转录即可翻译。然而,在实际应用中,成绩单可能是不可或缺的输出,这些应用通常将成绩单与翻译一起显示给用户。我们明确了这一共同要求,并探讨了共同转录和翻译语音的任务。虽然转录和翻译的高准确性是至关重要的,但即使是高度准确的系统也可能遭受两种输出之间的不一致,这会降低用户体验。我们介绍了一种方法来评估一致性和比较几种建模方法,包括传统的级联方法和端到端模型。我们发现,直接模型不适合联合转录/翻译任务,但端到端的模型,具有耦合推理过程能够实现强一致性。我们进一步介绍了简单的技术,直接优化的一致性,并分析一致性,转录准确性和翻译准确性之间的权衡。

英文摘要:

The conventional paradigm in speech translation starts with a speech recognition step to generate transcripts, followed by a translation step with the automatic transcripts as input. To address various shortcomings of this paradigm, recent work explores end-to-end trainable direct models that translate without transcribing. However, transcripts can be an indispensable output in practical applications, which often display transcripts alongside the translations to users. We make this common requirement explicit and explore the task of jointly transcribing and translating speech. While high accuracy of transcript and translation are crucial, even highly accurate systems can suffer from inconsistencies between both outputs that degrade the user experience. We introduce a methodology to evaluate consistency and compare several modeling approaches, including the traditional cascaded approach and end-to-end models. We find that direct models are poorly suited to the joint transcription/translation task, but that end-to-end models that feature a coupled inference procedure are able to achieve strong consistency. We further introduce simple techniques for directly optimizing for consistency, and analyze the resulting trade-offs between consistency, transcription accuracy, and translation accuracy.
