Гибридная ИИ-система от Google, объединившая лучшие наработки в области распознавания речи. Использование архитектуры Conformer и метода Noisy Student позволило этой нейросети установить мировой рекорд точности на наборе данных LibriSpeech.
We employ a combination of recent developments in semi-supervised learning for automatic speech recognition to obtain state-of-the-art results on LibriSpeech utilizing the unlabeled audio of the Libri-Light dataset. More precisely, we carry out noisy student training with SpecAugment using giant Conformer models pre-trained using wav2vec 2.0 pre-training. By doing so, we are able to achieve word-error-rates (WERs) 1.4%/2.6% on the LibriSpeech test/test-other sets against the current state-of-the-art WERs 1.7%/3.3%.
