Abstract

A method for processing signals, a terminal device, and a non-transitory computer-readable storage medium are provided. The method includes the following. A sound signal of external environment is recorded via a microphone of a headphone when the headphone is in a playing state. Feature audio in the sound signal is identified and reminding information corresponding to the feature audio is acquired. Inquire of a user whether recorded sound signal is critical according to the reminding information in response to the headphone being paused. An input operation of the user is detected and the sound signal is processed according to the input operation of the user.

First claim

What is claimed is:

1. A method for processing signals, comprising:
recording, via a microphone of a headphone, a sound signal of external environment when the headphone is in a playing state;
identifying feature audio in the sound signal and acquiring reminding information corresponding to the feature audio;
inquiring of a user whether recorded sound signal is critical according to the reminding information, in response to the headphone being paused; and
detecting an input operation of the user and processing the sound signal according to the input operation of the user.

2. The method of claim 1 , wherein the microphone comprises a first microphone and a second microphone, and the recording, via a microphone of a headphone, a sound signal of external environment when the headphone is in a playing state comprises one of the following:
recording, via the first microphone of the headphone, the sound signal of external environment when playing music through the headphone; and
recording, via the second microphone of the headphone, the sound signal of external environment when the user talking through the headphone.

3. The method of claim 2 , wherein the recording, via a microphone of a headphone, a sound signal of external environment when the headphone is in a playing state comprises:
acquiring the sound signal of the external environment recorded via the first microphone of the headphone within a preset time period when playing music through the headphone, the preset time period being determined according to a time period in which the music is played; and
generating and storing an audio file corresponding to the sound signal recorded.

4. The method of claim 1 , further comprising the following prior to the identifying feature audio in the sound signal:
detecting whether the sound signal contains a valid sound signal; and
conducting a smooth-filter process on the sound signal when the sound signal contains the valid sound signal.

5. The method of claim 1 , wherein the identifying feature audio in the sound signal and acquiring reminding information corresponding to the feature audio comprises:
determining whether the sound signal contains the feature audio according to a preset sound model; and
determining the reminding information corresponding to the feature audio according to a correspondence between feature audio and reminding information, based on a determination that the sound signal contains the feature audio.

6. The method of claim 5 , wherein the determining whether the sound signal contains the feature audio according to a preset sound model comprises at least one of:
extracting noise information in the sound signal and determining whether the noise information matches a preset noise model;
extracting voiceprint information in the sound signal and determining whether the voiceprint information matches a sample voiceprint information; and
extracting sensitive information in the sound signal and determining whether the sensitive information matches a preset keyword.

7. The method of claim 1 , wherein the inquiring of a user whether recorded sound signal is critical according to the reminding information, in response to the headphone being paused comprises one of:
inquiring of the user whether the recorded sound signal is critical according to the reminding information in response to music switching being detected, in a process of playing music through the headphone; or
inquiring of the user whether the recorded sound signal is critical according to the reminding information in response to a music pause instruction being received, in the process of playing music through the headphone.

8. The method of claim 1 , wherein the detecting an input operation of the user and processing the sound signal according to the input operation comprises:
receiving the input operation of the user on the headphone and determining whether to play the sound signal according to the input operation; and
playing the sound signal based on a determination that the sound signal is to be played; or
deleting a stored audio file corresponding to the sound signal based on a determination that the sound signal is not to be played.

9. The method of claim 8 , wherein the playing the sound signal comprises:
acquiring, via the headphone, at least one of geographic location information and time information of the sound signal; and
generating a target audio file according to the sound signal and the at least one of geographic location information and time information of the sound signal, and playing the target audio file.

10. A terminal device, comprising:
at least one processor; and
a computer readable storage, coupled to the at least one processor and storing at least one computer executable instruction thereon which, when executed by the at least one processor, cause the at least one processor to carry out actions, comprising;
recording a sound signal of external environment when a headphone is in a playing state;
identifying feature audio in the sound signal and acquiring reminding information corresponding to the feature audio;
inquiring of a user whether recorded sound signal is critical according to the reminding information, in response to the headphone being paused; and
detecting an input operation of the user and processing the sound signal according to the input operation of the user.

11. The terminal device of claim 10 , wherein the at least one processor carrying out the action of recording the sound signal of external environment when the headphone is in the playing state is caused to carry out actions, comprising:
acquiring the sound signal of the external environment within a preset time period when playing music through the headphone, the preset time period being determined according to a time period in which the music is played; and
generating and storing an audio file corresponding to the sound signal recorded.

12. The terminal device of claim 10 , wherein the at least one processor is further caused to carry out actions, comprising:
detecting whether the sound signal contains a valid sound signal; and
conducting a smooth-filter process on the sound signal when the sound signal contains the valid sound signal.

13. The terminal device of claim 10 , wherein the at least one processor carrying out the action of identifying the feature audio in the sound signal and acquiring the reminding information corresponding to the feature audio is caused to carry out actions, comprising:
determining whether the sound signal contains the feature audio according to a preset sound model; and
determining the reminding information corresponding to the feature audio according to a correspondence between feature audio and reminding information, based on a determination that the sound signal contains the feature audio.

14. The terminal device of claim 13 , wherein the at least one processor carrying out the action of determining whether the sound signal contains the feature audio according to the preset sound model is caused to carry out actions, comprising at least one of:
extracting noise information in the sound signal and determining whether the noise information matches a preset noise model;
extracting voiceprint information in the sound signal and determining whether the voiceprint information matches a sample voiceprint information; and
extracting sensitive information in the sound signal, determining whether the sensitive information matches a preset keyword.

15. The terminal device of claim 10 , wherein the at least one processor carrying out the action of inquiring of the user whether re
