How to Make Your First AI Voiceover, Step by Step
Musa TTS Team · · 6 min read
Making your first AI voiceover is much easier than most people expect. You do not need a microphone, a studio or any audio experience. All you need is a script and a computer.
This guide takes you from a blank screen to a finished audio file. We will use Voice Studio in Musa TTS, which comes with 46 built-in voices. The free version is all you need for this walkthrough. Set aside about half an hour for your first try. It will be faster the next time.
Step 1: Check your computer and install the app
First, make sure your computer can run the app.
- Windows: Windows 10 22H2 or Windows 11, 64-bit, a CPU from about 2015 or newer, 8 GB of memory and 5 GB of free disk space.
- Mac: Apple Silicon, M1 or newer, with macOS 13 or later, 8 GB of memory and 5 GB of free disk space.
Go to the download page, get the version for your system and install it as you would any other app. Voice Studio runs on your CPU, so you do not need a graphics card.
Step 2: Write a short script
Do not start with your full project. Start with one short paragraph, about 50 to 100 words. Short tests let you try different voices quickly.
Here is a simple script you can use:
Have you ever wondered why the sky turns orange at sunset? The answer is simple. As the sun gets lower, its light travels through more air. Blue light gets scattered away, and the warm colors reach your eyes. So tonight, step outside and take a look.
A few tips for writing for a voice:
- Write the way you speak. Use short sentences and everyday words.
- Read it out loud yourself. If you stumble, the listener probably will too.
- Spell out anything tricky. Write "five hundred dollars" if you are not sure how "$500" will be read.
We go deeper on this in our guide to writing scripts that sound natural.
Step 3: Choose a voice
Open Voice Studio and paste your script. Now pick a voice.
You can filter the list by language and preview a voice before you commit. The 46 voices cover English (US), English (UK), Spanish, French, Hindi, Italian, Japanese and Brazilian Portuguese.
Ask yourself one question: who is my listener, and who would they want to hear this from? A calm, warm voice suits a bedtime story or a wellness video. A bright, clear one suits a product demo or a quick tutorial.
Try three voices at most for now. It is easy to spend an hour listening to samples and never finish anything.
Step 4: Generate your first take
Press Ctrl + Enter, or click the generate button. The app splits your text at natural sentence breaks and starts creating the audio.
When it is finished, listen to the whole thing. Do not judge it by the first line. Listen for these things:
- Does the pace feel right?
- Does anything sound wrong or get mispronounced?
- Are there places where you want a longer pause?
Each generation is saved in History, so you can always go back to an earlier take and download it.
Step 5: Set the speed
If the voice feels too quick or too slow, change the speed. You can go from 0.5× to 2.0×.
A good rule of thumb:
- Tutorials and learning content: a little slower, around 0.9×, so people can follow along.
- Stories and calm narration: normal speed, or just below it.
- Short social videos: a little faster, around 1.1×, to keep energy up.
These are starting points, not rules. Trust your ears.
Step 6: Add pauses and control the reading
This is where a voiceover starts to feel crafted rather than automatic.
Musa TTS has Smart Text Controls, and you do not need any technical skill to use them. They are simple markers in your text, and buttons above the editor add them for you.
- Auto Pause adds natural pauses at punctuation.
- The Pause button lets you place a pause exactly where you want it.
- Say-as markers tell the voice how to read dates, times, phone numbers, units and more.
- Emphasis works by wrapping a word in asterisks, like *this*, so the voice leans on it.
Try adding a short pause before your last line. In the sunset script, a beat before "So tonight" makes the ending feel much stronger.
Step 7: Fix anything that sounds wrong
If a word comes out badly, the easiest fix is to rewrite it. Try spelling the word the way it sounds. For a name like "Siobhan", you might write "Shiv-awn".
Then generate that line again. You will not get every word right the first time, and that is normal.
Paid plans also include a Pronunciation Lexicon, so you can teach the app a word once and have it used in every project. Our guide on fixing pronunciation has more tricks.
Step 8: Export your audio
When you are happy with a take, download it as a WAV file. WAV is a high-quality format at 24 kHz that works in almost every video and audio editor.
Save it somewhere you can find it. A simple habit helps here: give each file a clear name, such as "sunset-video-narration-v2.wav", rather than leaving it with a random name.
Step 9: Use it in your project
Now you can drop the file into your editor. Free tools such as DaVinci Resolve for video or Audacity for audio both work well.
A few small touches make a big difference:
- Add quiet background music. Keep it well below the voice.
- Leave a small gap at the start and end of the audio.
- Cut long silences in your editor if needed.
- Check the volume on phone speakers as well as headphones.
Common beginner mistakes
Pasting a huge script right away. Test with a short part first, then do the full run. The free plan allows up to 1,000 characters at a time and 10,000 a day, so short tests also make your limit go further.
Choosing the voice last. Pick the voice early, because the voice affects how you write and how you pace the script.
Accepting the first take. Small changes to punctuation can change the sound a lot. Try a comma or a full stop in a different place.
Using free audio commercially. Audio from the free plan is for personal use. If the voiceover is for a monetized video, a client or a business, you need a paid plan.
What to try next
Once you are comfortable with Voice Studio, there is plenty more to explore:
- Clone a voice so the app can speak like you.
- Blend voices to make a voice all your own.
- Build a podcast with several speakers.
The best way to learn is to make something small today. A 30-second clip you finish will teach you more than a big plan you never start. Download Musa TTS and give it a try.
