Title:
VOICE RECOGNITION DEVICE AND VOICE RECOGNITION PROGRAM
Document Type and Number:
Japanese Patent JP2019066690
Kind Code:
A
Abstract:
To determine whether reference voice is included in input voice.SOLUTION: A voice recognition device 100 includes: cumulative local distance calculating means 14 for performing nonlinear matching processing of a coordinate f(t,x) of an input pattern and a coordinate z(τ,y) of a reference pattern by applying two-dimensional continuous dynamic programming to the input pattern in frequency x and time t and the reference pattern in frequency y and time τ, and calculating a cumulative local distance D(t,X,T,X); dip detection means 14 for detecting dip from the change state of D(t,X,T,X)/(T X); difference value calculating means 14 for calculating a difference value h from the change state of D(t,X,T,X)/(T X); reference pattern range detection means 14 for detecting an object range where the value of the local distance d(t,x,τ,y) is equal to or less than a second threshold value, when the difference value h is equal to or larger than a first threshold value; and voice determination means 15 for determining that the reference voice is contained in the input voice by the detection of the object range.SELECTED DRAWING: Figure 2
