Voice control is hot. Witness Amazon Echo and Google Home. These products work because they’re designed to recognize the spoken word from a distance—far-field speech recognition. It’s a useful capability in a wide range of consumer, medical, and industrial applications and SoundAI now has a kit you can use far-field speech recognition to differentiate your next system design whether it’s a smart speaker; an in-vehicle, speech-based control system; a voice-controlled IoT or IIoT device; or some other never-seen-before device. The SoundAI 60C MicA Development Kit employs FPGA-accelerated machine learning and FPGA-based signal processing to implement advanced audio noise suppression, de-reverberation, echo cancellation, direction-of-arrival detection, and beamforming. The FPGA acceleration is performed by a Xilinx Spartan-6 SLX4 FPGA. (There’s also an available version built into a smart speaker.)

The SoundAI MicA Development Kit’s circular circuit board measures 3.15 inches (80mm) in diameter and incorporates 7 MEMS microphones and 32 LEDs in addition to the Spartan-6 FPGA. According to SoundAI, the kit can capture voice from as far as 5m away, detect commands embedded in the 360-degree ambient sound, localize the voice to within ±10°, and deliver clean audio to the speech-recognition engine (Alexa for English and SoundAI for Chinese).
