CX20921 - Far Field Voice Input Processor SoC

Datasheet Summary

Description

The CX20921 is a high-performance, far field voice input processor System-on-Chip (SoC).

The CX20921 is the first product in this category with an integrated voice trigger function that supports a low system power Wakeon-Voice (WoV) function.

Features

  • Low-power WoV mode with an embedded third-party speech recognition engine.
  • Enables high-performance Automatic Speech Recognition (ASR) and excellent voice clarity with only two microphones through Conexant's AudioSmart voice input processing software, which includes:.
  • SSP noise suppression.
  • Full-duplex AEC.
  • Compatible with multiple leading embedded and server-based speech recognition vendors.
  • Dual far field, 24-bit, 106dB dynamic range ADCs.
