Spherical Coordinate Geometry
This last feature could prove interesting if two computers, both
equipped with AI, speech synthesis, and speech recognition, got into an
argument. One machine might be programmed as a Republican and the
other as a Democrat; the engineer could bring up the subject of taxes and
let the two machines argue.
For further information
The best source of up-to-date information on speech synthesis is a good
college library. A search on the phrases “speech synthesis” and “voice
synthesis” can be conducted on the Web using Google (www.google.com)
or a similar search engine. Related entries include: BANDWIDTH, CONTEXT, DATA
CONVERSION, DIGITAL SIGNAL PROCESSING, MESSAGE PASSING, OPTICAL CHARACTER RECOGNITION,
PROSODIC FEATURES, SOUND TRANSDUCER, SPEECH RECOGNITION, and SYNTAX.
SPHERICAL COORDINATE GEOMETRY
Spherical coordinate geometry is a scheme for guiding a robot arm in three
dimensions. A spherical coordinate system is something like the polar
system, but with two angles instead of one. In addition to the two angles,
there is a radius coordinate.
One angle, call it x, is measured counterclockwise from the reference
axis. The value of x can range from 0° to 360°. You might think of x as

r
