Knowles Releases New Broad Market Development Kit to Speed up Voice Integration for Bluetooth Devices

Bluetooth Standard Solution Development Kit supports integration and includes Knowles Audio Processor, SDK, pre-integrated mics, and integration support for Bluetooth chips.

Knowles Corporation announced the AISonic Bluetooth Standard Solution, a complete development solution that enables ideal voice integration to Bluetooth devices. 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.  

AISonic Bluetooth Standard Solution is one development package available under Knowles’ new line of reference solutions for voice activation, control, and contextual audio processing for TVs, portable speakers, soundbars, whitegoods, and a range of IoT electronics, known as Knowles Industry Standard Solutions. The kit is built upon Knowles' AISonic Audio Edge Processor IA8201, which achieves suitable performance along with, per the company, the industry’s lowest power consumption to enable wake-on-voice functionality in small, battery-operated devices.

The AISonic Bluetooth Standard Solution Package balances scalability and flexibility to bring ease of integration across embedded platforms. The kit features an 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 to enable the highest quality audio capture. The solution has helped Knowles partners to scale further in developing AWS-AVS, Alexa Auto and AVS-AMA solutions on several Bluetooth and embedded MCU platforms.

The opportunities for voice integration have extended from inside homes and buildings to mobile, automotive, wearable, and other accessory applications for on-the-go control. Sugr, a world-wide solution provider well known for its voice algorithm and integration capability has just completed the iOttie Aivo Connect integration with Knowles IA8201.

The AISonic Bluetooth Standard Solution also includes algorithms for an Audio Front End suitable for use with many voice assistants or cloud-based 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 stringent false wake standard of AVS.

Retune DSP is part of the Knowles OpenDSP ecosystem and 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.

The AISonic Bluetooth Standard Solution is now available to customers.
