Speech and Image Processing for Human/Machine Communication

Transmission advances over the next few years will provide pervasive switched digital capacity. Adundant bandwidth will facilitate multimedia communication among humans, and between humans and machines. A challenge lies in utilizing the capacity thoughtfully, and in matching information formats to the sensory capabilities of humans. This discussion draws a perspective on techniques for efficient coding of information signals (especially speech, picture and wideband audio), and on evolving machine capabilities for voice synthesis and recognition.
