F2xx Bit
Values
After power-on, the MSM6679A-110's mode corresponds to that after issuing a F20C command.
This mode may NOT be the optimum condition for most situations, so the user is advised to carefully understand
the desired condition and develop a suitable command for the application at hand.
In addition, ensure that unwanted bits do not get set or reset when attempting to set individual conditions. The
conditions selected are based on the XXh values associated with the last F2 command issued.
Background Noise Initialization. When set to 1, the MSM6679A-
110 starts a 500-ms background noise initialization. When set to
0, the MSM6679A-110 does not perform background noise
initialization.
The MSM6679A-110 requires this command prior to recognition
for noise vector subtraction during the utterance sampling period.
Use the background initialization command whenever there is a
change in the background noise level. For example, sample the
noise signature in a vehicle at rest and moving at 35 MPH with its
windows rolled down. The quality of a phone line connection can
also vary from call to call.
The host MCU must implement a strategy as to when to issue a
background initialization command. In a vehicle, the host MCU
could monitor the vehicle speed, fan speed, radio volume, etc.
Alternatively, the host MCU could issue this command each time a
new recognition session starts or a new line connection is
established. However, the 0.5-sec sample period could degrade
system responsiveness if used too frequently. A zero in this bit
location during the F2XXh command will not cause an
initialization. The F505h command causes the same initialization
sequence.
Wait for Recognition Command/Auto Restart SI Recognition.
When set to 1, the MSM6679A-110 waits for a recognition
command after each response. When set to 0, the MSM6679A-
110 auto-restarts SI recogni-tion after each response.
This bit should be set to 1 when an action is to be taken
immediately after an utterance. Auto-restart recognition is the
desired mode during digit string recognition, automated tape
testing of digits, or in demonstrations where continuous
recognition is desired.
