AISonic™ IoT Development Kit

Add Voice and ML to Practically Anything

Introducing AISonic™ Raspberry Pi Development Kit

Knowles AISonic™ IA8201 Raspberry Pi Development Kit brings voice, audio edge processing, and machine learning (ML) listening capabilities to devices and systems in a range of new industries. This kit gives product designers and engineers from OEM/ODM companies a single tool to streamline design, development and testing of technology to push the boundaries of voice and audio integration in their respective industries.

Enables wake-on-voice processing for low latency voice UI, noise reduction, context awareness, and accelerated machine learning inferencing for edge processing of sensor inputs.

AISonic™ Audio Edge Processor IA8201 is a high-performance, ultra-low power audio-centric Open DSP supporting up to 4 mics, multiple high speed interfaces and GPIOs in two package options.



Open DSP

This Knowles partner program brings world-class algorithm and cloud contributors to an ecosystem where a multitude of solutions solve complex audio problems.

Highly Optimized Advanced Instruction Set

The DSP SDK (Software Development Kit) with Knowles and Xtensa HiFi 3 instruction sets enable extensive audio capabilities for voice and audio processing, voice user interface and ambient sound processing.

Multi-core Audio Processing

Two Tensilica-based, audio-centric DSP cores; one for high power compute and ML, the other for very low power always-on processing of sensor inputs.


Low Power Voice Wake: Listens for specific OEM keywords to wake the host processor. Large memory enables processing of multiple stages on-chip for accurate results.

Proximity Detection: When combined with an ultrasonic capable speaker and microphone, detects the distance between the system and an object; can replace an IR-Prox sensor in bezel-less phones.

Hub: Determines location of voice source while tuning out a noisy environment and lowering music to detect voice commands. Simultaneously takes metadata input and overrides beamformer to focus on camera-tracked objects.

Security System: Activates with a voice command. Detects glass breakage/smoke-alarm, logs direction of noise source, triggers alarm and sends alerts through WiFi connection.
