Request for the Mandarin Pinyin acoustic model

[N1vnhil]

I would like to request official support for an acoustic model that uses Pinyin transcription for Mandarin Chinese. Currently, MFA only support Mandarin acoustic model using IPA charset, but many researchers, educators, and developers work with Pinyin romanization, especially in language learning applications, linguistic analysis, and speech technology development.

Adding support for Pinyin-based models would significantly enhance the accessibility and usability of MFA for these communities.

Thank you for considering this request, and keep up the great work!
