Nokia Corporation NOK, in collaboration with Vodafone Group VOD and RingCentral, is set to unveil Immersive Voice and Audio Services (IVAS) at MWC 2025, offering a breakthrough in voice communication. IVAS introduces a three-dimensional, spatial audio experience, making conversations more lifelike and engaging, even in remote settings. This cutting-edge technology aims to enhance business, industrial and consumer communications, elevating everything from remote meetings to industrial operations and everyday voice calls.
IVAS enhances traditional voice services by enabling users to hear sound spatially in real-time, improving clarity, engagement and comprehension. This breakthrough has significant applications across business communication, industrial operations, education, sports and mobile calls. From multi-stream teleconferencing that makes virtual meetings more immersive to artificial intelligence (AI)-enhanced collaboration and inclusive soundscapes for visually impaired users, IVAS aims to revolutionize voice interaction.
Developed through the alliance of 13 companies, the IVAS standard has been integrated into 3GPP Release 18, building upon Enhanced Voice Services (EVS) or HD Voice+. A key innovation in this development is Metadata-Assisted Spatial Audio (MASA), a new parametric audio format designed for smartphones and compact devices with spatial audio constraints. The IVAS codec includes a built-in renderer supporting head-tracked binaural audio and multi-loudspeaker playback, enabling immersive experiences.

At MWC 2025, visitors can explore IVAS technology through multi-stream teleconferencing, which spatially distinguishes voices to improve clarity, engagement and inclusivity for remote participants. Immersive 1-to-1 calling enhances voice interactions with 360-degree audio and accurate directional sound using head-tracking-enabled headphones. In industrial environments, IVAS supports remote servicing by isolating machine sounds and improving communication in high-noise workplaces. With its broad applications, IVAS meets the growing demand for enhanced voice and immersive multimedia services, setting the stage for the future of spatial audio communication.
Visitors to MWC 2025 from March 3-6 can explore the next-generation IVAS technology at Vodafone’s booth, Nokia’s booth or RingCentral’s Executive Meeting Room. This demonstration highlights future voice communication possibilities, powered by 5G Advanced IVAS codec and Nokia’s Immersive Voice technology.
