Long-Form Consistency◐ MixedLong-form consistency was acceptable but not fully reliable, with occasional quality fluctuations that made the output better suited to shorter multilingual content than extended narration.Multilingual Output Quality✓ WorkedThe Hindi generation remained clear and understandable, and the report says the model handled language pronunciation and adaptation effectively.Naturalness & Human Quality⚠ StruggledThe Hindi output sounded more robotic than the English runs, with weaker human-like qualities and a less natural speech flow.Voice Match Accuracy⚠ StruggledIn Hindi, the cloned voice preserved only about 15–20% of the original speaker's identity, with most of the output sounding significantly different from the source voice.
