Abstract

The invention provides a voice information identification method and system. The identification method comprises the steps of extracting sample voice feature parameters from sample voice data corresponding to personalized information, using the sample voice feature parameters to train a Gaussian mixed model to obtain a personalized model, extracting to-be-identified voice feature parameters from to-be-identified voice data, matching the to-be-identified voice feature parameters with the personalized model, and determining the personalized information on the basis of the to-be-identified voice feature parameters and the personalized model. The voice information identification method and system can identify the personalized information such as gender and age of a talker from the to-be-identified voice data, and the identified personalized information leaves larger operable space for the subsequent operations such as voice assistant and voice dialogue; in addition, the voice information identification method and system can also identify text information, the personalized information identification and the text information identification share one set of voice feature parameters, and the personalized information identification is smaller than the text information identification in computing amount, so the effect on the identification speed of the text information is smaller.

Description

technical field [0001] The invention relates to the technical field of information recognition, in particular to a voice information recognition method and system. Background technique [0002] With the development of electronic technology, electronic equipment has been upgraded to have more and more functions. Among them, the voice control function has attracted much attention, and various voice assistant applications have emerged. Voice assistant applications enable users to use electronic equipment Read text messages, introduce restaurants, ask about the weather, and more. [0003] The key to realizing voice assistant applications is the voice recognition system. The voice recognition process of the voice recognition system is the process of converting the user's voice information into text information. However, the inventor found in the process of realizing the invention that: the speech recognition system in the prior art can only complete simple conversion from speech...
