Long-Form Consistency⚠ StruggledBecomes less consistent over longer Hindi passages, with quality fluctuations becoming more noticeable than in the English runs.Multilingual Output Quality◐ MixedCan generate Hindi speech, but the output shifts tone, pacing, and pitch enough that speaker identity preservation is weak and the clone is not suitable when the original voice matters.Naturalness & Human Quality✓ WorkedStill sounds natural, human-like, and pleasant in Hindi even though the cloned identity is weak.Voice Match Accuracy✗ FailedSpeaker identity retention drops sharply in Hindi: the report says the clone is poor in Hindi and does not closely resemble the original speaker when compared against the English reference outputs.
