DistilHuBERT DistilHuBERT by NTU Speech Processing & Machine Learning Lab The base model pretrained on 16kHz sampled speech audio. When using the model make sure that your speech input is also sampled at 16Khz. Note : This model does not have a tokenizer as it was pretrained on audio alone. In order to use this model speech recognition , a tokenizer should be created and the model should be fine tuned on labeled text data. Check out this blog for more in detail explanation of how to fine tune the model. Paper: DistilHuBERT: Speech Representation Learning by Layer wise Distillation of Hidden unit BERT Authors: Heng Jui Chang, Shu wen Yang, Hung yi Lee Abstract Self supervised speech representation learning methods like wav2vec 2.0 and Hidden unit BERT (HuBERT) leverage unlabeled speech data for pre training and offer good representations for numerous speech processing tasks. Despite the success of these methods, they require large memory and high pre training costs, making them inaccessible for researchers in academia and small companies. Therefore, this paper introduces DistilHuBERT, a novel multi task learning framework to distill hidden representations from a HuBERT model directl…
