Also checked on this input — same tool, 3 other criteria

Multilingual Output Quality⚠ StruggledCross-language output quality is only partial: the Hindi script is supported and speaker identity stays decent, but pronunciation is frequently inaccurate, making the Hindi clone unreliable.Naturalness & Human Quality✓ WorkedSounds human in Hindi as well: pacing, pitch, and pauses came through well in both Hindi outputs, and neither was described as robotic.Voice Match Accuracy✓ WorkedRetains speaker identity across English-to-Hindi cloning: the Hindi output was judged a strong, consistent match to the tool's own English reference output, and the second Hindi render matched the first.
