Voice Changer for Splatoon 3 Splatfest: Squid Up Your Squad
A real-time splatoon 3 voice changer turns your Discord call into the Splatsville backstage — Pearl hyping the crowd, Marina on smooth control, Shiver dropping eerie tones, Big Man with that gentle “Ay” bass, or your whole squad locked in full Inkling gibberish for three rounds of Splatfest chaos. This guide covers exactly how to set it up, which effects nail each character, and how to coordinate your team when Nintendo’s own voice system is, well, still not great.
TL;DR
- Splatoon 3 does not have native in-game voice chat — run Discord on PC alongside your Switch for squad comms.
- A real-time voice changer on Windows creates a virtual microphone that Discord sees as a normal input.
- Inkling voices need +4 to +5 semitones, formant shift up, and mild chorus. Octoling gets a slightly smokier variant.
- Pearl = bright + chaotic (+5–6 semi), Marina = smooth + melodic (+3–4 semi), Shiver = cool + ethereal (chorus + slight lower pitch), Big Man = warm bass (-3–4 semi with low-mid boost).
- The whole setup takes about ten minutes and works without any kernel driver or anti-cheat conflicts.

Why Splatoon 3 and Voice Changers Are a Natural Pair
Splatoon is built around personality. The entire visual identity of the game — the fashion, the music, the Inkopolis news anchors, the Splatsville trio — is dripping with character voice. But Nintendo’s approach to voice chat in online multiplayer has always been minimal: Splatoon 3 uses the Nintendo Switch Online app on your phone for Salmon Run and certain private lobbies, and there is no native in-game party voice for standard Anarchy Battles or Splatfest teams.
This creates a natural opening. Competitive and casual Splatoon squads almost universally move to Discord for voice coordination. And Discord on a Windows PC is exactly where a voice changer like VoxBooster slots in — it registers a virtual microphone, your Discord call picks it up, and everyone in your squad hears the transformed voice.
The result during Splatfest is genuinely fun. Three teams, three different vibes, and 72 hours of chaos where showing up in character adds to the whole event atmosphere. Whether you are Team Pearl, Team Marina, Team Shiver, or rooting for Big Man’s quiet revolution, having the right voice effect running makes the hype feel real.
How Switch Voice Chat Actually Works (and Why PC Is Better)
Before getting into effect settings, it is worth being clear on the audio path — because this question comes up every time someone new tries to set this up.
Nintendo Switch Online app (mobile): This is Nintendo’s official voice solution. It works for the game modes that support it, but the app is separate from the game, requires you to pick up your phone, and offers zero customization. You cannot route a voice changer into the Nintendo Switch Online app easily because it runs on your phone, not your PC.
Discord on PC: This is what the competitive Splatoon community uses. You join a Discord voice channel on your Windows PC while playing on Switch. The PC handles all voice communication; the Switch handles the game. This separation is actually ideal for voice changers — the PC audio path is fully under your control.
The setup chain:
Real mic → VoxBooster on Windows PC → Virtual Mic output → Discord input → Squad hears the effectYour Switch gameplay, network connection, and Nintendo account are untouched. The voice changer only exists in the Discord audio path on your PC.

Installing and Configuring VoxBooster for Splatfest
Step 1 — Download and Install
Download VoxBooster from voxbooster.com/download. The installer runs on Windows 10 and 11, requires no kernel driver, and adds no system services that need administrator persistence. Installation takes about 90 seconds.
Step 2 — Set Your Input Device
Open VoxBooster. In the input selector at the top, choose your real physical microphone — the USB headset, headphone combo, or condenser mic you normally speak into. This is the source audio.
Step 3 — Choose or Build a Preset
VoxBooster ships with a preset library. For Splatoon characters, the starting points are:
- Inkling Kid — look under character voices; high-pitch, squiddy, fast formants
- Anime High Pitch — adjustable base for Shiver’s ethereal range
- Deep Warm — base for Big Man; adjust from here
You can also build custom presets from scratch using the pitch, formant, and EQ sliders. Detailed settings for each character are in the sections below.
Step 4 — Select VoxBooster Virtual Microphone in Discord
Open Discord > User Settings > Voice & Video. In the Input Device dropdown, select VoxBooster Virtual Microphone. Do a quick voice test — click “Let’s Check” and speak. Everyone in your next call hears the effect.
