Problems solved by technology

[0004] The disadvantage of this is that when the pronunciation is inaccurate, or the user has various accents, or is used in an environment with strong external interference, the speech recognition engine will often give wrong recognition, which greatly reduces the user experience and gives User confusion and inconvenience

Embodiment Construction

[0029] The following non-limiting examples serve to illustrate the invention.

[0030] A method for specific person speech recognition in the present invention, the following describes each step of the method one by one.

[0031] Step 1. First define a voice data buffer and a reference voice database in advance. Among them, the voice data cache is used to retain the original voice data to facilitate subsequent operations; the reference voice database is used as the criterion for re-recognition, and one reference voice data corresponds to a recognized word, and contains the original voice data, acoustic features and recognition factors.

[0032] Step 2. The specific person reads the recognition words in the recognition library and sends out a voice signal, and then the voice signal collection module collects voice data. The voice signal acquisition module is used to collect voice signals and preprocess the collected voice signals. First, the voice signal is amplified through an ampli...

Abstract

The invention discloses a speaker-dependent voice recognizing method. The speaker-dependent voice recognizing method is characterized in that a voice data cache and a benchmark voice database are defined preliminarily, and original voice signals are stored in the voice data cache and sent to a voice signal recognition engine to be processed and recognized to acquire recognition results with acoustic features and recognition factors; the benchmark voice database is judged whether to have benchmark voice data or not; if the benchmark voice database has no benchmark voice data, the benchmark voice data are initialized according to voice signal recognition engine results; if the benchmark voice database has the benchmark voice data, corresponding processing methods are selected to process according to different voice signal recognition engine results, so that the benchmark voice data are updated or recognition results of the voice signal recognition engine are corrected; and finally a speaker dependent pronounces the same recognition word repeatedly, and the previous steps are performed repeatedly to update the benchmark voice data continuously to make the benchmark voice data to be optimal. The speaker-dependent voice recognizing method has the advantages that speaker-dependent voice recognition efficiency is improved, and voice false recognition and recognition rejection are reduced; and with the increase of the number of use of users, the benchmark voice data in the benchmark voice database are reliable, recognition accuracy and efficiency are increased, and user experience effects are improved well.

Description

Technical field [0001] The invention belongs to the field of computer software technology, and particularly relates to a specific person speech recognition software application technology in an embedded environment. Background technique [0002] Nowadays, with the rapid development of information technology, more and more intelligent technologies are widely used in household appliances and other equipment. Intelligence can be said to be the development trend of home appliances in the future. In recent years, smart home appliances can be seen everywhere around us, such as Internet-enabled TVs, etc., intelligent temperature control, automatic speed adjustment air conditioners, etc., are no longer in the market. Rare. Voice recognition is also an important intelligent technology, which is increasingly applied to various devices. [0003] Speech recognition is an interdisciplinary subject. In the past two decades, speech recognition technology has made significant progress and has be...
