Put the VoiceDSP processor into Speakerphone mode, and set the speakerphone to full-duplex mode.
SV
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 parameter:
0
For compatibility only.
1
External vocabulary in ROM.
2
External vocabulary in Flash.
3-7 Reserved.
The host is responsible for selecting the current vocabulary, with SV command, before using an SAS,
SO, SS or SW command. Each external vocabulary table has a unique id which is part of the vocabu-
lary internal header (See the IVS User’s Guide for more details). If type is 1 or 2, the VoiceDSP processor
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

Select the vocabulary with vocabulary-id 3, which resides on a Flash, as the current
vocabulary.
SW
Say Words n word₁. . . word_n
Plays n words, indexed by word₁ to word_n. The VoiceDSP processor state changes to SYNTHESIS.
On completion, the EV_NORMAL_END bit in the status word is set, and the MWRQST signal goes low.
The state then changes to IDLE.
If one of the words is not defined in the current vocabulary, or if it is an IVS control or option code, or
if n > 8, ERR_PARAM is reported.
