Hello,
I'm trying to benefit from Pronunciation Assessment Service in my educational app. The reference text sent to Pronunciation Assessment Service has full diacritics, however, no matter how wrong the diacritics pronunciation is in the audio, the Pronunciation Assessment Service keeps sending back high Accuracy Score for the mis-pronounced words with diacritics.
It looks like Arabic diacritics not being taken into consideration during the assessment process.
Is this behavior by design?
Or we can expect full Arabic diacritics support when the language is officially released? (I believe it is for public preview right now).
Thank you,

2023-07-10T22:15:52.3966667+00:00 Thank you Vasavi for reaching out,
The following sentence was sent to Pronunciation Assessment service with the correct diacritics:
رَدَّتْ سَلْمى: أَنا مَشْغولَةٌ بِاللَّعِبِ.
However, the accompanied audio has totally wrong diacritics pronunciation, yet the resulting score was very high 90%+.

The locale used is "ar-sa".
Moreover, I recorded two audio files, one with correct pronunciation and the other with incorrect pronunciation.
You can get the incorrect pronunciation audio from here.
The correct pronunciation audio is here.
The pronunciation result file for the incorrect pronunciation can be found here.
