Phonak Audéo Sphere™ Infinio: Hearing AI That Changes Everything
The world’s first hearing aid to use Spheric Speech Clarity — an AI that listens in every direction so you never miss a word, wherever the conversation comes from.

The Problem Every Hearing Aid Has Been Trying to Solve
For decades, hearing aids have been designed around one assumption: the person you’re talking to is in front of you. Directional microphones, beamforming, zoom features — all of them point forward. But real conversations don’t work that way. In a restaurant, a classroom, a family gathering, or a busy Delhi market, voices come at you from every direction simultaneously.
Traditional hearing aids handle this with a compromise — they try to suppress noise from the sides and back while amplifying from the front. The result? You can hear the person in front of you better, but you constantly miss comments from beside or behind you, feel disoriented in social settings, and struggle to participate fully in group conversations.
Phonak’s engineers looked at this problem differently. Instead of asking “how do we block noise better?”, they asked: “What if we could make speech intelligible from every direction at once?” The answer is Spheric Speech Clarity.
The Core Innovation: Spheric Speech Clarity
| BREAKTHROUGH FEATURE — Spheric Speech Clarity Spheric Speech Clarity is a purpose-built AI processor that analyses speech signals arriving from all 360° around the wearer simultaneously. Unlike conventional directional processing, it doesn’t sacrifice awareness in one direction to improve it in another — it uses AI to lift speech out of noise regardless of where the speaker is standing. Phonak’s own clinical data claims it can double your chances of understanding speech from any direction in noise. |
The Infinio 90 carries Spheric Speech Clarity at full strength — the complete AI model running at maximum computational depth. The Infinio 70 carries it at medium strength, delivering a meaningful upgrade over conventional hearing aids while sitting at a more accessible price point. Both models also include SpeechSensor, which intelligently monitors the wearer’s head movements and conversational context to fine-tune sound processing in real time.
| AUDIOLOGIST’S INSIGHT “Spheric Speech Clarity doesn’t just hear better in one direction — it makes every direction a clear direction. This is the most meaningful shift in hearing aid processing in over a decade.” |
AutoSense OS 7.0: The Brain That Never Sleeps
Every Phonak Audéo Sphere Infinio runs on AutoSense OS 7.0, Phonak’s most advanced automatic situation detection platform. The OS continuously scans the acoustic environment — hundreds of times per second — and categorises it into scenarios like Speech in Loud Noise, Music, Speech in Car, Comfort in Noise, Calm Situation, and Streaming. It then blends and transitions between these programmes seamlessly, without you touching a button.
The result is a hearing aid that just works. You don’t need to switch modes at a restaurant or turn something on when music starts playing. AutoSense OS 7.0 recognises the situation and optimises itself automatically. Higher Infinio models carry more programmes within this OS — the 90 and 70 both include a full suite from music to streaming speech — while the 50 Standard and 30 Essential operate with a reduced programme set.
SmartSpeech Technology: Four Pillars of Clarity
Phonak bundles four interconnected features under the SmartSpeech Technology umbrella, which operates across the Infinio 90 and 70:
- StereoZoom 2.0: Available exclusively on the Infinio 90, this creates an ultra-narrow directional beam when you need to focus on a single speaker in a very loud environment — like across a noisy dinner table.
- Dynamic Noise Cancellation: Present on both the 90 and 70, this actively reduces unwanted background noise in real time, improving the signal-to-noise ratio without making the environment feel “dead” or unnatural.
- Motion Sensor Hearing: A built-in motion sensor detects whether you are stationary or moving and adapts the hearing strategy accordingly. Walking in a busy street gets a different processing profile than sitting still in a meeting room.
- Roger Technology: Both models include integrated Roger Technology — Phonak’s industry-leading wireless microphone system. Pair a Roger On or Roger Select microphone and stream speech directly into your hearing aids from up to 10 metres away, even in severe noise.
Every Feature That Makes Life Easier
Speech Enhancer (Infinio 90 only) further improves soft speech clarity in quiet environments — the kind of gentle, close conversation that happens at home with family. Tap Control lets you answer calls, pause streaming, or activate your voice assistant with a simple tap on the hearing aid. SoundRelax softens sudden loud, impulsive sounds like a door slamming. DuoPhone automatically streams a phone call to both ears simultaneously for maximum clarity.
Real Ear Sound preserves the natural spatial hearing cues your outer ear provides, so sound localisation remains accurate. UltraZoom is a strong directional focus mode for very challenging listening environments. WindBlock reduces wind noise interference for outdoor activities. SoundRecover2 is Phonak’s frequency lowering technology that makes high-frequency sounds audible to those with high-frequency hearing loss. WhistleBlock eliminates feedback and whistling. Tinnitus Balance provides tinnitus relief sound therapy built directly into the device.
All models carry a 20-channel processing system for precise, fine-grained audiological tuning, and both the 90 and 70 are backed by a 3-year warranty — one of the best in the industry.
| AUDIOLOGIST’S NOTE The Phonak Audéo Sphere Infinio is not just about noise. SoundRecover2, WhistleBlock, and Tinnitus Balance make it a clinically complete solution for a wide range of audiological profiles — from mild high-frequency loss to moderate bilateral hearing impairment with tinnitus. |
Infinio 90 vs Infinio 70: Which Should You Choose?
Both are Sphere models. Both carry Spheric Speech Clarity. The differences come down to strength, exclusivity of features, and your daily lifestyle demands.

Our Verdict: A Genuine Generational Leap
After 25 years of fitting hearing aids in Delhi, our team at Fairfield Hearing Clinic is careful not to overstate new product launches. Manufacturers release incremental updates frequently and often describe them as revolutionary. The Phonak Audéo Sphere Infinio is genuinely different.
Spheric Speech Clarity solves a real problem that millions of people with hearing loss experience every day — the social isolation that comes from not being able to follow group conversations. By extending speech intelligibility to all directions rather than just the front, it gives wearers back a level of social participation that no previous hearing aid has matched.
The Infinio 90 is the right choice for anyone who lives an active social life and wants the best technology available. The Infinio 70 is an excellent choice for those who want Sphere AI with a sensible compromise on processing depth. Both carry Roger Technology, both have 20 channels, both have 3-year warranties — and both represent a meaningful step forward in what a hearing aid can do for you.

Frequently Asked Questions
Q: What is Spheric Speech Clarity and how is it different from regular noise cancellation?
Regular noise cancellation reduces background sound volume. Spheric Speech Clarity is an AI system that specifically identifies and enhances speech signals arriving from any direction — not just in front of you. It doesn’t just make things quieter; it makes speech clearer from every angle simultaneously. This is a fundamentally different approach to the problem of hearing in noise.
Q: Is the Phonak Audéo Sphere Infinio suitable for severe hearing loss?
The Audéo Sphere Infinio is available in multiple receiver strengths (S, M, P, UP) to cover mild to severe hearing loss. For profound hearing loss, Phonak offers separate power aid options. During a free hearing test at our Delhi clinic, our audiologist will assess your audiogram and recommend the exact receiver power level that suits your degree of loss.
Q: Does the Phonak Audéo Sphere Infinio work with Android phones?
Yes. The Audéo Sphere Infinio supports Bluetooth connectivity with both iOS (iPhone, iPad) and Android devices. Streaming, call handling, and control through the myPhonak app work across compatible Android smartphones. Check Phonak’s compatibility checker at phonak.com for your specific device.
