摘要:

用户研究表明,减少我们的同步演讲翻译系统的延迟应该是最重要的目标。因此,我们研究了几种技术来减少自动语音识别和语音翻译模块这两个组件的延迟。由于通常使用的提交延迟不适合我们的连续流解码情况,我们专注于字延迟。我们使用它来分析我们当前系统的性能,并确定改进的机会。为了最大限度地减少延迟,我们结合了运行解码与流解码时用于识别稳定部分假设的技术和用于动态输出更新的协议,该协议允许修改转录的最新部分。这种组合减少了字级的延迟,其中字是最终的,将来不会再次更新,从18.1秒到1.1秒,而不会牺牲字错误率方面的性能。

英文摘要:

User studies have shown that reducing the latency of our simultaneous lecture translation system should be the most important goal. We therefore have worked on several techniques for reducing the latency for both components, the automatic speech recognition and the speech translation module. Since the commonly used commitment latency is not appropriate in our case of continuous stream decoding, we focused on word latency. We used it to analyze the performance of our current system and to identify opportunities for improvements. In order to minimize the latency we combined run-on decoding with a technique for identifying stable partial hypotheses when stream decoding and a protocol for dynamic output update that allows to revise the most recent parts of the transcription. This combination reduces the latency at word level, where the words are final and will never be updated again in the future, from 18.1s to 1.1s without sacrificing performance in terms of word error rate.
