ReSound Vivia 4 is an entry-to-mid technology level model in the new ReSound Vivia family. It uses ReSound’s Intelligence Augmented™ platform, combining traditional hearing processing with AI-based speech enhancement to improve hearing in noisy environments.

Key Specifications

Core Technology

Intelligence Augmented™

Unlike fully automated AI systems, ReSound’s approach supports the brain’s natural way of processing sound rather than replacing it.

Benefits:

• Better speech understanding
• Less listening effort
• More natural sound perception
• Improved hearing in busy environments such as restaurants and meetings

The Vivia platform is powered by a Dual-Chip architecture that includes a dedicated Deep Neural Network (DNN) chip trained on millions of speech samples.
