Qualcomm QCS-403 Audio SoC
Designed specifically for smart assistants, small form factor smart speakers and audio-capable home hub applications with an integrated, advanced Voice UI.
The Qualcomm® QCS403 System-on-Chip (SoC) is designed to bring new capabilities and smart functionality to lower-tier smart speakers and smart assistants.
QCS403 is part of our Qualcomm® QCS400 series of dedicated audio SoCs based on our high performance, low-power architecture. This SoC is designed to significantly reduce overall BOM for feature rich, voice-supported home audio products at a lower consumer price point.
