PROBLEM TO BE SOLVED: To provide a conversation assist system which allows for conversation assist between a listener wearing a hearing aid and an utterer conveniently regardless of the place.SOLUTION: A conversation assist system includes a microphone 33 for collecting the voice of an utterer and converting into a tone signal, a control amplifier 40 for amplifying the tone signal from the microphone 33, and a magnetic induction loop 42 generating an alternating magnetic field, corresponding to the voice of the utterer, in a cushion sheet 10 on which the listener sits. When a hearing aid 50 with T mode worn by the listener captures the alternating magnetic field generated by the magnetic induction loop 42, voice of the utterer can be transmitted clearly to the listener. When making the cushion sheet 10 portable, conversation assist can be taken even at the place where the cushion sheet 10 is carried.SELECTED DRAWING: Figure 1
