+Facebook's Wav2Vec2 XLS-R fine-tuned for Speech Translation.
+
+This is a [SpeechEncoderDecoderModel](https://huggingface.co/transformers/model_doc/speechencoderdecoder.html) model. 
+The encoder was warm-started from the [`facebook/wav2vec2-xls-r-300m`](https://huggingface.co/facebook/wav2vec2-xls-r-300m) checkpoint and
+the decoder was warm-started from the [`facebook/mbart-large-50`](https://huggingface.co/facebook/mbart-large-50) checkpoint.
+Consequently, the encoder-decoder model was fine-tuned on 21 {lang}-to-English translation pairs of the [Covost2 dataset](https://huggingface.co/datasets/covost2).
+
+For more information, please refer to Section *5.1.2* of the [official XLS-R paper]( ).
