How to create an AI voiceover in VoiceGen: complete step-by-step voiceover tutorial

A strong voiceover adds emotion and clarity to your videos, but recording your own can be tough, expensive, or time-consuming. That’s why AI tools like Envato VoiceGen are changing the game.

In this tutorial, you’ll learn how to create an AI voiceover and turn your script into a natural-sounding narration using VoiceGen. Powered by advanced text-to-speech technology, VoiceGen creates lifelike audio that feels human and expressive to match your story.

We’ll walk you through the full process: from writing a clear script and choosing the right AI voice to refining tone, pacing, and exporting polished, ready-to-use audio for your videos.

Start here, and discover how fast and easy it is to make professional voiceovers with AI narration tools like VoiceGen.

To make an AI voiceover in VoiceGen:

Even the most advanced AI model can’t fix a poorly written script. Think of your text as the DNA of your voiceover: the structure that defines emotion, rhythm, and flow.

For writing the actual voiceover, you can use AI copywriting tools to help you with idea generation and text editing.

Also, some suggestions to keep in mind:

AI voices are trained on human speech data, but they still rely on punctuation and structure to interpret rhythm. When writing scripts for AI voiceovers:

For example:

Instead of: “Our productivity management solution leverages AI-driven optimization frameworks to enhance efficiency.”

Try using: “This tool helps you save time and get more done, using smart automation powered by AI.”

You can subtly guide the AI to read with feeling by adjusting punctuation and word choice. Commas introduce small pauses; ellipses (…) create suspense or hesitation.

If your tone is inspirational, choose words that suggest energy (“imagine,” “create,” “transform”). For instructional content, lean on calm, clear phrasing (“let’s start by,” “next, you’ll see”).

Separate your script into paragraph-sized sections of 2–4 sentences. Each section should represent one idea or visual moment in your video.

A good rule of thumb: every 80–100 words should fit within 20–30 seconds of narration. This makes timing easier during editing.

When you log in to VoiceGen, you’ll see an interface that allows you to write, paste or upload text, then select your AI voice from a diverse library of options.

VoiceGen provides a variety of voices, and it categorizes them by gender, age range, and purpose. So you can choose which voice fits your video’s tone and intent:

One cool feature that makes generating much easier is that you can get a quick sample of each voice by clicking the top left play button.

For this voiceover tutorial, we’ll be using Larissa and Sarah with settings Female + Young + Social media, since the ad will be a short video for social content.

Think of your chosen voice as an extension of your brand personality. In this case, Sarah is a more enthusiastic voice, and that matches the excitement of a digital nomad’s adventure to work from anywhere.

Pro tip: You can select multiple voices for the same script and preview each generation before downloading the best one.

VoiceGen includes adjustable speed: slow, moderate, or fast.

For this voiceover tutorial we’ll be using this short script as an example:

Once your text and voice are ready, click Generate Audio. Within seconds, VoiceGen produces a full voice track. But the magic lies in iterating and refining until you get the perfect voiceover for your video.

Play your file with a critical ear. Listen for pacing, pronunciation, and emotional flow. If a section feels off, rewrite and generate a new voiceover.

A good practice is to break your script into short paragraphs or sentences. This gives you control to fix small sections without regenerating the entire file.

For dynamic videos, avoid monotone delivery. Increase emphasis slightly for verbs and transition phrases (“Let’s move to the next step”). Conversely, for meditative or explainer videos, keep the pacing slow and balanced.

You can export each paragraph as a separate audio file, especially for tutorials or multi-part videos. This modular approach helps you replace or reorder clips easily during editing.

Your AI narration is ready, but it’s only effective when synchronized smoothly with your visuals.

To create videos, you can use Envato VideoGen along with stock video from Envato and get top-quality footage that shows the destinations mentioned in the voiceover.

Drag your exported audio into a program like Adobe Premiere Pro, DaVinci Resolve, or CapCut. Use the timeline to line up major visual moments (scene changes, text overlays, transitions) with narration cues.

If your voiceover finishes before your clip does, slow it slightly (up to 5%) without affecting pitch. If it lags behind, cut short pauses between phrases.

Pro tip: Use markers to note key transitions or timestamps from your script (e.g., “Intro 0:00–0:15,” “Step 1 0:15–0:45”). This helps maintain flow during complex edits.

Maintain consistent loudness—around –14 LUFS for YouTube and online streaming. If you add background music, reduce it by about 15dB to keep narration dominant but balanced.

Adding captions to social media videos isn’t just for accessibility; it also improves retention and SEO ranking, or you can use your video editor’s auto-caption feature.

Professional-sounding audio doesn’t happen by accident. Even though VoiceGen creates clean output, a few adjustments can elevate your content to studio quality even more.

Every voice has a natural frequency range. For most narrations:

These small tweaks make your voice cut through background music without distortion.

Apply light compression with a 2:1 or 3:1 ratio to even out volume differences. This prevents sudden spikes from sounding jarring and creates a more consistent listening experience.

Some AI voices produce sharp “S” or “T” sounds. Use a de-esser plugin (around 5–7kHz) to soften them. You can also use click removal tools to eliminate digital artifacts.

Normalize your final track to –1dB peak to prevent clipping and distortion. Export your file in 48kHz, 16-bit WAV for video production or 44.1kHz MP3 for web audio.

Dive deeper into sound design basics to learn how frequencies, spatial effects, and mastering techniques enhance your mix.

AI voiceovers are fast, but mistakes can creep in. Here’s how to stay ahead:
