摘要： A method and apparatus to disturb a voice signal by attenuating and masking the voice signal are provided. The method includes; receiving a voice signal from a wired or wireless network; obtaining a masked voice signal by dividing the received voice signal into a plurality of segments of the same size; outputting the received voice signal and receiving a feedback signal of the output voice signal; obtaining an attenuated voice signal by performing a first sound attenuation operation on the feedback signal; and combining the attenuated voice signal and the masked voice signal and outputting the result of the combination as disturbing sound.

摘要： A speech synthesis method, in which speech units are concatenated using a DB, wherein the speech units to be concatenated are determined and divided into a left speech unit and a right speech unit. The length of an interpolation region of each of the left and right speech units is variably determined. An extension is attached to a right boundary of the left speech unit and an extension to a left boundary of the right speech unit. The locations of pitch marks included in the extension of each of the left and right speech units are aligned so that the pitch marks can fit in the predetermined interpolation region. The left and right speech units are superimposed after fading out the left speech unit and fading in the right speech unit. Accordingly, a determination of whether extra-segmental data exists or not is made, and smoothing concatenation is performed using either an interpolation of existing data or an interpolation of extrapolated data depending on the result of the determination.

摘要翻译： 一种语音合成方法，其中语音单元使用DB级联，其中要连接的语音单元被确定并分成左语音单元和右语音单元。 可变地确定左右语音单元中的每一个的内插区域的长度。 扩展部分附加到左侧语音单元的右边界，并且扩展到右侧语音单元的左边界。 左右声音单元的延伸中包括的音高标记的位置对准，使得音高标记可以适合于预定的插值区域。 左右语音单元在淡出左侧语音单元并在右侧语音单元中衰落之后叠加。 因此，确定是否存在分段数据是否存在，并且根据确定的结果，使用现有数据的插值或外插数据的插值来执行平滑级联。
