Model overview

The w2v-bert-2.0 is a Conformer-based speech encoder model open-sourced by Facebook. It was pre-trained on 4.5 million hours of unlabeled audio data covering over 143 languages and can be fine-tuned for downstream tasks like Automatic Speech Recognition (ASR) or Audio Classification. The model has 600 million parameters and is supported by the Transformers library.

Similar models include Wav2Vec2-Base-960h, a base model pre-trained and fine-tuned on 960 hours of Librispeech, and Wav2Vec2-Base, the base model pre-trained on 16kHz speech audio. These models demonstrate the effectiveness of learning representations from speech audio alone and then fine-tuning on labeled data.

Model inputs and outputs

Inputs

  • Raw audio waveforms

wav2vec2-base is a speech recognition model developed by Facebook's AI team. It is the base version of their Wav2Vec2 model, which learns powerful representations from speech audio alone and can outperform semi-supervised methods when fine-tuned on labeled speech data. The similar wav2vec2-base-960h model is the base model further pre-trained and fine-tuned on 960 hours of LibriSpeech data, achieving strong speech recognition performance with 1.8/3.3 WER on the LibriSpeech clean/other test sets. The wav2vec2-large-960h-lv60-self model is a larger variant that was trained with a self-training objective, resulting in even lower WER of 1.9/3.9. Facebook has also released the wav2vec2-xls-r-300m model, a large-scale multilingual pre-trained model with 300 million parameters, trained on 436K hours of speech data across 128 languages. This model can be fine-tuned for a variety of speech tasks like automatic speech recognition, translation, and classification. Model inputs and outputs Inputs Speech audio**: The model takes in raw waveform audio as input, which must be sampled at 16kHz. Outputs Text transcription**: The model outputs a text transcription of the input speech audio. Capabilities The wav2vec2-base model has been shown to achieve strong speech recognition performance, even when fine-tuned on small amounts of labeled data. For example, with just 1 hour of labeled data, it can outperform previous state-of-the-art models trained on 100 hours. This demonstrates the feasibility of building accurate speech recognition systems with limited labeled data. What can I use it for? The wav2vec2-base model can be used as a foundation for building automatic speech recognition (ASR) systems. By fine-tuning the model on domain-specific labeled data, you can create highly accurate transcription models for applications like voice interfaces, video captioning, or meeting transcription. Things to try To use wav2vec2-base for speech recognition, you'll need to create a custom tokenizer and fine-tune the model on labeled text data, as it was pre-trained on audio alone without any text labels. Check out this blog post for a step-by-step guide on how to fine-tune the model for English ASR. You can also explore using the larger, more powerful wav2vec2-large-960h-lv60-self or multilingual wav2vec2-xls-r-300m models if you need higher accuracy or support for multiple languages.

The hubert-large-ls960-ft model is a large version of Facebook's Hubert speech recognition model that has been fine-tuned on 960 hours of Librispeech data. Hubert is a self-supervised model for learning speech representations, which was proposed in the Hubert paper. Compared to other Wav2Vec2 models from Facebook like wav2vec2-large-960h-lv60-self, the hubert-large-ls960-ft model is specifically fine-tuned on less data (960 hours vs. 960+53k hours) but achieves strong performance on speech recognition tasks. Model inputs and outputs Inputs Audio**: The model takes in raw audio data sampled at 16kHz as input. Outputs Transcription**: The model outputs a transcription of the input audio in the same language as the audio. Capabilities The hubert-large-ls960-ft model demonstrates strong speech recognition capabilities, especially on the Librispeech benchmark. Compared to the base Hubert model, the fine-tuned version shows up to 19% and 13% relative WER reduction on the more challenging dev-other and test-other evaluation subsets of Librispeech. What can I use it for? The hubert-large-ls960-ft model can be used for automatic speech recognition (ASR) tasks, particularly transcribing English audio. The model's strong performance on the Librispeech benchmark suggests it would be a good choice for transcribing high-quality, read speech in English. However, the model may not perform as well on more diverse, spontaneous speech. Things to try One interesting aspect of the hubert-large-ls960-ft model is that it was fine-tuned on a relatively small amount of data (960 hours) compared to larger speech models. This suggests the base Hubert model is able to learn strong speech representations that can be effectively fine-tuned on domain-specific data. Experimenting with fine-tuning the base Hubert model on your own dataset could be a promising avenue to explore.
