ACOUSTIC MODEL ADAPTATION FROM RAW WAVEFORMS WITH SINCNET
Table 2: Results (% WER) on AMI with various filter initialisation.
['[BOLD] Initialisation', '[BOLD] Eval', '[BOLD] Dev']
The various initialisation schemes produce quite similar WERs, but, perhaps surprisingly, the Mel-initialisation performs least well. The differences are, however, less than 2% relative. Overall these numbers are roughly 5 percentage points worse than those produced with cross-entropy systems in the corresponding Kaldi recipe for AMI. Our models are slow to train, but we propose improving training speed as an area for future work.
