Abstract

A dimension measurement system is provided. The dimension measurement system includes a speech I/O device fit in an ear canal of a worker, generating a voice signal from vibration in the air emitted from an eardrum of the worker and propagated inside the ear canal, and outputting the voice signal and an information processing device realizing a speech recognition function recognizing a measurement value of a dimension of an object from the voice signal that the speech I/O device output and a judgment function judging if the measurement value satisfies a reference value of the object.

Claims

1. A dimensional measurement system comprising:

a speech I/O device fit in an ear canal of a worker, generating a voice signal from vibration in the air emitted from an eardrum of the worker and propagated inside the ear canal, and outputting the voice signal; and

an information processing device including a memory unit, the memory unit storing term definition information associating predetermined term with type and unit of dimension measurement value, the information processing device that is configured to;

recognize a measurement value of a dimension of an object from the voice signal that the speech I/O device output;

judge if the measurement value satisfies a reference value of the object;

recognize a word included in the voice signal,

when a predetermined term included in the term definition information that is read from the memory unit corresponds to the recognized word, specify a measurement value that is recognized after the recognized word by a type and unit of dimension measurement value associated with the predetermined term corresponding to the recognized word,

recognize an order of recognized measurement values when the predetermined term in the read term definition information is not included in the voice signal; and

specify a measurement value by the type and unit of a dimension measurement value corresponding to the order of the measurement value, using information associated an order of measurement values, and types and units of dimensions.

2. The dimensional measurement system as set forth in claim 1, wherein

the information processing device transmits a measurement value to the speech I/O device, and

the speech I/O device outputs by voice the transmitted measurement value.

3. The dimension measurement system as set forth in claim 1 or 2, wherein the information processing device is further configured to:

recognize the number of digits of the recognized measurement value of the object; and

,

output by voice an error result through the speech I/O device when the number of digits of the recognized measurement value is different from the number of digits according to the specification of the object.

4. The dimensional measurement system as set forth in claim 1 or 2, wherein

the information processing device is configured to transmit judgment results of the judgment to the speech I/O device, and

the speech I/O device outputs by voice the transmitted judgment result.

5. The dimensional measurement system as set forth in claim 1 or 2, further comprising a digital micrometer or digital caliper measuring the dimensions of the object and wirelessly transmitting the measurement values.

6. The dimensional measurement system as set forth in claim 1 or 2, wherein the information processing device further comprises an ID reading means for reading identification information relating to the object.

7. The dimensional measurement system as set forth in claim 1 or 2, wherein

information depicting the reference value is transmitted to the information processing device from a control computer managing the specifications of the objects, and

the information processing device is further configured to:

transmit the judgment result to the speech I/O device,

receive information depicting the acceptance of the measurement value received from the speech I/O device, and

transmit the accepted measurement value to the control computer.

8. An information processing device connected to a speech I/O device fit in an ear canal of a worker, generating a voice signal from vibration in the air emitted from an eardrum of the worker and propagated in the ear canal, and outputting the voice signal, the information processing device comprising:

a memory unit that stores term definition information associating predetermined term with type and unit of dimension measurement value; and

a processing unit that is configured to;

recognize a measurement value of a dimension of an object from the voice signal that the speech I/O device output; and

,

judge if the measurement value satisfies a reference value of the object;

recognize a word included in the voice signal,

when a predetermined term included in the term definition information that is read from the memory unit corresponds to the recognized word, specify a measurement value that is recognized after the recognized word by a type and unit of dimension measurement value associated with the predetermined term corresponding to the recognized word,

recognize an order of recognized measurement values when the predetermined term in the read term definition information is not included in the voice signal; and

specify a measurement value by the type and unit of a dimension measurement value corresponding to the order of the measurement value, using information associating an order of measurement values, and types and units of dimensions.

9. The information processing device as set forth in claim 8, wherein the processing unit further configured to:

recognize the number of digits of the recognized measurement value of the object; and

,

output by voice an error result through the speech I/O device when the number of digits of the recognized measurement value is different from the number of digits according to the specification of the object.

10. The information processing device as set forth in claim 8 or 9, further comprising an ID reading means for reading identification information relating to the object.
