Abstract: The text to speech synthesis technology and the speech modification technique are combined together to convert the lyrics to song.Firstly，the inputs of the lyrics are converted into speech with the text to speech synthesis system.Then，the melody parameters of the song are extracted from the MIDI file.At last，the melody control model is adopted to achieve the lyrics to song conversion by modifying the acoustic parameters of speech signal.Experiments demonstrate that the system can achieve 3.29 of average MOS score.

摘要： 将文语转换技术与语音修改技术相结合，实现了一个歌词到歌曲的转换系统。首先利用一个文语转换系统将输入的歌词转换为语音，同时从歌曲的MIDI文件中提取歌曲的旋律参数，最后通过旋律控制模型对语音信号的声学特征进行修改，实现由歌词到歌曲的转换。实验结果表明，系统合成的歌曲达到了3.29的平均MOS得分。
