Secure voice across your organisation

BT's Pindrop-powered voice biometrics add seamless authentication to our global voice services, securing customers and employees.

A better, safer customer experience

Traditional knowledge-based authentication methods are time-consuming, and can be easy to exploit. BT Voice Biometric Authentication allows customers to use their voice as their password, improving both customer and agent experience while increasing security.

Built into BT Global Voice Services

Pindrop capabilities are integrated into BT's global voice network, working alongside your chosen communications environment and enabling organisations to add advanced authentication and fraud protection as part of their existing BT voice solution.

Every channel. Every interaction. Verified in real-time.

AI-powered attacks are evolving at unprecedented speed. Growing 7x faster than traditional attacks and up 1390% since the end of 2024, they use hyper-realistic deepfakes, automation and adaptive social engineering to bypass traditional trust. BT Voice Biometric Authentication addresses these challenges in real time, using advanced voice intelligence to verify every interaction and establish trust.

How does Pindrop work?

Pindrop Call Security uses advanced signal processing and machine learning to analyse over 2,500 unique audio and metadata features from a phone call. These include characteristics like voice patterns, device type, call behaviour, and network details. Pindrop builds a high-resolution profile of each call, helping detect anomalies, spoofing attempts, SIM swaps and other signs of fraud.

With its multi-layered authentication engine, Pindrop verifies legitimate callers in seconds, even when traditional caller ID methods fall short. Instead of relying on what a caller knows or says, it identifies who they are based on how they sound and how they connect. This proactive approach not only enhances security but also accelerates call handling times.
