Is parallel processing possible with Mozilla TTS?

So I have a raspberry pi 4 with quad core. When Mozilla TTS starts processing a string, it takes a looong time before I get the corresponding audio file.
Can I combine the power of 3 raspberry pi, somehow parallel process the tasks, and eventually wait less for the outcome of the TTS process?
Thanks and sorry for the newbie question, Iā€™m quite new to TTS and ML in general! :smile:
