[0004] The problem solved by the present invention is: in order to overcome the defect of low recognition rate of traditional speech emotion recognition in non-specific persons, and at the same time to solve the problem of lack of speech emotion recognition devices with good human-computer interaction functions on the market, combined with the above background and needs , the present invention provides an embedded speech emotion recognition method and device thereof. This system can recognize the speaker's emotions such as calmness, happiness, anger, fear, and calmness in a small embedded device, and according to the different emotions carried by the speaker's voice, take different action

Embodiment 1
[0036] An embedded speech emotion recognition method, comprising the following steps:
[0037] Step 1: receiving the input of the emotional speech segment to be identified;
[0038] Step 2: digitalize the emotional speech segment to be identified to provide a digital speech signal;
[0039] Step 3: Preprocessing the emotional digital voice signal X(n) to be recognized, including pre-emphasis, framing, windowing, and endpoint detection:
[0040] Step 3.1: Pre-emphasize the emotional digital voice signal X(n) to be recognized as follows:
[0041] X ( n ) ‾ = X ( n ) - αX ( n - 1 ) - - - ( 1 )
[0042] In the formula, α...

Abstract
The invention relates to an embedded type speech emotion recognition method and an embedded type speech emotion recognition device. The method comprises a feature extraction method, an emotion model training method, a Gaussian mixture model and an emotion recognition method. The method is as follows: parameters of a speech emotion recognition model can be adjusted in a self-adoption manner according to the recognition result of a speaker module, and an unspecific speaker speech emotion recognition question is transformed into a specific speaker speech emotion recognition problem. The device comprises a central processor, a power supply, a clock generator, a Nand Flash storage, a Nor Flash storage, an audio coding-decoding chip, a microphone, a loudspeaker, a keyboard, an LCD (Liquid Crystal Display) display and an USB (Universal Serial Bus) interface storage. According to the embedded type speech emotion recognition method and device, a speaker recognition model is added to the speech emotion recognition, and therefore, the problem that the speech emotion recognition is suddenly declined under an unspecific speaker condition is solved, and the identity recognition function is brought to the device.
Description
technical field [0001] The patent of the present invention relates to a speech emotion recognition technology, in particular to an embedded speech emotion recognition method and device, belonging to the field of speech emotion recognition technology. Background technique [0002] Automatic speech emotion recognition technology is a relatively marginal technology in the IT industry. Speech, as a communication medium between people, carries rich emotional information. Emotion plays an important role in human perception, decision-making and other processes, and plays an important role in human communication. With the development of science and technology, human-machine communication is becoming more and more important in people's daily life. Using voice to conduct natural and harmonious human-computer interaction has been the goal that people have been striving for for a long time. Speech emotion recognition is an important content of harmonious human-computer interaction. I...
