Abstract
The invention discloses a receiver unit having the voice recognition function. The receiver unit comprises a voice input module, an audio frequency processing module, a voice recognition module and a storage module. The voice input module is used for receiving voices in the surrounding environment. The storage module is used for storing predetermined effective voice patterns. The voice recognition module is used for recognizing the types of a received voice based on predetermined effective voice patterns. If the received voice is recognized by the voice recognition module as the effective voice, the voice is not filtered. If the received voice is recognized by the voice recognition module as the noise, the voice is filtered out. The receiver unit has the voice recognition function and received voices are subjected to the basic filtering treatment. Meanwhile, the speed range, the vocabulary accumulative total and the like for effective voices are preset. In this way, the influence caused by the frequency sweeping approach can be avoided. For example, the conditions that effective voices are filtered out, the filtering effect is unsatisfactory and the like, are avoided. The voice receiving quality is improved.
Description
Technical field
The present invention relates to voice processing technology field, be specifically related to a kind of receiver unit with speech identifying function.
Background technology
Environment it is typically due to noisy, it is impossible to catch the sound of phone when people receive calls out of doors, and universal along with mobile phone, important way as interpersonal communication, much important thing is all passed on by mobile phone, therefore possesses the receiver unit of noise filter function, by extensive concern.
The application for a patent for invention of application number 201320611465.1, disclose a kind of receiver with filtering noise function, including receiver's housing (1), and the tone-entering hole (2) on receiver's housing (1) two ends and go out acoustic aperture (3) respectively, noise filter (4) and speaker (5) it is provided with in described receiver's housing (1), described noise filter (4) is placed in the positive lower end of tone-entering hole (2), it is serially connected in internal sound signal processing apparatus loop, described speaker (5) is in the positive lower end going out acoustic aperture (3), it is serially connected in out in signal processor loop.
This novel advantage is to be provided with noise filter in receiver, it is possible to decrease the interference of ambient noise, it addition, be additionally provided with speaker in receiver, is prevented effectively from that the other side's sound is too small and the problem that affects exchange, it is ensured that the normal communication of both sides' phone.
But, noise filter is the equal of a wave filter, by artificially arranging a noise threshold, the sound frequency of reception and this noise threshold is compared, lower than sound frequency be filtered.And somebody itself speaks, the frequency of sound is just relatively low, it is easy to is near this noise threshold, and is filtered, then even if useful voice reception people still cannot hear.If what this noise threshold arranged is too low, the effect of filtering noise can not had again.
