The Amazon Premium Far-Field Evaluation Kit is designed to help commercial device manufacturers enable high quality far-field voice experiences in their products. This development kit gives manufacturers access to the same leading-edge audio technology that powers Amazons’ Echo© devices. It features an advanced 8-mic rectangular array for devices that are primarily used from one direction, such as devices with a display or placed near a wall. This solution incorporates Amazon’s proprietary software and algorithm technology for “Alexa” wake word recognition, beam forming, noise reduction, acoustic echo cancellation, and barge-in capabilities.
The Evaluation Kit includes a rectangular microphone array board, an Intel digital signal processer board which contains the audio processing hardware to optimize the quality of the voice signal, and a NXP Pico-Pi i.MX 7D board to execute the AVS Client Application software. All the audio processing and wakeword trigger software, drivers, and sample AVS Client Application is available via download.
