## Abstract

A mobile terminal including a voice receiving unit configured to receive input voice, a controller configured to convert the received input voice to text, a display configured to display the converted text, and an input unit configured to select a word included in the displayed converted text. Further, the controller is further configured to control the display to display a plurality of possible candidate words corresponding to the selected word in an arrangement in which a corresponding displayed candidate word is displayed with a proximity from the selected word that is based on how similar the corresponding candidate word is to the selected word.

## Claims

### Claim 1

A mobile terminal, comprising:
a voice receiving unit;
a display unit;
an input unit; and
a controller configured to:
convert the voice input received via the voice receiving unit into text;
control the display unit to display the text in which a word of the text is emphatically displayed if a voice recognition rate of the word is less than a preset reference value;
receive a first touch selection signal indicating an emphasized word is touch selected for correction;
control the display unit to display a plurality of candidate words to replace the selected word;
receive a second touch signal indicating a candidate word is selected from the plurality of candidate words; and
replace the selected word with the candidate word and stop displaying the plurality of candidate words when the second touch signal is received,
wherein the controller is further configured to:
simultaneously display the converted text in a first direction and display the plurality of candidate words in a list in a second direction perpendicular to the first direction;
display a slide bar with the selected word being positioned with respect to a first position on the slide bar;
receive a touch and slide action on the slide bar; and
display candidate words at different positions on the slide bar based on the touch and slide action, and
wherein as the touch and slide action slides away from the position of the selected word, candidate words having a lower similarity to the selected word are displayed, and as the touch and slide action slides toward the position of the selected word, candidate words having a higher similarity to the selected words are displayed.

### Claim 2 (depends on 1)

The mobile terminal of claim 1, wherein the display unit is further configured to display a corresponding candidate word that has a highest similarity to the selected word closest to the selected word, and to display a corresponding candidate word that has a lowest similarity to the selected word farthest from the selected word.

### Claim 3 (depends on 1)

The mobile terminal of claim 1, wherein the controller is further configured to display a tree diagram with the selected word being positioned with respect to a first position on the tree diagram and the plurality of candidate words being positioned at different positions on the tree diagram based on how similar each candidate word is to the selected word.

### Claim 4 (depends on 1)

The mobile terminal of claim 1, wherein the controller is further configured to update a voice recognition algorithm used to convert the voice input to the text based on the selected candidate word.

### Claim 5 (depends on 1)

The mobile terminal of claim 1, wherein the controller is further configured to display a probability value next to each of the plurality of candidate words indicating how similar the plurality of candidate words are to the selected word.

### Claim 6 (depends on 1)

The mobile terminal of claim 1, wherein the controller is further configured to control the display unit to display a keyboard allowing an editing of the emphasized word when the emphasized word is selected.

### Claim 7 (depends on 1)

The mobile terminal of claim 1, wherein the controller is further configured to control the display unit to discriminately display the selected words from other words displayed on the display.

### Claim 8 (depends on 1)

The mobile terminal of claim 1, wherein the word of the text is emphasized by underlining the word.

### Claim 9

A method of controlling a mobile terminal, the method comprising:
converting voice input received via a voice receiving unit into text;
displaying, via a display unit, the text in which a word of the text is emphatically displayed if a voice recognition rate of the word is less than a preset reference value;
receiving, via a controller, a first touch selection signal indicating an emphasized word is touch selected for correction;
displaying, via the display unit, a plurality of candidate words to replace the selected word;
receiving, via the controller, a second touch signal indicating a candidate word is selected from the plurality of candidate words;
replacing, via the controller, the selected word with the candidate word and stop displaying the plurality of candidate words when the second touch signal is received;
displaying a slide bar with the selected word being positioned with respect to a first position on the slide bar;
receiving a touch and slide action on the slide bar; and
displaying candidate words at different positions on the slide bar based on the touch and slide action,
wherein as the touch and slide action slides away from the position of the selected word, candidate words having a lower similarity to the selected word are displayed, and as the touch and slide action slides toward the position of the selected word, candidate words having a higher similarity to the selected words are displayed, and
wherein the converted text is displayed in a first direction and the plurality of candidate words are simultaneously displayed in a list in a second direction perpendicular to the first direction.

### Claim 10 (depends on 9)

The method of claim 9, wherein the displaying the plurality of candidate words comprises displaying a corresponding candidate word that has a highest similarity to the selected word closest to the selected word, and displays a corresponding candidate word that has a lowest similarity to the selected word farthest from the selected word.

### Claim 11 (depends on 9)

The method of claim 9, wherein the displaying the plurality of candidate words further comprises displaying a tree diagram with the selected word being positioned with respect to a first position on the tree diagram and the plurality of candidate words being positioned at different positions on the tree diagram based on how similar each candidate word is to the selected word.

### Claim 12 (depends on 9)

The method of claim 9, further comprising:
updating a voice recognition algorithm used to convert the received voice input to the text based on the selected candidate word.

### Claim 13 (depends on 9)

The method of claim 9, wherein the displaying the plurality of candidate words further comprises displaying a probability value next to each of the plurality of candidate words indicating how similar the plurality of candidate words are to the selected word.

### Claim 14 (depends on 9)

The method of claim 9, wherein the displaying the plurality of candidate words further comprises displaying a keyboard allowing an editing of the emphasized word when the emphasized word is selected.

### Claim 15 (depends on 9)

The method of claim 9, wherein the displaying the plurality of candidate words further comprises discriminately displaying the selected word from other words displayed on the display.

### Claim 16 (depends on 9)

The method of claim 9, wherein the word of the text is emphasized by underlining the word.
