TypeError: PiperVoice.__init__() missing 1 required positional argument: 'config'

When trying to initialize the model, I get the following error message:

Traceback (most recent call last):
File "/home/jedd/jarvis/jv.py", line 19, in
voice = PiperVoice(model)
^^^^^^^^^^^^^^^^^

the PiperVoice(model) syntax is wrong - it should be as follows:

PiperVoice.load(model)
