The player piano provides a string-striking mechanism including a hammer driven by corresponding one of eighty-eight keys, and a photo sensor is provided in the vicinity of and also positioned to face with the predetermined member of this string-striking mechanism to be rotated responsive to a key-depression. This photo sensor outputs a signal which is varied in response to a distance of the predetermined member therefrom, so that the output thereof may have a peak value. Based on the peak value, first and second output values are respectively calculated, wherein these values corresponding to the predetermined two measuring points arranged between the photo sensor and the predetermined member are outputted from the photo sensor before and after the peak value respectively. On the basis of the distance between two measuring points and passing time to be passed when the sensor output is varied from the first output value to the second output value, a string-striking velocity of said string-striking mechanism representing a performance state of the play piano is to be computed. Thus, fixation and adjustment of the sensor can be made easily, thereby the string-striking velocity of the hammer can be sensed accurately.

Base insulating layers are formed on a support substrate having a conductive property. The support substrate is etched, to form support substrate board and a plurality of conductive portions in a suspension board. The holding piece and the conductive portions constitute a shape determination unit. The conductive portions have first to fifth conductive portions. The third and fourth conductive portions are spaced apart from each other, and the fifth conductive portion is formed between the third and fourth conductive portions. The first and second conductive portions are respectively formed integrally with one end and the other end of the fifth conductive portion. It is determined whether the first and second conductive portions in the shape determination unit are connected electrically to each other. And it is determined whether the first and third conductive portions are connected electrically to each other.

A voice recognition device is provided with a sentence selecting unit for selecting sentences each having a predetermined number or less of acoustic units as sentences to be recognized from candidates for the sentences to be recognized. According to an exemplary embodiment, the sentence selecting unit may define the selected sentences as sentences to be recognized. According to another exemplary embodiment, when a candidate for a sentence to be recognized has a number of acoustic units exceeding the predetermined number, one or more acoustic units may be trimmed from the candidate, and the trimmed candidate may be defined as one of the sentences to be recognized.
