	<span>Overview
	</span></h2>

<p>The M-CTC-T model was proposed in <a href="https://arxiv.org/abs/2111.00161" rel="nofollow">Pseudo-Labeling For Massively Multilingual Speech Recognition</a> by Loren Lugosch, Tatiana Likhomanenko, Gabriel Synnaeve, and Ronan Collobert. The model is a 1B-param transformer encoder, with a CTC head over 8065 character labels and a language identification head over 60 language ID labels. It is trained on Common Voice (version 6.1, December 2020 release) and VoxPopuli. After training on Common Voice and VoxPopuli, the model is trained on Common Voice only. The labels are unnormalized character-level transcripts (punctuation and capitalization are not removed). The model takes as input Mel filterbank features from a 16Khz audio signal.</p>
<p>The abstract from the paper is the following:</p>
<p><em>Semi-supervised learning through pseudo-labeling has become a staple of state-of-the-art monolingual
speech recognition systems. In this work, we extend pseudo-labeling to massively multilingual speech
recognition with 60 languages. We propose a simple pseudo-labeling recipe that works well even
with low-resource languages: train a supervised multilingual model, fine-tune it with semi-supervised
learning on a target language, generate pseudo-labels for that language, and train a final model using
pseudo-labels for all languages, either from scratch or by fine-tuning. Experiments on the labeled
Common Voice and unlabeled VoxPopuli datasets show that our recipe can yield a model with better
performance for many languages that also transfers well to LibriSpeech.</em></p>

<p>This is the configuration class to store the configuration of a <a href="/docs/transformers/pr_19907/en/model_doc/mctct#transformers.MCTCTModel">MCTCTModel</a>. It is used to instantiate an
M-CTC-T model according to the specified arguments, defining the model architecture. Instantiating a configuration
with the defaults will yield a similar configuration to that of the M-CTC-T
<a href="https://huggingface.co/speechbrain/m-ctc-t-large" rel="nofollow">speechbrain/m-ctc-t-large</a> architecture.</p>
<p>Configuration objects inherit from <a href="/docs/transformers/pr_19907/en/main_classes/configuration#transformers.PretrainedConfig">PretrainedConfig</a> and can be used to control the model outputs. Read the
documentation from <a href="/docs/transformers/pr_19907/en/main_classes/configuration#transformers.PretrainedConfig">PretrainedConfig</a> for more information.</p>

<p>Constructs a M-CTC-T feature extractor.</p>
<p>This feature extractor inherits from <a href="/docs/transformers/pr_19907/en/main_classes/feature_extractor#transformers.SequenceFeatureExtractor">SequenceFeatureExtractor</a> which contains
most of the main methods. Users should refer to this superclass for more information regarding those methods. This
code has been adapted from Flashlight’s C++ code. For more information about the implementation, one can refer to
this <a href="https://colab.research.google.com/drive/1GLtINkkhzms-IsdcGy_-tVCkv0qNF-Gt#scrollTo=pMCRGMmUC_an" rel="nofollow">notebook</a>
that takes the user step-by-step in the implementation.</p>
