The AISonic Bluetooth development kit includes the Knowles Audio Processor, an SDK, pre-integrated mics, and integration support for Bluetooth chips. The development kit enables OEM and ODMs to build voice-activated calling, control, and far-field speech recognition capabilities into Bluetooth devices, including smart speakers, smart home locks, connected light switches, wearables, in-vehicle voice assistants, and more.

The kit is built around the AISonic Audio Edge Processor IA8201, which enables wake-on-voice functionality in small, battery-operated devices.

The kit features the IA8201 reference board accompanied with an API supporting integration with Bluetooth chipsets having an embedded MCU running an RTOS, and system firmware release configured to support sensors and pre-integrated microphones from Knowles. Sugr, a developer with its own voice algorithm and integration capability, has just completed the iOttie Aivo Connect integration using the Knowles IA8201 board.

The AISonic Bluetooth devit also includes algorithms for an audio front end suitable for use with many voice assistants or cloud-based automatic speech recognition (ASR) APIs. The Knowles OpenDSP partner program allows for many algorithm developers to provide libraries for a beam former, omnidirectional voice capture, AEC to sort voice commands from background to meet the false wake standard of AVS.

Retune DSP has ported its voice-control solutions, VoiceSpot and VoiceSeeker to the IA8201. VoiceSpot, Retune’s ultracompact wake word engine, enables voice-wake on memory-constrained, always-on, battery operated edge devices, and is Amazon-certified. VoiceSeeker is Retune’s multi-microphone audio front-end preprocessing solution capable for far-field voice control applications. Furthermore, Retune’s Conversa two-way voice communication software solution enables the IA8201 on a number of high-performance Bluetooth speakerphones and headphones.

“We’ve leveraged Knowles’ audio and voice integration expertise to create a powerful suite of standard solutions for different applications to make it easier for manufacturers to quickly and efficiently add speech recognition and voice capabilities to devices and get to market in a fraction of the time,” said Vikram Shrivastava, senior director, IoT Marketing at Knowles, in a statement.

The AISonic Bluetooth standard solution is now available to customers.
