Abstract:
A pronunciation practice system, comprising:a storage medium on which image data and sound data corresponding to images is stored in a plurality of separate channels, wherein at least in part of a practice area, the sound data relating to two predetermined sounds out of a plurality of types of sound which are to be played back is allocated during storage to a first sound channel and a second sound channel as first and second sound signals, respectively; a sound feed device which feeds Sound individually to a user engaged in pronunciation practice; a sound input device which changes voices uttered by the user into a third sound signal; a switch having two input terminals and two output terminals, the first sound signal of the first sound channel and the second sound signal of the second sound channel being input to both of the input terminals in parallel way, while in a first selection state the first sound signal of the first sound channel is output from the first output terminal, the second sound signal of the second sound channel being output from the second output terminal, and in a second selection state the first sound signal of the first sound channel is output from the second output terminal, the second sound signal of the second sound channel being output from the first output terminal; an amplifier which feeds one of the first sound signals and the second sound signal fed from the first output terminal of the switch to the sound feed device; and a mixer which synthesizes one of the first sound signal and the second sound signal fed from the second output terminal of the switch with the third sound signal from the sound input device, and outputs them as a sound input signal corresponding to a displaying image by a playback device.
