Embodiment 1

[0027] refer to figure 1 , which shows a flow chart of the speech signal restoration method in Embodiment 1 of the present invention, which may specifically include the following steps:

[0028] Step 110, when it is detected that there is discontinuity in the received original speech signal, convert the continuous part of the original speech signal into reference text.

[0029] In the embodiment of the present invention, when the mobile terminal detects that there is discontinuity in the received original voice signal, it can first extract the voiceprint features of the continuous part of the original voice signal, and then calculate the extracted voiceprint features according to each preset voiceprint The probability of the model, and the preset voiceprint model with the highest probability of conformity is determined as the preset voiceprint model corresponding to the extracted voiceprint features, and then determined from the corresponding relationship between the stored pr...

Embodiment 2

[0039] refer to figure 2 , which shows a flow chart of the speech signal restoration method in Embodiment 2 of the present invention, which may specifically include the following steps:

[0040] Step 210, enabling the voice signal repair function of the mobile terminal.

[0041]In the embodiment of the present invention, the voice repair option can be provided in the system setting menu of the mobile terminal. When the user uses the mobile terminal for the first time or makes a call for the first time, the voice repair option can be triggered by operations such as sliding or clicking, thereby enabling the voice of the mobile terminal. Signal repair function, after which the mobile terminal can repair the voice signal during the call. However, when the voice repair option is not triggered by the user, the mobile terminal will not repair the voice signal during the call, thereby improving the user's choice of autonomy and improving user experience.

[0042] Step 220, when it ...

Embodiment 3

[0072] refer to image 3 , which shows a structural block diagram of a mobile terminal 300 according to Embodiment 3 of the present invention, which may specifically include:

[0073] The first converting module 301 is configured to convert the continuous part of the original speech signal into a reference text when it is detected that the received original speech signal is discontinuous;

[0074] A determination module 302, configured to determine the missing text corresponding to the missing part of the original speech signal from the stored vocabulary database according to the reference text;

[0075] The second conversion module 303 is used to convert the missing text into a compensated speech signal;

[0076] The restoration module 304 is configured to insert the compensated speech signal into the position of the missing portion of the original speech signal, and play the original speech signal inserted into the compensated speech signal.

[0077] In the embodiment of t...

Abstract

The invention provides a voice signal repairing method and a mobile terminal, relating to the technical field of mobile terminals. The method comprises the following steps: when detecting that a received original voice signal has interruption, converting a continuous part of the original voice signal into reference characters; according to the reference characters, determining missing characters corresponding to a missing part of the original voice signal from a stored vocabulary database; converting the missing characters into a compensation voice signal; and inserting the compensation voice signal into the position of the missing part of the original voice signal, and playing the original voice signal inserted into the compensation voice signal. Therefore, the problem that after a voice signal is repaired through an existing method, the semantics expressed by the voice signal is still incomplete is solved, and thus the conversation quality is improved.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a voice signal restoration method and a mobile terminal. Background technique [0002] With the rapid development of terminal technology, people have higher and higher requirements for the experience effect of the terminal. Among them, the call function is a basic function of terminals such as mobile phones, and its stability is also increasingly valued by people. Whether it is a traditional call or a wireless network-based VoIP (Voice over Internet Protocol, network call), the quality of the terminal call will directly affect the user experience. However, during the call through the terminal, due to network instability or base station transmission During the process of shielding and other reasons, the call will appear intermittent. [0003] At present, the implementation process of repairing intermittent voice signals is as follows: when the terminal detects that the r...
