Problems solved by technology

[0004] However, since the energy in the signal input by the user may come from the user's voice, it may also come from noises such as industrial production and transportation in the environment; if there is noise when the voice data is extracted, the noise will be extracted as voice data , resulting in inaccurate speech recognition

Abstract

The invention discloses a voice data extraction method and a voice data extraction device, relates to the field of voice identification and aims to solve the problem of inaccurate voice identification in the prior art. The technical scheme disclosed by the embodiment of the invention comprises the following steps of: acquiring an average noise value of the environment in which a voice device is positioned; after a user starts the voice device, segmenting a signal input by the user according to preset time to obtain at least one signal segment; and acquiring voice data from the signal input by the user according to the relation between an average audio value and the average noise value, which corresponds to at least one signal segment. The technical scheme provided by the embodiment of the invention can be used in a voice identification system.

Description

technical field [0001] The invention relates to the field of speech recognition, in particular to a method and device for extracting speech data. Background technique [0002] With the development of intelligent technology, human beings are no longer satisfied with interacting with devices through mouse, button, etc., but hope to interact with devices through voice to realize voice control of devices. Speech recognition technology, as one of the core technologies of voice interaction technology, has become increasingly mature and has been gradually applied in information processing, education and business applications, consumer electronics and other fields. [0003] Speech data extraction is an important input link of speech recognition. After the user activates the voice device, the process of extracting voice data in the prior art includes: sequentially searching for energy in the signal input by the user; and obtaining voice data from the signal input by the user accordi...
