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.
Empower your practice today and shape the future of hearing healthcare
AI is fundamentally transforming the hearing journey for both professionals and clients. By enhancing diagnostics, it allows for earlier and more accurate identification of hearing loss, enabling tailored treatment plans that meet individual needs. AI also supports ongoing aftercare, ensuring clients receive continuous support long after their initial fitting.
New educational series!
Hearing care of the future:
AI in audiology.
The educational series is your gateway to the future of hearing care. It gives hearing care professionals and clinic owners an early look at emerging AI applications—not just in technology, but in business strategy, client counseling, and clinical efficiency.
A select group of global AI experts, including Phonak’s own thought leaders, share cutting-edge insights in a series of high-quality, engaging webinars—each designed to inspire, educate, and equip you for what’s ahead.
How does AI help people with hearing aids in the real world?

How does an AI features like AutoSense™ can 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 6.0 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.
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 patients 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 far beyond any existing technology. Meaning they truly get the experience of “Life is on.” With Audéo Sphere, Speech understanding increased by up to 36.7%.6**
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.There are 2 to 3x more likely to understand every word, from any direction, compared to two leading competitors.6***
Discover the science behind Infinio: Real-world results, backed by evidence
The Infinio platform isn’t just built on innovation—it’s proven by research. From controlled lab settings to real-life environments, Phonak continues to validate the performance of its AI-powered hearing technology, ensuring real-world benefits for clients.
Field study – Huang, HY. et al., 2025
This study investigated the effect of a Deep Neural Network (DNN) signal processing noise reduction feature, Spheric Speech Clarity, on cognitive function. The feature, introduced with the Phonak Infinio platform, showed significant effects on interference control and working memory capacity while listening in noise.
Field study – Miller, A. et al., October 2024
This study highlights spontaneous user preference for Phonak Audéo Sphere™ Infinio in daily listening conditions—underscoring its value in real-world patient satisfaction.
Field study – Raufer, S. et al., 2024
Speech understanding in noise is one of the biggest challenges for hearing aid users. This study confirms that Spheric Speech Clarity delivers measurable improvements in speech clarity compared to leading alternatives.
