Method and portable device for inputting characters by using voice recognition

Abstract

A method for inputting characters by using voice recognition, which is applied to a portable device, and comprises the steps of: collecting at least one external voice to convert into a voice data by a voice collection unit; receiving the voice data by a voice recognition unit; recognizing the voice data by the voice recognition unit according to a voice recognition database so as to generate a recognition result having at least one character; transmitting the recognition result to a display unit to show the recognition result in the display unit; and generating an input signal by an input unit to select a corresponding character from the at least one character of the recognition result so that only the selected character is shown in the display unit.

Claims

1. A method for inputting characters by using voice recognition, comprising the steps of: collecting at least one external voice to convert into a voice data by a voice collection unit;receiving the voice data by a voice recognition unit;recognizing the voice data by the voice recognition unit according to a voice recognition database to generate a recognition result having at least one character;transmitting the recognition result to an input column of a display unit for showing the recognition result in the input column; andgenerating an input signal by an input unit to select a corresponding character from the at least one character of the recognition result for showing the selected character in an edition column of the display unit.

2. The method for inputting characters by using voice recognition as claimed in claim 1, wherein after transmitting the recognition result to the input column and showing the recognition result in the input column, further comprising the step of: generating the input signal to select the only one character automatically when the recognition result generated by the voice recognition unit has only one character; andtransmitting the only one character to the edition column of the display unit according to the automatically generated input signal.

3. The method for inputting characters by using voice recognition as claimed in claim 1, wherein when recognizing the voice data by the voice recognition unit according to the voice recognition database, outputting a cue signal in the display unit to show that the voice data is unrecognizable if the voice recognition database has no recognition result corresponding to the voice data.

4. A portable device for inputting characters by using voice recognition, comprising: a voice collection unit for collecting at least one external voice to convert into a voice data;a memory unit having a voice recognition database;a voice recognition unit connected to the voice collection unit and the memory unit respectively, and recognizing the voice data via the voice recognition database to generate a recognition result having at least one character;a display unit connected to the voice recognition unit, and provided with an input column for receiving and showing the recognition result; andan input unit connected to the display unit, and generating an input signal to select a corresponding character from the at least one character of the recognition result for showing the selected character in an edition column of the display unit.

5. The portable device for inputting characters by using voice recognition as claimed in claim 4, wherein said input unit is a keyboard, a mouse, or a touch panel.

6. The portable device for inputting characters by using voice recognition as claimed in claim 4, wherein said input unit is able to generate the input signal only under the display unit shows the input column.
