Embodiment 1

As shown in FIG. 1, the call voice recording method for a mobile terminal provided by this embodiment includes the following steps:

Step S100: After the call starts, detecting the external noise information and the call voice information of the other party; Step S101: comparing the external noise information with the volume information respectively included in the call voice information of the other party;

Step S102, when the external noise volume is higher than the voice volume of the other party call, go to step S103, otherwise, go to step S100;

Step S103: Convert the voice message of the other party into matching text information, and display the information through the information display module of the mobile terminal.

The detected external noise information and the other party's call voice information respectively include frequency information (hertz) and volume information (decibel). In this embodiment, before determining whether to convert the other party's call voice information into text information, Only the external noise information and the volume information of the other party's voice information are compared. This is because when the user uses the mobile terminal to make a call in a noisy environment, the most important factor affecting the information acquisition is the external noise. The volume is higher than the voice volume of the other party's call, so that the user misses the call content of the other party. In this embodiment, when it is determined that the volume of the external noise is higher than the volume of the voice of the other party, the voice information of the other party is converted into the matched text information, and displayed by the information display module of the mobile terminal, so that the user will miss the voice. The content of the other party's call is displayed in text form on the information display module of the user's mobile terminal (for example, the capacitive touch screen of the smart phone).

Wherein, converting the voice information of the other party's call into the matched text information is through the following technology The solution realizes: firstly acquiring a voice signal in the voice message of the other party's call; then matching the voice signal with the corresponding text in the text library, and acquiring a text string matching the whole voice signal; The text strings are sequentially combined in the chronological order of the voice information into text information that can be displayed on the mobile terminal.

In a preferred embodiment of the present embodiment, in the step S100, when the related text information is also acquired, the mobile terminal stores the converted text information, so that the user can refer to the call after the call is completed.

Setting, the first volume threshold may be customized according to the characteristics of the user, and the setting purpose is that when the external noise affects the user to answer the call, the volume of the external noise collected by the mobile terminal in real time is higher than the setting. When the first volume threshold is used, the voice message of the other party is converted into the matched text information, and is displayed by the information display module of the mobile terminal. In a preferred embodiment of the embodiment, in step S203, the acquired text information is also stored. Generally, the volume of the external noise collected by the mobile terminal exceeds the first volume threshold set by the user for a short time, so that the voice-to-word processing process adopted by the mobile terminal is correspondingly shortened, which makes the obtained text relatively relatively simple. Less, making the user's later understanding relatively difficult, so in this embodiment, once the external noise volume is higher than the first volume threshold, the other party's call voice information is converted into the matched text information for a period of time. The size of the time can be pre-defined by the user.

For the same reason, the method for converting the voice information of the other party into the matched text information is referred to the first embodiment.
