The voice biometrics technology will cross-check more than 100 unique identifiers.

It incorporates both behavioural features like speed, cadence and pronunciation, and physical aspects including the shape of larynx, vocal tract and nasal passages.

The customers who wish to opt-in should enrol their voice print, allowing them not to remember or recite their existing telephone security password letters or PIN.

The new security processes will allow customers to access their accounts via advanced technologies that use the characteristics of an individual’s body, specifically voice and fingerprint, to verify an account holder’s identity.

HSBC global head of contact centres for retail banking and wealth management Warren Buckley said: "The biometrics technology behind Voice ID focusses on how we speak, not what we say. It doesn’t matter what language a customer speaks, if they have a cold or sore throat, Voice ID will be able to confirm their identity.

"Remembering the right password and PIN is challenging and customers get frustrated when they fail the security process and have to reset their details.

"Having one less telephone security number or PIN to remember will speed up the verification process and give the customer more time to spend talking about their financial needs."

It is claimed to be the largest planned roll out of voice biometric security technology in the UK. The company will roll out the technology in Hong Kong, Mexico, Canada, US and France, subject to regulatory approvals.

The company plans to deploy the service to more markets in the next two years.
