[0041] see figure 1 , which is a block diagram of a mobile terminal according to the first embodiment of the present invention.

[0042] A mobile terminal, which includes: a receiving module 11 , a conversion module 12 , an identification module 13 , a modeling module 14 , and a processing module 15 . Among them, the receiving module 11, the conversion module 12, the identification module 13, the modeling module 14, and the processing module 15 are electrically connected sequentially. Of course, the connection relationship of the aforementioned modules is not limited to this, for example, for some purposes, more intelligent Or conveniently, the processing module 15 is electrically connected to the receiving module 11 , the converting module 12 , the identifying module 13 , and the modeling module 14 respectively.

[0043] The receiving module 11 is used for receiving voice signals. For example, the voice signal is a narrowband (4KHZ) voice signal.

Abstract

The invention discloses a mobile terminal. The mobile terminal comprises a receiving module, a conversion module, a recognition module, a modeling module and a processing module. The receiving module is used for receiving voice signals. The conversion module is used for converting the received voice signals from a time domain into a frequency domain to acquire the converted voice signals; the recognition module is used for measuring frequency response of the converted voice signals to recognize voice characteristic frequency of a voice signal initiator; the modeling module is used for building a voice production model corresponding to the voice characteristic frequency of the voice signal initiator; the processing module is used for compensating for missing components at a low-frequency part of the voice signals according to the voice production model and enhancing the strength of the voice characteristic frequency. Harmonic components of the voice characteristic frequency are added to a high-frequency part of the voice signals. The invention further discloses a voice signal processing method of the mobile terminal. By the adoption of the mobile terminal and the voice signal processing method, the processed voice signals sound more full or clearer, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a mobile terminal and a voice signal processing method thereof. Background technique [0002] When a mobile terminal such as a mobile phone is making a call, the sound is not full due to channel noise interference in narrowband transmission. Or, due to other reasons, the voice of the mobile phone is not clear, which affects the user experience. Contents of the invention [0003] In view of this, the technical problem to be solved by the present invention is to provide a mobile terminal and a voice signal processing method thereof, so that the processed voice signal sounds fuller or clearer and enhances user experience. [0004] The technical solution adopted by the present invention to solve the problems of the technologies described above is as follows: [0005] A mobile terminal, comprising: [0006] A receiving module, configured to receive voice signals; ...
