Research Field -- Audio Content Analysis

 

 

 

  Audio content analysis is a technology which analyzes and mines information implied in audio and video signals. Related fields include automatic speech recognition(ASR), audio signal processing, natural language processing(NLP), etc. The typical application scenarios include:

  • Contact Center: processing automatically recorded audio data, enhancing the efficiency of quality control, improving the quality of customer service and mining business intelligence from customer calls.

  • Multimedia Information Processing: efficiently searching and browsing massive audio and video data from Internet and media institutions.

  • Law and Finance affairs: efficiently processing audio and video data related to lawsuits to ensure legitimacy of commercial activities.

  • National Security: preventing terrorist attacks and other threats to national security

   The concerns of our lab are the application of audio content analysis in multimedia information processing and national security.
