Problems solved by technology

In the prior art, it is necessary to use more data to estimate a feature vector with better performance. When there is little data, the estimated feature vector cannot bring about a significant improvement in speech recognition performance.
However, for some speech recognition application scenarios, the user often only gives a very short speech (for example, the user only gives a short sentence of "find nearby hotels"), which puts forward higher requirements for speech recognition adaptation

Embodiment Construction

[0024] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe operations as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

[0025] The computer equipment includes user equipment and network equipment. Wherein, the user equipment includes, but is not limited to, computers, smart phones, PDAs, etc.; Or a cloud composed of network servers, among them, cloud computing is a kind of distributed computing, a super virtual computer composed of a group of loosely coupled computer sets. Whe...

Abstract

The present invention provides a speech recognition method and device, wherein the method includes: performing clustering processing on training data feature vectors to obtain clustering training data feature vectors; using the clustering training data feature vectors to perform Interpolation calculation: input the feature vector of the data to be recognized after the interpolation calculation into the speech recognition model for adaptive adjustment of the speech recognition model. The invention can improve the accuracy and processing efficiency of speech recognition self-adaptation.

Description

technical field [0001] The invention relates to the technical field of voice recognition, in particular to a voice recognition method and device. Background technique [0002] Speech recognition technology, also known as Automatic Speech Recognition (ASR), aims to convert the lexical content of human speech into computer-readable input, such as keystrokes, binary codes, or character sequences. Speech recognition is an interdisciplinary subject, and the fields involved include: signal processing, pattern recognition, probability theory and information theory, vocal mechanism and auditory mechanism, artificial intelligence, etc. In recent years, speech recognition technology has made remarkable progress and has begun to move from the laboratory to the market. Speech recognition technology has entered or is about to enter various fields such as industry, home appliances, communications, automotive electronics, medical care, home services, and consumer electronics. [0003] Sp...
