Speaker Recognition System

On-Line Speaker Recognition Module. By using this simple web form you can:

  • Add a speaker to database: just select the sound on your hard disk and specify ID (a non-negative integer number associated to speaker).
  • Recognize a speaker: just select the sound from your hard disk, code will return the ID of recognized speaker.
  • Remove database: all data will be deleted (inserted speaker and ID).
  • Code supports 8 and 16 bits WAV format. All sampling frequencies are supported.
Before starting to add new sounds to database it is recommended to delete any existing database. In this way you will be sure that database is initially empty: just click on "Remove Database" button.

We recommend to use for each speaker a sufficient number of training sounds, to improve recognition accuracy. Code has been tested with 239 speakers, 2419 sound files (an average number of 10 sound files for each speaker). The average duration of each sound file is 4.56 seconds, the sample rate is 48000 Hz and the number of bits per sample is 16. Using the Leave-One-Out method we have obtained an excellent recognition rate equal to 85.49% (Top-One recognition rate).
