Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a riding toy, and in particular, the toy main body has built-in power and employs a voice recognition device, so that the toy main body can be operated and run according to voice commands. This article relates to riding toys.

[Conventional technology]

2. Description of the Related Art Conventionally, there have been ride-on toys that can be accelerated by a young child manipulating a steering wheel and stepping on an accelerator.

[Problem that the invention seeks to solve]

Children's ability to operate the steering wheel and accelerator is extremely low compared to adults, and there has been a problem with conventional ride-on toys that they cannot be operated as desired by the player. The invention was devised in view of the above problems, and includes a voice recognition means for outputting an electric signal corresponding to a voice command based on a voice command, and a voice recognition means for outputting an electric signal corresponding to the command, in a riding toy that is operated and driven by a motor. The vehicle is characterized by comprising a control means for controlling the motor, and is operated in accordance with voice commands.

[Effect]

In the present invention configured as described above, when a player issues a command by voice, the voice recognition means rejects the voice R'f4 and outputs an electric signal corresponding to the command. By controlling the motor based on this electric signal, the toy main body can be operated according to the voice commands of the ia person.

〔Example〕

An embodiment of the present invention will be described based on the drawings. Reference numeral 1 denotes a toy body whose outer shape imitates the shape of a car, and which a small child can ride astride. Inside the toy body 1 is a voice recognition device! ! ! 2, a control means 3, and a motor 4 are housed therein.

Voice recognition device! ! Reference numeral 2 outputs an electrical signal corresponding to the infant's voice command, and in this embodiment, a voice recognition device for a specific speaker employing a pattern matching method is installed. That is, a voice command is registered in advance, the input voice signal is compared with the registered voice signal, and when the voice signals match, a predetermined electrical signal corresponding to the voice command is output. It is.

Here, in order to increase B's knowledge level, for example, when registering the command "proceed", "proceed", "proceed", "proceed"...
It is configured to store the voice uttered multiple times, and output an electrical signal corresponding to "Advance" when the input audio signal is similar to any of the stored "Advance".

Note that the most suitable pattern matching method is a nonlinear matching method that uses dynamic programming to perform similarity calculations that remove time-axis distortion. Also,
It is also possible to adopt the zero-crossing method, which can be constructed at low cost, although the recognition rate is lower, or it is also possible to apply a speaker-independent speech recognition device. Although it is possible to directly connect a microphone to the voice recognition device 2, in this embodiment, a receiver 21 is connected to the voice recognition device 2, and the voice signal is wirelessly transmitted from a transmitter 22. .

That is, the talk switch 22 of the transmitter 22
When you issue a voice command to the microphone 222 while pressing 1, radio waves modulated by the voice are transmitted to the antenna 223.
The signal is emitted from the receiver 21, demodulated by the ultra-reproduced wave circuit of the receiver 21, and sent to the speech recognition device 12. The transmitter 22 can also be stored inside a helmet, allowing the child to move around freely and issue commands.
Furthermore, since the infant's mouth and the microphone are close to each other, malfunctions due to noise are drastically reduced.

The control means 3 includes a microcomputer 31, a motor control means 32, and a power supply control means 33. The microcomputer 31 performs arithmetic processing based on the output signal from the voice recognition device 2, etc., and controls the motor control means 32, etc. to control the motor 4hIP. This microcomputer 31 includes a CPU, RAM,
A one-chip microcontroller with built-in ROM etc. is desirable, but
The motor control means 32, which may be a CPU with an external memory attached thereto, drives the motors 4a and 4b based on control signals from the microcomputer 31. This motor control means 32 has four motors.

4b, forward and reverse rotation of the motor 4a,
The running speed of the toy body can also be changed by changing the rotation speed of 4b. Furthermore, in this embodiment, an independent drive system is adopted in which one motor 4 is attached to each of the left and right drive wheels, and the rotational speed of the left drive wheel motor (4a) and right drive wheel motor (4b) is controlled. By changing each independently, the direction can be changed freely. The motors 4ay and 4b are preferably DC motors that can run the toy body at a speed of about IKm per hour while carrying an infant weighing about 30 kg.Therefore, the toy body can be made to travel vertically based on the infant's voice command. The power supply control means 33 supplies the electric power of the battery 331 to the motor control means 32, and also controls the power supply voltage (
5)) is supplied after partial pressure and stabilization. The battery 331 requires a lead-acid battery of about 12V4AH, and can run for about one hour with one charge. Then, the power supply control means 33 detects a decrease in the electromotive voltage of the batch IJ-331 due to discharge, and the X source control means 33 outputs an alarm electric signal to the microcomputer 31, and the microcomputer 31 interfaces with the The system is configured to emit an alarm sound from a speaker 43 via a speaker 43. When this charge X request alarm sounds, it is necessary to charge the patch 17-331, but it is desirable to back up the voice registered in the voice recognition device with a separate power source.

Note that the infrared scanner 5 can also be connected to the microcomputer 31. That is, when the switch 512 of the beacon 51 is pressed, the multivibrator 511 is activated to drive the infrared LED 513. infrared scanner 5
It is also possible to configure the vehicle to detect infrared rays emitted from the beacon 51 and run toward the beacon 51 (tracking drive). For example, if an infant uses the transmitter 22
When the command "Come" is issued, the voice recognition device 2 recognizes that it is a "tracking run" and the microcomputer 3
It is also possible for the person 1 to utter an answer of "understood" from the speaker 43 via the inter 7 base 4 and to follow the person holding the beacon 51.

Since the interface 4 is connected to an LED 41, a blinker 42, and a speaker 43, the voice recognition device fi! It is also possible to turn on the LED 41 every time the computer 2 recognizes the voice, and also to generate a pre-understood message from the speaker 43. Also, if the input voice is unrecognizable, it will prompt you to repeat the command. For example, "Please give the command again."
It is also possible to generate sounds such as the following from the speaker 43.

Furthermore, it is also possible to automatically turn on the blinker 42 when changing direction. It is also desirable to attach safety devices such as a circuit breaker for burnout prevention 11- when the traveling motor is locked and an emergency stop device when colliding with an obstacle. What's more, if you add a demonstration tracing function that automatically runs on a pre-determined course, it would be extremely cool. ! It becomes an interesting toy. In this embodiment, the toy body is modeled after a car, but it goes without saying that it can also be shaped like a robot.

〔effect〕

The present invention configured as described above is configured such that the voice recognition device recognizes and judges the player's voice command, and the control means controls the motor in response to the voice command.
This has the added benefit of eliminating the need for remote control or steering wheel operation, allowing even young children to operate the vehicle as desired.
