-A Speech Interface Previous: 2.2 Implementation
This section describes the user interface provided by
Emacspeak when performing common-place computing tasks like
editing and proof-reading, surfing the WWW, reading and
replying to electronic mail and Usenet news. This paper
description suffers from the natural shortcoming of elucidating
in print what is essentially aural.
Here are some features of the spoken feedback that are
common to the different interaction scenarios:
- Speech output is always interruptible. Actions causing
new information to be spoken first interrupt any ongoing
output.
- Emacspeak provides a voice-lock facility that
permits association of syntactic units of text with different
voices. This is a powerful method of conveying structure
succinctly and was first described in [Ram94]. Audio
Formatting is used to aurally set apart different syntactic
units, for example, highlight regions of text.
- Emacspeak uses auditory icons [JSBG86][BGP93][Gav93][BGB88][SMG90] -short snippets of
sounds (under 0.25--0.5 seconds) seconds to cue common events
such as selecting, opening and
closing an object. Used consistently throughout the
interface, these cues speed up user interaction -an
experienced user can often continue to the next task when an
aural cue[+] is heard without waiting for
the spoken confirmation.
