      Hello all,
      I am using a slightly modified version of the sample English recognition network (Recognition_en.m) provided at https://www.hark.jp/networks/samples-hark-2_2_0.tar.gz.

      I am using the following nodes [parameters]:
      MelFilterBank ->
      MSLSExtraction ->
      Delta [FBANK_COUNT = 13] ->
      FeatureRemover [SELECTOR = <Vector<int> > (an empty vector)] ->
      SpeechRecognitionClient

      I have Julius running separately and the traffic from HARK to Julius appears to be sent correctly. However, I get the following error:

      ........................................................................................................................................................................................................Stat: server-client: connect from 127.0.0.1
      forked process [27700] handles this request
      waiting connection...

      source_id = 6, azimuth = 9.999267, elevation = 0.000000, sec = 1611531646, usec = 391823
      mfc_read() : cnt(112) <> size(192)
      read_count < 0, read_count=-3, veclen=96
      ERROR: FEATURE_INPUT plugin: fvin_read() returns error (-2)
      ### Recognition: 1st pass (LR beam)

      Has anyone seen this error before, and do you have any advice for how to fix it?

      Thank you!

        Thank you for your inquiry.

        We are sorry to inform you that HARK 2.x is no longer supported.
        In version 3.x, Kaldi is supported instead of Julius, so please use that.

        The speech recognition samples for version 3.x are available on GoogleDrive as described in the following page.

        Best regards,
        HARK support team
