What if your fridge warned you before it broke? Well, now it’s possible.
Imagine if your refrigerator hears a subtle vibration, predicting failure before it happens. Your oven guides you by the sound of your food sizzling. A health patch silently monitors your breathing patterns, alerting you to irregularities in real-time.
This is not science fiction. This is the sign of a new era, where audio drives intuitive, human-centric interactions between people and devices.
Audio as the interface: Beyond buttons and screens
Voice is the most natural interface we have ever known. Unlike traditional inputs, speech allows us to interact hands-free and eyes-free. This makes the technology ideal for daily tasks like cooking, driving, or assisting those with disabilities.
But to make this seamless and personal, technology needs more than a microphone. The solution demands:
- Persistent and ultra-efficient audio processing
- Robust AI, engineered to work together at the edge
Power and Performance — The Technology Behind Always-On Audio
Always-on audio relies on ultra-low-power architectures designed to listen continuously without draining energy. Modern microcontroller platforms now integrate autonomous analog subsystems capable of monitoring and pre-processing sound while operating in deep-sleep modes, enabling persistent listening with minimal power consumption.
Arm Cortex-M55
At the processing core, the Arm Cortex-M55 with Helium DSP extensions delivers significantly higher performance for embedded audio tasks—providing up to three times the efficiency needed for real-time signal processing, noise suppression, and on-device inference.
Neural Network Acceleration
Dedicated neural network accelerators further enhance these systems by offloading compute-intensive functions such as wake-word detection and voice activity recognition. This makes continuous listening feasible even in compact, battery-powered devices—from wearables to distributed IoT sensors—while maintaining fast response times and efficient power usage.
Intelligence – Software brings audio to life
DEEPCRAFT AI Suite is the engine behind transformative audio experiences. DEEPCRAFT Voice Assistant solution brings the following features, optimized for low-power Infineon MCUs:
- Accurate voice commands
- Custom wake words
- Keyword recognition
Speech-to-intent AI offers best-in-class performance with high accuracy and minimal false detects, while supporting both native and non-native English speakers.
DEEPCRAFT Audio Enhancement cleans up noisy environments with robust AI techniques:
- Noise suppression
- Acoustic echo cancellation
- Dynamic beamforming
These features are calibrated with easy-to-use tools for rapid integration. Developers can build, test, and deploy voice models via a no-code graphical UI, ensuring faster product development.
Integrated innovation – Affordability meets sophistication
Where once only expensive devices could offer clarity and smart voice recognition, PSOC Edge brings advanced edge audio to everyone.
Its built-in DSP capabilities and audio front-end middleware mean complex processing. From multi-mic beamforming to acoustic event detection, all happens within a single, efficient platform.
Furthermore, DEEPCRAFT’s AI-driven enhancements extend these advantages to cost-sensitive products like entry-level earbuds or low-cost smart sensors. This ensures everyone gets premium experiences.
Your next device, powered by Infineon audio innovation
With traditional solutions, advanced features like real-time voice and sound recognition have required expensive hardware or deep dependence on cloud-based computing. This limitation made them inaccessible to lower-end devices.
The synergy of PSOC Edge hardware and DEEPCRAFT software enables even resource-constrained devices to truly hear, understand, and act—all in real time, on ultra-low power, and with human-like intuition.
This breakthrough makes previously exclusive, cloud-dependent features available across a broader range of devices, democratizing intelligent functionality. Infineon is committed to building interfaces that empower people through natural, voice-driven interaction.
Takeaway
From predictive maintenance to voice-guided cooking, smart audio is reshaping how we live. Infineon’s integrated hardware and software make this transformation accessible to all, enabling high-quality, always-on audio experiences.
