同声传译结合了机器翻译（MT）、自动语音识别（ASR）和文本语音合成（TTS）等人工智能技术，在国际会议、商务谈判、新闻发言、法律诉讼和医学交流等众多场景都有广泛的应用，已发展成为一个前沿的研究领域。作为一个新兴的跨学科领域，同声传译未来将面临更多挑战。
Simultaneous translation, which performs translation concurrently with the source speech, is widely useful in many scenarios such as international conferences, business negotiations, press releases, legal proceedings and medical communications. It combines the AI technologies of machine translation (MT), automatic speech recognition (ASR) and text-to-speech synthesis (TTS),and is becoming a cutting-edge research field. As an emerging interdisciplinary field, Simultaneous translation will face more challenges in the future.
为了促进同声传译的发展，在ACL2020上，百度联合Google、Facebook、宾夕法尼亚大学、清华大学等顶尖机构和高校成功地举办了第一届同声传译研讨会，共邀请到6位主讲嘉宾，吸引了94名注册参与者。研讨会上同期发布的汉英同声翻译竞赛任务，共吸引了227名参赛者。该竞赛任务为参赛者提供了开放数据集：百度语音翻译语料库（BSTC），涵盖了信息技术、经济、文化、生物、艺术等多个领域的专题演讲。
In order to promote the development of simultaneous interpretation, Baidu, together with Google, Facebook, University of Pennsylvania, Tsinghua University and other top institutions and universities, successfully held the first automatic simultaneous translation workshop at ACL2020, which invited 6 keynote speakers and attracted 94 registered participants. A total of 227 participants participated in the competition. The competition task provides the participants with an open data set: Baidu speech translation corpus (BSTC), which covers the thematic speeches in the fields of information technology, economy, culture, biology, art and so on.
为了进一步推动机器同传技术的发展，在NAACL 2021上，将继续举办第二届同声传译研讨会，汇集了机器翻译、语音处理和人类口译领域的众多研究人员和实践者，共同讨论同声传译的最新进展和当下面临的突出挑战，包括：
To further promote the development of simultaneous translation, we will host the 2nd automatic simultaneous translation workshop at NAACL2021, brings together many researchers and practitioners in the field of machine translation, speech processing, and human interpretation to discuss the latest progresses and current challenges, including:
· 同声传译范式： 在传统流水线（ASR-MT-TTS）或端到端（语音语音）框架下，如何构建高质量、低延迟的同传系统；
· 数据资源： 如何高效运用训练同声翻译系统的大型高质量语料库；
· 评价方法： 如何评价翻译质量和如何选取时间延迟指标；
· 计算机辅助口译（CAI）： 如何尽快提高人工翻译的效率和质量。
· Simultaneous translation paradigms: traditional pipeline (ASR-MT-TTS) or end-to-end (speech-speech);
· Data resources: large and high-quality corpora for training simultaneous translation systems.
· Evaluation methods: metrics to evaluate the translation quality and time latency;
· Computer Aided Interpretation (CAI): improve the efficiency and quality of human interpreters.
