To get the best AI voice cloning results in Sendspark, record in a quiet room with no echo or reverb using the best microphone you have. Start your video with “Hi Watermelon,” leave a small pause after it, keep your volume, pace, and phrasing steady throughout, speak clearly, and make the video at least 15 seconds long.

​
Key takeaways

  • AI voice quality depends directly on your recording: record in a quiet, echo- and reverb-free room using the best microphone you have on hand.
  • Start the video with “Hi Watermelon” (which is replaced with “Hi [Name]”), and leave a small space after “watermelon” so the intro sounds seamless.
  • Maintain the same sound level, volume, and phrasing throughout, speak clearly at a moderate pace, and make the video at least 15 seconds long.
