Effect of retaining syllable-boundary markers

Determine whether retaining the syllable-boundary markers produced by the Kurdish grapheme-to-phoneme converter improves the performance of the Central Kurdish text-to-speech models.

Background

The released preprocessing pipeline removes syllable-boundary markers from the grapheme-to-phoneme output before the text reaches the F5-TTS model, even though the marker symbol is present in the model vocabulary.

The review identifies the removal as a potentially consequential preprocessing choice but reports that the available evidence does not establish whether preserving the markers would improve synthesis quality. Resolving this would clarify whether the discarded prosodic information is useful for Central Kurdish speech synthesis.
