Example Embodiment

[0021] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples cited are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0022] Such as figure 1 As shown, a local accent speech recognition system based on an embedded mobile device includes a model training module, a feature extraction module, and a pattern matching module integrated on the embedded mobile device. The model training module is used to perform local accent speech recognition. Collect and train to obtain the term model of the local accent; the feature extraction module is used to extract the voice features of the input local accent; the pattern matching module is used to compare the voice features according to the term model Perform voice matching calculations to obtain voice recognition results.

[0023] Specifically: the term model includes an acoustic model and a linguistic model...

Abstract

The invention relates to a local accent speech recognition system based on an embedded mobile device. The system comprises a model training module, a feature extraction module and a pattern matching module which are integrated on an embedded mobile device. The model training module is used for collecting and training local accent speech to get an entry model of local accent. The feature extraction module is used for extracting the speech features of an input local accent. The pattern matching module is used for carrying out speech matching calculation on the speech features according to the entry model to get a speech recognition result. The local accent speech recognition system based on an embedded mobile device of the invention can improve the recognition rate of dialectal speech, reduce the difficulty of learning and training during speech recognition used by dialect speakers, and reduce the workload of learning and training. Meanwhile, the system introduces the speech recognition technology to a variety of embedded mobile devices, and can realize intelligent interaction.

Description

technical field [0001] The invention relates to the field of speech recognition, in particular to a local accent speech recognition system based on an embedded mobile device. Background technique [0002] Speech recognition research in China started in 1958, when the Institute of Acoustics of the Chinese Academy of Sciences used a tube circuit to recognize 10 vowels. It was not until 1973 that the Institute of Acoustics of the Chinese Academy of Sciences started computer speech recognition. Due to the constraints of the conditions at that time, China's speech recognition research has been in a stage of slow development. The language model currently used in China is only a probabilistic model. In order for a computer to truly understand human language and express it visually, it must make progress in recognition, which is quite a difficult job. In addition, with the continuous development of hardware resources, some core algorithms such as feature extraction, search algorit...
