Abstract

The invention provides a voice data enhancing method and a system, wherein the method comprises: estimating an impulse response function in a far-field environment; filtering the near-field voice training data through the use of the impulse response function; and performing noise-adding process on the obtained data after the filtering to obtain the far-field voice training data. According to the invention, it is possible to avoid the problem that a large amount of time and economic cost are required to record the far-field voice training data in the prior art; and the time and the economic cost of obtaining far-field voice training data are reduced.

Description

【Technical field】 [0001] The present application relates to the field of artificial intelligence, in particular to a voice data enhancement method and system. 【Background technique】 [0002] Artificial Intelligence (AI) is a new technical science that studies and develops theories, methods, technologies and application systems for simulating, extending and expanding human intelligence. Artificial intelligence is a branch of computer science that attempts to understand the essence of intelligence and produce a new intelligent machine that responds in a manner similar to human intelligence. Research in this field includes robotics, speech recognition, image recognition, natural language processing and expert systems, etc. [0003] With the continuous development of artificial intelligence, voice interaction is increasingly promoted as the most natural way of interaction, and people's demand for voice recognition services is increasing. Smart speakers, smart TVs, smart refrige...
