A user friendly interface operated by the improved DTW method

This paper introduces an interface that moves its cursor by vocal commands instead of the mouse movement through fuzzy inference. Due to the short length of the vocal orders, the DTW method is applied to recognize each separate word. However, if the length of the commands is similar, the DTW method will choose a command with the least difference among the standard patterns. For example, if the command 'move extremely' is inputted, then the command 'extremely right' which is similar in length would be applied in some cases. To solve this type of error, we inferred the value of DTW error distance and the critical value to the voice length of standard patterns using fuzzy inference that leads to a command. for acceptance or rejection. If the case is ambiguous, then the system asks the user to make a decision.
