Re: ClipSpeak doesn't seem as reliable as
Not that there's the slightest thing wrong with asking about how ClipSpeak is behaving for others here, but once you have even a single counterexample for the specific problem you're having suspect something about your own ecosystem, be that a corruption in Windows 10, some weird interaction secondary to Spanish (in your case) being selected and what gets exposed to the ClipSpeak add-on, or similar.
If there is someone else reading who's also using Spanish it would be interesting to know if they've got the same issue, as that would point to some sort of issue secondary to language, but if they aren't then it points even more to something being not quite right on your machine.
But if further input suggests an issue for others that matches yours, it's the developer of the Add-On who should be the first point of contact as far as seeking a solution.

Science has become just another voice in the room; it has lost its platform. Now, you simply declare your own truth.
