The MT8516 two-mic development kit for Alexa Voice Service (AVS), says the company, aims to help developers build high-quality voice-assistant products, reducing development costs, and accelerating the integration process for creating far-field products with Alexa built-in, including multi-room music (MRM) capabilities.

“As the No. 1 chipmaker for voice assistant devices, MediaTek is at the forefront of the connected device revolution, powering some of the most innovative voice recognition products in homes today,” says Jerry Yu, MediaTek Corporate Senior Vice President and General Manager of the Intelligent Devices Business Group. “The MT8516 development kit accelerates the development of devices with voice technology, making it easier for developers to bring consumers smart speakers, soundbars and other home appliances with the latest features.”

The kit is offered as an integrated hardware and software solution ideal for a wide range of voice assistant devices and audio applications. It features a quad-core ARM Cortex-A35 application processor operating up to 1.3 GHz, both Wi-Fi and Bluetooth capabilities built in, and integrated audio front-end and post-processing technologies.

With MT8516, says the company, audio manufacturers can reduce the development time, effort, and costs associated with designing and customizing smart speaker products. Manufacturers can integrate the MT8516 into a range of smart devices including speakers, sound bars, smart home hubs, industrial applications, and smart home appliances.

The platform is capable of the following technology components, which are included with the kit (license for each technology required):

  • AVS Device SDK: With C++-based libraries, manufacturers can easily design devices that process audio inputs and triggers, establish persistent connections with AVS and handle all Alexa interactions.
  • Amazon multi-room music (MRM): Enables developers to design smart products with MRM so customers can enjoy simultaneously streaming music over multiple Alexa built-in devices.
  • MediaTek far-field algorithms: Integrating the algorithms on the application processor saves costs by eliminating the need for an additional digital signal processor (DSP). Qualified by Amazon with a two-microphone linear array, MediaTek also offers a four-microphone circular arrangement for added design flexibility.
  • Amazon wake-word engine (WWE): Provides robust wake-word recognition in Alexa supported locales.
  • MediaTek PowerAQ: MediaTek’s acoustic tuning tool PowerAQ provides an easy-to-use graphical user interface (GUI) for signal flow design and audio parameter turning.

The MT8516 reference solution is featured on Amazon’s Alexa developer portal.
