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.
