Qualcomm Smart Audio Platform

Many audio manufacturers see the opportunities presented by the rapidly increasing demand for smart speaker products, however the process of developing a smart speaker that meets high consumer expectations can be complex and challenging - requiring the integration of an array of features and advanced capabilities. The Qualcomm® Smart Audio Platform is designed specifically to help reduce the time and streamline the process for developing smart and networked speakers, and offers manufacturers variety of choices to help them participate in the growing smart speaker opportunity.


The Qualcomm Smart Audio Platform is designed to bring together a powerful combination of processing, connectivity options, voice user interfaces and premium audio technologies, to help deliver a highly flexible, unique end-to-end single-vendor smart speaker solution. With our proprietary audio technologies integrated, the platform supports high resolution audio, whole-home networked audio, echo cancellation, beamforming, noise suppression and barge-in wake-word detection. It supports both Linux and Android Things operating systems, as well as voice services from major providers.
