装置。 A switch that selectively guides the video signal from the video intermediate frequency circuit and the text synchronization signal from the text synchronization signal generation circuit to the synchronization separation circuit, and the output of the synchronization separation circuit and the output of the horizontal oscillation circuit are not in a synchronous relationship. In a teletext receiver equipped with a synchronization detection circuit for detecting and an audio cancellation circuit for erasing audio output by the output of the synchronization detection circuit, a detection means is provided for detecting that a mode in which only text information is displayed is selected. . A voice erasing device for a teletext receiver, characterized in that the voice erasing circuit is activated by the output of the detection means to erase the voice.
