Notes

Designing Speech User Interfaces (2)
Yankelovich & Lai (1998)

Speech synthesis technology:

'Parameterized' - relatively small and fast (low quality)

Concatenative - more complex and resource intensive (higher quality)

Speech recognition technology:

'Speaker-independent' systems (no training, low scope and reliability)

Training-set based (tuned to a particular user)

Discrete word vs continuous utterance recognition

Variety of techniques used:

Fixed-phrase "command and control"
Rule-based grammar systems
Statistical models
Neural-network assistance
