When it comes to how humans communicate with each other or with machines, voice is a major interface, with growth in the latter fuelled by the rise of artificial intelligence, faster computing technology and an explosion of new devices — some of which only, or primarily, work with voice commands. But the supreme reign of voice has also opened a window of opportunity for malicious hackers — specifically, in the area of voice fraud.
Now, a security startup called Pindrop is announcing that it has raised $90 million to tackle this with a platform that it says can identify even the most sophisticated impersonations and hacking attempts, by analysing nearly 1,400 acoustic attributes to verify if a caller or a voice command is legit.
“We live in a brave new world where everything you thought you knew about security needs to be challenged,” said Vijay Balasubramaniyan, co-founder, CEO and CTO of Pindrop, who built the company (with co-founders Ahamad Mustaque and Paul Judge) originally out of his PhD thesis.
The funding is a growth round aimed specifically at two areas. First, taking US-based Pindrop into more international markets, starting with Europe — Vijay spoke to me in London — and coming soon to Asia. And second, to expand from customer service scenarios — the vast majority of its business today — into any applications that use voice interfaces, such as connected car platforms, home security devices, smart offices and smart home speakers.
