  1. Speech Technology Research at ICSI Arlo Faria

  2. ICSI • Independent non-profit research institute • Groups: • Algorithms • Architecture • Artificial Intelligence • Networking & Security • Speech • Vision • Open House: 1947 Center Street, 6th floor

  3. The Speech Group • Group leader: Steven Wegmann • Faculty advisor: Prof. Nelson Morgan • Research staff: Jordan Cohen, Dan Ellis, Jim Hieronymus, Adam Janin, Nikki Mirghafori, Roberto Pieraccini, Liz Shriberg, Andreas Stolcke, Chuck Wooters • Post-docs: Howard Lei, HariParthasarathi • Ph.Dstudents: Shuo-Yiin Chang, Arlo Faria, Mary Knox, SumanRavuri, TJ Tsai, OriolVinyals • Visitors:HaiDo, KorbinianRiedhammer, MircoRavanelli

  4. Research areas • Speech recognition • also: keyword search • Speaker recognition • ID, verification • Multimedia processing • e.g. Web videos

  5. Speech Recognition • Diagnosing flawed HMM assumptions • Acoustic features for noisy data • Revisiting “deep” neural networks • Portability to low-resource languages

  6. Speaker Recognition • Robustness • to noise (AFRL) • to signal degradation (DARPA) • Speaker Diarization (ParLab)

  7. Other research areas • Speech activity detection • Language identification • Conversational, dialog systems • Models based on measured brain activity • auditory cortex of ferrets (UCLA) • neurosurgery patients (UCSF)

  8. Scientific Goals • Robust acoustic processing • Better understanding of principles • Significant (non-incremental) progress • http://www.icsi.berkeley.edu
