UnverifiedThe technical basis of voiceprint recognition is acoustic parameters such as vocal tract morphology and fundamental frequency features, which are considered individually unique, but voice cloning can bypass automatic voiceprint verification systems based on MFCC or deep embedding vectors.84% similarUnverified声纹识别技术从GMM-UBM、i-vector发展到x-vector（基于TDNN）和d-vector（基于LSTM），噪声条件下识别准确率显著提升76% similarUnverified该项目支持声纹识别和声音克隆功能73% similarUnverifiedMicrophone arrays use beamforming technology to calculate the direction of sound by leveraging the time difference of arrival (TDOA) of the same sound source received by each microphone, thereby focusing on the sound from the target direction and suppressing noise.70% similar
