Resing Modeler taking too long to create a new model

I tried to create my first model using Resing Modeler, but after 18 hours of processing, the progress bar was showing only 20% complete.

My Windows 11 Home PC has Intel(R) Core™ i7-14700K (3.40 GHz) with 96GB of RAM, a 2GB graphics card NVIDIA GE Force GT1030.

The WAV file of the voice was 3.5 minutes long using as many articulations as I could think of and I set Modeler for the best quality.

The only thing I may have done wrong was the voice sample. It was a sampled song from a wordbuilding programme and I probably used too wide a range of octaves for the voice. Would this have made things too difficult for Modeler?

Is this performance what I could expect from my hardware or do you have any advice on what I could do to improve this?
