ConceptBeam: Concept driven target speech extraction

Yasunori Ohishi, Marc Delcroix, Tsubasa Ochiai, Shoko Araki, Daiki Takeuchi, Daisuke Niizumi, Akisato Kimura, Noboru Harada, Kunio Kashino

Using the concepts (semantic content) conveyed by speech and images as a clue, we have developed the first technology in history for extracting speech signals of speakers speaking about a topic or concept of interest in a recording of multiple talkers. This technology can be applied to innovative applications such as listening AIs that focus on a particular topic discussed in a conversation.

NTT Communication Science Laboratories will promote basic research with the aim of building fundamental theories that approach the essence of human beings and information, and creating innovative technologies that will revolutionize society.
