What's the meaning of * in pronounced-phone when having mispronunciations?

[tangYang7]

Hello, First of all, thank you for developing this corpus.

I noticed that there are new labels in score.json and have some question since there are no directions to answer it. I'm wondering what is after a phone in pronounced-phone, such as T, AH, or R below the following example.

Thank you very much for your time and assistance!

Best regards.
