140707 - Zhiyong Zhang
From cslt Wiki
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.
