How to Use AI Voice on TikTok

The robotic voice narrating everything from day in the life videos to ridiculous skits is one of the most recognizable sounds on TikTok, and using it is easier than you think. This powerful feature, known as Text-to-Speech, can make your content more engaging, accessible, and fun. This guide will walk you through exactly how to add the AI voice to your videos, share creative strategies for using it effectively, and offer tips to make your content stand out on the For You Page.

What is the TikTok AI Voice (And Why Should You Use It)?

The TikTok AI Voice is a native feature called Text-to-Speech (TTS) that automatically converts any text you add to a video into an audio narration. What started as an accessibility feature has grown into a massive creative tool used by millions of creators to add personality and context to their videos without ever having to record their own voiceover.

So, why is this computer-generated voice so popular?

• It adds a layer of humor and personality. The deadpan delivery of an AI voice narrating chaotic or emotional events is a classic comedic formula that just works. It creates an entertaining contrast that captures attention.
• It makes content more accessible. For users who are scrolling with the sound off or who are hard of hearing, the combination of listening to the AI voice and reading the on-screen text makes the content much easier to follow.
• It’s great for camera-shy creators. Not everyone feels comfortable recording their own voiceover. Text-to-Speech lets you add detailed commentary and storytelling to your videos without having to worry about your speaking voice, background noise, or expensive microphones.
• It’s part of the TikTok language. The various AI voices have become iconic. Using them signals to viewers that you understand the platform's culture and trends, making your content feel more native and relatable.

How to Use the TikTok Text-to-Speech AI Voice: Step-by-Step

Adding the AI voiceover is baked right into the TikTok editing process. Once you get the hang of it, you’ll be doing it in seconds. Here's a simple breakdown of how it’s done.

Step 1: Record or Upload Your Video

First, open the TikTok app and tap the plus icon (+) at the bottom of the screen to start a new project. You can either record a new video directly in the app or upload one (or multiple clips) from your phone’s camera roll. Once your footage is in the editor, trim your clips and make any other initial edits. When you're ready to add text, tap the red Next button to proceed to the main editing screen.

Step 2: Add Your Text

On the right side of the editing screen, you’ll see a menu with several icons. Tap the “Aa” (Text) icon to add a new text box to your video. Type in the phrase or sentence you want the AI voice to narrate. Don't worry about getting the timing perfect just yet, we'll adjust that in a later step. Once your text is typed, you can customize the font, color, and add a background highlight to make it pop.

Step 3: Activate the Text-to-Speech Feature

This is the most important part. After you’ve typed your text, tap on the text box one more time to bring up a small options menu. You'll see choices like "Edit," "Set duration," and - the one we’re looking for - "Text-to-Speech." It looks like an icon of a person's head with sound waves coming out of it.

Tap on that icon. TikTok will process the text, and you’ll instantly hear it spoken aloud.

Step 4: Choose Your Voice

Once you’ve activated Text-to-Speech, you’ll be prompted to select a voice. TikTok regularly updates these options, but you'll typically find a variety to choose from, often labeled with names like "Jessie" (the classic female voice), "Trickster" (a deep, dramatic voice), "Serious" (a male news-reporter style voice), or even character voices like Stitch or Rocket Raccoon.

Tap through the different options to preview how they sound with your text. The voice you choose can dramatically change the tone of your video, so pick the one that best fits the vibe you’re going for.

Step 5: Set the Duration and Timing

Now, you need to sync the audio with your video. For each text box you’ve created, you can control when it appears on screen and for how long.

• Tap on your text box.
• Select "Set duration."
• A timeline of your video will appear at the bottom of the screen. Drag the left and right edges of the red highlight bar to adjust when the text appears and disappears. The AI voice will only play during the time the corresponding text is visible on screen.

This is where breaking up your narration into multiple, smaller text boxes really helps. It gives you precise control, allowing you to time each spoken phrase to specific actions in your video.

Step 6: Final Adjustments and Post

Listen back to your video to make sure the audio timing is right. You might need to adjust the duration of a few text boxes to give the AI voice enough time to finish speaking before the next clip starts. Once everything sounds and looks good, adjust the volume of the original video sound or any music you’ve added. Finish your post by adding a caption, relevant hashtags, and then hit Post. You’re done!

Creative Ways to Use AI Voice to Make Your TikToks Go Viral

Just knowing how to use the feature isn’t enough. The most successful creators use Text-to-Speech strategically to tell better stories. Here are some popular formats and ideas to get you started.

1. Mundane Task Narration

This is a classic for a reason. Use the deadpan AI voice to narrate a totally normal routine, like making your morning coffee, tidying your room, or packing your lunch. The contrast between the dramatic or overly serious narration and the simple, everyday task is comedy gold.

2. "Get Ready With Me" or "Day in the Life" Videos

Walk your audience through your routine by adding narration to each step. Instead of you speaking over the video, let the TTS voice explain your skincare products, what you’re eating for breakfast, or the tasks you have scheduled for the day. It’s a low-effort way to make a simple vlog more polished and engaging.

3. Informational Content & Tutorials

Are you explaining a useful tip, a complex idea, or showing a quick recipe? The AI voice can deliver clean, clear instructions that are easy for anyone to follow. This is particularly effective for how-to content where the visual steps are the main focus, and the voiceover simply provides helpful context.

4. Pet and Animal Voiceovers

One of the most beloved trends on TikTok is giving animals an inner monologue. Record your pet doing something funny, like sleeping in a weird position or staring at a wall, and use the AI voice to narrate their "thoughts." It's incredibly simple and almost always entertaining.

5. Storytelling Vlogs

Share a funny, frustrating, or interesting story from your day using the AI voice as the narrator. This format lets you compile a series of short clips and tie them all together with a cohesive narrative. By using the AI voice, it feels less like a personal diary and more like an entertaining short story for a broad audience.

Using Third-Party Apps for Even Better AI Voices

While TikTok's built-in Text-to-Speech is fantastic for most creators, its voice options can feel a bit limited. If you want more variety, custom voices, or the ability to clone your own voice, you can use a third-party application.

Apps like CapCut (TikTok's sister editing app), offer their own extensive library of TTS voices and effects, which can give your content a unique sound. Other dedicated AI voice generator apps and websites allow you to create an audio file (like an MP3) that you can then import into your video editor.

The workflow is simple:

1. Write your script and generate the audio in a third-party app.
2. Save the audio file to your phone.
3. Open your video project in CapCut or another editor.
4. Import your video clips and the AI-generated audio file.
5. Sync the audio to the video clips, trim and edit everything together.
6. Export the final video and upload it to TikTok.

This method gives you ultimate creative freedom and can help your content sound different from the millions of other videos using the standard TikTok voices.

Final Thoughts

The TikTok AI voice is more than just a gimmick, it's a powerful tool for storytelling, comedy, and making your content more accessible. By learning to use the built-in Text-to-Speech function and timing your narration effectively, you can elevate your videos and connect with a wider audience without ever needing to say a word.
