How AI is used for real benefits in the real world
At Phonak, we innovate for people. Our advanced AI-powered hearing aids are designed to help people to hear better in the real world, significantly reducing listening effort, and enhancing every conversation.1
Stay ahead in a rapidly evolving field with our AI-powered solutions and educational resources that allow you to work smarter, focus on high-value client care, and achieve higher hearing aid wearer satisfaction.
How does AI help people with hearing aids in the real world?
AI isn’t just a buzzword—it’s making a measurable difference in daily life. Phonak’s AI-powered hearing aid features are engineered to improve how clients hear and function throughout their day.
Built on the Infinio platform, Phonak technology includes AI-driven features like AutoSense OS™ and Spheric Speech Clarity, providing excellent speech understanding from any direction and in a wide range of real-life listening situations. This gives you a flexible solution for diverse client needs.
How does an AI feature like AutoSense™ help clients in the real world?
This is what the data shows:
16 %
better speech understanding1
Clients can follow conversations more clearly—even in noise or group settings.
45 %
reduced listening effort2
Less mental strain means more energy for social connection and participation.
21 %
less listening fatigue by day’s end3
Clients stay engaged longer without the drain of constant audio processing.
Infinio Platform with AutoSense OS: AI-powered precision – seamless adaptation
Your clients don’t live in one environment—so their hearing aids shouldn’t either.
Powered by the Infinio platform, Phonak’s AutoSense OS 7.0 is an AI-trained automatic operating system that continuously analyzes the sound environment—more than 700 times per second—to ensure the hearing aid adapts in real time to what the client needs to hear.
ASOS 7.0 has been trained on 18 times more sound environments than the previous generation, making it the most precise implementation of AutoSense to date—with a 24% increase in classification accuracy, according to technical measures.7
For clients, this means:
Seamless listening transitions from one environment to another
Less need for manual adjustments
Reduced listening effort and improved comfort throughout the day2
For hearing care professionals, this means:
Confidence in consistent performance across real-world situations
Fewer fine-tuning appointments thanks to automatic personalization4
A solution that fits diverse clients lifestyles with minimal intervention
In simple terms, AutoSense OS makes it easier to deliver exceptional outcomes—no matter where life takes your clients.
Spheric Speech Clarity: Advanced speech understanding in noise
Speech in background noise is one of the most difficult challenges for hearing aid users—and a key factor in overall satisfaction.
Phonak’s Spheric Speech Clarity uses deep neural network (DNN)-based denoising to extract, enhance, and integrate speech from any direction. This allows clients to hear what matters most, even in complex acoustic environments.
Spheric Speech Clarity offers proven benefits for your clients:
Clients can engage with friends, family members or colleagues even in the noisiest environments. As there is instant speech separation from noise all around – with an unprecedented 10.2 dB SNR improvement.*5
Clients experience a level of clean and clear speech that surpasses any current technology - truly delivering on “Life is on." Spheric Speech Clarity 2.0 boosts speech understanding by 50%.*8
Clients are able to participate in a lively family dinner, follow an engaging lecture or simply enjoy a heart-to-heart conversation with a friend in a noisy environment. That's the power of exceptional speech clarity. They are 2 to 3x more likely to understand every word, from any direction, compared to two leading competitors.6***
