Product Description
iFLYTEK microphone array is designed as circular 6-microphone board. Ingenious design helps to achieve 360° sound pickup and 1° wake up resolution. Original and noise-reduction audios, wake-up angle and main microphone number all can be obtained. Moreover, user can set main microphone and light.
Microphone array is an acoustic system that uses multiple acoustic sensors(microphones in general) to sample and process spatial characteristics of sound field.
Function: locate sound source, suppress background noise, interference, reverberation and echo, extract and separate signal, etc.

Product Features
Product Features
Determine Sound Source Location and Azimuth
Based on TDOA(Time Difference Of Arrival) algorithm, microphone array calculates angle and distance of sound source from it, so that target sound source can be tracked.
Support Echo Canceling
Read and process echo through reference signal interface to cancel echo.
Show Sound Source Direction with LED
Microphone array has 12 LED lights which light up to show the direction of sound source. User interaction experience is highly improved.
Support Text to Speech (TTS)
Apply to Robot Voice Control and Voice Navigation
