SV
Set Vocabulary Typetype id
Selects the vocabulary table to be used for voice synthesis.
The vocabulary type is set according to the 1-byte type pa-
rameter:
0: For compatibility only
1: External vocabulary in ROM
2: External vocabulary in Serial Flash
All others: Reserved
The host is responsible to select the current vocabulary with
SV before using an SO, SW, SS or SAS command.
Each external vocabulary table has a uniqueid which is part
of the vocabulary internal header (See theIVS User’s Manu-
al for more details). If type is 1 or 2, the CompactSPEECH
searches for the one byte id parameter in each vocabulary
table header until a match is found.
If the id parameter does not point to a valid IVS vocabulary
ERRDPARAM is set in the error word.
Example
SV 02 03
Byte sequence:
Microcontroller
20 02 03
CompactSPEECH 20 02 03
Description:
Select the vocabulary with vocabulary-id
3, which resides on Serial Flash, as the
current vocabulary.
SW
Say Wordsn word
1
. . . word
n
Plays n words, indexed by word
1
to word
n
. On completion,
the EVDNORMALDEND bit in the status word is set, and
the MWRQST signal goes low.
If one of the words is not defined in the current vocabulary,
or if it is an IVS control or option code, ERRDPARAM is set
in the error word.
If the current vocabulary is undefined, ERRDINVALID is re-
ported.
Example
SW 02 00 00
Byte sequence:
Microcontroller
21 02 00 00
CompactSPEECH 21 02 00 00
Description:
Announce the first word, in the word table
of the currently selected vocabulary,
twice.
TUNE
Tuneindex parameterDvalue
Sets the value of the tunable parameter identified by index
(one byte) to the 2-byte value,parameterDvalue. This com-
mand may be used to tune the DSP algorithms to a specific
Data Access Arrangement (DAA) interface, or to change
other parameters. If you do not use TUNE, the Compact-
SPEECH uses default values.
If index does not point to a valid tunable parameter,
ERRDPARAM is set in the error word.
Note:
The tunable parameters are assigned with their default values on ap-
plication of power. The INIT command does not affect these parame-
ters.
Table 2-2 describes the tunable parameters, their index
numbers and their default values.
