PerSay was an Israeli start-up company specializing in Voice Biometrics technology. Founded in 2000, its voice biometrics systems are used in the banking, insurance, governments, and telecommunications industries worldwide.[3]


PerSay was founded in February 2000 as a spin-off of Verint Systems (NASDAQ: VRNT), part of the Comverse Technology (Pinksheets: CMVT) group. Its headquarters is in Ra'anana, with an office in New York City. Its main investor was SKFT, which handled the venture capital activity of the Shrem Fudim Kelner group.[2] In April 2004 the company was valued at $2.9 to $3.7 million.[4] In 2010 the company was sold for an undisclosed amount (estimated at 10M-20M USD) to Nuance Communications.[5]


PerSay markets the following products:[6]

  • VocalPassword, a biometric speaker identification system which verifies the speaker during an interaction using a voice application
  • FreeSpeech, a text-independent biometric speaker identification system which verifies a person's identity in the course of natural conversation
  • S.P.I.D., an audio-processing system which searches for a target’s voice in a volume of intercepted calls

PerSay's VocalPassword speaker identification technology has been acquired by Bank Leumi,[7] China Merchants Bank,[3] Bank Hapoalim, Israel Discount Bank, and Caja Madrid;[8] British Telecom,[9] Bell Canada, Vodafone, and Global Bilgi/Turkcell;[8] Sandata,[10] Planet Payment of New York,[11] Huawei,[12] and Barclays Capital and Morgan Stanley.[8]
