Abstract

A recognizing device includes a memory and a processor coupled to the memory. The memory stores words included in a sentence and positional information indicating a position of the words in the sentence. The processor executes a process including comparing an input voice signal with reading information of a character string that connects a plurality of words stored in the memory to calculate a similarity; calculating a connection score indicating a proximity between the plurality of connected words based on positional information of the words stored in the memory; and determining a character string corresponding to the voice signal based on the similarity and the connection score.

Claims

1. A recognizing device, comprising:

a memory that stores words included in a sentence and positional information indicating a position of the words in the sentence; and

a processor coupled to the memory, wherein the processor executes a process comprising;

comparing an input voice signal with reading information of a character string that connects a plurality of words stored in the memory unit to calculate a similarity;

calculating a connection score indicating a proximity between the plurality of connected words based on positional information of the words stored in the memory unit; and

determining a character string corresponding to the voice signal based on the similarity and the connection score.

2. The recognizing device according to claim 1, wherein the memory further stores a word string in which a plurality of words are coupled and positional information indicating the position of the word string in the sentence,

the comparing includes calculating the similarity using the word string as a word, and

the calculating the connection score includes calculating the connection score using the word string as a word.

3. The recognizing device according to claim 1, wherein the memory further stores identification information for identifying a phrase so as to be associated with the phrase included in the sentence, and

the calculating the connection score includes calculating the connection score indicating the proximity between the plurality of connected words for every phrase based on the positional information and the identification information of the words stored in the memory.

4. The recognizing device according to claim 2, wherein the memory further stores identification information for identifying a phrase so as to be associated with the phrase included in the sentence, and

the calculating the connection score includes calculating the connection score indicating the proximity between the plurality of connected words for every phrase based on the positional information and the identification information of the words stored in the memory.

5. The recognizing device according to claim 1, wherein the memory further stores information indicating a probability that a second word is connected to a first word, and

the calculating the connection score includes further correcting the connection score based on the information indicating the probability that the second word is connected to the first word stored in the memory.

6. The recognizing device according to claim 2, wherein the memory further stores information indicating a probability that a second word is connected to a first word, and

the calculating the connection score includes further correcting the connection score based on the information indicating the probability that the second word is connected to the first word stored in the memory.

7. The recognizing device according to claim 3, wherein the memory further stores information indicating a probability that a second word is connected to a first word, and

the calculating the connection score includes further correcting the connection score based on the information indicating the probability that the second word is connected to the first word stored in the memory.

8. The recognizing device according to claim 4, wherein the memory further stores information indicating a probability that a second word is connected to a first word, and

the calculating the connection score includes further correcting the connection score based on the information indicating the probability that the second word is connected to the first word stored in the memory.

9. The recognizing device according to claims 1, wherein the memory further stores information concerning the suitability of the combination of word classes of the plurality of connected words, and

the calculating the connection score includes further correcting the connection score based on the information concerning the suitability of the combinations of word classes of the plurality of connected words stored in the memory.

10. A recognizing method that is executed by a computer, the recognizing method comprising:

comparing an input voice signal with reading information of a character string that connects a plurality of words stored in a memory that stores words included in a sentence and positional information indicating a position of the words in the sentence to calculate a similarity;

calculating a connection score indicating a proximity between the plurality of connected words based on positional information of the words stored in the memory; and

determining a character string corresponding to the voice signal based on the similarity and the connection score.

11. A generating device, comprising:

a memory; and

a processor coupled to the memory, wherein the processor executes a process comprising;

splitting a sentence into words;

generating positional information indicating a position in the sentence of the words split; and

storing the word and the positional information indicating the position in the sentence of the words in the memory so as to be associated with each other to generate information that is used in a recognizing device.

12. A generating device, comprising:

a memory; and

a processor coupled to the memory, wherein the processor executes a process comprising;

splitting a sentence into words;

generating a word string configured by one to a predetermined number of words which are continuous to the word split, and generating positional information indicating a position in the sentence of the words and positional information indicating a position in the sentence of the generated word string; and

storing the word and the positional information indicating the position in the sentence of the words in a memory so as to be associated with each other and storing the word string and the positional information indicating the position in the sentence of the words string in the memory so as to be associated with each other.

13. A generating method that is executed by a computer, a generating method comprising:

splitting a sentence into words;

generating positional information indicating a position in the sentence of the split words; and

storing the word and the positional information indicating the position in the sentence of the words so as to be associated with each other to generate information that is used in a recognizing device.

14. A generating method that is executed by a computer, a generating method comprising:

splitting a sentence into words;

generating a word string configured by one to a predetermined number of words which are continuous to the split words, and generating positional information indicating a position in the sentence of the word and positional information indicating a position in the sentence of the generated word string; and

storing the word and the positional information indicating the position in the sentence of the words in a memory so as to be associated with each other and storing the word string and the positional information indicating the position in the sentence of the word string in the memory so as to be associated with each other.
