摘要： The speed of an input speech is changed without any change of the pitch of the input speech. Raw data of a speech are stored so that the speed of the speech can be modulated continuously on the basis of the raw data of the speech. In the speech speed conversion method, a speech speed conversion process for the input speech is carried out in a period designated when speech speed conversion is needed, which the speech speed conversion is not carried out in the other period. Further, in the speech speed conversion apparatus having a unit for inputting a speech, a speech speed conversion unit for changing the speed of the input speech, and a unit for supplying the output of the speech speed conversion unit as an output speech to listener's ears, the apparatus further includes a speech speed conversion switch, and a unit for outputting a speech while changing the speech speed of the input speech in a period in which the speech speed conversion switch is turned on, but for outputting a speech without any change of the input speech in the other period in which the speech speed conversion switch is turned off.

摘要： A horizontal synchronizing signal contained in a composite video signal undergoing a phase fluctuation is phase modulated and substituted for the original horizontal synchronizing signal. The phase modulation of the horizontal synchronizing signal of the input signal is effected at a phase modulation circuit and then the phase modulated signal is applied to an AFC circuit unit which has the same transfer characteristic as that of a horizontal AFC circuit of an ordinary television receiver set. The phase modulation circuit is controlled by a signal in response to a phase difference between the output of the AFC circuit unit and the original horizontal synchronizing signal. A composite video signal containing the horizontal synchronizing signal subjected to the phase modulation in this manner is applied to the television receiver set, thereby displaying a picture image free from the fluctuation.
摘要翻译：包含在经历相位波动的复合视频信号中的水平同步信号被相位调制并代替原始的水平同步信号。输入信号的水平同步信号的相位调制在相位调制电路中进行，然后相位调制信号被施加到具有与普通电视接收机的水平AFC电路相同的传送特性的AFC电路单元组。相位调制电路由响应于AFC电路单元的输出与原始水平同步信号之间的相位差的信号控制。将包含以这种方式进行相位调制的水平同步信号的复合视频信号应用于电视接收机组，从而显示没有波动的图像。
