Speech Interfaces

Unlike GUI design, speech interface design is still in its infancy. As we gain more experience our understanding will improve.

Speech Interface Guidelines

A set of guidelines that distill current practice in building speech interfaces at Carnegie Mellon is available (also as a PDF file). These guidelines have been found effective for interfaces that are part of desktop computers, this being what we are the most familiar with. They may be less appropriate in other contexts, such as telephone-based interfaces; on the other hand, they catalogue a variety of common-sense features which should be useful across various implementations.

Speech Agents

This project explores speech-only interfaces for devices for which traditional interface elements (keyboards, displays) are lacking but which nevertheless are meant to be used for complex tasks. Wearable computers are an important class of such devices.

Since such devices lack GUIs, the interfaces begin to look less like traditional interfaces and begin to assume some of the characteristics of human interlocutors in their ability to maintain a communication channel with a human user. A short working paper on this topic is available.
