Can I run it on my hardware,
and can I ship it commercially?
40 open-source text-to-speech and speech-to-text models, checked for the hardware people actually own: Raspberry Pi 5, N100 mini-PCs and other CPU-only boxes, Apple Silicon Macs, and 8–24 GB consumer GPUs. Every license and memory figure links to its source. Speed numbers are ones we measured ourselves or quote with a link.

RTF = processing time ÷ audio length (lower is faster; <1 = faster than real time). "Unknown" means the model card or repo doesn't state it. Commercial: conditional = allowed only under conditions (revenue cap, GPL, contact vendor…), see each model page.
