Abstract

A method of writing a specific time point through a familiar pattern input that can be instantaneously applied to a portion desired to be memorize or highlighted by the user during audio recording. An electronic device according to an embodiment disclosed in the present disclosure may include a storage unit configured to store audio data and the recording information of the audio data; a controller configured to convert an input audio signal into audio data to store the audio data; a display unit configured to display one or more texts based on the execution of a speech-to-text (STT) for the input audio signal; and an input unit configured to receive a specific pattern input or a selection input for part of the texts from the user while receiving the audio signal.

Claims

1. An electronic device, comprising:

a display unit;

a microphone configured to receive an audio signal;

a storage unit configured to store audio data corresponding to the audio signal;

a controller configured to;

convert an input audio signal into audio data to store the audio data;

receive, via an input unit, at least one specific pattern while receiving the audio signal through the microphone;

store recording information comprising one or more time points at which the at least one specific pattern is input and the audio data to the storage unit;

reproduce the audio data stored in the storage unit in response to a request for executing an audio data reproduction function,

wherein an audio data reproduction screen comprising a progress bar indicating a reproduction state of the audio data is displayed while the audio data is reproduced, and

wherein an indicator indicating a current reproduction time point and one or more indicators indicating the one or more time points at which the at least one specific pattern is received is displayed on the progress bar;

receive an input for selecting an indicator among the one or more indicators displayed on the progress bar; and

control the audio data to reproduce from a time point corresponding to the selected indicator.

2. The electronic device of claim 1, wherein the controller acquires the one or more time points at which the specific pattern is received from the recording information of the audio data when there is an access request to the audio data.

3. The electronic device of claim 1, wherein the audio data and the recording information of the audio data constitute a file.

4. The electronic device of claim 1, wherein the audio data and the recording information of the audio data constitute a separate file.

5. The electronic device of claim 1, wherein the at least one specific pattern input is a touch input to a specific region or a selection input to a specific key button.

6. The electronic device of claim 1, wherein the at least one specific pattern input comprises any one of a change of tactile feeling at a specific region, a change of acceleration of the electronic device, and a change of angular speed of the electronic device.

7. The electronic device of claim 1, wherein the at least one specific pattern input is a specific voice command.

8. The electronic device of claim 1, wherein the at least one specific pattern input is a voice with an intensity or volume above a threshold value.

9. A method of controlling the operation of an electronic device, the method comprising:

converting an input audio signal received through a microphone into audio data to store the audio data;

receiving, via an input unit, at least one specific pattern while receiving the audio signal through the microphone;

storing recording information comprising one or more time points at which the at least one specific pattern is input and the audio data to a storage unit;

reproducing the audio data stored in the storage unit in response to a request for executing an audio data reproduction function,

wherein an audio data reproduction screen comprising a progress bar indicating a reproduction state of the audio data is displayed while the audio data is reproduced, and

wherein an indicator indicating a current reproduction time point and one or more indicators indicating the one or more time points at which the at least one specific pattern is received is displayed on the progress bar;

receiving an input for selecting an indicator among the one or more indicators displayed on the progress bar; and

controlling the audio data to reproduce from a time point corresponding to the selected indicator.

10. The method of claim 9, further comprising:

acquiring the one or more time points at which the at least one specific pattern is received from the recording information of the audio data when there is an access request to the audio data.

11. The method of claim 9, wherein the audio data and the recording information of the audio data constitute a file.

12. The method of claim 9, wherein the audio data and the recording information of the audio data constitute a separate file.

13. The method of claim 9, wherein the at least one specific pattern input is a touch input to a specific region or a selection input to a specific key button.

14. The method of claim 9, wherein the at least one specific pattern input comprises any one of a change of tactile feeling at a specific region, a change of acceleration of the electronic device, and a change of angular speed of the electronic device.

15. The method of claim 9, wherein the at least one specific pattern input is a specific voice command.

16. The method of claim 9, wherein the at least one specific pattern input is a voice an intensity or volume above a threshold value.
