Hands-Free TV Voice Control with Dual Microphone Array
To support completely hands-free TV voice control and search, Li Creative Technologies (LcT) has developed a dual microphone array solution for robust voice capture. A user utters voice commands directly at the TV from a distance of 4 meters away, and our solution cancels TV sound and background noise and outputs clean speech for speech recognition. Consequently, a user does not need to mute the TV nor talk into a remote. [Listen to Audio Demo]
LcT’s solution utilizes advanced audio signal processing, including far-field microphone array, adaptive beam forming, adaptive sound cancellation, and noise reduction. We integrate a two-sensor microphone array with our DSP algorithms. Our technology can improve speech recognition accuracy from 0% to over 90% when the TV sound on.
