VOCABULARY LEARNING FUNCTION ESTIMATION DEVICE, VOCABULARY LEARNING FUNCTION ESTIMATION METHOD AND PROGRAM THEREOF |
摘要 |
PROBLEM TO BE SOLVED: To provide a vocabulary learning function estimation device and a technique therewith allowing for approximating a vocabulary learning function to a vocabulary learning curve using a feature obtained by detecting the feature of the vocabulary learning curve different from a vocabulary burst.SOLUTION: The vocabulary learning function estimation device detects a portion where the interval of day-old when an infant child has begun to speak a new word is larger than a threshold value pbased on a vocabulary learning curve which plots a relationship between the day-old when the infant child has begun to speak the new word and the cumulative number of words the infant child has become to speak by the day-old. After smoothing the vocabulary learning curve, the vocabulary learning function estimation device detects a portion where the vocabulary learning speed of the smoothed vocabulary learning curve is the minimum. The interval of the day-old in a portion where the interval of day-old when the infant child has begun to speak the new word is larger than a threshold value pis replaced with a reference value psmaller than the threshold value p. When the interval of day-old is larger than the reference value pbefore and after the part where the vocabulary learning speed in the smoothed vocabulary learning curve, the interval of day-old is replaced with the reference value p. |
