Hi sandrot,
this is highly dependant on the ambient noise.
you can set the microphone gain from as follow (see a config.mca file) :
| Code: | ;--------------------- Microphone Gain Definitions ----------------------------
;
; Select one distance by equating symbol to MIC_DISTANCE
HEADSET .EQU 1 ; Mic is an inch or so from the mouth
; amp gain is reduced, agc initially low
ARMS_LENGTH .EQU 2 ; Mic is at normal nearby operation
; max gain, medium agc
FAR_MIC .EQU 3 ; Mic is distant, e.g., 10 feet away
; max gain and initial agc |
according to my experiment, you will need an headset in a noisy environment, but you can expect to have good results up to 2 or 3 meters in a quiet room with max gain.
I recommend to use an headset for the training phase.
