Radio Shack VoxBox TRS-80 User Manual

1. Introduction
This
manual provides the
serviceman
information
necessary
to repair the
Radio Shack
TRS-80 VOXBOX
Speech Recognition
peripheral.
The
hardware
involved in
the device is
fairly simple;
most of the complex
task of
speech recognition
is
accomplished
by the
TRS-80 computer,
which
executes a software
algorithm
on the raw
data
provided
by
the
speech recognition
hardware. The
hardware itself
simply
extracts
four bits of
information
from the
speech waveform
and presents it
to the computer.
The
recognition
program
samples this data
approximately
every 10
ms.
In
addition,
two BASIC
test programs
are available
to help
debug the
board. The
first
program tests the
board by training
and recognizing
the ten digits
zero
through nine. The
second program plots the
information
gathered
by
the
board
on the
video monitor
where it may
be compared
to known
patterns
to help isolate
the
problem.
