In this talk we present the meeting recognition and understanding system for the CALO Meeting Assistant (CALO-MA) project. CALO-MA is an automatic agent that assists meeting participants, and is part of the larger CALO effort to build a ``Cognitive Assistant that Learns and Organizes'' under DARPA's ``Perceptive Assistant that Learns'' (PAL) program. The focus of CALO in general is ``learning in the wild'', or continuous improvement of the system's abilities as a result of system use.

In this talk, we present the research challenges for the CALO-MA meeting recognition and understanding system. The goal of the system is to provide real-time and offline automatic recognition of utterances, sentence boundaries and dialog act tags, action items, decisions, and automatic summaries. More specifically, we will focus on efforts on extending the SRI Decipher ASR system to handle streaming speech, exploiting previous meetings speech to improve language models in an unsupervised fashion, adapting the models for ASR, dialog act segmentation and tagging to the CALO domain, and experiments on using prosodic information for action item description and agreement/disagreement detection.

This is joint work of SRI, ICSI, and CSLI.
