PROBLEM TO BE SOLVED: To provide a device, a method and a program capable of estimating a fundamental frequency more approximate to interactive voice, and its storage medium. SOLUTION: The fundamental frequency estimation device is comprised of a morpheme analysis dictionary, a category name dictionary, a text analysis part, an information re-forming part, a fundamental frequency summary value estimation part, and a detail fundamental frequency estimation part. The text analysis part analyzes an inputted sentence and outputs information such as a category name different from a the part of speech in a main word of an accent phrase and a relative pitch of the accent phrase as linguistic information. The information re-forming part forms the linguistic information in a predetermined form. The fundamental frequency summary value estimation part obtains a fundamental frequency summary value every accent phrase using with a regression model. The detail fundamental frequency estimation part adapts a temporal change in the fundamental frequency obtained from the linguistic information to the fundamental frequency summary value and outputs the fundamental frequency.
