Long-Distance Pickup

Supports 3-5m range pickup, omnidirectional pickup direction.

Voice Processing

• Two PDM microphone inputs
• Digital Signal Processing pipeline
  • Full duplex, stereo, acoustic echo cancellation (AEC).
  • Auto batch delay insertion feature (ADEC) with reference audio through I2S
  • Point noise suppression by interference canceller (IC)
  • Switchable fixed noise suppressor (NS)
• Programmable automatic gain control (AGC)
• Separate audio paths for Communications (Comms) and Automated Speech Recognition (ASR)

Device Interface

• Full-speed USB 2.0 compatible device, supporting USB audio class (UAC) 1.0
• USB HID and endpoint 0 control interfaces
• Flexible peripheral interface
  • Programmable digital general inputs and outputs
  • I2C interface for system control and local peripheral control
  • I2S slave interface input and output audio data
  • SPI master interface for control and inquiry of local SPI slave devices

Firmware Management

• Option to boot from QSPI flash
  • Default firmware image for power-on
  • Firmware image updates provided over USB
  • Fixed user data during firmware upgrade cycles
  • User-configurable programming for SPI peripherals
• Option to boot via SPI from local host processor
• Device firmware updates over I2C or USB (DFU)

Application

As a cost-effective voice interface solution for smart devices, not only may it be necessary for Automated Speech Recognition (ASR) applications, but it could also be used for voice calls (Communication); it is particularly optimized for ASR front-end processing, greatly improving performance in voice interrupt and recognition capabilities. Given its comprehensive features, the following or similar smart devices are recommended for its application:

• Navigation robots (ASR)

• Medical equipment (ASR)

• Fitness equipment (ASR)

• Large-screen advertising machines (ASR)

• Lecture streaming (Comms)

• Camera microphones (Comms)

• Smart speakers (ASR)

• Conference treasure (comms)
