Ever been watching a rerun of American Dad at 2 a.m. and suddenly realized that the insane CIA director sounds exactly like a Shakespearean legend? Or maybe you're humming along to one of Steve’s R&B ballads and wondering if that kid actually has a record deal? You’re not alone.
The show has been on the air for over twenty years now, and while the faces of Stan, Roger, and Francine haven’t aged a day, the people behind them have some of the most fascinating careers in Hollywood. Honestly, the cast is a bizarre mix of A-list movie stars, legendary voice actors, and even a guy who is basically playing himself.
If you've ever wondered who are the voices on American Dad, here is the actual breakdown of the talent bringing Langley Falls to life in 2026.
The Man with a Thousand Voices (and One Alien)
It’s no secret that Seth MacFarlane is the engine behind the show, but his workload on American Dad is actually pretty staggering. He doesn't just do one voice; he defines the show’s entire dynamic by playing the two biggest personalities.
First, there’s Stan Smith. MacFarlane uses a deep, authoritative baritone for Stan, modeled after old-school 1950s radio announcers. It’s that "all-American" voice that makes Stan’s absolute insanity even funnier.
Then you have Roger the Alien. If you think Roger sounds a bit like Paul Lynde (the flamboyant comedian from Hollywood Squares), you’re right on the money. Seth has openly admitted that Lynde was the inspiration. It takes a specific kind of vocal gymnastics to flip between Stan’s macho grunts and Roger’s high-pitched, wine-soaked theatricality. Seth also voices Greg Corbin, the local news anchor and Stan’s neighbor.

The Secret Weapon: Scott Grimes as Steve Smith
Most people know Scott Grimes from his live-action work on ER or The Orville, but to animation fans, he is the undisputed king of the "puberty crack."
Steve Smith is arguably the most vocally demanding character on the show. Why? Because the kid sings. A lot. And he’s actually good.
Scott Grimes is a legitimate musician in real life—he’s released several albums and even had a hit single called "Sunset Blvd" that spent weeks on the Billboard charts back in 2005. When you hear Steve hitting those high notes in "Daddy's Gone" or "Is She Cheese?", that’s not auto-tune. That’s pure Scott Grimes. It’s kind of wild to think that the dorkiest kid in Langley Falls has the pipes of a soul singer.
Wendy Schaal and the Evolution of Francine
Wendy Schaal provides the voice for Francine Smith. In the early seasons, Francine was written more like a typical "sitcom mom," but as the show evolved, Wendy’s performance helped turn her into one of the most unpredictable characters on TV.
Whether she’s doing her "high-on-cooking-fumes" voice or her "tough-as-nails-street-fighter" persona, Schaal brings a weirdly grounded energy to the chaos. Fun fact: Schaal comes from a massive acting pedigree—her father was Richard Schaal, a staple of 1970s television. She’s been in the industry for decades, appearing in cult classics like The 'Burbs, but Francine is definitely her most iconic role at this point.

Is Jeff Fischer Actually Jeff Fischer?
This is one of those "truth is stranger than fiction" situations. Jeff Fischer, the stoner son-in-law who married Hayley, is voiced by... a guy named Jeff Fischer.
The character was literally created for him. Jeff is a long-time friend of Seth MacFarlane, and they decided to just put him in the show as a fictionalized version of himself. He’s a professional voice actor outside of the show (you’ve probably heard him in various video games like Final Fantasy or Tony Hawk’s Underground), but on American Dad, he’s basically just being Jeff.
It’s probably the easiest job in Hollywood, right? Except for the episodes where he gets sucked into a space vortex for three seasons.
The Rest of the Smith House
- Rachael MacFarlane (Hayley Smith): Seth’s younger sister isn't just there because of her last name. She’s a powerhouse voice actress who has worked on everything from The Grim Adventures of Billy & Mandy to Family Guy. She gives Hayley that perfect blend of "annoyed activist" and "closet party girl."
- Dee Bradley Baker (Klaus): If there is a creature in a movie or show making a weird noise, it’s probably Dee Bradley Baker. He voices Perry the Platypus and every Clone Trooper in Star Wars. For Klaus, he famously gave the character a German accent after the producers originally envisioned him as French. Dee thought German would be funnier for a man trapped in a fish body, and he was 100% right.
The Heavy Hitters in the Supporting Cast
This is where the show gets really "prestige."
The CIA scenes wouldn't be the same without Sir Patrick Stewart voicing Avery Bullock. It is objectively hilarious to hear a Knight of the British Empire say some of the most depraved, drug-fueled lines ever written for television. Stewart has said in interviews that he absolutely loves the role because it allows him to do things he’d never be allowed to do on a Shakespearean stage.

Then there’s Kevin Michael Richardson as Principal Lewis. Richardson has one of the deepest, most recognizable voices in the business (he’s the new voice of Dr. Hibbert on The Simpsons). His portrayal of the unhinged, "rum-fueled" high school principal is a fan favorite.
We also can't forget Richard Kind as the lovable, tragic neighbor Tuttle. Richard Kind's natural voice is so distinct and neurotic that he doesn't even have to change it much to make Tuttle the most pathetic man in Virginia.
Why the Voices Still Work in 2026
The reason American Dad has outlasted so many other animated shows is the chemistry. Even though these actors often record their lines separately, the comedic timing is surgical. They’ve been playing these characters for over 350 episodes. At this point, they know exactly how Stan would react to a Roger prank or how Steve would scream in terror.
If you’re looking to dive deeper into the world of Langley Falls, your best bet is to check out the "Behind the Scenes" features on the Season DVD sets (if you still have a player!) or follow the cast on social media. Scott Grimes often posts clips of his recording sessions, which really shows you how much effort goes into Steve's shrieks.
To get the most out of your next rewatch, try to spot the "guest" voices. The show frequently brings in legends like Paget Brewster or even Snoop Dogg for one-off characters. Pay close attention to the credits next time—you’ll be surprised at how many Hollywood stars are hiding in the background of a CIA briefing.
Keep an eye out for upcoming guest star announcements for the new season, as the show's producers have been teasing some major cameos from the world of 2020s pop culture.
Actionable Insight: The next time you watch an episode, listen specifically for the musical numbers. Now that you know Scott Grimes is a professional singer, you'll notice the incredible technical skill he uses to keep Steve's voice "in character" while hitting complex melodies. It’s a masterclass in voice acting.
