提出了一种由用户手臂运动控制的歌唱声合成器，用于娱乐工具。该系统采用磁运动传感器测量手的三维位置和手腕角度。测量值确定合成的元音样声音的响度、音高、颤音深度和音素。为了使用户合成高质量的声音，而无需长时间的训练，该系统采用了一个直观的映射从运动到声音参数。进行了两个评价实验。第一个实验表明，用户可以在平均23分钟内学会使用这种映射来控制响度和音高。第二个实验表明，在音高确定中的量化处理对于提高合成声音的感知质量是有效的。
A singing voice synthesizer controlled by user's arm motion is proposed for an entertainment tool. The system measured three dimensional position of the hand and wrist angle using magnetic motion sensor. The measured values determine loudness, pitch, depth of vibrato, and phoneme for the synthesized vowel-like sound. In order to make users synthesize high-quality sound without long training, the system employs an intuitive mapping from the motion to sound parameters. Two evaluation experiments were carried out. The first experiment revealed that users could learn to control loudness and pitch using this mapping in 23 minutes on the average. The second experiment indicated a quantization process in pitch determination to be effective to improve perceptual quality of the synthesized sound.
