- Automatic speech recognition
- Speaker diarization («who spoke when?»)
- Addressee detection («who spoke to whom?»)
- Sentence segmentation and disfluency cleanup
- Dialog act tagging
- Named entity extraction
- Extracting distinguishing keyphrases
- Topic segmentation
- Topic identification (optionally with agenda)
- Keyword spotting
- Hot spot detection
- Speaker role detection
- Argument diagramming for meeting structure extraction
- Agreement/disagreement detection
- Extraction of action items and decisions
- Meeting summarization
Other technologies allow meeting participants to interact with a virtual meeting participant for online assistance. These allow participants to (explicitly or implicitly) call up information that is relevant to the meeting, or flag content on-the-fly (such as action items and decisions).
- Situational spoken language understanding (includes semantic parsing, intent determination, and click/object detection)
- Dialog manager
- Addressee detection
Our work builds on ongoing work in Conversational Understanding research, and past work on the ICSI Meeting Recorder and DARPA The CALO Meeting Assistant System projects.
