hello

i want to asked you about the probability of recognation

i use User parameter(auxiliary parameter: pitch, formants, energy) as prameter acoustique ..and when i run my process of recongnition i have positives scors of recognition

like this:


"*/fa032s32.rec"
0 4600000 deux2 240.497971
.
"*/fa032s33.rec"
0 5200000 cinq5 -384.486908
.
"*/fa032s34.rec"
0 4800000 quatre4 357.861755
.
"*/fa032s35.rec"
0 4600000 cinq5 70.729980

 

i think viterbi return the logarithme of probability and his values coudn't have a positive value because the probabilité is in the range [0,1]

and: log(a)<0 if 0<a<1

 

Note:

when i use the MFCC parameter all score of recognation is negatif
