In February 2016, HSBC announced that it was making voice authentication available to more than 15 million HSBC UK and First Direct customers by the end of the third quarter of the year, making it the largest roll out of this type of biometric technology in the UK to date.
Instead of verifying a customer through a traditional password or PIN, their voice is assessed against more than 100 indicators from behavioural measures, such as cadence and pitch, to physical measures, such as the size of their larynx and vocal tract.
