Set Vocabulary Type

type 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 unique

id which is part

of the vocabulary internal header (See the

IVS 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

ERR

PARAM 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

Say Words

n word1

wordn

Plays

n words indexed by word1 to wordn On completion

the EV

NORMAL

END 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 ERR

PARAM is set

in the error word

If the current vocabulary is undefined ERR

INVALID 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

Tune

index parameter

value

Sets the value of the tunable parameter identified by

index

(one byte) to the 2-byte value

parameter

value 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

index does not point to a valid tunable parameter

ERR

PARAM 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
