Abstract

Disclosed herein is a motion sensor-based portable automatic interpretation apparatus and control method thereof, which can precisely detect the start time and the end time of utterance of a user in a portable automatic interpretation system, thus improving the quality of the automatic interpretation system. The motion sensor-based portable automatic interpretation apparatus includes a motion sensing unit for sensing a motion of the portable automatic interpretation apparatus. An utterance start time detection unit detects an utterance start time based on an output signal of the motion sensing unit. An utterance end time detection unit detects an utterance end time based on an output signal of the motion sensing unit after the utterance start time has been detected.

Claims

1. A motion sensor-based portable automatic interpretation apparatus, comprising:

a motion sensing unit for sensing a motion of the portable automatic interpretation apparatus;

an utterance start time detection unit for detecting an utterance start time based on an output signal of the motion sensing unit; and

an utterance end time detection unit for detecting an utterance end time based on an output signal of the motion sensing unit after the utterance start time has been detected.

2. The motion sensor-based portable automatic interpretation apparatus of claim 1, wherein the utterance start time detection unit detects time, at which an output signal of the motion sensing unit corresponding to motion in which the portable automatic interpretation apparatus enters a horizontal state with respect to a Y axis is input, as the utterance start time.

3. The motion sensor-based portable automatic interpretation apparatus of claim 1, wherein the utterance end time detection unit detects time, at which an output signal of the motion sensing unit corresponding to motion in which the portable automatic interpretation apparatus moves from a horizontal state to a vertical direction with respect to a Y axis is input after the utterance start time has been detected, as the utterance end time.

4. The motion sensor-based portable automatic interpretation apparatus of claim 1, further comprising a language pair change detection unit for, when inversion between sensor result values of an X axis and a Y axis occurs in the output signal of the motion sensing unit, recognizing the output signal as a language pair change command.

5. The motion sensor-based portable automatic interpretation apparatus of claim 4, wherein the language pair change detection unit performs an operation of recognizing the language pair change command after automatic interpretation between a source language and a target language has been performed at least once.

6. The motion sensor-based portable automatic interpretation apparatus of claim 1, wherein the motion sensing unit comprises one or more of an acceleration sensor and a gyro sensor.

7. The motion sensor-based portable automatic interpretation apparatus of claim 1, wherein the motion sensing unit outputs sensor result values, obtained by sensing the motion of the portable automatic interpretation apparatus in directions of X, Y, and Z axes, as the output signal.

8. A method of controlling motion sensor-based automatic interpretation, comprising:

sensing, by a motion sensing unit, motion of a portable automatic interpretation apparatus;

detecting, by an utterance start time detection unit, an utterance start time based on an output signal obtained at sensing the motion of the portable automatic interpretation apparatus; and

detecting, by an utterance end time detection unit, an utterance end time based on an output signal obtained at sensing the motion of the portable automatic interpretation apparatus after the utterance start time has been detected.

9. The method of claim 8, wherein detecting the utterance start time is configured to detect time, at which the portable automatic interpretation apparatus enters a horizontal state with respect to a Y axis, as the utterance start time.

10. The method of claim 8, wherein detecting the utterance end time is configured to detect time, at which the portable automatic interpretation apparatus moves from a horizontal state to a vertical direction with respect to a Y axis after the utterance start time has been detected, as the utterance end time.

11. The method of claim 8, further comprising:

when inversion between sensor result values of an X axis and a Y axis occurs in the output signal obtained at sensing of the motion of the portable automatic interpretation apparatus, recognizing, by a language pair change detection unit, the output signal as a language pair change command.

12. The method of claim 11, wherein recognizing as the language pair change command is performed after automatic interpretation between a source language and a target language has been performed at least once.

13. The method of claim 8, wherein detecting the motion of the portable automatic interpretation apparatus is configured to output sensor result values, obtained by sensing the motion of the portable automatic interpretation apparatus in directions of X, Y, and Z axes, as the output signal.
