Is the text to speech service overrrides the diacritic on Arabic words?

Hello,

I am trying the text to speech service with the following options: Language: Arabic (Egypt), Voice: Salma Neural. I tried to add a sentence with full diacritics. The output audio does not stick to the diacritics added on the words and pronounce the word with different diacritics. See, for example, the below sentence

تُشِيرُ كَلِمَةُ الْكَهْرَبِيِّ إِلَى اسْتِخْدَامِ الْكَهْرَبَاءِ، وَالتَّحْلِيلُ هُنَا يَعْنِي الْفَصْلَ.

The TTS pronounced the word "كَلِمَةُ " with wrong diacritics. Is the model totally ignore the diacritics added on the words or there is a problem with the trained model or what?

Thanks,

Ahmed Ragab
