Using audio variables you can share a personalized Loom video with multiple recipients without ever having to re-record. Audio variables work by identifying a name or word you wish to replace with the names of other recipients. The video will be automatically duplicated for each recipient you input, and their names will be substituted in the video audio and transcript. 

Utilizing variables can:

⏰ Save you from re-recording the same Loom again and again.
⚡️ Create customer outreach that stands out. 
🖌️ Provide a personalized experience at scale.

How to add variables

Variables replace a variable within the transcript and audio of your video and allows you to create duplicate videos with newly generated audio in your voice. If the variable you choose is mentioned in the video title then the video title will also be updated.

  1. Before adding a Variable, make sure you update your video privacy settings. Whatever your original video privacy settings are will be carried over to your duplicated videos.

    Your CSV must have a column labeled “name”. You also have the option add a column for “emails” for easy sharing. Once you import the CSV file you will be presented with a pop-up to confirm the recipients you want to import.

  1. Navigate to the variables folder that you wish to share.
  2. Click on Share via email.
  3. Here, you can enter the email addresses of the recipients. Important note: If you used a CSV file containing the recipients' emails, they should already be populated.

FAQs:

Will Variables replace all instance of a selected word in your transcript?
Yes! All instances of a selected word in your transcript will be replaced.
How does Loom use AI to create variables?
Loom generates variables using self-hosted text-to-speech models. TTS allows Loom to generate natural-sounding speech from textual inputs. When you select a variable to replace, Loom breaks it down into phonetic components. Then the components are synthesized to form the newly inputted variables you added, using the surrounding audio of your Loom to recognize and mimic your speech patterns.
Is my voice data saved anywhere?
No! The text-to-speech capabilities powering Variables do not save or store any memory of your voice patterns or use your data to improve performance. Variables uses only the surrounding audio of the Loom video being used to generate audio in the sound of your voice, which means your data remains yours! 
What steps is Loom taking to ensure someone else isn't using Variables to clone my voice?
Variables is only available to the creator of a video, so no one else can use the feature on videos you create. Variables is also limited to videos recorded on Loom. It’s not available on videos that are externally recorded and later uploaded to Loom.
How does Loom generate audio in the sound my voice?
Variables uses text-to-speech AI models that are able to generate audio in the sound of your voice.
How many copies of a video can I make? 
You can only generate 100 copies of a video at a time.
What if Variables doesn’t pronounce one of my replacements correctly? 
The text-to-speech AI models powering Variables are not always perfect. We encourage you to use the “Preview audio” function before creating your new Looms, and if something doesn’t sound right you can always remove it. We anticipate a pronunciation correction feature soon.
