I study where speech loses credibility

My work explores the fracture point between AI-generated Hungarian speech and human perception. The Illusion Breaks in Hungarian is a research project examining semantic loss, timing drift, dubbing quality and speech credibility.


Through dubbing reconstruction, sync correction and ASR analysis, I examine how timing, rhythm and semantic distortion alter meaning.


Focus: speech timing, dubbing QA, ASR/TTS evaluation and Hungarian linguistic review.


Accuracy alone is not communication


Synchronization. Timing. Meaning.

We rebuild

what meaning has lost.

I study where speech loses credibility

Neural dubbing, TTS evaluation and focused Hungarian adaptation for

systems where literal accuracy is not enough.

I evaluate where meaning

survives reconstruction

My QA work focuses on native Hungarian perception and semantic stability in reconstructed speech systems.


Evaluation areas:

— semantic distortion: meaning shifted or lost during transcription

— linguistic failure: native Hungarian patterns broken or unnatural

— timing instability: speech rhythm disrupting comprehension

— cognitive correction burden: extra mental effort required to restore meaning


Accuracy is not understanding
