AutoSense OS™ AI 8.0

AI precision. An even more natural listening experience4

  • Hearing that keeps up: AutoSense OS™ AI 8.0 automatically adapts as clients move through their day, selecting programs and features like Speech in Loud Noise and WindBlock 2.0, helping them transition seamlessly between different listening situations. Enhanced processing supports a more nuanced activation of Spheric Speech Clarity 3.0, helping improve speech understanding and reduce listening effort.5
  • Improved listening experience during changing noise levels: AutoSense OS AI 8.0 introduces a new exit criterion for Spheric Speech in Loud Noise, meaning clients benefit from Spheric Speech Clarity longer. It helps create a more consistent listening experience when noise levels fluctuate. For example, when people move, join or leave groups, or different conversational partners speak.
  • Optimized compression for more natural sound: Adaptive Phonak Digital 4.0 fitting formula now delivers even higher fidelity sound. Newly refined compression parameters provide the optimal compression approach when there are sudden changes in the listening environment. Clients experience an even more natural listening experience.4
