Embodiment 1

[0044] This embodiment provides a speech language recognition method based on confidence, such as figure 1 shown, including steps:

[0045] S11: extracting a voice segment from each voice segment as a preset voice segment, comparing it with a preset language database, and obtaining language information matching the preset voice segment;

[0046] S12: According to the language information, obtain the language confidence and confidence average of each speech segment, and judge whether the confidence average is greater than a preset reliability threshold, and if so, use the current language as the default language of the voice information;

[0047] S13: If not, filter the speech segments according to the preset filtering conditions until the average confidence value of the language is greater than the preset threshold, and obtain the filtered speech segments, and go to step S11.

[0048] In this embodiment, before step S11, it also includes:

[0049] Step S101: receiving input ...

Embodiment 2

[0076] This embodiment provides a speech language recognition system based on confidence, such as figure 2 shown, including:

[0077] Language matching module 22: for extracting a voice segment from each voice segment as a preset voice segment, comparing it with the preset language database, and obtaining language information matching the preset voice segment.

[0078] Language identification module 23: used to obtain the language confidence and confidence mean value of each speech segment according to the language information, and judge whether the confidence mean value is greater than a preset reliability threshold, and if so, use the current language as the voice message default language,

[0079] Screening module 24: for if not, then by preset screening conditions, screen each speech segment until the language confidence mean value is greater than the preset threshold, and obtain the screened speech segment, turn to to the language matching module.

[0080] In this emb...

Abstract

The invention provides a voice language recognition method and system based on the confidence degree, aiming to solve the problem that in the existing voice recognition, the language recognition efficiency is low. The method comprises the following steps: S1, extracting a voice segment from each voice segment as a preset voice segment, comparing with a preset language database, acquiring the language information matched with the preset voice segment; S2, acquiring the language confidence degree and the confidence degree average value of each voice segment according to the language information,judging whether the confidence degree mean value is larger than a preset credibility threshold value or not, if yes, the current language is used as the default language of the voice information; S3,if not, screening all the voice segments through a preset screening condition, until the mean value of the language confidence degree is larger than the preset threshold value, and acquiring the voice fragment obtained by the screening, and turning to the step S1. By adopting the voice language recognition method and device, the voice recognition efficiency is improved, and meanwhile, the recognition accuracy of the multi-language voice information is further improved.

Description

technical field [0001] The invention relates to the field of speech recognition, in particular to a speech language recognition method and system based on confidence. Background technique [0002] Speech recognition technology, also known as automatic speech recognition, aims to convert the lexical content in human speech into computer-readable input, such as keystrokes, binary codes or character sequences. In the past two decades, speech recognition technology has made significant progress Progress has begun to move from the laboratory to the market. Speech recognition technology will enter various fields such as industry, home appliances, communications, automotive electronics, medical care, home services, and consumer electronics. [0003] In the prior art, language recognition needs to be performed before speech recognition. In the prior art, after the client divides the speech signal input by the user into several speech fragments, the speech fragments are sequentially ...
