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.
