The new AS3xx series of Smart Edge AudioSmart solutions, says the company, are designed to enable secure intelligence at the edge for privacy and superior user experience. For example, the AudioSmart AS371 targets a broad variety of voice-enabled smart home devices including hubs, Wi-Fi repeaters, speakers, and appliances, and incorporates a new machine learning engine using the company’s SyNAP (Synaptics Neural Network Acceleration and Processing) technology.

SyNAP enables advanced features such as user identification and behavioral prediction, which allows voice assistants to perform ambient computing and a more intuitive interaction with users. In addition, with SYNAP on-device intelligence, the AS371 enhances consumer privacy by greatly reducing the need to continuously send personal data to the cloud. SyNAP also takes the right steps to support GDPR compliance as well as other current and emerging regulations.

“Intelligence at the edge begins in the smart home where privacy is paramount and with voice as the fastest growing and most natural human interface,” says Huibert Verhoeven, senior vice president and general manager, IoT Division, Synaptics. “Adding to our established market-leading position in voice, our new cutting-edge voice processing technology designed using a 22nm process node, along with our innovative SyNAP integration, not only provides unmatched performance and security, it also opens numerous new opportunities across consumer IoT products spanning speakers, displays, set-top-boxes, thermostats, lighting, Wi-Fi repeaters, home appliances and much more.”

The AudioSmart AS3xx family also introduces the company’s fully integrated and purpose-built far-field voice processing and wake word technology. Through in-house design of the SoC, wake word engine, voice pre-processing and playback enhancement, the company says it has optimized the complete system to achieve the highest possible far-field voice performance at affordable consumer electronics price points.

In addition, says the company, by providing the complete solution including acoustics system expertise, it greatly reduces the time-to-market for smart home product manufacturers and allows them to add a voice-first experience while maintaining focus on their core expertise. Further, Synaptics’ AS3xx solutions are fully compatible with all voice assistant platforms worldwide.

The new AS3xx products include the following:

  • AS371 (for voice-enabled devices with SyNAP)
  • AS390 (for voice-enabled devices with displays)
  • AS350 (for voice-enabled low-power devices)
  • AS320 (for voice-enabled microcontroller-based devices)

The AudioSmart AS371 is sampling now. The other devices are expected to start sampling sometime in the first quarter.
