# AI Voice Cloning FAQs
> Learn how to use AI voice cloning effectively with answers to common questions about recording, limits, and best practices.
AI voice cloning personalizes your dynamic videos by saying each viewer's name where you recorded the word "watermelon." Record a short 20-40 second Face recording, say "watermelon" once as your greeting, and Sendspark clones your voice to insert each contact's name. It works best with names and supports multiple languages.
## Key takeaways
* Use the "watermelon" variable once, as a greeting at the start of the recording, where the viewer's first name should go.
* It's designed to replace names. Other words may work but can produce unexpected results.
* You need a Face recording, with your face centered, because the background gets replaced in Dynamic Videos.
* You can generate up to 2000 videos at once, and each campaign has a total video limit based on your plan.
* Dynamic Video minutes are not rounded up, so a 45-second video does not cost a full minute.
**1) How many times can I say WATERMELON throughout the video?**
The Watermelon variable works as a greeting and you can only use it once when the recording starts.
**2) Does AI Voice cloning support other languages?**
Yes! Check [this article](/voice-cloning-with-multiple-languages)
**3) What type of recording do I need?**\
When making a recording for Dynamic Videos, you need to perform a "Face" recording. Remember that the background will be replaced, and we'll only be able to use a video where your face is centered. [Click here for more details](/record-yourself)
**4) What can "Watermelon" replace?**
Although AI Voice cloning is a flexible and versatile feature and might provide positive results, it is only meant to work with names. Any words that are not names may work well, but there's always a chance you'll get a non-desired effect.
**5) How many videos can you generate at once?**
Currently, there is a limit of 2000 videos that you can send at the same time. There's also a limit to the total number of videos that each campaign can generate based on the plan you have.
**6) How long does it take to generate 500 videos?**
It depends on how long the original video is. Using the video provided in this article as an example (an 18-second video), It takes about 20 seconds to generate 1 video.\
That means, 500 videos should take somewhere around 2 hs and 45 minutes.
**7) If I record a 45-second video, would that take a minute away from my stock?**\
No. Minutes are not rounded up. You can see your consumption under Billing: [https://sendspark.com/settings/billing](https://sendspark.com/settings/billing)
**8) I need more minutes! What can I do?**
Here's a top-secret feature to use longer videos and spend fewer minutes.

**9) What's the best way to record a video for this feature?**
Record a 20-40-second video with a short greeting: "Hey Watermelon (short silence)... I'm Dan from Tech support, and I'll be happy to help you today."
**10) How can I improve my audio quality?**
[Here is an article](/ai-voice-cloning-how-to-get-the-best-results)that will help you get the best results
**11) Some of my videos did not generate. Now what?**\
Click on ADD MORE CONTACTS to see the ones that were not generated, and click on GENERATE VIDEOS again to retry, as it's possible there was a simple network issue.\
You can also try testing one of the websites used, as it's also possible that there could be a problem with the URL.
**-Still not working?**\
Send an email to [support@sendspark.com](mailto:support@sendspark.com) with the email linked to your account, the CSV file used, and the name of the campaign.
Please note that this feature is still under development as it just came out to open beta. Your email will be analyzed and considered for future development.
