• using pocketsphinx_continuous with a .wav file

  3 avril 2013, par user2242131

  I am attempting to write an application that will allow a user to speak a small set of commands from a remote system and have them executed on my server. Using pocketsphinx to parse the spoken text. When run locally with the microphone, pocketsphinx_continuous works perfectly no matter how I slur the words. But when importing the audio file and using ffmpeg to downsample the audio to a single channel, 16 bit PCM file, it will parse the first word without difficulty. Then it will skip everything else and treat it as . I am confident that the problem is in the file format and not in the pocketsphinx configuration.

  Using command line
  ffmpeg -y -i Sound\AddSheet.wav -ac 1 -f s16le -acodec pcm_s16le -ar 16k AddTmp.wav
  in a batch file.

  The bottom of the output I get is :

  INFO: fsg_search.c(1407): Start node ADD.0:5:47
  
  INFO: fsg_search.c(1407): Start node <sil>.0:2:49
  
  INFO: fsg_search.c(1446): End node <sil>.126:128:305 (-486)
  
  INFO: fsg_search.c(1662): lattice start node <s>.0 end node <sil>.126
  
  INFO: ps_lattice.c(1352): Normalizer P(O) = alpha(<sil>:126:305) = -175371
  
  INFO: ps_lattice.c(1390): Joint P(O,S) = -176076 P(S|O) = -705
  
  000000000: ADD USER
  
  </sil></sil></s></sil></sil>

  Which is not the audio in the file. The words spoken in the file are "ADD SPREADSHEET", which works perfectly from the same microphone without the intervening .wav file.

  I have tried increasing the audio volume and decreasing the background noise using sox :

  sox -v 3.0 Sound\%1 Sound\%1-loud.wav ffmpeg -i Sound\%1-loud.wav -vn -ss 00:00:00 -t 00:00:01 -y Sound\%1-noiseaud.wav 
  
  sox Sound\%1-noiseaud.wav -n noiseprof Sound\%1-noise.prof 
  
  sox Sound\%1 Sound\%1-clean.wav noisered sound\noise.prof 0.21 
  
  ffmpeg -y -i Sound\%1-clean.wav -ac 1 -f s16le -acodec pcm_s16le -ar 16k AddTmp.wav

  with no noticeable effect on the final results.

  If you look at the output you will notice that fsg_search.c has found ADD as the start node, then silence for the remainder. Please help on this.

• UnsupportedAudioFileException in LIUM Speaker Diarization after re-sampling

  14 septembre 2016, par RAVI D PARIKH

  I am trying to configure LIUM tool for speaker diarization. This question is a follow up of UnsupportedAudioFileException in LIUM Speaker Diarization

  I have tried re sampling the file using sox and ffmpeg

  I am new to any sorts of programming and i have followed all steps described in LIUM quick start guide and the above link. I still get the same error. I think my input file has issues related to header as mentioned by Nikolay Shmyrev in the above link however i have no clue on how to solve it.

  My code is as below :

  java –jar  C:\Users\Ravi\Desktop\LIUM_SpkDiarization-8.4.1.jar \ --fInputMask= C:\Users\Ravi\Desktop\converted_f2.wav--sOutputMask= C:\Users\Ravi\Desktop\converted_converted_2.seg -–help --doCEClustering

  Error :

  10:52.037 SEVERE AudioFeatureSetFa  FileNotFoundException
  
  java.io.FileNotFoundException:

          at fr.lium.spkDiarization.libFeature.AudioFeatureSetFactory.MakeFeature(AudioFeatureSetFactory.java:207)
  
  </init>

  The input file is at https://drive.google.com/file/d/0B7Fqe9EX5JbgT09BcXpSREd4em8/view?usp=sharing

  Input File Name:converted_f2.wav

  I have put the command and the full output of the prompt in a word document at

  https://drive.google.com/file/d/0B7Fqe9EX5JbgUUl6THNCZFgxRnM/view?usp=sharing

  The inpiut file has correct sampling rate and other parameters and thus i am not able to understand the cause of the error.
  Thanks a lot for the help
