摘要:

使用端到端模型进行语音翻译(ST)越来越成为ST社区的焦点。这些模型通过直接将声波转换为翻译文本来压缩先前级联的系统。然而,级联模型的优点是包括自动语音识别输出,这对于经常向用户显示翻译和文字记录的各种实用ST系统很有用。为了弥补这一差距,最近的工作表明,在端到端模型产生这两种输出的可行性方面取得了初步进展。然而,所有以前的工作都只是从连续的角度来看待这个问题,留下了这些方法在更具挑战性的流媒体环境中是否有效的不确定性。我们开发了一个端到端的流ST模型的基础上重新翻译的方法和标准的级联方法进行比较。我们还介绍了一种新的推理方法的联合情况下,交错的成绩单和翻译的生成和消除需要使用单独的解码器。我们对一系列捕获准确性、延迟和一致性的指标进行了评估,结果表明,我们的端到端模型在统计上与级联模型相似,但参数数量只有级联模型的一半。我们还发现,这两个系统都能在低延迟的情况下提供强大的翻译质量,在不到一秒的延迟时间内保持99%的连续质量。

英文摘要:

Using end-to-end models for speech translation (ST) has increasingly been the focus of the ST community. These models condense the previously cascaded systems by directly converting sound waves into translated text. However, cascaded models have the advantage of including automatic speech recognition output, useful for a variety of practical ST systems that often display transcripts to the user alongside the translations. To bridge this gap, recent work has shown initial progress into the feasibility for end-to-end models to produce both of these outputs. However, all previous work has only looked at this problem from the consecutive perspective, leaving uncertainty on whether these approaches are effective in the more challenging streaming setting. We develop an end-to-end streaming ST model based on a re-translation approach and compare against standard cascading approaches. We also introduce a novel inference method for the joint case, interleaving both transcript and translation in generation and removing the need to use separate decoders. Our evaluation across a range of metrics capturing accuracy, latency, and consistency shows that our end-to-end models are statistically similar to cascading models, while having half the number of parameters. We also find that both systems provide strong translation quality at low latency, keeping 99% of consecutive quality at a lag of just under a second.
