Boost Your TikTok Content with AI Voice Generators

Almost every TikTok user has come across a video narrated by an AI voice or a TikTok voice-changing filter. The TikTok text-to-speech character ''Jessie'' is one of the most popular AI voices on the platform. However, third-party voice generators are also available to speak in different accents and tones.

These voices can make your content funnier or help you convey a message in a unique way. However, you need to perfect the balance between the AI part (the voice) and the human element (the content) to make your videos engaging. Without it, the outputs can come off as unnatural and robotic.

Our TikTok Marketing Report reveals that 51.9% of users are already playing around with AI-generated avatars. Add AI voices to the mix, and you could be running the risk of overusing AI and losing the human touch that TikTok users enjoy. In this guide, we explain how to use AI voice generators or TikTok's built-in text-to-speech function without this risk.

Why AI Voices on TikTok Are So Popular

TikTok's text-to-speech voices have become somewhat of an identity for the platform. Users who don't want to use their own voice tend to use this feature to narrate their videos.

The most probable reason that comes to mind for TikTok AI voices being so popular is that they let creators use a range of tones and styles instead of just sticking to their natural voice. They add a personal touch without revealing the creator's real voice. Plus, AI voices are fun and unique, which aligns with the overall vibe of TikTok.

In fact, there are some TikTok channels that solely use AI voices for all their videos. Psychobrainy is one such account that uses AI voices to narrate historical facts or interesting stories.

However, creative freedom isn't the only reason. A Reddit post discussing the reason behind the popularity of AI voices revealed quite a few interesting theories.

One of them is that AI voices are easier to understand for non-native speakers and those with hearing difficulties. As a result, the videos become more inclusive and appealing to a wider audience.

One user said that it's comparatively easier to write a language than to speak it for non-native speakers. Similarly, some of these speakers may not be too comfortable speaking in their native accents, so they switch to AI voices as a workaround.

Also, not everyone has resources or access to expensive equipment or a paid tool for voiceovers. So, they just use the built-in feature on TikTok.

It has also been suggested that TikTok's algorithm boosts videos that use the AI voice feature. Whether or not it's true, creators may believe that using it increases their chances of getting featured on the "For You" page.

Understanding AI TikTok Voice Generators

Just to be clear, there's a difference between a voice generator software and TikTok's built-in text-to-speech feature. The latter is present within the app, while the former is a stand-alone program that you can download and use on your device.

Voice generators have advanced features such as tone and pitch control that you can use to make the audio sound less robotic and more natural. These tools also have multiple voice options and language choices.

But for most TikTok creators, the built-in option is more than enough. It's quick to use and gets the job done. You simply have to type the text in the designated box and choose a voice (either male or female), and the app will generate audio for you to use in your video.

On the contrary, AI voices from third-party tools require you to edit the videos outside the TikTok app. Some of these tools also let you clone your voice. You just have to add a sample of your voice, and the AI will generate audio that sounds like you.

Common Issues When Using AI TikTok Voice Generators

When using AI TikTok voice generators, you're likely to come across the following issues. We explain how to resolve them, too.

1. Location Restrictions

TikTok's built-in American sounds are not available in all regions. So, if you're outside the US, you may not be able to use this feature.

The quickest solution is to use a virtual private network (VPN) to change your IP location. You can then access the US sounds and use them in your videos. There are plenty of free and paid VPN options available, so you should have no trouble finding one that works for you.

Another method that might work is removing your SIM card and using Wi-Fi to connect to the internet. Since TikTok won't recognize your location without a SIM card, you may be able to access the American sounds.

2. Audio Quality and Authenticity

With TikTok's built-in sounds, you run the risk of robotic and artificial-sounding voices, which may not suit your content or brand. That's why you'd see most known brands using this feature sparingly.

For example, in this video, The Positive Piece, a puzzle brand, only uses the text-to-speech American female voice to introduce the video. The rest of the video has music.

@positivepiecepuzzles Out with the old, in with the new #jigsawpuzzles #puzzletok #puzzles #midnfulness #mindfulnesstips #giftideas #mentalhealth #art #selfcare ♬ original sound - tomthird

A workaround is to use third-party AI voice generators. These tools have a lot of voice options, so you're sure to find something that goes with your brand. Plus, you can change the pitch, speed, accent, and other parameters for a more personalized sound.

3. Technical Hurdles

It's quite simple to use the TikTok text-to-speech feature. You just have to sync the words with the video, and that's it.

