You know that specific, frantic scream? The one that sounds like a teenage girl is about to vibrate out of existence because her brothers just built a fully operational roller coaster in the backyard?
That is the sound of Ashley Tisdale.
Most people hear the voice of Candace on Phineas and Ferb and immediately picture Sharpay Evans in a pink locker. It makes sense. In the mid-2000s, Tisdale was the undisputed queen of the Disney Channel. But if you actually sit down and listen to Candace Flynn—the way she shrieks "MOM!" or the way her voice cracks when she’s trying to impress Jeremy—it’s clear this wasn't just another paycheck. It was a vocal marathon that, quite frankly, sounds exhausting to record.
The Woman Behind the "Bust"
Ashley Tisdale has been the voice of Candace on Phineas and Ferb since the pilot aired back in 2007. While she was filming The Suite Life of Zack & Cody and dancing through High School Musical, she was spending her "off" hours in a recording booth, screaming her lungs out.
Honestly, it’s kind of wild how much longevity this role has. Most Disney stars do their four seasons and vanish into the "Where Are They Now?" void. Not Tisdale. Even after the original series ended in 2015, she came back for the 2020 movie Candace Against the Universe. And now, with the 2025/2026 revival seasons in full swing, she’s still the one behind the mic.
She's mentioned in interviews that playing Candace is "like a workout." She isn't kidding. If you’ve ever tried to mimic that high-pitched, neurotic energy for more than thirty seconds, you know it’s a one-way ticket to a sore throat.

Why Candace sounds so... intense
There’s a reason the voice of Candace on Phineas and Ferb feels so visceral. Tisdale doesn't just read the lines; she goes full "manic mode."
The creators, Dan Povenmire and Jeff "Swampy" Marsh, have often talked about how Ashley would show up to sessions and just let loose. She’s gone on record saying she can only record for about two hours at a time. After that? Her voice is basically shot. Think about that: two hours of yelling about a giant floating baby head or a backyard beach. That’s dedication.
What most people get wrong about the casting
There’s a common misconception that Candace was modeled after Ashley Tisdale herself. Not exactly. The character was actually inspired by Jennifer Grey’s character, Jeanie Bueller, from Ferris Bueller’s Day Off. You know, the sister who is obsessed with catching her brother?
When Tisdale auditioned, she brought a specific kind of "likable franticness" that the producers hadn't quite found yet. They didn't want a villain. They wanted a sister who was just... right on the edge of a breakdown.
A quick look at the "Other" Candaces
Believe it or not, there have been a couple of other people involved in the Candace-verse:

- Shelby Young: She’s stepped in for things like Disney Broken Karaoke. She does a killer impression, but she isn't the "main" voice.
- The Singing Voice: Unlike some animated characters where a professional singer takes over for the musical numbers, that is almost always Ashley Tisdale singing. From "S.I.M.P. (Squirrels in My Pants)" to "Busted," those are her real pipes.
The 2025/2026 Revival: Is she still the same?
If you’ve watched the newest episodes, you might notice something. Candace sounds a little... different? Not bad, just... older?
It’s been nearly twenty years since the show started. Ashley Tisdale is a mom now. She’s a business owner. She’s grown up. In the recent revival, there’s actually an episode where Candace finally goes to therapy (long overdue, let's be real). Tisdale has talked about how she had to find that "craziness" again.
She told EW that she was actually nervous about whether she could still hit those high-energy notes. But as soon as she stepped back into the booth with Dan and Swampy, the "MOM!" just came right back out. It’s muscle memory at this point.
Why this performance actually matters
We talk a lot about "prestige" acting, but voice acting like this is incredibly difficult. You’re conveying an entire personality through nothing but pitch and timing.
Candace could have been an incredibly annoying character. A sister who just wants to ruin her brothers' fun? That’s a buzzkill. But because of Tisdale’s performance, we actually feel for her. We see the vulnerability. When she’s talking to her best friend Stacy, or getting tongue-tied around Jeremy, she feels like a real teenager who is just overwhelmed by the absurdity of her life.

How to spot a true Tisdale performance
If you're wondering if you’re hearing the real voice of Candace on Phineas and Ferb in other media, look for these "Tisdale-isms":
- The Vocal Crack: She has a very specific way of letting her voice break when Candace is frustrated.
- The Rapid-Fire Delivery: Candace talks fast. Tisdale’s background in musical theater helps her hit those beats without tripping over the words.
- The "Mom!" Scream: Accept no imitations. There is a specific grit to the way she yells it that belongs to Ashley alone.
Basically, Ashley Tisdale didn't just voice a character; she created a blueprint for the "frenetic sister" archetype in modern animation. Without her, the show’s dynamic—that constant tug-of-war between the boys' imagination and Candace’s reality—would probably have fallen flat.
Next time you're watching a marathon, pay attention to the musical numbers. Try to see if you can hear the difference between the 2007 episodes and the 2026 revival. It's a masterclass in how an actor can evolve while keeping a character's soul exactly the same.
