Multilingual TTS Is a Licensing and Hardware Minefield, Blocking Non-English Readers and Creators

Summary
Readers and creators who need natural voices outside English hit a wall: per-voice dataset licenses are inconsistent (one Spanish voice is CC BY-SA 4.0, another Apache 2.0), it is unclear whether ShareAlike obligations extend to audio generated by a model trained on that data, and users fear losing YouTube monetization or commercial rights over generated audio. On top of that, the models with good quality are too heavy for CPU-only machines (Intel Pentium, 8 GB RAM, no GPU), while the CPU-friendly ones sound less natural. There is no trustworthy source of truth on license safety and no product that guarantees commercially-safe, natural multilingual voices on modest hardware. Multilingual readers and accessibility users are effectively locked out, and no incumbent solves this — a strong niche pain with clear willingness to pay for certainty.
