Learning Objective
By the end of this guide, you'll know how to clone your voice, create personalized AI-generated voice messages with variables, and send them at scale through LinkedIn using lemlist.
Why This Matters
Traditional LinkedIn outreach is saturated with cold texts and generic follow-ups. Without voice messages:
❌ Your messages blend in with hundreds of other text-based cold messages
❌ You can't convey emotion, sincerity, or personality through text alone
❌ Recording individual voice messages for each lead doesn't scale
❌ You miss opportunities to build trust faster
Using AI voice messages helps you:
✅ Stand out instantly: audio messages grab attention and feel more personal
✅ Scale personalization: record once, personalize thousands via variables
✅ Save time: no need to record every message manually
✅ Boost reply rates: voice conveys emotion and builds trust faster
Prerequisites
Multichannel Expert or Enterprise Plan (or Free Trial)
LinkedIn account connected to lemlist
Campaign with LinkedIn steps
Quiet recording space with minimal background noise
Microphone access (for voice cloning)
What Are AI Voice Messages?
AI voice messages are automatically generated audio recordings that:
Mimic your voice (via voice cloning)
Read a dynamic script with personalized variables (e.g.,
#{{firstName}},#{{companyName}})Are integrated into lemlist sequences
Are sent through LinkedIn
Step 1: Clone Your Voice
Open your campaign and add an AI Voice Message step
Go to Campaigns, then open the campaign you want to edit
In the Sequence builder, click the + icon to add a step, then select AI Voice message
Start the voice cloning flow
In the voice message editor, click Record with AI, then select Clone your voice
Follow the guidelines, then start cloning
Read the recording recommendations
Click Start cloning
Practice the recording script
You'll be given a 2-minute script to read.
Tips:
Practice reading it aloud once or twice before recording
Sound natural and confident
Speak clearly at a normal pace
Click Got it when ready.
Record your voice
Click Start recording and read the full script aloud (aim for 1:30–2:00 minutes)
💡 Pro tip: Record in a quiet room with minimal background noise for the best result.
Clone your voice
Once finished, click Clone your voice to start the AI voice generation process.
⚠️ Ensure your recording is at least 1:30–2:00 minutes long for optimal cloning quality.
Review and continue
Once your voice is ready, you can preview it. If you’re not satisfied, you can restart the process. When you’re happy, click Next.
Save and use your voice
Enter your voice name (e.g., “John’s Voice”)
Click Use my cloned voice
Your voice is now available for all AI voice message steps in your campaigns.
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}}
Example template:
Hey #{{firstName}}, I saw you're leading growth at #{{companyName}}—awesome stuff!
Just wanted to say hi, and I sent over a quick email with more details.
Preview the AI voice
Click Preview voice message for this lead
Listen to make sure it sounds natural and hits the right tone
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)
Step 3: Add to Your Sequence and Launch
Set the delay before this step (e.g., wait 2 days after LinkedIn connection)
Continue building your sequence, then launch your campaign when ready
lemlist will send personalized, voice-powered LinkedIn messages on your behalf.
How You'll Know It Worked
✓ Voice cloned successfully and available in your voice list
✓ AI voice message step appears in your sequence
✓ Preview plays correctly with your cloned voice
✓ Voice messages sent via LinkedIn when leads reach that step
✓ Leads receive audio messages in their LinkedIn inbox (desktop and mobile)
Troubleshooting
Issue: Voice clone sounds robotic or unclear
Fix: Re-record in a quieter space with better microphone quality. Speak clearly and naturally. Aim for 1:30–2:00 minutes.
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: Recording too short (under 1:30 minutes)
Fix: Read the script more slowly and naturally. Aim for 1:30–2:00 minutes for optimal cloning quality.
Optimization Tips
Record in a quiet space: Background noise degrades clone quality. Use a quiet room and a decent microphone.
Keep messages 15–25 seconds: Short voice messages get better engagement than long ones.
Personalize with variables: Always use #{{firstName}} and #{{companyName}} to make messages feel tailored.
Test on yourself first: Send a voice message to your own LinkedIn to hear how it sounds before launching to leads.
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 (e.g., after a LinkedIn connection is accepted, or as a follow-up to an email).
