Smart Audio 400 Platform

Designed to bring together the building blocks for developing a smart speaker in a single, flexible platform that helps reduce product development time and complexity.

The Qualcomm® Smart Audio 400 Platform is designed to combine superior sound quality, artificial intelligence (AI), and connectivity to help deliver advanced voice UI, great audio experiences, cutting-edge power management, and support cloud-based smart assistant services.

This end-to-end smart speaker solution is built around our Qualcomm® QCS400 series system-on-chip (SoC) with an on-board Qualcomm® Artificial Intelligence (AI) Engine, dedicated specifically for low-power, high-performance smart audio applications.

The Smart Audio 400 Platform supports Qualcomm® DDFA™ amplifier technology, Qualcomm® aptX™ Adaptive audio, up to 12-channel audio processing, as well as scalable connectivity solutions for low-latency multi-channel audio streaming throughout the home.

Enhanced voice assistance capabilities include low-power, always-on voice activation, simultaneous multi-keyword detection, multi-channel echo cancellation and local automatic speech recognition, as well as voice services from major providers.

To further streamline and simplify smart speaker development, the Qualcomm Smart Audio 400 Platform is available in the form of a development kit, which includes external speaker casing, bi-amped, two-way speakers, and a six-microphone array board as well as multiple other components in a reference design to help developers more quickly scope and design a product.

Qualcomm Smart Audio 400 Platform is a product of Qualcomm Technologies, Inc. and/or its subsidiaries.

Integrated single-vendor platform
