ISD
SS
Say sentence number sentence_n of the currently selected vocabulary. sentence_n is 1-byte long.
The VoiceDSP processor state changes to SYNTHESIS.
Say Sentence sentence_n
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.
Example
SS 00
Byte sequence:
SSM
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:
Set Speakerphone Mode mode
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.
