I created this video to walk through how to generate realistic AI voiceovers using OpenAI’s API — and the best part? It costs just 12 cents for 10 minutes of audio.
Whether you’re making YouTube tutorials, product demos, sales pages, or explainer videos, having a high-quality voiceover can level up your content — without needing to record your own voice.
Here’s how I do it with just a script and a few lines of code.
Step 1: Write your script
Start with a well-structured script. Keep it conversational, clear, and formatted with proper punctuation. The more natural your writing, the more human the voice will sound.
In the video, I show one of my actual scripts from a tutorial. I typically write them in Google Docs, then clean up tone and pacing before pasting them into the AI tool.
Step 2: Use OpenAI’s text-to-speech (TTS)
OpenAI’s Whisper and TTS APIs are fast, cheap, and surprisingly realistic — especially the “Nova” and “Shimmer” voices.
If you’re not comfortable with coding, you can use tools like:
-
ElevenLabs (great quality, but more expensive)
-
Play.ht or WellSaid (user-friendly, browser-based)
-
Or run a Python script using OpenAI’s API for full control
I walk through a simple example in the video, generating an audio file from a plain text file using the TTS API.
Step 3: Export and use the voiceover
Once you’ve generated your voice file (usually in MP3 or WAV), you can:
-
Drop it into Final Cut Pro or Screen Studio
-
Sync it with slides, screen recordings, or animations
-
Reuse the same voice across a series for brand consistency
At just $0.012 per minute, you can create hours of professional-sounding narration for just a few dollars.
Bonus tip: Combine this with ChatGPT script writing for a full AI-powered content loop — script, voice, and video all from one workflow.
Are you still recording your voice manually — or are AI voiceovers part of your stack now?
