Parametrization

The basis vector parameters are 16 LPC coefficient, 16 tex2html_wrap_inline154LPC coefficient, 16 tex2html_wrap_inline156LPC coefficient, tex2html_wrap_inline154energy and tex2html_wrap_inline156energy.

We used only the last 8 (c9-c16) LPC coefficient, the 16 tex2html_wrap_inline154LPC, the 16 tex2html_wrap_inline156LPC 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).
