The invention discloses a digital hearing aid-oriented scene matching method. The method comprises the steps of obtaining a sound signal, and obtaining a signal sample according to the sound signal; performing the first feature extraction on the signal sample to realize the initial scene matching; and based on an initial matching result, carrying out the second feature extraction on the signal sample to realize the final scene matching. According to the method provided by the invention, through the twice feature extraction and classification of two different classifiers, the classification precision can be effectively improved, the calculation speed is high, the requirement of real-time processing can be met, and the method and the device are very suitable for the application market of hearing aids and have very high practical value.
Description
technical field [0001] The invention relates to the technical field of speech signal processing, in particular to a scene matching method, device and computer equipment for digital hearing aids. Background technique [0002] Hearing is one of the important senses of human beings, and it is an important part of communication and communication with the surroundings. Its importance is no less than that of vision. In recent years, due to global noise pollution and the aging of the world's population structure, the global population of hearing loss is increasing day by day. For centuries, scientists have been using various means to help hearing-impaired patients improve their hearing. Before there was a major medical breakthrough, wearing hearing aids was one of the most common ways to compensate for hearing loss. [0003] With the development of digital hearing aid technology, auditory scene classification has become one of the core functions of intelligent digital hearing aids...
