This is the trained Mandarin phone-token CTC model used by the See My Voice
pronunciation practice app.
1你 ni2 -> I_n F_i T2
2好 hao3 -> I_h F_ao T3
3是 shi4 -> I_sh F_i_zh T4
4字 zi4 -> I_z F_i_z T4
5儿 er2 -> F_er T2
6女 nv3 -> I_n F_v T3
The training run kept the large acoustic encoder frozen and trained the CTC
output head for the See My Voice phone-token target space.
This model is intended for the See My Voice pronunciation feedback service. The
service compares expected Mandarin phone tokens for a target sentence against
the model's predicted phone tokens from learner audio.
This is an early project model, not a production-grade Mandarin pronunciation
assessment model. It was trained on a small dataset and should be treated as a
prototype signal for initial/final/tone feedback rather than a definitive
linguistic or educational assessment.
