same for me as well

Installing this package solved the challenge for me.

thanks @onyekaokonji this worked for me

I was experiencing the same issue, and that seemed to resolve that issue.

Now I received a new error (below). Do you have an idea on how to address?

This worked for me as well. Thanks a lot

Installing this package solved the challenge for me.

This worked for me as well, however the single line speak command does not work , so must set up engine and use the say command.

这个有用

Still not working for me.

try to uninstall you pyobjc then install 9.X version, see if it works

第一步：pip install pyttsx4
第二步：修改 xxxxxxx/site-packages/pyttsx4/drivers/nsss.py 文件，在头部添加代码 import objc
这样就可以正常工作了～

Personally pyttsx4 deviates quite a bit - the coqui stuff is ok. but its a bit of a overhead - this is cleaner IMHO https://github.com/thevickypedia/py3-tts (although they could do with stating its a fork)

Installing this package solved the challenge for me.

cool ! it works success on my mac machine!

I faced the same issue and it drove me crazy until I got here. Thanks, guys.

updated docs to address this and merged many bug fix PRs and published the library. if the issue persists, pls raise another issue.

Hold on @AbhashKumar55 this doesn’t look to be the same issue as the macOS one. I see you are on windows.

@AbhashKumar55 can you confirm what version of this library you are using. I feel this issue you are raising is dealt with on later versions.

Yeah i"m on my windows and the version of this library is "py3-tts 3.5" but at first i installed version "pyttsx3 2.98" and then "py3-tts 3.5"

Now i"m confused and it"s not working so should i go for "pyttsx4 3.0.15" ?
