In voiceover work, is it better to specialize in one niche or have a broad portfolio?

This is such a great question!

It's my understanding that 90% of the demos that people listen to (regardless of the niche they're looking for) is your Commercial Demo. So you should definitely have one of those that will show the range of commercial work you can do. 

That said, I wouldn't plan to focus on any one particular niche because you want to be able to go where the work is and you might find out that people think you have a really great voice for video games or voicemail systems or training videos. I have personally done a lot of YouTube videos that I didn't think I would be good for, all because I was willing to do something that made me feel a little uncomfortable. But those jobs have all come from my Commercial Demo. So make sure you have one of those. 

I think when creating a profile, there can be advantages to having both a general gig and a few niche gigs that highlight what your specialties are. For example, I've got a background in both broadcasting and health care. So one of my gigs highlights medical voice over. I also discovered I'm pretty good a ASMR. So I have another gig for that style of vo. Those are in addition to my general gig.  

As someone who’s navigated different aspects of voiceover work—from radio and audiobooks to character voices—I’d say it’s best to strike a balance between specialization and versatility. Specializing in one niche, like commercial voiceovers or audiobooks, allows you to master that craft and build a strong reputation in that field. It can also lead to consistent work because clients know you’re an expert in that particular area.

On the other hand, having a broad portfolio opens up more opportunities and showcases your adaptability, which is invaluable in this industry. For instance, my experience ranges from narrating gripping thrillers like Operation Odessa to emotionally charged factual diaries, each requiring a distinct approach. That variety not only keeps the work exciting but also ensures I’m ready to take on diverse challenges.

Ultimately, the approach depends on your goals and interests. If you enjoy exploring different styles, a broad portfolio can serve you well. But if there's a niche you’re passionate about, specializing might be your ticket to standing out.
