is this is the most convenient supermarket?

Even the audio was as below but still I entered:
Is this the most convenient supermarket?

And my answer was not accepted. Come on. Is this an AI generated sentence?

Soluzione corretta:
Is this is the most convenient supermarket?

Any chance of a screen print? @rudi very cleverly noticed a very subtle difference in another case.

Unfortunately I didn't do it. I'm in "SEZIONE 5". I came across it somewhere in "CAPITOLO 140" to "CAPITOLO 190". Learning English from Italian.

It may not be clear from my first message but I meant the audio also said "Is this is the most convenient supermarket?"

Just for your information. The thing that Rudi noticed was a very subtle difference in one if the letters in the required answer. It shouldn't have mattered and it was very hard to spot but it explained why that particular answer wasnt being accepted. i.e. Duo wanted your answer to match their hard to spot typo

strange conversation here.

AI would never "generate" errors in the output, in any language. I used AI for a year now, and it's output "in terms of language and grammar and spellng" is always 100% correct - it may tell untrue things at times, but the "formulation is always correct".

So if there is sth like a double "is" in "Is this is the most convenient supermarket?" it's most probably a human error, where one started with an affirmative "This is ....." then changed that to be a question "Is this ..." and forgot to erase the other "is"

Blimey! Total word blindness! I totally missed the extra "is"!

But the audio also has "Is this is... " in it? So it's not only a typying error. Or it is if they create the audio from the text using AI tools.

The audio is TTS, so text-to-speech, so whatever text is fed in, audio will read it.
This is done offline, at creation, and stored on a cloud server.

In cases where TTS does a complete wrong reading, then some "course creator" may "override" the TTS output with a real-voice spoken recording. This used to be done by the mod of a DL forum, if someone reported the mis-pronunciation.

But they, DL, have no more forum, so no more mods, and the company rarely responds (and acts) on bugs reported via their support channels.
