I have two questions:

1. Can we use audio from the Word track for the Phonetic track?

2. Are we allowed to use the Real Class dataset for the Phonetic track, or is it only permitted for the Word track?

@dzunglt24 Yes, per the [Problem Description](https://www.drivendata.org/competitions/308/childrens-word-asr/page/980/#audio), “Training data, including audio and transcripts, can be used across tracks.” This includes the Real Class dataset. Thanks for the question!

Only the subset that you provided, right? Also, can we use external noise datasets (not associated with the ones in the prohibited list) for broader coverage?

I’m not sure what you mean by subset. I’m referring to the provided training data in both tracks. You are allowed to use external data as long as it meets [external data requirements](https://www.drivendata.org/competitions/308/childrens-word-asr/#external-data-and-models). Please refer to the home page and rules for more details.
