Weekly Report:

   1, Distant speech recognition:
    (1) Done: FFT granularity feature-transform verify, same fuzzy phenomenon with fbank;
    (2) Done: Feature-transform re-adapted based on fbank feature, worse than doing adaptation based or original fbank-feats. --With Xuewei
   2, Feature performance Comparison:
    (1) Done: Original fft feature -- worse performance;
    (2) Done: Dynamic information of fbank feature, adding delta and acceleration gets better performance;
   3, Done: JingDong's pay-pattern fst union.

Target of next week:

   1, Continue Distant speech recognition investigation.
