Development kit accelerates Amazon Alexa designs

A variant of the Synaptics AudioSmart 2-Mic Development Kit for Amazon AVS has been released by Arrow Electronics, Synaptics and NXP Semiconductors. It is supported by a commercially available NXP system-on-chip (SoC) application processor.

This newly available development kit variant enables device makers to quickly and cost-effectively integrate the Amazon Alexa Voice Service (AVS) into a fully functioning prototype, and then take that work into design for manufacturing and production. 

The Synaptics AudioSmart 2-Mic Dev Kit for Amazon AVS includes Synaptics’ CX20921 Voice Input Processor with a dual microphone board and a wake-word engine tuned to "Alexa."

It is built on the pico-imx7d board, a purpose-built small-footprint hardware platform which features NXP’s i.MX7D dual-core applications processor optimised for the internet of things (IoT).

The kit also includes: stereo microphones with an integrated processor, a microphone holder board, a micro USB cable, Type-A to Type-B cable, cable assembly and a +5V power supply. 

The development kit features a reference client built using the AVS Device SDK (software development kit), enabling commercial device makers to get to market faster with Alexa-enabled products. 

“This new Synaptics development kit with an NXP SoC for the Amazon Alexa Voice Service can add intelligent voice control to connected products with a microphone and speaker, enabling developers and engineers to rapidly create Alexa-enabled proof of concepts and prototypes,” said Murdoch Fitzgerald, vice president of semiconductor marketing at Arrow.  

“Voice as a human interface is rapidly expanding in smart homes and the broader IoT landscape due to the broad global expansion of voice services like Amazon Alexa,” added Saleel Awsare, vice president and general manager, Audio and Imaging Business, Synaptics. “When voice services are combined with Synaptics’ AudioSmart far-field voice DSPs, new voice-enabled human interface devices can accelerate into numerous IoT applications whether consumer, enterprise, or commercial.” 

“Industry leaders are developing and investing to meet the growing demand of the voice-controlled future smart home,” explained Martyn Humphries, vice president and general manager, Media IoT and i.MX Applications Processors at NXP. “Collaborating with leaders like Amazon and the companies it works with is essential in delivering the key tools and support needed to meet the demands of this prospering market. The new evaluation kit moves beyond the scope of a processing board with unique integrated features designed for the AVS developer community. This enables more flexibility in designs while shortening development time to market so customers can move from prototype to production as quick as possible.”
