    • A teaching machine is used with a card to pose a question to a user of the machine and to accommodate both a first case wherein a voice signal is audibly reproduced before the user enters his answer to the question into the machine and a second case wherein a voice signal is audibly reproduced after the user enters his answer into the machine. The machine includes a signal reproducer that cooperates with a card upon which a control signal, a correct-answer signal encoding a correct answer to the question and a voice signal are recorded and that reproduces the recorded signals from the card. A user of the machine enters a test answer to the question into the machine via a keyboard. A first memory responds to the correct-answer signal as reproduced by the signal reproducer for storing the correct answer, and a second memory responds to the keyboard for storing the test answer. A comparator responds jointly to the first and second memories for comparing the correct answer and the test answer and producing an output signal in accordance with the comparison. Lamps responsive to the comparator output signal indicate whether or not the test answer is correct. An audio channel jointly responsive to the control signal and the voice signal as reproduced by the signal reproducer audibly reproduces the voice signal before making the comparison in the first case and after making the comparison in the second case.
    • 教学机器与卡一起使用以向机器的用户提出问题,并且既适用于在用户将问题回答到机器中之前将语音信号可听地再现的第一种情况和第二种情况,其中 在用户将他的答案输入机器后,语音信号可以被再现。 该机器包括信号再现器,与信号卡协同操作,在该卡上控制信号,对问题的正确答案和声音信号进行编码的正确答案信号,并从卡中再现记录信号。 机器的用户通过键盘将问题的测试答案输入机器。 第一存储器响应由信号再现器再现的用于存储正确答案的正确答案信号,并且第二存储器响应键盘存储测试答案。 比较器共同响应第一和第二存储器,用于比较正确答案和测试答案,并根据比较产生输出信号。 响应于比较器输出信号的灯指示测试答案是否正确。 在第一种情况下进行比较之前和在第二种情况下进行比较之后,由信号再现器再现的控制信号和语音信号共同响应的音频信道可以再现声音信号。
