杰克服务器有问题。对于starter，我会尝试重新启动音频系统，看看它是否工作：

pulseaudio --kill  
jack_control start
jack_control exit  
pulseaudio --start

如果jackd不会死，那么就杀死它。
你在Linux上吗？@Lukasz Tracewski是的，我在Ubuntu@KrishPatel“如何修复此问题？”：这不是
python
或
pyttsx
问题。删除这个问题并在@KrishPatel问一个愚蠢的问题，但是你能播放没有问题的声音吗？另外，请列出音频设备
lspci-knn | grep-iA2 audio
