PPROBLEM TO BE SOLVED: To provide a recognition performance estimating device capable of evaluating the performance of a word list used for voice recognition and a recognition trouble word extracting device capable of extracting a word causing recognition trouble from words included in the word list. PSOLUTION: The voice recognition performance estimating device 100 is equipped with a word similarity calculating means 104 of inputting two words which are an object word and an opponent word to calculate the word similarity; a word misrecognition score calculating means 103 of inputting the object word and word list to calculate a word misrecognition score; a mean word misrecognition score calculating means 102 of inputting the word list and calculating the mean word misrecognition score of all the words included in the word list; and a voice recognition rate estimating means 101 of inputting three elements which are the number of the words included in the word list, the mean word misrecognition score, and a candidate number narrowing-down reference value set when a solution candidate is searched for in voice recognition processing and calculating an estimated value of a voice recognition rate.
