Proposal for the integration of Tree-constrained Pointer Generator and Minimum Biasing Word Error (MBWE) training for contextual ASR

### 🚀 The feature I’d like to propose the integration of tree-constrained pointer generator (TCPGen) [1] and Minimum Biasing Word Error (MBWE) training [2] for contextual biasing into torchaudio package....

RNNT Loss Accepting Log Probabilities

### 🚀 The feature @carolineechen The current RNNT loss takes logits as inputs. I wonder if it is possible to have a version that takes log probabilities rather than logits....
