macOS say (built-in)

Text to speech on your Mac offline
Zero setup, dozens of system voices, works on a plane. Dated, but it never fails.
What it costs
Free to run: it downloads once and works on the machine you already own. It costs you disk, memory and battery instead.
How it performs
A blank cell means the row does not state it, not that the answer is no. Word-error rates come from one independent harness, so they compare with each other only.
Using it
Runs on your own machine. It downloads once and then works offline: no key, no account, no per-minute cost.
These are not AI-token prices, and these engines do not answer at the hosted endpoints — 00 speaks to them from your machine, with your credentials. The speech models that do run on AI tokens are one click away on the media page.
