If you haven’t seen it yet, I made a fictitious React Native Radio podcast episode for Infinite Red in record time using a new AI tool.

While React Native Radio is always known for being fun and funny, a lot of work goes into every episode… except the one above.

How long did it take?

I had the whole thing done in about 30 minutes from idea to solution. I guess I spent more time on this blog post than I did doing the thing.

A year ago, I did something similar for a joke on Twitter, and it took longer and was a lot harder. It also didn’t let me pick out who to use as a voice!

I’m amazed at how easy it was today.

Why do this?

Besides being a fun example, this tooling could be used to help you handle long blog articles in a friendly voice, filling in gaps in podcasts, and even creating an amazing presentation at the last moment, without haveing the talent run to a recording booth!

This is a new AI future, and it’s easy.

How did I do this?

First, I needed to get over a minute of audio from our hosts. That’s not hard, because they upload their individual audio files after each recording of https://reactnativeradio.com/

Jumping into the thread, I grabbed 40ish minutes of their audio.

The audio is in the lossless .flac format, so I had to quickly convert it to mp3. I then broke it into chunks of about 10MB mp3s.

Next, there are a lot of open source repos to make text to audio, but I’ve been significantly impressed with the work of the Eleven Labs product which has a free tier: https://beta.elevenlabs.io/

From their service, I used their “Voice Cloning”

Here I created new “Instant Voice” for my podcast guests, and uploaded their samples for training.

After the models were ready, it was just a matter of writing an award winning script and then generating each person’s parts.

At first, the voices were pretty flat, but once I opened the voice settings, I brought the stability down to 25% and bumped the clarity/similarity up to near 90%.

et voila! It was extremely accurate with some voices, but only slightly accurate with others.

Once I had all the generated dialogue set, I just brought it into an editor to cut and smash it back together in conversational format.

The result is a podcast that never really happened!
