Abstract

An electronic device for allowing the user not to terminate audio recording while at the same time checking the content corresponding to a recorded portion in real time during the audio recording, and a method of reproducing the audio signal. An electronic device according to an embodiment disclosed in the present disclosure may include a memory configured to store an audio signal being input; a display unit configured to display at least one of an item indicating a progressive state in which the audio signal is stored therein and an STT-based text for the audio signal; a user interface unit configured to receive the selection of a predetermined portion of the item indicating the progressive state or the selection of a partial character string of the text from the user; and a controller configured to reproduce an audio signal corresponding to the selected portion or the selected character string.

Claims

1. An electronic device, comprising:

A recording function unit configured to record an external sound to store in a memory;

a touch screen configured to display a progress bar indicating a progressive state of the recording, in real time, wherein the progress bar includes a first indicator indicating a current recording time point, wherein the touch screen displays first time information indicating a current recording time along with the progress bar;

a controller configured to;

convert a voice contained in the recorded external sound into a text based on a speech-to-text (STT) conversion in real time while the recording is in progress;

control the touch screen to display the converted text while the recording is in progress;

receive a touch input for selecting a portion of the converted text while the recording is in progress;

reproduce the recorded external sound from a specific time point corresponding to the selection portion of the converted text while the recording is in progress, in response to the touch input; and

control the touch screen to display a second indicator indicating a reproduction time starting from the specific time point while the recording is in progress, in response to the touch input, wherein the second indicator is displayed together with the first indicator on the progress bar,

wherein the second indicator is moved on the progress bar in response to reproducing the recorded external sound.

2. The electronic device of claim 1, further comprising:

an interface unit configured to output the recorded external sound corresponding to the selected portion to an earphone.

3. The electronic device of claim 1, wherein the controller controls the touch screen to display second time information indicating the reproduction time point corresponding to the selected portion along with the progress bar while the recording is in progress, in response to the touch input.

4. The electronic device of claim 3, wherein second indicator and the second time information are displayed together.

5. The electronic device of claim 1, wherein the converted text is stored in the memory to associate with the recorded external sound.

6. A method of reproducing an audio signal in an electronic device, the method comprising:

recording an external sound to store in a memory;

displaying a progress bar on a touch screen indicating a progressive state of the recording, in real time, wherein the progress bar includes a first indicator indicating a current recording time point;

displaying first time information indicating a current recording time along with the progress bar;

converting a voice contained in the recorded external sound into a text based on a speech-to-text (STT) conversion, in real time, while the recording is in progress;

controlling the touch screen to display the converted text while the recording is in progress;

receive a touch input for selecting a portion of the converted text while the recording is in progress;

reproducing, the recorded external sound from a specific time point corresponding to the selected portion of the converted text while the recording is in progress, in response to the touch input; and

controlling the touch screen to display a second indicator indicating a reproduction time starting from the specific time point while the recording is in progress, in response to the touch input, wherein the second indicator is displayed together with the first indicator on the progress bar,

wherein second time information indicating the reproduction time point corresponding to the selected portion is displayed along with the progress bar while progressing the audio recording in response to the receiving the input, and

wherein the second indicator and the second time information are displayed together with the first indicator and the first time information progressing the audio recording in response to the receiving the input.

7. The method of claim 6, further comprising controlling the touch screen to display second time information indicating the reproduction time point corresponding to the selected portion along with the progress bar while the recording is in progress, in response to the touch input.

8. The method of claim 6, wherein said reproducing step comprises outputting the recorded external sound corresponding to the selected portion to an earphone.

9. The method of claim 6, wherein the second indicator and the second time information are displayed together with the first indicator and the first time information while the recording is in progress, in response to the touch input.
