Customer analytics software firm Verint has bought Victrio, a voice biometrics company.

The acquisition will let Verint add "voice fingerprints" to its data systems as a means to improve its customers' security and reduce the risk of fraud, the company announced Tuesday. Verint plans to release a version of its Workforce Optimization recording and speech analytics system that integrates Victrio's speech-analysis tools.

The integrated system will use Victrio's so-called passive voice biometrics to reduce the risk of fraud and will be offered to financial institutions including banks, card issuers and asset managers, Verint said.

"This acquisition extends our offering and introduces a host of advanced capabilities that will enable us to offer our customers an even more comprehensive solution to address fraud and identity authentication problems head on," said Elan Moriah, president of Verint's enterprise intelligence division, in the news release.
