Phonak’s Spheric Speech Clarity is the centre-piece of Audéo Sphere Infinio. Built on the dedicated DEEPSONIC™ neural-processing chip, it runs a 4.5-million-parameter deep-learning model that was trained on 22 million sound samples to recognise the difference between speech and every imaginable type of noise. As soon as AutoSense OS 6.0 flags a challenging scene, the DNN applies a frequency-by-frequency mask that lifts voices and removes interference, much the way your brain “locks on” to a conversation at a party.

In independent lab tests, this AI denoising delivered up to 10 dB better SNR and twice the likelihood of catching every word during complex group chatter compared with the same aids running without the feature, and up to 36 % more speech understood than two leading competitors. Because the algorithm works on signals arriving from all directions, you don’t need to keep the speaker squarely in front of you; head turns, side-talkers and circular dinner tables no longer derail the flow of conversation.

Spheric Speech Clarity is available in both Sphere performance levels, but with differing intensity: full strength in the i90 Sphere and medium strength in the i70 Sphere. In everyday terms that means premium wearers experience the maximum noise stripping the chip can muster, while advanced users still enjoy a substantial lift in noisy cafés, open-plan offices or family gatherings. Best of all, the process is automatic, no buttons, apps or manual programmes to fiddle with, so you can relax and stay present in every conversation, no matter how lively the room becomes.

The Calm Situation program is tailored for quiet environments, providing optimal gain settings for speech understanding and listening comfort during one-on-one conversations or solitary activities. Available across all Infinio models, this feature ensures that subtle sounds are amplified appropriately without introducing unnecessary noise. 

In tranquil settings like reading at home, engaging in a quiet conversation, or enjoying nature, the Calm Situation program maintains a natural sound quality. It preserves the nuances of speech and ambient sounds, allowing users to remain connected to their environment without auditory fatigue. 

By delivering a balanced listening experience, this program supports users in maintaining social connections and enjoying peaceful moments with clarity and ease. 

The Comfort in Noise feature actively reduces background noise when no speech is present, enhancing listening comfort in environments with constant ambient sounds. This program is particularly beneficial in settings like public transportation, busy streets, or open-plan offices, where background noise can be distracting. 

By suppressing non-speech sounds, the hearing aids allow users to focus on their tasks or thoughts without being overwhelmed by environmental noise. This reduction in auditory clutter contributes to decreased listening effort and increased overall comfort. 

Available in all Infinio models, the Comfort in Noise program seamlessly transitions between different listening environments, ensuring that users experience consistent comfort throughout their day. 

DuoPhone is a feature that streams phone call audio to both ears simultaneously, providing a 3.1 dB improvement in signal-to-noise ratio (SNR) during calls. This binaural streaming enhances speech clarity and comprehension, making phone conversations more accessible and enjoyable. 

By delivering the caller’s voice to both ears, DuoPhone reduces the cognitive effort required to understand speech over the phone, especially in noisy environments. This feature is particularly beneficial for individuals with hearing loss in both ears, as it provides a balanced and clear audio signal. 

Integrated into all Infinio models, DuoPhone supports users in maintaining personal and professional connections through improved telephone communication. 

The Music Programme is designed to deliver a rich and immersive listening experience for music enthusiasts. By offering an expanded dynamic range, slower compression, and additional gain, this program preserves the natural characteristics of music, allowing users to enjoy their favorite tunes with enhanced clarity and depth. 

Unlike speech-focused programs, the Music Programme minimizes processing that could distort musical elements, ensuring that instruments and vocals are reproduced accurately. This attention to fidelity makes it suitable for both casual listening and critical appreciation of music. 

Available across all Infinio models, the Music Programme enriches the auditory experience, enabling users to connect with music in a more meaningful way.

StereoZoom 2.0 is an advanced feature available in the I90 and I70 models, utilizing adaptive multi-channel beamforming to focus on the speaker directly in front of the user. This precise microphone focus enhances speech understanding in complex and noisy environments, such as crowded gatherings or busy streets. 

By dynamically adjusting the directional focus based on the acoustic environment, StereoZoom 2.0 provides a more natural and comfortable listening experience. It allows users to engage in conversations with greater ease, even when background noise is present. 

This feature exemplifies Phonak’s commitment to delivering innovative solutions that address real-world hearing challenges, supporting users in maintaining active and connected lifestyles.

Dynamic Noise Cancellation is a sophisticated noise-reduction algorithm available in the I90 and I70 models. It works in real-time to suppress surrounding noise without affecting speech clarity, enhancing the overall listening experience in various environments. 

By continuously analyzing the acoustic environment, this feature distinguishes between speech and noise, applying appropriate suppression to unwanted sounds. This selective reduction of background noise allows users to focus on conversations and important auditory cues. 

Dynamic Noise Cancellation contributes to reduced listening effort and increased comfort, supporting users in navigating complex auditory settings with confidence.

Tap Control is an intuitive feature in the I90 and I70 models that allows users to manage calls and streaming with a simple double-tap on the hearing aid. This hands-free control enhances convenience, enabling users to answer or end phone calls and play or pause audio without needing to access their phone. 

The feature utilizes motion sensors to detect tapping gestures, providing a seamless and responsive user experience. This functionality is particularly beneficial for individuals with dexterity challenges or those seeking a more discreet way to interact with their hearing aids. 

Tap Control exemplifies Phonak’s dedication to user-centric design, offering practical solutions that integrate seamlessly into daily life. 

Speech Enhancer is an adaptive algorithm that lives only in the top-tier Audéo Infinio Sphere I90. When the aids detect very soft speech – roughly 30-50 dB input with a clean signal-to-noise ratio of at least +10 dB – the feature selectively boosts the peaks of that speech by up to 10 dB. It does so without touching steady background sounds, so whispers, distant comments or softly spoken partners become clear while the room stays naturally quiet.

For users, the difference shows up in everyday situations such as bedside conversations, theatre intermissions or a quiet car ride where voices can otherwise fade away. Independent studies cited by Phonak report lower listening effort and a clear preference for Speech Enhancer when soft speech is present in quiet settings. Because it runs automatically inside AutoSense OS 6.0, there is nothing to press or switch, your Infinio i90 simply lifts the words you would most hate to miss.
