GENERATION DEVICE, RECOGNITION SYSTEM, AND GENERATION METHOD FOR GENERATING FINITE STATE TRANSDUCER
First Claim
1. A generation device comprising:
- a receiving unit that receives a model representing correspondence between one or more phonetic symbols and one or more words; and
a generating unit that generates a first finite state transducer based on the model, the first finite state transducer at least including, as outgoing transitions from a first state representing transition destination of a first transition which has a first phonetic symbol of a predetermined type as input symbol,a second transition that has a second phonetic symbol, which is different than a particular symbol representing part or whole of input symbol of the first transition, as input symbol, anda third transition that has a third phonetic symbol, which represents the particular symbol or silence, as input symbol.

Abstract
A generation device includes a receiving unit and a generating unit. The receiving unit receives a model representing correspondence between one or more phonetic symbols and one or more words. The generating unit generates a first finite state transducer based on the model, the first finite state transducer at least including, as outgoing transitions from a first state representing transition destination of a first transition which has a first phonetic symbol of a predetermined type as input symbol, a second transition that has a second phonetic symbol, which is different than a particular symbol representing part or whole of input symbol of the first transition, as input symbol, and a third transition that has a third phonetic symbol, which represents the particular symbol or silence, as input symbol.

11. A recognition system comprising a generation device and a recognition device, wherein
the generation device includes a receiving unit that receives a model which converts one or more phonetic symbols into words, and a generating unit that generates a first finite state transducer based on the model, the first finite state transducer at least including, as outgoing transitions from a first state representing transition destination of a first transition which has a first phonetic symbol of a predetermined type as input symbol, a second transition that has a second phonetic symbol, which is different than the first phonetic symbol, as input symbol, and a third transition that has a third phonetic symbol, which represents the first phonetic symbol or silence, as input symbol, and the recognition device includes a searching unit that refers to the first finite state transducer and recognizes a word corresponding to an input speech.

12. A generation method for generating finite state transducer, comprising:
-
receiving a model representing correspondence between one or more phonetic symbols and one or more words; and generating a first finite state transducer based on the model, the first finite state transducer at least including, as outgoing transitions from a first state representing transition destination of a first transition which has a first phonetic symbol of a predetermined type as input symbol, a second transition that has a second phonetic symbol, which is different than a particular symbol representing part or whole of input symbol of the first transition, as input symbol, and a third transition that has a third phonetic symbol, which represents the particular symbol or silence, as input symbol.
