Embodiment Construction

[0118] An embodiment of the present invention will be further described below in conjunction with the accompanying drawings.

[0119]In the embodiment of the present invention, the model system is mainly divided into two modules: a speech modeling module and a speech dynamic real-time processing module, wherein the speech modeling module realizes speaker speech modeling, and the speech dynamic real-time processing module realizes mixed human Direction localization and separation of sound, hybrid speech recognition and extraction (that is, extraction and amplification of the target sound and shielding of other sounds).

[0120] A kind of intelligent voice processing method, the method flowchart is as follows figure 1 shown, including the following steps:

[0121] Step 1. Collect sample speech segments to build a sample speech library, perform feature extraction on sample speech, obtain feature parameters, and train feature parameters; the specific process is as follows:

Abstract

The invention relates to a smart voice processing method and belongs to the technical field of information processing. The smart voice processing method is characterized by achieving smart identification of identities of multiple talkers in the multi-person voice environment and separating mixed voices by building a talker voice model base so as to obtain independent voice of each talker, amplifying voices of the talkers to be heard according to user demands and eliminating voices of talkers not required by the users. Different from the traditional hearing aid, the smart voice processing method can be used for automatically providing needed voices for the users according to user demands, reduces interference of non-target voices except for noise, and has individuation, interaction and intelligentization.

Description

technical field [0001] The invention belongs to the technical field of information processing, and in particular relates to an intelligent voice processing method. Background technique [0002] According to the latest assessment data released by the World Health Organization (WHO) in 2013, there are currently 360 million people in the world with hearing impairments of varying degrees, accounting for 5% of the total global population. The use of hearing aid products can effectively compensate for the hearing loss of hearing-impaired patients and improve their quality of life and work. However, the current research on hearing aid system technology still focuses on noise suppression and source sound amplitude amplification, and rarely involves sound feature-based modeling and multi-sound source automatic separation technology. When the actual application scenario is very complex, for example: at a party, multiple speakers speak at the same time, even accompanied by background ...
