Spectral plane investigation for probabilistic features for ASR
feature extraction, TRAP-tandem, time-frequency context
Frequency and time context for two stage TRAP-TANDEM feature extraction for ASR. Splitting input spectrogram into frequency slices.
This paper discuss importance of frequency and time context in two stage TRAP-TANDEM feature extraction. The advantage of splitting input spectrogram into rather narrow frequency slices with long time context was confirmed.
