Question
How has AI evolved with Phonak Infinio devices?
Answer
The next generation of Phonak AI: Spheric Speech Clarity 2.0

The launch of Infinio Sphere, the first hearing aid to feature a dedicated AI chip, DEEPSONIC™, was a groundbreaking moment for both Phonak and the broader audiology field. Now is the time for the next generation with the Introduction of Spheric Speech Clarity 2.0 in Infinio Ultra Sphere.
Just like the original version, the sophisticated Deep Neural Network (DNN)-based Spheric Speech Clarity 2.0 feature extracts, enhances, and integrates speech in real-time to deliver unprecedented speech clarity in noise from any direction. Now it is more energy efficient, giving patients more access to the ground-breaking performance, even during their longest days.
The Scientific Result
With Infinio Ultra Sphere, Phonak is introducing Spheric Speech Clarity 2.0, featuring a retrained DNN model. This powerful new architecture allows the system to be 30% more efficient than its predecessor, ensuring patients can benefit from high-level processing all day long. The result is instant, all-around speech understanding in noise, delivering an unprecedented 10.2 dB SNR improvement in real-world scenarios.1

The Human Result
By leveraging a dedicated AI chip with advanced separation of speech from noise, Infinio Ultra Sphere provides up to 37% reduction in listening effort.2 Users are three times more likely to understand every word compared to other brands3 and experience significantly less daily fatigue.2 Ultimately, the evolution to Spheric Speech Clarity 2.0 transforms challenging environments like crowded cafés into spaces where conversation feels natural and effortless.