However, if you're mouthing the words in the video, you'll have more trouble. You have to be sure that the words match your lip movements, which can be difficult and time-consuming. The same issue persists in third-party voice generators, too.

If the voice is too fast or too slow, you'll have to reshoot the video and try again. You can solve this issue by adjusting the playback speed. Slightly speed up or slow down either the video or the AI voiceover to create a seamless match without affecting quality too much. Most editors have fine-tune speed controls.

4. Over-Reliance on AI

If you're using an AI voice, an AI avatar, and an AI filter, the video becomes too automated and loses its human touch. Given that TikTok is all about authentic, relatable content, you have to strike a balance between using AI features for convenience and maintaining the human element in your content.

The Positive Piece above is a good example. They've used the text-to-speech feature but also a TikTok sound and a human in the video. The video is now well-rounded and feels like a friend showing you something cool.

5. Ethical & Compliance Concerns

The thing with AI is that nothing it creates is actually ''new''. Everything it creates is a synthesis of existing data.

When you use an AI voiceover, either from TikTok or a third-party generator, it raises ethical and compliance questions. If the voice is someone else's, do you have the right to use it? If not, are you infringing on someone's intellectual property rights?

An issue like this arose when Justine Camera, a TikTok creator, used an AI tool to add Morgan Freeman's voice to her video. She jumped on a TikTok trend in which people make their family or friends do voiceovers for their vlogs.

In her vlog, she used Freeman's voice for voiceover, claiming that she was his nepo niece. Later, when the video went viral on X and Freeman also responded to it with concern, the creator said that she thought it was an ''obvious joke.''

To be safe, don't use the AI voices of popular celebrities or public figures without their permission. Instead, opt for generic AI voices or clone your own voice for originality.

6. Shadowban or Spam Risks

Let's debunk the myth that using AI-generated voiceovers will get you shadowbanned or labeled as spam. The truth is TikTok does not have clear guidelines or rules on the use of AI voice.

You can use it as long as you have the right to do so and do not violate any intellectual property rights. In a Reddit comment, someone said that they generate AI videos for TikTok and have reached 500k views in under a month. So, it's certainly possible to grow your following and reach with AI-generated content, including voiceovers. 

AI Voice Generators for TikTok: Easy Setup Tips

Whether you're using TikTok's text-to-speech feature or a third-party tool, here's how to set up AI voiceovers for your TikTok videos.

Draft Your Script

Even if your video is 20 seconds long, it should have a script. It doesn't have to be something super-elaborate. As long as it flows well and is interesting, you're good to go.

For example, in this video, The Sill has created a sentence-long draft for their 9-second video. The rest is conveyed through the girl in the video herself.

@thesill Relatable am I right? #thesill #plantsmakepeoplehappy #plantlover #payday ♬ Joel Beam-JP - Carlton Banksy

If you're creating a branded video, it's best to keep the draft short and concise. For funny videos, keep comedic timing in mind.

Your brand style also comes into play. For example, if you're a makeup brand, your script may be a tutorial or a tip. In contrast, if you have a meditation app, your script could be a guided meditation exercise.

Choose Your AI Voice Option

Next, decide if you'll use the default text-to-speech feature on TikTok or a third-party AI voice generator. Like The Sill's video, short voiceovers can be done on TikTok without coming off as too robotic.

However, if you're planning to make a longer video, it's better to use an external tool. This way, you have more control over the tone of the voice. Also, you can use different AI voices for different characters or scenes in your video.

Fine-Tune the Audio

As we've covered, you don't want the sound to be robotic or monotonous. Play around with the tool's features to see how much control you have over the voice. Then, adjust the pitch or speed according to your preference.

Make sure the audio levels are balanced and not overpowering other elements of your video, such as music or sound effects. If you're using an accented voice, adjust its speed accordingly so it's still easy to understand.

Import into TikTok or Another Editor

If your video is ready to be posted, import it into TikTok. The best format for voiceover videos is MP4. If you're using a third-party editor, export your video as an MP4 file and then upload it to TikTok.

If you want to add more effects or edits to your video, use a different video editing software. Once you've finalized it, save it as an MP4 file and import it into TikTok for posting.

Preview & Tweak

Before you hit that share button, play your video a few times. Check for any issues with it, such as audio levels or timing.

If you've added text to the video, also check for typos or awkward phrasing, and if there are subtitles in the video, make sure they are synced with the voiceover. 

Maintaining Authenticity & Personal Flair

When you use AI for social media content creation, it comes with the risk of losing personalization and authenticity. However, you can avoid this by interjecting human elements into your videos.

