    • A multi-band receiver for receiving an input signal having a frequency situated either in a first band or in a second band. The receiver comprising a mixer for combining an amplified signal having substantially the same frequency as the input signal with a periodical signal generated by a local oscillator. The mixer generates an intermediate frequency signal, the intermediate frequency signal (IF) being inputted to an IF band-pass filter. A central frequency of the band-pass filter is substantially equal to a frequency of the intermediate frequency signal. The receiver is characterized in that the central frequency of the IF band-pass filter is substantially independent of a combining mode of the amplified signal and the periodical signal, the combining mode being selected from an upper heterodyning mode and a lower heterodyning mode.
    • 一种用于接收具有位于第一频带或第二频带中的频率的输入信号的多频带接收机。 接收机包括用于将具有与输入信号基本上相同的频率的放大信号与由本地振荡器产生的周期信号组合的混频器。 混频器产生中频信号,中频信号(IF)被输入到IF带通滤波器。 带通滤波器的中心频率基本上等于中频信号的频率。 接收器的特征在于,IF带通滤波器的中心频率基本上与放大信号和周期信号的组合模式无关,组合模式选自上外插模式和下外插模式。

    • Methods and systems for sculpting synthesized speech using a graphic user interface are disclosed. An operator enters a stream of text that is used to produce a stream of target phonetic-units. The stream of target phonetic-units is then submitted to a unit-selection process to produce a stream of selected phonetic-units, each selected phonetic-unit derived from a database of sample phonetic-units. After the stream of sample phonetic-units is selected, an operator can remove various selected phonetic-units from the stream of selected phonetic-units, prune the sample phonetic-database and edit various cost functions using the graphic user interface. The edited speech information can then be submitted to the unit-selection process to produce a second stream of selected phonetic-units.
    • 公开了使用图形用户界面雕刻合成语音的方法和系统。 操作员输入用于产生目标语音单元流的文本流。 然后将目标语音单元流提交到单元选择过程以产生所选择的语音单元流,每个选定的语音单元从样本语音单元的数据库导出。 在选择样本语音单元流之后,操作者可以从所选择的语音单元流中删除各种选定的语音单元,使用图形用户界面修剪样本语音数据库并编辑各种成本函数。 编辑的语音信息然后可以被提交到单元选择过程以产生选定的语音单元的第二流。
