ValueError: operands could not be broadcast together with shapes

Tried following the example in the README and got this error. Any ideas?

Process Process-1:

WAV File I used: https://drive.google.com/file/d/1-2aMp0gyxn0Km25him8C_PRV2Y8V7WMk/view?usp=sharing

Changed the sample rate of the WAV file from 24000 to 16000 and the issue went away!

I added the information about sampling rate in README.
Thanks.
