Yes, this is another post about AI.
But, we’re not going to go into the whole debate on whether or not the Wyzowl report, 91% of businesses use video as a marketing tool— maintaining an all-time high since 2016.
This video statistic, coupled with the fact that the global AI video generator market size was estimated at $554.9 million in 2023 and is expected to reach $1.96 billion by 2030, is evidence that video will be a huge part of brand marketing campaigns this year and in the years to come.
Whether that’s YouTube videos, explainer videos on your website or landing pages, TikTok videos, Instagram Reel videos, or other social media videos—brands, especially B2B brands, will be creating a lot more video content.
The problem is just that creating videos is not the easiest or fastest thing to do.
Video voiceovers take a lot of work. You have to draft the script, rehearse, do the final take, and edit out the awkward clunky parts.
And when you don’t have the time to do all that? You can use an AI voice generator to do the heavy lifting for you and reap the rewards of using videos in your marketing funnel.
AI text-to-speech platforms help you create natural voiceovers for your explainer videos and product feature updates by just plugging in text on your computer.
I spent a few hours testing out a few voice generator platforms and have curated a list of the best tools for you to use for your video content.
What to look for in an AI voice generator—the winning criteria
So, there are a lot of AI voice generator tools to choose from, like a lot.
Some have pretty basic features, while others have hundreds of voice and accent options, voice stability, and similarity settings that you can toggle until you get the perfect output.
After using a bunch of tools, here’s my list of must-haves I believe all good AI text-to-speech tools should have.
High-quality, realistic voice options: Use a tool that uses high-quality, realistic voices that can accurately convey your message. Some tools use robotic-sounding voices that can be difficult to listen to and may detract from the overall quality of your project
A wide range of customization options: Find a tool that is easy to use and offers a range of customization options. Also, look for a tool with multilingual support. The tool should convey different emotions (e.g., happy, sad, excited) in their speech
Compatibility with other tools: Ensure that the AI voice generator is compatible with your existing tools and platforms, such as content creation software, marketing automation platforms, or voice assistant devices
The complete list of the best AI voice generators
To ensure this was a fair review, I used the free versions of the tools, opted for the default voice, and gave them all this text input:
“This is a fight for the best AI voice generator tool—let’s see who takes home the crown. Is it going to be “you”?”
ElevenLabs
Top features:
Pricing:
Eleven Labs claims to create natural AI voices instantly in any language—perfect for video creators, developers, and businesses. The tool supports 29 languages and all diverse accents.
The dashboard is easy to use. You can select the appropriate accent and enter text in your language of choice. The VoiceLab then allows you to create voices and use them in any language.
You can toggle between “simple” and “advanced” modes. The advanced mode comes with style exaggeration, stability, and similarity settings.
The voice generator produced pretty realistic results, it was impressive. The hundreds of voices and accents to choose from were what set apart Eleven Labs.
Speechify
Top features:
Pricing:
Speechify differentiates itself from its competitors by focusing on the “reading out” part of the text-to-speech platform. The platform also features voices of famous personalities such as Snoop Dogg and Gwyneth Paltrow—it’s fun to have these celebrities read your books out loud to you.
Another unique feature of the platform is that anything you’ve saved to your Speechify library instantly syncs across devices, so you can listen to anything, anywhere, anytime.
Because of the credit card requirement, I just tried the sample text for Speechify. The result was okay-ish, but it did sound a bit mechanical—not as natural as ElevenLabs.
WellSaid
Top features:
Pricing:
WellSaid’s homepage claims the tool uses advanced deep-learning techniques to create lifelike, human-like voices across a range of styles, accents, and languages. And provides a more engaging and immersive listening experience compared to traditional text-to-speech.
WellSaid allows users to create and customize their own exclusive voice avatars, enabling them to build branded, personalized voices for their products and experiences.
While WellSaid does not currently offer a public API, it does provide integrations that allow users to easily incorporate text-to-speech functionality into their applications and digital experiences.
WellSaid empowers voice actors to create and monetize their own custom AI voices, providing them with a comprehensive toolkit to hone their craft and bring their voiceover projects to life.
I chose Tobin A. for my sample text since that seems to be the default option, the result was okay-ish, but it was a little too fast—ElevenLabs’ result sounded better.
One thing to note is that WellSaid doesn’t let you download the file unless you upgrade to a paid plan.
Listnr
Top features:
Pricing:
Listnr’s generative AI Engine lets you create voiceovers with 1000+ different voices in over 142 languages, including a clone of your own voice. You can customize the output by adjusting pitch, pauses, pronunciation, and playback speed.
I used the default voice again, and the output was fine, but it could be better and more natural sounding.
The platform also lets you add emotional inflections like excitement, sadness, or whispering to the generated voices to better match the tone of the content. Another feature that helps make Listnr stand out is that it can convert text into fully animated videos, making it a versatile solution for content creators and marketers.
You can also integrate its voice generation capabilities into its own applications and platforms and export the generated voiceovers in standard audio formats like MP3 and WAV, enabling easy integration into various projects and workflows.
Find the AI voice generator that meets all your needs
AI voice generators give you the unique opportunity to add speed and scalability to your video production process. Though the platforms give you access to lots of other features, the most important one to have is a realistic voice that can sound the most human-like.
Out of the tools I tried for this post, ElevenLabs had the most diverse voice library, the most realistic voices, and cool settings to adjust how the voice-over should sound—plus, you can easily download your sound files. Listnr was a close second.
Videos should be an integral part of your content marketing strategy. To ensure that your videos give you the conversion results you need, remember to add a landing page CTA at the end of your videos or in your descriptions.
