Dictation recorder with speech-extendable adjustment predetermined playback time

摘要

An audio reproducer has a start-stop motor controlled by a timer in which the run-time and off-time for the motor can be each independently selected with the onset at off-time modified by a pause detector which is responsive to the interval between word groups corresponding to a normal pause in human speech. Thus in transcribing dictated material a secretary can set a suitable ratio between run-time and off-time in order to be able to type the reproduced words according to her own preference and the pause detector will modify the selected ratio of on and off time to assure that the dictation is not interrupted until a normal pause occurs in the sequence of words.
