Abstract

PURPOSE:To improve the operability by providing a discriminating part for comparing an analytical pattern with a standard pattern and outputting a cursor control command corresponding to the standard pattern having the highest degree of similarity. CONSTITUTION:An inputted sound signal 1 is synchronized with a timing signal which has been generated by a timing signal generating part 2 at a time interval prescribed in advance, and brought to analytical processing in a voice analyzing part 3. An analytical pattern is sent to a discriminating part 5, and its degree of similarity to each standard pattern which has been stored in a standard pattern storage part 4 is calculated. The calculation of the degree of similarity is executed by a distance calculation of a result of the analysis shown as a vector, and the standard pattern, and a result of the discrimination is outputted as a cursor control command 6 corresponding to the standard pattern having the highest degree of similarity.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in a device for controlling the position of a cursor on the screen of a display input device such as a CRT display.

(Prior Art and its Problems) Conventional devices for controlling the position of a cursor on a screen include those using cursor movement keys and those using a mouse.

Those using cursor movement keys do not require special hardware to operate, as the cursor movement keys are provided as part of the keyboard keys for inputting data or text. This prevents smooth data and text input operations.

-Operation using a mouse is intuitive, but when inputting data or text from a keyboard, you have to take your hands off the keyboard to operate the mouse, so the keyboard operation is similarly smooth. is prevented from being carried out.

Cursor movement is the most frequently used screen control, and it is important to be able to perform this operation smoothly.

(Object of the Invention) An object of the present invention is to realize a cursor control device that facilitates keyboard operations and has good operability by using voice input as a means of controlling cursor movement.

(Structure of the Invention) A cursor control device according to the present invention includes a timing signal generation section that generates a control timing signal at predetermined time intervals, and an input audio signal that analyzes an input audio signal at the time when the timing signal is generated. a voice analysis section that outputs analysis patterns; a standard pattern storage section that holds a plurality of standard patterns corresponding to a plurality of cursor control commands; and a standard pattern storage section that compares the analysis pattern with the standard pattern in the standard pattern storage section and determines the degree of similarity. and an identification unit that outputs a cursor control command corresponding to a standard pattern with a high standard pattern.

(Principle of the present invention) When moving a cursor using voice input, it is necessary to obtain the result of the voice input at high speed.

Therefore, conversion from voice input signals to cursor control signals is performed by continuously recognizing the voice input from time to time, without dividing the voice signal into vocal units such as words. .

The principle of the present invention will be described below, taking as an example the case where the vertical and horizontal movement of the cursor is controlled.

The movement of the cursor needs to be controlled continuously, but it can be done continuously by assigning sounds that can be emitted continuously to each of the movements ``Up'', ``Down'', @Left'', and ``Right #l''. For example, as shown in Figure 2 (a), the vowel 10/ is placed above, the vowel /e/ is placed below, and the vowel /a is placed under %.
/, "right" is the vowel /u/'c, and the input voice is sampled at regular time intervals, and at each time it is 10/, /e/, /a/, /u/. It is possible to determine which is the case and move the cursor based on the result. When you say ``oak'' as shown in Figure 2 (bl), the cursor moves to 1 up'', 'up', 'up', 'up' as shown in Figure 2 1cl.

Move 1 left”, ’left”. In this way, the operator can quickly move the cursor to an arbitrary position by changing the type and duration of vowel pronunciation without performing manual operations.

In the above example, the vowel assignments are 1 upper, lower, left,
The reading of “right” is /jou-ge@S!・y!!
It was taken from /.

(Example) Hereinafter, a detailed explanation of the configuration of the present invention will be given based on an example shown in FIG.

The input audio signal 1 is analyzed in the audio analysis section 3 in synchronization with a timing signal generated by the timing signal generation section 2 at predetermined time intervals. As the analysis process here, any method such as autocorrelation analysis or spectrum analysis can be used. The analysis pattern as the analysis result is sent to the identification section 5, where it is stored in the standard pattern storage section 4.
The degree of similarity with each standard pattern stored in is calculated. A standard pattern is prepared for each cursor control command, for example, in the case of the above-mentioned up/down/left/right movement control, the standard pattern is 10/.

Four types of standard patterns are prepared corresponding to /e/, /a/, and /u/. A standard pattern may be created by having each operator make a registered utterance, or a standard pattern may be created by having the pattern tS common to all operators. The degree of similarity is calculated by calculating the distance between the analysis result expressed as a vector and the standard pattern, but the distance can be defined arbitrarily.

The identification result is output as a cursor control command 6 corresponding to the standard pattern with the highest degree of similarity.

Note that the cursor control command is output in synchronization with the timing signal, but when not being uttered.

When the analysis result is not similar to any standard pattern (the degree of similarity is small), such as when utterance is erroneous, no cursor control command is output.

(Effects of the Invention) As described above, according to the present invention, it is possible to continuously obtain cursor movement control commands in synchronization with a timing signal without manual operation, so cursor movement control with good operability is achieved. Realized.
