O2 and Mavenir trial network-based call audio support in the UK
TL;DR: O2 said it completed a proof-of-concept trial with Mavenir in the UK to improve phone call clarity for customers with hearing loss using network-based audio processing. Participants kept their existing phone and mobile number, completed an automated hearing test, and received a personalised hearing profile linked to their number. O2 said nearly 90% of participants reported improved call clarity after the trial.
O2 completed a proof-of-concept trial with Mavenir in the UK to test network-based technology that adapts phone call audio in real time for customers with hearing loss. O2 said participants used their existing phone and mobile number during the trial, while the audio optimisation ran within O2's network rather than through a device feature or third-party app.
O2 said participants first completed a short automated hearing test to measure how they perceive different sound frequencies. The test generated a personalised hearing profile that O2 said was securely linked to the participant's mobile number, allowing the network to tailor speech delivery during calls to that individual's hearing needs.
O2 said nearly 90% of participants reported improved call clarity after the trial. The company also said participants reported conversations were easier to follow, with fewer misunderstandings, reduced listening effort, and a more natural calling experience. O2 described the work as an early-stage proof of concept developed with Mavenir, a network software supplier.
