Long-Form Consistency⚠ StruggledHD is not reliable for long-form Hindi cloning, with consistency problems becoming more apparent in extended content.Long-Form Consistency✗ FailedGen is not suitable for long-form Hindi cloning because voice consistency degrades during longer passages.Long-Form Consistency⚠ StruggledGen+ is not consistent for long-form Hindi content, and voice characteristics become less stable as the passage gets longer.Multilingual Output Quality✓ WorkedGen handles Hindi pronunciation and language adaptation effectively, showing strong multilingual performance.Multilingual Output Quality✓ WorkedGen+ reproduces Hindi accurately even though voice similarity is lower, so multilingual generation quality remains strong.Naturalness & Human Quality✓ WorkedGen+ sounds human-like in Hindi and remains understandable and natural, even though the flow is slightly slower than the other outputs.Naturalness & Human Quality✓ WorkedHD sounds human-like in Hindi with better flow and delivery than Gen+, plus a natural conversational rhythm.Naturalness & Human Quality✓ WorkedGen delivers natural speech flow in Hindi, with smooth pacing and pleasant, human-like delivery.Voice Match Accuracy◐ MixedIn Hindi, HD preserves speaker identity inconsistently: some sections stay close to the original voice while others sound noticeably different.Voice Match Accuracy✗ FailedIn Hindi, Gen+ preserves only about 10–20% of the original speaker identity, with most of the voice sounding significantly different from the English reference.Voice Match Accuracy◐ MixedIn Hindi, Gen retains about 50–60% of the original speaker identity, so it sounds recognizably close but not exact.