For example, if you're using an AI voice, don't use AI to generate the video's visuals too. Let there be equal parts human creativity and AI assistance in your videos.

In this video created by Sephora, the voiceover is done using TikTok's text-to-speech feature. However, the video shows the products being discussed. Sephora has integrated its brand's offering into the video so that viewers know who is behind the content.

You can also use a mix of real and AI voices. For example, if you're making a point-of-view (POV) video, the AI voice can introduce the scenario while you take on the character's role. Keep experimenting with different ways and notice which blend the audience interacts best with.

For example, in this video, Nike has used an AI voice to set the scene for what the video will be about. Then, the people in the video speak for the rest of the duration.

Similarly, you can feature yourself or your product within a video with an AI voice. For example, Linda Tong Planners has used an AI voice to introduce her product. However, she shows her planner and its features throughout the video, maintaining authenticity and human connection.

Tips to Boost Engagement with AI Voiceovers

Sometimes, AI voiceovers can fall flat since they fail to imitate the natural fluctuations, urgency, intriguing tone, or humor that a human voice may use to hook viewers right off the bat. You can avoid this by using storytelling right.

For example, start right away with something that will grab the viewer's attention, and then let the AI voice take it from there. In this video, At Home, a home decor store starts the video with ''Introducing the Oh Joy! collection.'' It instantly makes you want to stay because now you want to see what's so special about this collection. This technique of kicking off with an irresistible hook is a proven way to pique curiosity and keep viewers glued to your video.

Shop the NEW Oh Joy! for At Home collection now, in-store, and online via the link in bio! @ohjoy #OhJoyxAtHome #AtHomeStores ♬ original sound - AtHomeStores

You don't only want people to watch your videos but also convert. For that, your video needs a call-to-action (CTA) that encourages action. Use wording that gives a sense of urgency, like ''don't wait'' or ''limited-time offer.'' Combine the voice with an equally compelling video, and you'll have a banger.

In this video made as a response to a comment, Flaire & Co. uses phrasing like ''we need to raise our standards.'' The ''need'' brings urgency to their message. In the video, they show their jewelry being passed under a faucet and in the tub without losing its shine, showing the audience that they are the ''standard.''

@flaire.co Reply to @maddy_rodabough Good quality jewelry doesn’t have to be expensive!! #affordablejewelry #jewelryhaul #goldjewelry ♬ original sound - Flaire & Co.

CTA-based phrasing like this proves to be very impactful. With just a 10-second video, the company managed to get nearly 57k likes. 

What's Next for AI Voice Tech on TikTok

The rise of conversational AI goes hand in hand with AI voice generation for everything from content generation to marketing and advertising. Going forward, you can expect to see more features in text-to-speech and speech-to-speech tools.

Just recently, ElevenLabs, an AI voice startup, raised $250 million at a $3 billion valuation. As more money is being poured into this industry, we can expect to see even more innovation and advancements in AI voice technology on platforms like TikTok.

Customization in voice generation will likely become more prevalent. As tools like ElevenLabs become more advanced, AI voices will start sounding more and more human-like, making it harder to distinguish between a real voice and a generated one. In fact, PlayAI, another AI voice startup, has raised $21 million to create AI-powered voice applications that closely mimic human speech.

Even within TikTok, new AI voice features are being introduced. The platform has released a new feature that lets users create their own AI voice for text-to-speech. Users only have to record a few lines with their voice to generate an identical AI voice. They can then use this voice privately.

While these features are impressive, to say the least, they also raise concerns about the ethical implications of AI voice technology. Morgan Freeman's example above is a testament to this. Other concerns include voice cloning and the potential for AI voices to be used in fake news or scam calls.

We'll need more regulations to prevent the misuse or manipulation of AI voices for unethical purposes. What you can do on your own is to use AI voice technology responsibly and avoid using voice clones or public figures since they're usually unconsented. 

Your Next Viral TikTok Might Just Need an AI Voice

We all love TikTok sounds; they're funny and relatable. But not every TikTok video can use sounds, especially if you're a business. You have to follow a script, and for that, you need a voice that can bring your message to life.

However, hiring a voice actor can be costly and time-consuming. Sometimes, you may want to spice things up a bit and try something new. TikTok's text-to-speech voices and external AI voice generators allow you to do this.

As we've explained in the guide above, you can definitely use these voices without the monotone, robotic sound. Just make sure the video doesn't completely lack human involvement, and you'll be good to go.
