0 57

Dusun Electron Ltd. will be demonstrating its far-field voice control solution at the 2019 Consumer Electronics Show held in Las Vegas. This new voice control solution enables voice-activated devices to clearly capture voice commands from a distance or even in noisy environments for a hands-free interactive experience.

Far-field voice control is becoming an important technology in AI human interaction for numerous applications such as smart TVs, smart speakers, Internet of Things (IoT) in smart homes (gateway, smart home appliances, etc.), wearables, digital health, robotics, and automotive infotainment. This voice control with hands-free capabilities uses a microphone array to capture the voice input from multiple directions at a specific distance, and the voice data is enhanced by various voice algorithms such as beamforming, echo-cancellation, and noise reduction to generate a clear signal used in the automatic speech recognition (ASR) engine.

Dusun’s far-field voice control solution focuses on voice input technology including the customizable microphone array designed for optimized performance and cost, a voice module that is fully integrated with multi-microphone interfaces, an ARM-based processor, voice front-end processing algorithms including sound localization (SL), noise reduction (NR), deliquesce reverberation (DR), acoustic echo canceller (AEC), automatic gain control (AGC), and beamforming (BM) to produce clear and high-quality voice data. This solution is also integrated with many leading ASR engine providers from Amazon’s Alexa, Google Voice, Microsoft’s Cortana, Baidu, and iFlytek for a complete voice control and recognition solution.
