Method of producing voice data method of playing back voice data, method of playing back speeded-up voice data, storage medium, method of assisting memorization, method of assisting learning a language, and computer program
A quick playback system which assists a user to memorize or learn a language or the like is disclosed. Voice data is sampled at a particular sampling frequency into a plurality of blocks. Fading in/out is performed on end portions of each block, and blocks are connected to each other such that end portions of respective adjacent blocks are overlapped with each other. When voice data is being played back in at an increased speed, a natural sound is played back at a normal speed such that the natural sound is superimposed on the voice data. Furthermore, a moving image corresponding to the natural sound is displayed. Equalizing may be performed on speeded-up voice data. An image moving in a scene of a natural environment may be displayed when speeded-up voice data is being played back. The speed at which the image is moved is increased in synchronization with the speed at which the voice data is played back. An image indicating a content to be memorized or learned is displayed on the left-hand side of a computer screen for a particular period, and text data indicating language information related to the image is displayed on the right-hand side of the computer screen for a particular period, thereby assisting a user to memorize or learn the language.
