Product introduction:
1 ➢ Based on the dual microphone directional pickup and deep learning noise reduction algorithm,the real-time separation of target voice and background noise can extract clear voice, with a noise suppression performance of up to 30dB in a variety of noise scenes, which greatly improves the speechinteraction effect of AI products in more noisy scenes. It is a leader in the industry.
2 ➢ Home environment 3 ~ 5m far-field pickup, high-precision identification, fast response, USB2.0 standard protocol scheme module and interface.
3 ➢Realize the real-time separation of human voice and background noise and extract clear human voice, so that users can experience clear and smooth audio and video calls even in a strong noise environment.
4 ➢ noise reduction solution: noise reduction microphone, active noise reduction, separation of human voice and background sound to realize effective long-distance speech recognition, with adistance of about 3-5M.
5 ➢ Based on noise reduction and beam azimuth algorithm, sy6228C USB outputs independent
4-channel digital microphone to pick up audio in digital audio PCM format, which can open noise reduction and dmic gain settings and support secondary development, so as to provide corresponding array signal processing algorithm module on the host side on Android / Windows / Linux, based on signal azimuth estimation, signal noise reduction and enhancement, etc.
