How the Audéo Sphere Infinio’s DEEPSONIC Chip Revolutionises Speech Clarity in Noisy Environments

Hearing in noisy environments has always been one of the most common challenges for hearing aid users, whether they are new wearers or experienced ones1. Crowded cafés, bustling shopping centres, or noisy family gatherings can all make it difficult for people with hearing loss to connect and communicate. Even with advances in hearing aid technology, background noise remains a consistent obstacle to speech clarity.

Now, thanks to groundbreaking innovation from Phonak, a new chapter in hearing clarity is being written. Their latest product line, Audéo Sphere Infinio, sets a new benchmark in speech understanding – all because of a revolutionary new approach to sound processing through Phonak’s DEEPSONIC™ chip.

The Challenge of Background Noise

Even the best hearing aids have traditionally struggled with background noise. Conventional noise reduction techniques, such as directional microphones and beamformers, have delivered only incremental improvements – and their performance has plateaued in recent years.

These traditional methods can struggle when noise comes from multiple directions, making real-world conversations challenging.

Moreover, most hearing aids share one processor for all tasks, limiting their ability to manage complex sound environments effectively. Phonak’s DEEPSONIC™ chip represents a true paradigm shift, taking hearing technology to entirely new heights by prioritising advanced speech understanding in noise.

Meet DEEPSONIC™: The Power Behind Spheric Speech Clarity

The Audéo Sphere Infinio features the world’s first dedicated deep neural network (DNN) processor designed specifically for hearing aids – the DEEPSONIC™ chip. Unlike traditional devices, Audéo Sphere Infinio uses a dual-chip architecture: one chip (ERA) manages standard signal processing, while DEEPSONIC™ is devoted entirely to advanced, AI-powered noise reduction.

DEEPSONIC™ is 53 times more powerful than anything else currently available in the hearing aid industry and can perform an incredible 7.7 billion operations per second. It’s been trained on more than 22 million sound samples to understand the unique characteristics of everyday listening environments — allowing it to accurately separate speech from background noise in real time.

Those numbers might sound a bit technical, so what does this actually mean for your hearing? The immense power of DEEPSONIC™ drives a specific feature called Spheric Speech Clarity – a breakthrough that delivers dramatic improvements in speech understanding from all directions. This translates to a remarkable 10 dB improvement in the signal-to-noise ratio, meaning wearers can hear conversations more clearly, even in the most challenging situations.

Clinical studies have shown that Spheric Speech Clarity can double your chances of understanding speech in complex, noisy environments, improving speech comprehension by up to 36.8% compared to leading competitor hearing aids.

So, whether you’re facing someone directly, chatting beside a friend in a noisy restaurant, walking through a crowded shopping centre, or enjoying a coffee in a bustling café, the Audéo Sphere Infinio works seamlessly to isolate the voice you want to hear – and filter out the rest.

AI Used for a Purpose – Not Just Marketing Hype

In 2025, it can feel like every product on the market boasts some kind of “revolutionary” AI feature – from PCs and smartphones to televisions and even fridges. But unlike many of these marketing-driven add-ons, Phonak’s Audéo Sphere Infinio delivers a genuine and meaningful leap in artificial intelligence for hearing aids – with a clear and purposeful benefit for the user.

One major reason for this is that Phonak is no newcomer to AI. In fact, they’ve been incorporating AI elements into their hearing aid processing for over 20 years – that’s right, more than two decades! Phonak isn’t just jumping on the AI bandwagon; for them, that wagon left long ago – and their experience shows.

With Spheric Speech Clarity, Phonak has introduced a truly game-changing application: AI that actively cleans the sound you hear in real time, removing unwanted noise while preserving speech clarity and naturalness – from any direction.
