AcuEdge™ ZLK38AVS Development Kit for Amazon Alexa Voice Service (AVS) now introduces far-field voice pick up and the flexibility to build devices with multiple mic array configurations. The solution reduces BOM costs while addressing the requirements of small-form-factor designs.
As a leading audio front-end development kit with one-mic hands-free and two or three-mic far-field configurations qualified by Amazon, the solution features the ZL38063 audio processor which includes a 300 MHz DSP and dedicated hardware accelerators for voice processing. It also features Stereo Acoustic Echo Cancellation (AEC), which enables barge-in recognition to improve the consumer experience in extreme audio playback environments.
With the flexibility to work with a variety of microphone options and configurations, Original Design Manufacturers (ODMs) and third-party developers can use the development kit to cost effectively achieve their design criteria across a range of applications and form-factor constraints.
- home automation controllers
- set-top boxes,
- One-mic configuration – Offers hands-free voice coverage for products where form-factor or cost constraints preclude the use of a multi-microphone array
- Two and three-mic linear (180-degree) configurations – Designed for sound bars, smart plugs and switches, set-top-boxes or other applications typically positioned against a wall that benefit from 180-degree far-field coverage
- Three-mic triangular (360-degree) configuration – Also with far-field coverage qualified by Amazon, this configuration is well suited for applications that may require user interaction from any direction such as portable speakers, wide-angle IP cameras and voice-enabled Wi-Fi® routers
