Control and Option Codes
The list of word indices alone cannot provide the
entire range of sentences that the VoiceDSP pro-
cessor is able to synthesize. IVS control and option
codes send special instructions to control the
speech synthesis algorithm’s behavior in the pro-
cessor.
For example, if the sentence should announce
the time of day, the VoiceDSP processor should
be able to substitute the current day and time in
the sentence. These control words do not repre-
sent recorded words, rather they instruct the pro-
cessor to take special actions.
THE IVS TOOL
The IVS tool includes two utilities:
The tools help create vocabularies for the VoiceD-
SP processor. They take you from designing the vo-
cabulary

vocabulary sentences, to recording the vocabu-
lary words.
IVS Compiler
The IVS compiler runs on MS-DOS (version 5.0 or
later) and enables you to insert your own vocabu-
lary, (i.e., basic words and data used to create
numbers and sentences, as directories and files in
MS-DOS). The IVS compiler then outputs a binary
file containing that vocabulary. In turn, this infor-
mation can be burned into an EPROM or Flash
memory to be used by the VoiceDSP software.
IVS Voice Compression
Each IVS vocabulary can be compiled with either
the 4.7 Kbit/s, the 6.7 Kbit/s or the 8.7 Kbit/s voice
compression algorithm, or in PCM format. Define
the bit rate before compilation. The VoiceDSP pro-
cessor automatically selects the required voice
decompression algorithm when the SV com-
mand chooses the active vocabulary.
