Even in environments where the surrounding noise makes it difficult to have a normal conversation, the FR-1100 with its noise canceling function allows one to clearly collect exchanges with customers.

Furthermore, the output signal as stereo enables simultaneous recording from 2 different directions, and allows distinctive and independent speech analysis on each channel, i.e., for each participant.

Overview

The FR-1100 is a solution suite developed by NTT-AT based on integrated microphones' array (HW) and intelligent audio processing library (SW) first developed by NTT R&D laboratories and currently distributed by NTT Technocross Corporation. It enables one to extract specifically voice signals from 2 directions independently (2-participants conversation) despite strong surrounding noises, and provide clear stereo output signal for optimized speech-to-text and any other post-processing. 

FR-1100 Features

• A pocket-size and highly directional microphone that leverages audio processing technology developed at NTT Research & Development Laboratories to isolate voice signals from two directions simultaneously
• Changing the mic settings allows one to collect voices from various directions and fit multiple potential use-case requirements.
• High quality noise cancelation function, without degrading the human voices signals
• The collected sound source can be transferred to an external device (recording system, computer, tablet, etc.*) using either a USB cable or an analog cable (stereo mini plug cord).
• Power supply using USB bus power method
• The LED lighting on the top allows one to check the direction in which sound collection is detected.
• Palm-sized, lightweight (~61g) and easy-to-carry solution for on-the-spot recording anywhere

Use-cases

Ideal for situations where one wants to collect clear voice signals despite noisy environments:
