Embodiment 1

[0020] refer to figure 1 , shows a flow chart of steps of a voice call method according to Embodiment 1 of the present invention.

[0021] The voice communication method of the embodiment of the present invention comprises the following steps:

[0022] Step 101: When the mobile terminal is in a call state, it is judged whether the mobile network bandwidth value is within the first preset bandwidth value range; if yes, execute step 102; if not, execute the first preset operation.

[0023] The voice call method provided by the embodiment of the present invention is suitable for processing low-pitched call voices. Even if the call sender, that is, the user, enters the call content in a low voice, the call receiver can clearly hear the call content. The call content of the sender of the call will not be disclosed.

[0024] If the mobile network broadband value is within the first preset bandwidth value range, it can be determined that the mobile network is in narrowband mode, an...

Embodiment 2

[0035] refer to figure 2 , shows a flow chart of steps of a voice call method according to Embodiment 2 of the present invention.

[0036] The voice call method in the embodiment of the present invention specifically includes the following steps:

[0037] Step 201: The mobile terminal judges whether the distance between the mobile terminal and the human ear is less than a preset distance when in a call state; if yes, execute step 202; if not, execute a second preset operation.

[0038]In the embodiment of the present invention, description will be made by taking the talking modes supported by the mobile terminal including: a hand-held talking posture, a hands-free talking mode, and a low voice talking mode as examples. Wherein, the low voice talking mode can be manually opened by the user or automatically opened by the mobile terminal. Wherein, the mobile network bandwidth value is within the first preset bandwidth value range under the hand-held talking posture, and the sa...

Embodiment 3

[0058] refer to image 3 , shows a structural block diagram of a mobile terminal according to Embodiment 3 of the present invention.

[0059] The mobile terminal in the embodiment of the present invention includes: a judging module 301, configured to judge whether the bandwidth value of the mobile network is within the first preset bandwidth value range during a call state; an adjusting module 302, configured to determine whether the bandwidth value is within the first preset bandwidth value range; Within a preset bandwidth value range, adjust the bandwidth value of the mobile network sampling signal from the first preset bandwidth value to a second preset bandwidth value to collect voice signals; wherein the first preset frequency The width value is less than the second preset bandwidth value; the speech enhancement module 303 is used to perform speech enhancement processing on the collected speech signal to obtain the processed speech signal; the resampling module 304 is use...

Abstract

The invention provides a voice call method and a mobile terminal. The method comprises the steps that whether the mobile network bandwidth value is within a first preset bandwidth value range is judged under the call state; if the bandwidth value is within the first preset bandwidth value range, the mobile network sampling signal bandwidth value is adjusted to a second preset bandwidth value from a first preset bandwidth value, and voice signals are acquired, wherein the first preset bandwidth value is less than the second preset bandwidth value; voice enhancement processing is performed on the acquired voice signals so as to obtain the processed voice signals; and the processed voice signals are resampled according to the first preset bandwidth value and transmitted to opposite end equipment through the mobile network. With application of the voice call scheme, the call receiver is ensured to clearly hear the content of the call even the caller, i.e. the user, makes the call in a low voice so that the high-quality low voice call service can be provided for the user.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a voice communication method and a mobile terminal. Background technique [0002] With the rapid development of the mobile Internet and the dependence of fashionable young people on mobile terminals, mobile terminals are becoming more and more popular. Calls are the basic function of mobile devices, and consumers have higher and higher requirements for call quality. At present, the mobile terminal can only provide two communication modes of handle communication and hands-free communication. Specifically, when the mobile terminal is close to the human ear, the handheld communication mode can be used for communication, and when the mobile terminal is far away from the caller, the hands-free communication can be used. mode to make a call. [0003] When the current call sender uses a mobile terminal, he pays more and more attention to personal information security and ...
