Translating Scene gets error whenever a letter/word changed

[demirbaris]

I'm at the beginning of Manim. I have tried to use translate option in voiceover with the following part of my code:

with self.voiceover(text=_("This circle is drawn as I speak.")) as tracker:

I got no error. But when I changed any letter, for instance deleting "I" like the following:

with self.voiceover(text=_("This circle is drawn as speak.")) as tracker:

I got the following error:

Could you help me please?

I have solved the issue. The length of the sentence matters.
