The basis vector parameters are 16 LPC coefficient, 16 LPC
coefficient, 16
LPC coefficient,
energy and
energy.
We used only the last 8 (c9-c16) LPC coefficient, the 16 LPC, the 16
LPC and energy coefficients.
The speech signal is windowed at 32[ms] shifted each 10[ms], pre-emphasis 0.95, liftering 16. Cepstral mean subtraction (CMS) is used for channel compensation.
We didn't used any other normalization (i.e handset normalization).
