• Abstract summary: We study the efficacy of continued pretraining (CPT) in adapting Wav2vec2.0 to the classroom domain. We show that CPT is a powerful tool in that regard and reduces the Word Error Rate (WER) of Wav2vec2.0-based models by upwards of 10%.

• Abstract: Creating Automatic Speech Recognition (ASR) systems that are robust and resilient to classroom conditions is paramount to the development of AI tools to aid teachers and students. In this work, we study the efficacy of continued pretraining (CPT) in adapting Wav2vec2.0 to the classroom domain. We show that CPT is a powerful tool in that regard and reduces the Word Error Rate (WER) of Wav2vec2.0-based models by upwards of 10%. More specifically, CPT improves the model's robustness to different noises, microphones, classroom conditions as well as classroom demographics. Our CPT models show improved ability to generalize to different demographics unseen in the labeled finetuning data.

  We investigate the use of automatically-generated transcriptions of unlabelled datasets to increase the training set size. We demonstrate that increasing the size of the training set, a recent trend in the literature, leads to reduced WER despite using noisy transcriptions. The proposed model achieves new state-of-the-art performance on AV-ASR on LRS2 and LRS3.

  Self-supervised Transformer based models, such as wav2vec 2.0 and HuBERT, have produced significant improvements over existing approaches to automatic speech recognition (ASR) We show CoPT results in word error rates (WERs) equal to or slightly better than using semi-supervised training (SST) In addition, we show that using the CoPT model for pseudo-labeling, and using these labels in SST, results in further improvements in WER.

Our results for models pre-trained on 960h Librispeech dataset and fine-tuned on 10h of transcribed data show that using the same model, we get a smooth trade-off between word error rate (WER) and inference time.

  wav2vec 2.0 can be used for speech emotion recognition (SER) Two baseline methods, vanilla fine-tuning (V-FT) and task adaptive pretraining (TAPT) are first presented. We show V-FT is able to outperform state-of-the-art models on the IEMOCAP dataset. We also introduce a novel fine-tuning method termed P-TAPT, which modifies the TAPT objective to learn contextualized emotion representations.
