What Are AI Voice Messages?
AI voice messages are automatically generated audio recordings that:

Step 2: Create a Personalized Voice Message
Write your message with variables
Write a short, natural-sounding message like you'd leave a voicemail.
Use variables to personalize:
{{firstName}}{{companyName}}{{jobTitle}}
⚠️ Variables containing URLs are not supported. AI voice notes cannot propagate any custom variable whose value is a URL — those will not be read aloud. Use text-based variables only (e.g. {{firstName}}, {{companyName}}, {{jobTitle}}).
Example template:
Hey {{firstName}}, I came across your profile and really liked what you're working on.
I’d love to connect and see if there’s a way to collaborate.
You can also choose a lead from Preview voice for to test how the message sounds with personalization Previewing is free, with a limit of 15 per day.
Preview the AI voice
Select a lead in Preview voice for
Click Preview voice to generate and listen to the message
If it feels robotic or off-tone:
Edit the message to match your natural speaking style
Add punctuation for better rhythm
Try different phrasing (e.g., contractions, simpler words)
Optional: assign a specific sender
If needed, set a dedicated LinkedIn sender for this step using Sender assignment. Voice notes must be sent from a specific sender.
Optional: adjust the voice speed
If you want the generated voice to sound faster or slower, click the Voice speed icon and move the speed slider.
Optional: add variables from the editor
To insert variables directly into your message, click Add, then choose Add variable.
Step 3: Add to Your Sequence and Launch
Set the delay before this step based on where it fits in your sequence
Continue building your sequence, then launch your campaign when ready
lemlist will send personalized, voice-powered LinkedIn messages on your behalf.

Troubleshooting
Issue: Voice clone sounds robotic or unclear
Fix: Re-record in a quieter space with better microphone quality. Speak clearly and naturally.
Issue: Preview doesn't sound natural
Fix: Edit your message text to match your natural speaking style. Use contractions ("I'm" not "I am"), add commas for pauses, and simplify complex sentences.
Issue: Voice message not sending
Fix: Verify your LinkedIn account is connected in lemlist Settings → Integrations → LinkedIn. Ensure the lead has a valid LinkedIn URL.
Issue: You've reached the daily voice-message limit
Fix: Check your sending limits. The daily cap for LinkedIn messages and voice messages is managed in Settings → Sending limits
Optimization Tips
Managing Multiple Voice Clones:
Name your cloned voices clearly for easy identification.
Periodically review and remove unused voices to maintain organization.
Test different voices for various messaging tones and campaigns.
Record in a quiet space: Background noise degrades clone quality. Use a quiet room and a decent microphone.
Keep messages short: Short voice messages usually get better engagement than long ones.
Personalize with variables: Always use {{firstName}} and {{companyName}} to make messages feel tailored.
Test on yourself first: Preview the voice message on a test lead before launching to prospects.
A/B test tones: Try friendly vs. direct vs. playful messaging to see what resonates best with your audience.
Combine with other steps: Use voice messages strategically, such as after a LinkedIn connection is accepted or as a follow-up to an email.
