Product Description
The LHT-ARRAYMIC-GG4 integrates multi-microphone array technology, DNN, AGC, AEC, AES, ASR, and other algorithm technologies. Plug-and-play functionality allows for rapid product intelligent transformation.
Multi-channel microphone audio, using DSP-based algorithms such as echo cancellation, sound source directionality, beamforming, and noise reduction, eliminates device playback and suppresses ambient noise.
DSP-processed audio can be output upstream via a USB audio port. The processed mono 16k 16-bit audio is used for voice wake-up and recognition. Compact in size (32mm x 20mm), it's easy to install and plug-and-play, allowing for rapid product intelligent transformation. It supports multiple functions, including audio and video calls, audio recording forensics, voice recognition, and menu navigation. It is suitable for various industries, including conferencing, education, and finance.
