Voice-over & voice acting
Voice-over and voice acting for commercials, e-learning, animations, explainer videos and documentaries. Recorded in my own studio and delivered fast.
Demos and bookings at destemkunstenaar.nlFirst the core. Then the mix.
I'm Jöran Aerns, a multipotentialite: I do voice-overs, make music and podcasts, rent out podcast kits, build websites and help small businesses with AI. Create From Core is the core I do all of that from. Whichever channel you open up, I start at the core of your message.
As Sjefke I'm a Dutch-language artist with the carnival song “Wa hedde geprompt”. Together with the zjeepeetees I bring the carnival spirit to your venue, party tent or pub.

2011 – 2026
15 years of Create From Core.
Since 2011 I've been making things from Create From Core: websites, songs, voice-overs and podcasts. For fifteen years I've had the chance to play a part in other people's stories.
Always from my core quality: my creativity!
Thank you to everyone who has played along over the past fifteen years: clients, bandmates, colleagues and listeners. On to the next record.

Music
I write and sing. With Zabatista I made the rock album 'It All Starts Here', during the pandemic I released the single 'Coronapup', and as my carnival alter ego Sjefke, of Sjefke en de zjeepeetees, I sing 'Wa hedde geprompt'.
Listen to Wa hedde gepromptPodcast production & podcast kit hire
I make and edit podcasts for you: recording, editing, voicing the intro and outro, and finishing it into an episode that's ready to publish. Rather record it yourself? Then hire a complete kit for four people, with a Rødecaster Pro, four Røde PodMics and headphones. By the day, weekend or week.
Book at podcastsethuren.nlWebsites & AI for small businesses

As a narrator and host I've appeared at Opera Rocks, Scrooge and Band meets Choir, and I'd love to do it again. Looking for someone to host your evening? Let me know.
