AI Speech M12 Pro

Overview

AIMIC-M12 Pro is a 360° noise-canceling conference microphone speaker designed specifically for enterprise conference rooms by AISPEECH. It is an intelligent conference microphone speaker that combines sound collection, sound amplification, speech transcription, and subtitle simultaneous transmission. The product uses a 12-element omnidirectional microphone array and achieves 5-meter radius omnidirectional sound collection, intelligent noise reduction, echo cancellation, real-time speech transcription, and other functions through audio algorithms. It solves the conference pain points such as unclear remote calls, noisy environments, and difficulty in organizing meeting minutes for users. The built-in high-fidelity speakers enable users to hear clearly and maintain efficient communication. With the support for cascading up to five units, this product can achieve a wider sound collection range and can be deployed in larger conference rooms.

Applicable scenarios: Conference rooms of various sizes.

Features

12-Mic 360° Pickup

• With a circular array of 12 omnidirectional analog MEMS mics, M12 delivers stable 360° pickup with strong noise immunity. In typical conference rooms, one unit covers about a 5 m radius, suitable for meetings of around 10 people. In rooms with better acoustics, the pickup radius can extend to approximately 8 m, so distant participants are still heard clearly without raising their voices.

Smart Voice Enhancement

• M12 uses intelligent voice locating and Automatic Gain Control (AGC) to track the active speaker and adjust gain within a 5 m radius. As people move or change seats, the output volume remains consistent and natural. Human voices are prioritized and enhanced while preserving detail, ensuring clear speech even near the edge of the 8 m extended pickup range.

Deep Noise & Echo Control

• By learning typical conference-room noises, M12 can suppress up to 95% of background noise with a noise reduction depth of up to 35 dB. Air-conditioning hum, keyboard typing, and chair movement are significantly reduced so speech stays clean and natural. A separated mic–speaker design plus intelligent echo cancellation and reverb suppression help eliminate howling and echo, so remote participants hear a clear, easy-to-follow voice signal.

5-Unit PoE Cascade Deployment

• Up to five M12 units can be cascaded over PoE in a star topology, synchronizing pickup and playback in real time. This enables flexible deployment: one unit for small rooms (up to ~10 people), two units for medium rooms (10–20 people), and up to five units for larger spaces with more than 20 participants. The result is even coverage from the center of the table to the corners of the room, ensuring reliable audio for meetings of all sizes.

HiFi Sound & Full-Duplex Calls

• M12 integrates two 8 W high-performance speakers with an optimized bass chamber to deliver powerful, comfortable HiFi sound in a compact form. Music mode offers a 100 Hz–20 kHz frequency response, while voice mode is tuned to highlight vocals for better intelligibility. With loudness up to about 85 dB, it easily covers small and medium conference rooms. Full-duplex audio lets both sides speak and interrupt freely without clipping, creating a natural, in-person conversation experience.
