PRODUCT

The iSpeaker A20 is a professional-grade USB speakerphone designed for video conferencing and other communication scenarios. With its advanced AI noise reduction algorithm, 4+2 digital microphone array, and high-fidelity speaker, the A20 delivers clear, natural sound in any environment. Its sleek aluminum body and tidy cable management make it a perfect fit for any conference room.

Features

4+2 Digital Microphone Array : Equipped with four high-SNR microphones and built-in AI beamforming algorithm to precisely locate the source of sound. A20 host speakerphone is equipped with four high SNR(Signal to Noise Ratio) microphone array, with the built-in AI beam forming algorithm, can precisely locate the source of the sound. Two satellite microphones can enhance the the voice pickup range for larger room use, the max voice pickup range could be 100 ㎡.
Exquisite Design : Sleek aluminum body with silvery painting for a professional look. Aluminum body with silvery painting,delicate and fit the conferencing scenario.
Next Generation AI Noise Reduction: Advanced AI audio algorithm effectively eliminates background noise for clear communication. In the video conferencing scenario, there are various background noise when we are speaking,
like the mouse clicking, knocking, fan, typing and etc.). A20 adopts the advanced AI audio algorithm, can effectively eliminate the background noise and ensure a clear communication.
Plug and Play : Minimal configuration allows for quick deployment of the conferencing system. With the minimal configuration,plug and play, allow user to quick deploy the conferencing system. Tidy cable management, away from the messy desk.
Professional Acoustic Design: High-fidelity acoustic sound box with well-tuned tweeter and woofer units for clear, natural sound. A20 is equipped with a professional high-fidelity acoustic design sound box, with well-tuned tweeter and woofer units, can deliver clear, natural sound.
New generation AI Echo cancellation
The A20 is equipped with an echo cancellation system that combines traditional signal processing as well as the latest deep learning network (CrossNet). In order to improve the generalization ability of the system and ensure the subjective hearing and speech recognition, the R&D team uses a large amount of voice data to take into account the subjective hearing and speech recognition accuracy to ensure A20 audio performance.Now the near end single talk sound quality, far end single talk echo cancellation, double talk sound quality and Echo cancellation, speech recognition accuracy and other indicators have reached the industryleading level.
