• LM count files still undelivered!

DNN progress

Sparse DNN

• Optimal Brain Damage(OBD). The initial test shows worse results in weight-cutting experiments compared with simple weight-based cutting.

N/A

Noisy training

1. With 863 clean test, by adding car & white noise at various levels, obtained significant performance improvement.

2. The test with both car & white noise benefits from the noisy training.

Continuous LM

1. Lattice rescoring toolkit is ready. 2. Rescoring is slow with some dense lattices.

QA LM

1. use the QA word segment system 2. train the Q LM & QA ASR system
