Who is going to hack together a mac widget that allows us to select text anywhere, press a shortcut key and finally get a non robotic voice outputted in a reasonable amount of time?
I am aware of the Option + Esc shortcut on osx for the onboard TTS but wow is it hard to listen to in 2026.
In System Settings, if you go to Accessibility and click "Read & Speak" in the "Vision" section, you can select a different voice using the "System voice" section. Click the "(i)" to preview your various options and even download more. Some, like "Allison (Enhanced)," sound leagues better than the default voice.
Have you tried /usr/bin/say ? Might already have something sufficient for you - there’s quite a few voices there.
