So You Want to Get That 2020 Sonic Voice Right
Ben Schwartz did the voice of Sonic in the 2020 film. That part is simple enough. What actually went into making it sound right is where things get complicated, and honestly, most people don't understand how much work happened behind the scenes after the original character reveal fell apart publicly. When I first worked on a project trying to replicate that voice for a fan film, I assumed it would be straightforward. Just record something fast and energetic. That was my first mistake. The 2020 Sonic voice isn't just speed. It has a specific cadence, a certain breath pattern, and a vocal placement that sits forward in the face rather than back in the chest. Ben Schwartz approaches the character with a particular technique. He keeps his jaw loose and lets a lot of the sound live in his teeth and lips. That's why the voice sounds so snappy and articulate even at high speed. Most people trying to imitate it tense up their jaw, which kills the energy and makes everything sound muffled and strained.
After the initial character design trailer came out in 2019 and the internet basically rejected it, the studio paused production for a year to redesign Sonic entirely. During that time, Schwartz continued recording lines in whatever capacity they needed, but the final product in theaters is a combination of his performances edited and layered with additional takes. The director wanted certain lines to hit differently, so you're actually hearing multiple passes of Schwartz's voice in the final mix, not just one continuous performance. I learned this the hard way. I spent three weeks trying to match a single line from the movie and kept failing because I was trying to perform it as one take. Once I recorded it in three separate passes and layered them the way the original mix does, it suddenly clicked. The secret is in the layering, not in any single performance.
The Technical Breakdown
Let me explain how to approach this if you're trying to reproduce or analyze the voice for your own work. Stand in front of a mirror. Say something in your normal voice. Now say it while keeping your lips almost touching your teeth like you're about to smile broadly. That forward placement is key. Schwartz does this naturally, but it feels weird if you haven't done it before. Your voice will sound thinner, brighter, and more animated. That's exactly what you want. For breath control, don't try to hold your breath between lines. That's a common mistake. Instead, take quick shallow inhales through the nose while the character is moving. It sounds obvious but most voice actors overthink this and end up sounding winded instead of energetic.

Line Delivery Patterns
Watch any scene with Sonic and pause between lines. You'll notice Schwartz rarely speaks in complete, measured sentences. He starts the next thought before finishing the previous one. He trails off mid-sentence and picks back up. This creates that hyperactive, restless quality that defines the character. It's not just about being fast. It's about the irregular rhythm. Here's a practical exercise. Take a script page. Read it at twice your normal speed while walking around the room. Then read it again at normal speed but keep moving. The physical movement changes your breathing and forces that restless energy into your voice. This is probably 70% of what makes the performance work on screen.
Pitch and Inflection
The voice sits somewhere between a tenor and a baritone with a lot of variety between the two. Schwartz drops into lower registers when Sonic is being serious or annoyed, then jumps up quickly for excitement. The transitions between these registers should be sharp, not smooth. A gradual pitch slide sounds weak. A sudden jump sounds alive. I recorded a test clip once where I used smooth pitch transitions and the result sounded like a cartoon character from the nineties. Completely wrong era, completely wrong feel. After switching to abrupt pitch changes, it snapped into the right territory immediately. There's no middle ground here.
Common Pitfalls
The biggest mistake I see people make is focusing entirely on speed. They record themselves going fast and call it done. It never works. Speed without the other elements just sounds like someone talking quickly. The voice from the movie has a specific personality underneath the speed. Another issue is overdoing the chirpy quality. There's a fine line between playful and annoying. Schwartz walks that line consistently, which is why his performance holds up on repeated viewings. Most imitations cross into annoying territory within the first ten seconds because the performer isn't confident in their placement and compensates by going over the top. You also need to consider how the voice interacts with sound effects. In the actual movie, Sonic's voice is mixed alongside Whoosh sounds, footstep impacts, and other audio elements. If you're recording this for your own project, leave space in your mix. Don't compress the voice track so heavily that it can't compete with the sound design. The original mix leaves the voice relatively dynamic so it can sit on top of the chaos without getting lost.

What Actually Worked For Me
My process ended up looking like this. I wrote out a paragraph of dialogue in Sonic's voice. I performed it three times with slightly different energy levels each time. I listened back and selected the best segments from each take rather than using any single full take. I layered those selections together. I added a light high shelf boost around 8kHz to bring out that forward toothy quality. The result was about as close as I got to the original without hiring the actual voice actor. The entire process took me about four hours spread across two days. The first hour was just figuring out the placement. The next two hours were the recording and selection process. The final hour was mixing and refinement. If you're doing this professionally and have experience with vocal performance, you could probably cut that in half. If you're doing it for the first time, budget more like six or eight hours. There's no shortcut around the actual performance work. No plugin or preset will give you this voice. It comes from understanding how Schwartz approached the character and translating that into your own voice. The technical stuff matters, but it's secondary to the performance itself.
