Abstract
Embodiments of the present invention disclose a method, system, and computer program product for speech summarization. A computer receives audio and video components from a video conference. The computer determines which participant is speaking based on comparing images of the participants with template images of speaking and non-speaking faces. The computer determines the voiceprint of the speaking participant by applying a Hidden Markov Model to a brief recording of the voice waveform of the participant and associates the determined voiceprint with the face of the speaking participant. The computer recognizes and transcribes the content of statements made by the speaker, determines the key points, and displays them over the face of the participant in the video conference.
