Why Voice Notes Work
Most outreach is text. Voice notes are rare, which means they stand out — and the results reflect that.3× More Replies
Campaigns with a voice note step generate on average 3× more replies than equivalent text-only sequences.
Feels Human
A voice note communicates warmth, confidence, and effort that even the best-written message struggles to convey.
Harder to Ignore
Both LinkedIn and WhatsApp surface voice messages prominently in the messaging UI — the audio waveform draws the eye in a way text doesn’t.
Setting Up Your Voice Clone
Before you can use voice notes in a campaign, you need to record a voice sample so LinkInList can build your voice clone. This is a one-time setup that takes about five minutes.Open Voice Settings
Go to app.linkinlist.com/settings/voice. You’ll see the Voice Clone panel with a recording prompt.
Read the sample script
LinkInList provides a sample script designed to capture a wide range of your vocal patterns — cadence, tone, emphasis, and natural pauses. Read it aloud naturally. Don’t try to sound different from how you normally speak; the goal is to capture your authentic voice.
Record your sample
Click Start Recording and read the script. Aim for at least 2 minutes of continuous audio. Longer samples produce higher-quality clones. Record in a quiet room, close to your microphone or laptop.
Submit and process
Click Submit Sample. Your voice clone will be ready within a few minutes. You’ll receive an in-app notification when processing is complete.
Preview your clone
Once ready, click Preview Voice to hear a sample phrase rendered in your cloned voice. If it doesn’t sound right, see Re-Recording Your Voice Sample below.
Your voice data is encrypted at rest using AES-256 encryption and is never shared with third parties or used to train any external AI models. Your voice clone is exclusive to your account and cannot be accessed by any other user.
How AI Generates Each Voice Note
Once your voice clone is set up and a lead reaches a voice note step in your campaign, here’s what happens automatically:Script generation
The AI writes a personalized script for that specific lead — typically 60–90 words, designed to be delivered in under 30 seconds. It uses the same lead research that powers AI Personalization (profile, posts, company news) to make the script relevant and specific.
Voice synthesis
The personalized script is rendered as audio using your cloned voice. The AI preserves your natural cadence, pacing, and inflection as closely as possible.
Review (optional)
If Human Review is enabled on the voice note step, the generated audio appears in your review queue for you to listen to and approve before it sends.
Adding a Voice Note Step to a Campaign
You can add a voice note to any position in a campaign sequence. Most users place it as the third or fourth step, after an initial connection and one or two text messages have established some context.Open your campaign
Navigate to Campaigns, select the campaign you want to edit, and click the Sequence tab.
Select Voice Note as the step type
In the step type selector, choose Voice Note. Then select the delivery channel — LinkedIn or WhatsApp. The voice note editor will open.
Write your base script
Write the script the AI will use as a foundation for personalization. Keep it under 90 words. Include a
{{hook}} placeholder where you want the AI to insert a personalized reference, and end with a clear question.Configure personalization and review
Toggle AI personalization on and choose your depth setting. Optionally enable Human Review if you want to listen to each note before it sends.
Voice Note Best Practices
Keep scripts under 30 seconds
Keep scripts under 30 seconds
Thirty seconds of audio is roughly 70–80 words spoken at a natural pace. Leads are much more likely to play a voice note through to the end if it’s short. If your script is over 90 words, trim it — every word should earn its place.
Use a casual, conversational tone
Use a casual, conversational tone
Voice notes that sound like a formal sales pitch feel robotic and off-putting. Write your script the way you’d actually talk to someone at a networking event — relaxed, genuine, and direct. Contractions are good. Full sentences that nobody says out loud are bad.
Always end with a question
Always end with a question
Ending with a specific, easy-to-answer question dramatically increases reply rates. “Does that kind of challenge sound familiar?” or “Would it be worth 15 minutes to explore?” are both strong closes. Open-ended questions with no clear answer prompt procrastination.
Don't script every word too rigidly
Don't script every word too rigidly
The AI needs a little flexibility to personalize naturally. If your script is so tightly written that there’s no room to insert a personalized reference, the output can feel awkward. Leave one clear
{{hook}} moment for the AI to work with.Match the channel's norms
Match the channel's norms
LinkedIn voice notes and WhatsApp voice messages are both native audio formats, but the audiences and contexts differ. LinkedIn voice notes tend to work best in a professional, direct tone. WhatsApp voice messages can be slightly warmer and more conversational, reflecting the more personal nature of that channel.
Record in a consistent environment
Record in a consistent environment
Your voice clone was built from a recording in a specific environment. If the room acoustics change significantly between your original sample and how the AI renders your voice, there can be subtle inconsistencies. Consistency in your recording setup improves output quality.
Re-Recording Your Voice Sample
If you’re not satisfied with your voice clone quality, you can re-record your sample at any time to improve it.Go to Voice Settings
Navigate to app.linkinlist.com/settings/voice and click Re-record Sample.
Record a longer, higher-quality sample
For best results, aim for 3–4 minutes of audio this time. Record in a quiet space with minimal background noise, ideally using a headset or external microphone rather than your laptop’s built-in mic.
