 ### Input Format
-The input to the model can be a directory containing audio files, in which case the model will perform ASR on English and produces text with punctuation and capitalization:
+Input to Canary can be either a list of paths to audio files or a jsonl manifest file.
 
+If the input is a list of paths, Canary assumes that the audio is English and Transcribes it. I.e., Canary default behaviour is English ASR. 
 ```python
 predicted_text = canary_model.transcribe(
-    audio_dir="<path to directory containing audios>",
