Problems solved by technology
This method requires enough semantic analysis templates, but in fact, the number of semantic analysis templates is limited, and the voice signal is expressed in a variety of ways, so there are often some situations that cannot be accurately matched, resulting in the inability to accurately analyze the voice signal Semantics

Embodiment Construction
[0031] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of the embodiments of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0032] In the prior art, a method of matching a preset semantic analysis template with a speech recognized character string is mainly used to perform semantic analysis on the speech signal. This method requires enough semantic parsing templates, but in fact the number of semantic parsing templates is limited, and the voice signal expr...

The embodiment of the invention provides a voice signal processing method and device. The method comprises steps of: receiving a voice signal transmitted from a client; performing voice recognition on the voice signal to obtain text data; performing fixed sentence pattern semantic parsing on the text data to obtain an initial parsing result including a fixed sentence pattern and entity words; converting the entity words in the initial parsing result into a pinyin flow to obtain an intermediate parsing result; sending the intermediate parsing result to the client in order that the client corrects the pinyin flow in the intermediate parsing result by using a local information database to obtain a final parsing result. The voice signal processing method and device may increase semantic parsing accuracy.
Description
Technical field [0001] The embodiments of the present invention relate to the technical field of speech recognition, and in particular to a method and device for processing speech signals. Background technique [0002] With the development of voice recognition technology, there are more and more applications based on voice recognition, such as voice dialing, voice navigation, voice playback control, voice information retrieval, etc. In applications based on speech recognition, it is necessary to perform semantic analysis on the speech signal, extract the user's intention expressed by the speech signal, and convert it into a structured data format that the machine can understand. [0003] The prior art mainly uses a method of matching a preset semantic analysis template with a speech-recognized character string to perform semantic analysis on a speech signal. This method requires enough semantic parsing templates, but in fact the number of semantic parsing templates is limited, and...
