In this task, you will be presented with a context from an academic paper and a question separated with a
. You have to answer the question based on the context.
Q: Input features are 40 mel-scaled log filterbank enegries (FBanks) computed every 10 ms with 25 ms window, concatenated with deltas and delta-deltas (120 features in vector). We also tried to use spectrogram and experimented with different normalization techniques.
Question: What features do they experiment with?
