Abstract
A voice recording/reproducing apparatus suitable for use in a language laboratory operates with a disk on which are recorded text segments comprising sentences and a table of contents containing text and sentence addresses. Automatic sensing of the division points between sentences in each of the text sections can be performed. Only the end portion of a sentence may be readily reproduced, and the division point following the sentence may be finely adjusted. Desired audio data may be quickly retrieved by rough retrieval operations, in which the time code is advanced or reversed by a large amount, followed by fine retrieval operations, in which the time code is advanced or reversed by a small amount. One of several pronunciation practice modes may be selected. A reduced reproduction speed capability allows a student to hear fine pronunciation of words with an invariant pitch.
