Zhanjiang Song

Research Leader
Beijing, China

I joined Nokia Research Center in Beijing as Senior Research Engineer in May, 2007 and started with working on service-oriented language processing technologies and applications. Since April 2009, I have been leading a research team working on end-to-end service architectures for scalable rich context data processing systems, etc.

Prior to joining Nokia, I had worked for about 1 year as research scientist in Weniwen Inc. (Hong Kong), and more than 5 years as co-founder and R&D VP in d-Ear Technologies (Beijing), both focusing on speech and language processing systems.

I received my B.S. degree in 1994, majoring in Computer Software and M.S. degree in 1997, majoring in Computer Network, both from Nankai University, China. I received my Ph.D degree in 2001, majoring in Speech Recognition and Language Understanding, from Tsinghua University, China.

Professional Activities

 

  • From Jul. to Aug., 2000, I participate in the international research project (in series) "JHU Workshop 2000: Pronunciation Modeling of Mandarin Casual Speech" carried out at Johns Hopkins University, USA (http://www.clsp.jhu.edu/ws2000/groups/mcs)
  • I was a member of "Chinese Speech Interactive Technology Standard Group (CSITSG)" established by the Ministry of Information Industry (MII) of China, and participated in drafting of "Technical Standard for Automatic Voiceprint Recognition (Speaker Recognition)" (http://www.speechstandard.org.cn)

Research Interests

My research interests include: 

  • Speech and language technologies, such as speech recognition, speaker recognition, natural language processing, etc.
  • Software engineering, such as architecture and interface design and implementation, system integration, etc.
  • Computer network and distributed systems, such as distributed computing and data stream mangement system, etc.
