Abstract: A learning data acquisition device or the like, capable of acquiring learning data by superimposing noise data on clean voice data at an appropriate SN ratio, is provided. The learning data acquisition device includes a voice recognition influence degree calculation unit and a learning data acquisition unit. The voice recognition influence degree calculation unit calculates an influence degree on voice recognition accuracy caused by a change of a signal-to-noise ratio, based on a result of voice recognition on the kth noise superimposed voice data and a result of voice recognition on the k?1th noise superimposed voice data, where K is an integer of 2 or larger, k=2, 3, . . .

Abstract: A moving original exposure type of copying machine comprising, an original carrier reciprocatively moving on a machine body, a group of rollers conveying a photosensitive paper synchronously with the reciprocal movement of the original carrier, an image-forming station forming an image on a photosensitive paper, the group of photosensitive paper conveying rollers including a first pair of rollers located apart from and upstream of the image-forming station, holding therebetween and conveying a photosensitive paper, and including a second and a third pairs of rollers positioned adjacent to and upstream and downstream of the image-forming station, holding therebetween and conveying a photosensitive paper, the first rollers being provided with release means whereby a photosensitive paper held by the first rollers is released when the paper passes the image-forming station.
