为了庆祝澳门科技大学成立17周年，资讯科技学院于2017年3月28日在A座A201室举办学术研讨会，幷特别邀请了美国Honeywell Automated Control Solutions Labs的张晓明博士担任本次研讨会的演讲嘉宾。他以《From VAD to Siri: A 30-year Journey of Human Speech Understanding Technology R&D at the Bell Systems》为题进行了演讲。资讯科技学张渡院长以及师生共20余人出席了研讨会。
演讲摘要:
Human speech has been the heart and soul of the American telecom industry for over 140 years. Alexander Graham Bell filed his first and most famous patent for the telephone in 1874. Some 70 years later in 1944, the Bell Labs developed a device capable of recognizing human speech in its most primitive form in real time. Since then, Automatic Speech Recognition (ASR) technology has inspired many STEM graduates to pursue its practical applications in the telecomm industry and beyond over the past 7 decades. It is in this context that the presenter will first give a historical review of some of major research activities in areas of human speech understanding technology at the Bell Systems over the last 30 years (1984-2014). Then, he discusses a recent research project in area of natural language understanding technology in context of voice search engine for TV content by exploring mutual information (MI) techniques using a structured text corpus derived from actual TV electronic programming guide (EPG).
张晓明博士简介:
Dr. Chang began his research career in the Bell systems in 1986 and span over the next 25 years, starting as a member of technical staff (MTS) at Nynex (the Baby Bell in the northeast region) in 1986 and then moved to Southwestern Bell in 1993 as a Senior MTS and subsequently as Principal MTS and Lead MTS at SBC Communications. After the historical merger of SBC Communications and the legacy AT&T from 2006 and 2013, he was a Lead MTS at the new AT&T Labs in Austin, TX. Currently, he is Sr. Voice Architect at Honeywell Automated Control Solutions (ASC) Labs in Minneapolis, MN. He received his BS degree in CS from Nanjing University in 1977. He enrolled in the first graduate program at the Chinese Academy of Science in Beijing from 1978 and 1980. He came to the U.S. in 1981 and received his doctor of science degree in CS from the Engineering School at Washington University in St. Louis in May 1987. Dr. Chang has published over 20 papers and holds 26 US patents. Dr. Chang is a Senior IEEE member.
