Chinese artificial intelligence startup iFlytek says it has developed AI-powered technology that can accurately identify a person by his or her voice, for use in law enforcement. The company expects to be able to roll out a voiceprint recognition system nationwide in two to three years, said Fu Zhonghua, the deputy head of iFlytek's research center here. The Chinese market for such technology has the prospect of becoming a driver of earnings growth for iFlytek, which has been hit with U.S. sanctions for its alleged role in China's internationally criticized treatment of Muslim minorities. "Because recordings are important evidence when it comes to phone scams, demand for voice recognition is growing," Fu told reporters at the lab. The voiceprint recognition tool harnesses iFlytek's strength in using AI to analyze data.
