AudioSmart® DS20924

The DS20924 AudioSmart 4-Microphone Development Kit for Amazon AVS features Synaptics' CX20924 Voice Input Processor running Synaptics' far-field Smart Source Pickup (SSP) voice processing technology, Smart Source Locator™ (SSL) that detects the direction of a user, and is preloaded with Alexa wake word. Synaptics' far-field voice input processor focuses on the user’s voice and removes echoes and noise from the audio signal, providing clear voice requests for speech recognition processing.
