PROBLEM TO BE SOLVED: To conduct a hearing learning with a decelerated speech speed easy to listen while listening a broadcast program in real time and to conduct the learning while a learner confirms the improvement of his hearing capability. SOLUTION: The converter is provided with plural speech speed specifying buttons 21 to 24 which respectively specify plural speech speeds that are located between a maximally reduced speech speed, that is set as a limit of the decelerated speed while one is able to listen outputted speech and the original speech speed of inputted audio signals and are capable of identifying the mutual differences with respect to other speeds, a speech speed converting means 122 which converts the inputted speech signals to audio signals having a slower speech speed, a buffer memory 14 and control means (121 and 123). When the operations of the buttons are detected, the control means control the speech speed converting means so as to convert the audio signals to have the decelerated speech speed that is preset in accordance with the setting of the buttons. The speech signals having a converted speech speed are written into the buffer memory, successively read out and are made into outputted audio signals. |
