  1. SPEECH RECOGNITION

  2. "I enjoy working with people."--HAL 9000“Open the pod bay doors, Hal."--Dave Bowman (Keir Dullea)"I'm sorry, Dave. I'm afraid I can't do that."--HAL"What's the problem?"--Dave"I think you know what the problem is just as much as I do."--HAL"What are you talking about, Hal?"--Dave"This mission is too important for me to allow you to jeopardize it."--HAL

  3. A BRIEF INTRODUCTION

  4. WHAT IS SPEECH RECOGNITION? • SPEECH • FEATURES USED IN RECOGNITION

  5. SPEECH RECOGNITION SYSTEMS CLASSIFICATION

  6. Classification continued.. Isolated Word Recognition Continuous speech Recognition

  7. Classification continued… • Speaker dependent • Speaker independent • Connected word • Conversational

  8. Basic phases of SR • Training Phase • Recognizing phase

  9. Phases

  10. How do they work? • Audio Recording/Detection • PreFiltering • Framing/Windowing • Additional filtering • Matching

  11. Applications/Uses • Dictation • Command • Telephony • Medical • Embedded systems • Car Industry • Education
