class_docstr: Constructs a Wav2Vec2 processor which wraps a Wav2Vec2 feature extractor, a Wav2Vec2 CTC tokenizer and a decoder
  with language model support into a single processor for language model boosted speech recognition decoding.
  
  Args:
      feature_extractor ([`Wav2Vec2FeatureExtractor`]):
          An instance of [`Wav2Vec2FeatureExtractor`]. The feature extractor is a required input.
      tokenizer ([`Wav2Vec2CTCTokenizer`]):
          An instance of [`Wav2Vec2CTCTokenizer`]. The tokenizer is a required input.
      decoder (`pyctcdecode.BeamSearchDecoderCTC`):
          An instance of [`pyctcdecode.BeamSearchDecoderCTC`]. The decoder is a required input.
docstr: Temporarily sets the processor for processing the target. Useful for encoding the labels when fine-tuning
  Wav2Vec2.
