Multi-Span Acoustic Modelling using Raw Waveform Signals

21 Jun 2019Patrick von PlatenChao ZhangPhilip Woodland

Traditional automatic speech recognition (ASR) systems often use an acoustic model (AM) built on handcrafted acoustic features, such as log Mel-filter bank (FBANK) values. Recent studies found that AMs with convolutional neural networks (CNNs) can directly use the raw waveform signal as input... (read more)
