Sorry you feel that way. Readlang offers a lot for free and I plan to keep it that way, so that free users get a decent experience. As with many online services it is a bit arbitrary what is in the premium vs free plan and doesn’t necessarily correlate with marginal cost of providing the service. A year ago, neither the free plan nor the premium plan had Read Aloud. Now they both do! It’s just that the premium version is a bit better in that it gives choice.
Not all voices are available for the reason I explain here: Read aloud not working (Linux/Chrome/Brave)) - #10 by Steve
I agree that the choice of voices at the moment on many devices is not great, and falls far short of state of the art TTS in 2024. Hopefully on device local TTS voices will continue to improve over the years. And if not, maybe I’ll look into using server generated TTS to provide a better and more consistent experience across all browsers. But no promises. I have limited bandwidth and it’s hard to prioritize.
