mkiol.net
Speech Note Speech-to-text software;
User guide?
Also, some articles explain need for Graphics memory in excess of 10 GB(??)
Zorin OS 17 (Ubuntu 22.04)
Currently:
Lenovo ThinkStation P520 (30BF S29H00)
NVIDIA (Pegasus) GTX1650 (4GB?)
Also, 64GB DDR4 RAM
Xeon W-2125 CPU
OS installed on 2TB NVMe, 2nd 2TB NVMe and 2@ 2TB SSDs installed/available.

...more PC/power capability necessary?
Hmmm...

64GB RAM should be enough for almost anything these days on a home machine.

What specifically leads you to think it's not enough, or, to put it another way, what specific issues have you encountered?
