Collates the audio and text inputs, as well as their targets, into a padded batch.
Audio inputs are padded by SpeechT5FeatureExtractor's [`~SpeechT5FeatureExtractor.pad`]. Text inputs are padded
by SpeechT5Tokenizer's [`~SpeechT5Tokenizer.pad`].
Valid input combinations are:
- `input_ids` only
- `input_values` only
- `labels` only, either log-mel spectrograms or text tokens
- `input_ids` and log-mel spectrogram `labels`
- `input_values` and text `labels`
Please refer to the docstring of the above two methods for more information.
