🎙️ Create emotional voice clones: a practical guide + character script pack

This guide is designed to help you record emotionally expressive source audio for voice cloning in Synthesia. It includes both practical guidance and character scripts to show how your performance choices directly shape the emotional tone of the voice clones you create. Each script represents a specific scenario and emotional state (angry, upset, urgent) to help you intentionally amplify your delivery.

💡 It’s not what you say, it’s how you say it

You don’t have to follow the scripts exactly! The words you say in your recording aren’t as important as how you say them. In fact, you could read the default voice cloning script in an angry way and get an angry voice clone. The purpose of these scripts is to make it easier for you to get into character and hit the emotional tone you’re looking for.

🎭 Tips for getting into character

Getting into character is usually the most awkward part of this process, especially for non-actors. These quick techniques will help you feel the emotion instead of trying to “sound” emotional.

1. Answer three questions out loud (yes, really)

Before recording, say these out loud in your own words:

• Who am I?(customer, manager, employee, leader, etc.)
• Who am I talking to?(support agent, direct report, leadership)
• What do I want from them right now?(a fix, to take action, sympathy)

Once you know what you want, the emotion will follow more naturally.

2. Picture a real moment

❌ Don’t think: “I need to sound angry.”

✅ Do think:

• “I’ve been ignored for three weeks.”
• “I’m about to miss a deadline and leadership is watching.”
• “I just got bad news that I wasn’t prepared for.”

Image yourself in a specific situation to trigger more believable delivery than chasing the concept of an emotion.

3. Adjust your body

Your physical state heavily affects your voice, so adjust your posture and breathing pattern in line with the emotion you’re trying to embody.

Try this before performing:

• Angry / Mean: tighten your jaw, lean slightly forward
• Upset / Disappointed: drop your shoulders, slow your breathing
• Urgent: sit upright, lean in, shorten your breaths

4. Speak to someone, not at the screen

Imagine a real person in front of you:

• someone who annoyed you
• someone you respect
• someone you’re disappointed in

If you catch yourself “reading,” restart. Conversational delivery always sounds more emotional than perfect reading.

5. Let silence do some of the work

You don’t need to fill every gap; silence is part of the performance!

Short pauses can add tension when you want to convey anger, add weight when you’re disappointed, and add authority if you’re delivering with urgency.

6. Exaggerate slightly (it won’t sound exaggerated later)

A good rule of thumb:

If it feels just a little over the top while recording,

it will usually sound just right in the voice clone.

Subtle performances might flatten out once processed.

📌 Overall, to get the most out of these scripts:

• Practice them out loud and record several takes to get comfortable before recording your final submission for voice cloning. Listen back and ask: does the emotion come through clearly?
• Slightly exaggerate your performance to help the voice cloning model better preserve the emotional tone.
• Let pauses and silence do some of the work. Natural pauses add realism and emotional weight.
• Remember: you’re speaking to someone, not reading a script. Avoid over-enunciating or reading mechanically.

🎙️ Recording best practices:

• Use the highest quality microphone available to you and avoid using your laptop microphone if possible.
• Record in a quiet space to minimize background noise and echo.
• Maintain the same distance from your mic for the entire recording.

🎭 Character scripts

😡 Angry / Mean (disgruntled customer)

Look, I don’t even know where to start. I’ve been on hold for 45 minutes. Forty-five. Do you even know how insane that is? And this isn’t even the first time—I’ve called three times this week and still haven’t gotten a straight answer from anyone.

I’m beyond frustrated. I ordered a product over three weeks ago. THREE WEEKS. It was supposed to arrive in three to five business days. Not only did it not show up, I got an email saying it was delivered—but it wasn’t. No package. No knock. Nothing.

…And your tracking system? Useless. It just says “delivered.” Delivered WHERE? Mars?!

I’m done being patient. If this isn’t resolved today, I am DONE with your company. This is completely unacceptable!

😞 Upset / Disappointed (someone processing bad news)

I got the message earlier today…

I’ve been sitting with it for a while now, trying to figure out what to say…or how I’m even supposed to feel about it.

I’ll be honest…

…this isn’t what I was expecting.

I mean, I really thought things were going in a different direction…

I put a lot of time into this. A lot of effort…and I genuinely believed it mattered.

It feels like the rug’s been pulled out from under me; like something I was counting on is suddenly gone…

I understand that decisions have to be made, and that sometimes things just…don’t work out.

But that doesn’t make it any easier to hear.

I’m disappointed. Not just because of the outcome…but because I really hoped for more.

I’ll adjust. I mean, I always do…

I just need a little time to process this and figure out what comes next, I guess…

😤 Urgent (intense manager, under pressure)

Okay. I need everyone’s attention for a moment, because this is time-sensitive.

The deadline for this deliverable hasn’t changed—even though the circumstances most definitely have.

We’re still expected to ship by end of day, and right now, we are not on track.

I’ve reviewed what’s been completed and I need to be very clear: this absolutely cannot slip.

I don’t need perfection. I need progress. I need you to execute. And I need it now.

If something is blocked, say it. If you need a decision, escalate it. Waiting and hoping this resolves itself is not an option.

We have the next two hours to course-correct, and every minute matters.

I expect updates. I expect ownership. And I expect us to move with maximum urgency from this point forward.

Let’s focus and get this across the line.

You don’t need acting experience to get great results here. Trust the process, experiment with a few takes, and notice how much difference performance alone can make in your voice clones.
