WebThis configuration was used for the base model trained on the Librispeech dataset in the wav2vec 2.0 paper. Note that this was tested with pytorch 1.4.0 and the input is expected to be single channel, sampled at 16 kHz. Note: you can simulate 64 GPUs by using k GPUs and setting --update-freq 64/k. WebWith the Distilled VQ-VAE model, the discrete codes are trained to minimize a likelihood-based loss. As a result, the encoder tends to focus on capturing the key of the fragments, as was the case with the VQ-CPC codes with random negative sampling. However, we observe that the range of the soprano voice is also captured: the maximal range of ...
WebFrom CPC to wav2vec CPC is a general framework Wav2vec = CPC applied specifically for ASR Encoder (x -> z): 5-layer convolutional network with Kernels: (10, 8, 4, 4, 4) Strides: (5, 4, 2, 2, 2) Receptive field: 30 ms of data at 16 KHz, 10 ms hop Context (z -> c): 9 CNN layers with kernel size = 3 and stride = 1 WebModified CPC [modified_cpc] and wav2vec [wav2vec] proposed several architecture changes to improve CPC. vq-wav2vec introduces a VQ module to wav2vec. The module discretizes speech into a sequence of tokens after InfoNCE pretraining. Tokens are used as pseudo-text to train a BERT as did in NLP for contextualized representations. wav2vec …
