PURPOSE: To provide an acoustic device with a singing evaluation function capable of giving a high precision singing evaluation while making the cost lower. CONSTITUTION: When a user sings a song with the accompaniment extracted from a popular song, the song is inputted to a first voice converting section 1 as voice signals and converted into a direct current level. Simultaneously, voice signals are inputted to a second voice converting section 2 as a model song corresponding to the part from which the accompaniment is extracted and are converted into a direct current level. The converted direct current levels are stored in a first level storage section 3 and a second level storage section 4, respectively. The inclination of the voice signal level as the user's song and the inclination of the voice signal level as a model song are detected by a first inclination detecting section 5 and a second level detection section 6 based on the respectively stored direct current levels. An inclination comparison section 7 compares the obtained two inclinations of the voice signal level. A point computing section 8 obtains the points of the user's song evaluation based on the comparison result and a display section 9 displays the points. |
