Speech Processing

AM development

Environment

  • grid-11 often shut down automatically, too slow computation speed.
  • New grid-13 added, using gpu970
  • To update the wiki enviroment infomation

RNN AM

Mic-Array

  • Change the prediction from fbank to spectrum features
  • investigate alpha parameter in time domian and frquency domain
  • ALPHA>=0, using data generated by reverber toolkit
  • consider theta

RNN-DAE(Deep based Auto-Encode-RNN)

Speaker ID

Ivector&Dvector based ASR

Dark knowledge

  • Ensemble
  • adaptation for chinglish under investigation --Mengyuan Zhao
  • Try to improve the chinglish performance extremly
  • unsupervised training with wsj contributes to aurora4 model --Xiangyu Zeng
  • test large database with AMIDA
