6 Tips for Creating the Best AI Voiceovers: Advice from WellSaid and Vyond

The evolution of AI voiceover generators 

The first AI voice generators to emerge were novel and exciting, but their AI voices sounded robotic and awkward. They were clearly AI-generated and not serious options for replacing human voices in video and audio content. 

But since then, AI voice generator technology has drastically improved. Many of today’s AI voices are modeled after real voice actors (via ethical partnerships), so they’re smooth and natural-sounding — and often impossible to tell apart from human voices. 

AI voiceover generators’ evolution holds huge benefits for businesses, educators, and content creators. Why? 

Voices play a key role in video content, whether it’s for training, marketing, communications, or sales. And the quality and authenticity of those voices make all the difference when it comes to creating content that resonates with audiences and changes behavior. And there’s more.

Benefits of using AI voiceover generators

Working with AI voiceover generators also brings perks like cost savings (no studio or re-recording fees), time savings (no juggling schedules and waiting for edits), flexibility (translate into multiple languages; make unlimited edits), and scalability (bring consistency across projects and entire companies). 

It’s why Vyond offers users a multitude of AI voice options. And the ultra high-quality voices from WellSaid, integrated seamlessly into Vyond’s Enterprise and Agency subscriptions, are one of the features most appreciated by Vyond customers.

Common challenges with AI voiceover generators

There are three challenges users bump up against with AI voice generators. Sometimes the first take has a flatter tone and delivery than they’d like. In some cases, the AI voices might use odd or incorrect pronunciation for certain words. Or the speech speed is slower or faster than they’d prefer. 

The good news is, all of these challenges are addressable. And while AI generator tools are intuitive, understanding some of their quirks can help you get the most natural-sounding results from the outset.

Here are six expert tips for getting natural-sounding AI voice results, from me and WellSaid’s Nate Grieb. (To hear these straight from the source, hop to 20:23 in the webinar replay.)

6 expert tips for the best AI voiceover results

Tip 1: Choose the best AI voice for the job

Different projects call for different tones and styles. Depending on your project, you might be drawn to a voice that sounds more conversational, instructional, promotional, or narrative. Just like a voice actor can flex here, many voice options can be adjusted so they lean more into a certain style.

Some users prefer to browse voice styles first and choose from there. Others like to “shop” for voices by testing them out on sample sections of their script. Remember, you’ve got unlimited retakes, so don’t be afraid to experiment! 

When in doubt, Nate says you can’t go wrong with Ava, Wade, or Alana from WellSaid’s collection.

Tip 2: Structure your script for clarity

Shorter sentences yield smoother narration than long, complex sentences, and they’re helpful for audience comprehension, too. Shorter sentences also make for easier editing!

Use punctuation strategically to create meaningful silence and emphasis: commas for slight pauses, periods for longer breaks. Ellipses and manual line breaks can improve pacing.

Tip 3: Fine-tune pronunciation for accuracy

AI voices are trained on broad vocabularies, but they may misinterpret specialized words or proper names. There are a few ways to work around it.

You can use quotation marks for emphasis (e.g., “pro”duce vs. pro”duce”). You can also spell out words phonetically to get the correct pronunciation — so Saskatchewan becomes “sask-ACH-oo-when” and San Mateo becomes San Ma“tayo”.

Tip 4: Mind your acronyms and numbers

Acronyms and numbers can be especially tricky for AI voices to decode, so pay special attention to these in your script. 

With acronyms, it can be helpful to spell them out phonetically — for example, you might spell out the common learning and development acronym “L&D” as “Ellen Dee.” You can also try using dashes, periods, or spaces for letter-by-letter pronunciation, like for “T-B-D” and “A.S.A.P.”

With numbers, context matters a lot, so format them clearly for AI interpretation. If by “2025” you mean the year, try spelling it out how you’d like it pronounced: “two thousand twenty-five.”

Tip 5: Adjust vocal inflections to sound more human

Human speech has nuances that make delivery more dynamic — like how fast or slow we talk, how high or low, how often and long we pause. 

Play around with speed, pitch, and pauses (commas for slight pauses, periods or line breaks for longer breaks) in your AI voiceovers to mimic natural speech patterns.

Before-and-after example: How small tweaks can dramatically improve AI narration

It’s tempting to dump your entire script into one window to generate text to speech in one go. But breaking your AI narration into smaller sections makes it easier to hone in on issues and adjust the content as needed — now or in the future. This principle is especially important for complex scripts or long-form content.

Recap: Getting the best AI for voiceovers 

These six tips will help you get better results with AI voiceovers at the outset and address challenges you encounter. Keep testing and refining for best results: The beauty of working with AI voices is your voice actors never get tired or sick, and retakes are unlimited!
