Model Training
Deletion Error Problem
- Add one noise phone to alleviate the silence over-training, looks OK.
- Omit sil accuracy in discriminative training
- H smoothing of XEnt and MPE, no significant affect.
- Add one silence arc from start-state to end-state
Big-Model Training
16k
- Done!
8k=
Project
- PingAn

Embedding
- Finish model training. performance/speed/size all looks ok.
- Need further test on embedded device.
Character LM
- Except Sogou-2T, 9-gram has been done.
- Add word boundary tag to Character-LM trainig done
- 9-gram
- Except Weibo & Sogou-2T
- 1e-7(13M) wer17.91 compared with 1e-7(no-boundary,71M) 13.4
- 1e-8(54M) wer17.54
- Prepare specific domain vocabulary
- Dianxin/Baoxian/Dianli
- DT lm training
- ReFr
- Merge Character-LM & word-LM
- Union
- Compose, success.
- 2-step decoding: first, character-based LM. Then, word-based LM.
Problem
- Pingan & Yueyu too much deletion error.
- TDNN deletion error rate > DNN deletion error rate
- TDNN Silence scale is too sensitive for different test cases.
- cmvn causes performance reduction.
SiaSun Robot
- Beam-forming algorithm test
- NN-model based beam-forming
SID
Digit
- Engine Package
