SS
Say Sentence sentence_n
Say sentence number sentence_n of the currently selected vocabulary. sentence_n is 1-byte long.
The VoiceDSP processor state changes to SYNTHESIS.
If the sentence has an argument, 0 is passed as the value for this argument.
When playing has been completed, the VoiceDSP processor sets the EV_NORMAL_END bit in the status
word, and activates the MWRQST signal. The state then changes to IDLE.
If sentence_n is not defined in the current vocabulary, ERR_PARAM is set in the error word.
If the current vocabulary is undefined, ERR_INVALID is reported.

Set Speakerphone Mode mode
Sets the speakerphone to the mode mode of operation. The command is valid when the VoiceDSP
processor is in IDLE state. mode can be one of:
0
OFF
Deactivate the speakerphone, and return the VoiceDSP processor to
normal operation mode.
1
ON
Put the VoiceDSP processor in speakerphone mode and activate speak-
erphone in full-duplex mode i.e., with full cancellation of both the acous-
tic and the electrical echoes. Tone detectors are not active. Gains in the
Send and Receive paths are set by the relevant tunable parameters.
2
TRANSPARENT Activate the speakerphone with no echo cancellation (this mode is used
for system tuning).
3
MUTE
Activate the speakerphone, while generating silence to the line. The
near-end-listener can hear the far-end-speaker, but not vice versa. Tone
detectors are not active.
4
LISTEN
The line is audible on the speaker. Tone detectors are active. This mode
is used for call generation.
5
Reserved.
6
RESTART
Restart the current speakerphone mode. This mode differs from ON; it
does not require full initialization of the speakerphone. It should be used
to resume the speakerphone operation after HOLD mode or to adjust to
an environment change (e.g., parallel pickup).
7
HOLD
Stop the codec interrupts. Neither side can hear each other.
See “Full-duplex Speakerphone” on page 2-14 for more details.
