The speech input vector can be read from HTK parameter file, or Julius extracts the parameters directly from input speech. Julius supports extraction of only MFCC format of fixed dimension. More precisely, only parameter type of MFCC_{0|E}_D[_Z][_N] with {25|26} dimensions is supported.
When recognition, the parameter types of both acoustic model and input parameter should be the same. Please note that only the parameter type is checked, and other parameters such as source sampling rate, frame shift length and window sizes will not be checked.
