Name of the Project: COST250 – COST ACTION 250: Speaker Recognition in Telephony
Duration: 1/16/1995 – 9/30/1999


The primary aim of the project is to improve the technology of speaker recognition by

  • improving knowledge of the problem
  • evaluating current techniques and products
  • investigating novel techniques.

The focus of the project is speaker recognition/verification over telephone lines, but knowledge gained is also of value to other areas e.g. standardisation of measurement techniques and forensic testing.


  • Polycost – a common database on which COST250 partners can compare and validate their speaker recognition
  • Reference system – a commonly available reference speaker verification system
  • A survey of databases for speaker recognition.
