Speech Processing

AM development

Environment

End-to-End

• monophone ASR --Zhiyuan

• MPE
• CTC/nnet3/Kaldi
• more refered ruselts of Kaldi/CTC on 1400h-Chinese and plus 100h English

Adapative learning rate method

• sequence training -Xiangyu

• write a technique report

Mic-Array

• hold
• compute EER with kaldi

Data selection unsupervised learning

• hold
• acoustic feature based submodular using Pingan dataset --zhiyong
• write code to speed up --zhiyong
• curriculum learning --zhiyong

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

• hold
• RNN-DAE has worse performance than DNN-DAE because training dataset is small
• extract real room impulse to generate WSJ reverberation data, and then train RNN-DAE

Speaker recognition

• DNN-ivector framework
• SUSR
• AutoEncoder + metric learning
• binary ivector
• Deep speaker embedding tasks

language vector

• write a paper--zhiyuan

• hold

• language vector is added to multi hidden layers--zhiyuan

• write code done
• check code
• http://192.168.0.51:5555/cgi-bin/cvss/cvss_request.pl?account=zxw&step=view_request&cvssid=480

• RNN language vector

• hold

• language vector into multiple layers --Zhiyuan

• a Chinese paper

• speech rate into multiple layers --Zhiyuan

• verify the code for extra input(s) into DNN

multi-GPU

• multi-stream training --Sheng Su

• write a technique report

• kaldi-nnet3 --Xuewei

• 7*2048 8k 1400h tdnn training Xent done
• nnet3 mpe code is under investigation
• http://192.168.0.51:5555/cgi-bin/cvss/cvss_request.pl?account=zxw&step=view_request&cvssid=472
• Analysed the MPE divergence problem when the context is 10. The reason may be ascribed to the Over-fitting. Large data-set may weaken the over-fitting phenomenon.

• RNN AM training on big dataset --mengyuan

• fix decode bug
• nnet3 lstm & blstm training on sinovoice 120h dataset, using KALDI's default config. but result is worse than tdnn
• Test nnet3-MPE code from Xuewei on sinovoice 120h 16k dataset. Didn't observe performance improvement. There are still some bugs in the code.
• Run nnet3-ctc training on sinovoice 120h 16k dataset. Result looks ok, but worse than normal model.
• Start nnet3-ctc training on sinovoice 4000h 8k dataset.

• train mpe --Zhiyong,Xuewei

• train nnet3 mpe using data from Jietong--Xuewei
• modify code to print stats --Xuewei
• The MPE does not work when the context is 10, need to further investigated--zhiyong
• The nnet1 MPE we test is also based on context 5, may larger context is an inherent problem--zhiyong
• modify code to reduce memory

multi-task

• test according to selt-information neural structure learning --mengyuan

• hold
• write code done
• no significant performance improvement observed

• speech rate learning --xiangyu

• hold
• no significant performance improvement observed
• http://192.168.0.51:5555/cgi-bin/cvss/cvss_request.pl?account=zxw&step=view_request&cvssid=483

get results with extra input of speech rate info --Zhiyuan

30 chinese dataset

• revise syllable text
• add ome words in lexicon, which is applied to training and making graph.
• train and decode 30 chinese data again
• revise the techinique report
• prepare data
• kaldi recipe