Step 5 — Bind Hotkeys for Splatfest Switching
This is the move for Splatfest specifically. You can bind different presets to hotkeys in VoxBooster’s hotkey manager:
F1— Inkling neutral (default squad chat)F2— Pearl hype mode (loud, bright, peak chaos)F3— Big Man “Ay” mode (the ultimate punctuation)
Switch between them mid-call without leaving the game or touching the app. This makes those Splatfest reaction moments hit much harder.
Inkling Voice: The Core Splatoon Sound
The Inkling voice is what most people picture when they think “Splatoon voice changer.” It is a high-pitched, non-linguistic, somewhat wet-sounding vocal style with quick consonants and rounded vowels. Inklings speak a phonetic gibberish that sounds like English or Japanese if you speed it up and pitch it up, but never resolves into real words.
What Defines Inkling Voice Acoustically
- Fundamental pitch roughly +4 to +5 semitones above a typical adult voice
- Formants shifted upward — the vocal tract sounds smaller, like a child or a small-bodied creature
- Slight mid-frequency emphasis (the “squiddy squeak”) around 1.5–3 kHz
- Fast consonant attacks — the choppy, staccato quality
- Light chorus or very short reverb gives the “wet” texture that reinforces the aquatic creature feel
VoxBooster Inkling Settings
| Parameter | Value |
|---|---|
| Pitch shift | +4.5 semitones |
| Formant shift | +2 (upward; smaller vocal tract) |
| EQ — 1.5 kHz | +3 dB |
| EQ — 3 kHz | +2 dB |
| EQ — 80 Hz | -4 dB (remove chest weight) |
| Chorus depth | 15% |
| Chorus rate | 0.8 Hz |
| Reverb pre-delay | 8 ms (short; don’t overdo) |
Speak in your normal voice, emphasize quick, punchy syllables, and let the effect do the rest. You do not need to fake an Inkling accent — the processing handles the character signature.
Octoling Voice: Smokier Sibling
Octolings are the rival faction turned ally, and their voice in the game is perceptibly different from Inklings — slightly deeper, a bit more husky or smoky, less cartoonish in its energy. Octoling dialogue has more weight and less of the bubbly randomness of Inkling chatter.
VoxBooster Octoling Settings
| Parameter | Value |
|---|---|
| Pitch shift | +2.5 semitones |
| Formant shift | +1.5 (still smaller vocal tract, less extreme than Inkling) |
| EQ — 1 kHz | +2 dB |
| EQ — 3 kHz | +1.5 dB |
| EQ — 150 Hz | +2 dB (slight warmth, separates from Inkling) |
| Chorus depth | 8% |
| Reverb pre-delay | 12 ms |
The key difference from the Inkling preset is dialing back the formant shift and keeping a bit more low-mid body. Octolings sound like adults compared to Inklings, even though both are roughly the same height in-game.
Pearl Voice: Pop Idol, Maximum Chaos
Pearl Houzuki (Off the Hook) is Splatoon 2’s perpetual firecracker — rapid-fire, brash, high-energy, zero filter. Her dialogue screams pop-punk idol at maximum volume. In Splatfest contexts she represents the live performance energy, the crowd-control DJ who keeps the vibe kinetic.
VoxBooster Pearl Settings
| Parameter | Value |
|---|---|
| Pitch shift | +5.5 semitones |
| Formant shift | +2.5 |
| EQ — 2–4 kHz | +3–4 dB (nasal brightness, presence) |
| EQ — 80 Hz | -5 dB (Pearl has minimal chest weight) |
| Compression ratio | 3:1 (punchy, fast attack) |
| Reverb | Minimal — Pearl is dry and in-your-face |
The key to Pearl is the bright, slightly nasal mid-range and the punchy compression. She is a loud voice in a small body. Talk fast. Use short, clipped sentences. The effect does the rest.
Marina Voice: Smooth DJ Control
Marina Ida is the technical counterweight to Pearl — calm, measured, genuinely thoughtful, with a voice that is warmer and more melodic. She is the one you want when the crowd needs to hear the actual information, not just feel the energy.
VoxBooster Marina Settings
| Parameter | Value |
|---|---|
| Pitch shift | +3.5 semitones |
| Formant shift | +1.5 |
| EQ — 1–2 kHz | +2 dB (warmth without nasal edge) |
| EQ — 200 Hz | +1.5 dB (smooth low-mid body) |
| EQ — 5 kHz | -1 dB (reduce Pearl-like brightness) |
| Chorus depth | 10% |
| Reverb | Small room, 15% wet (Marina sounds like she is in a studio) |
Marina is more about tonal balance than extremes. She sits in the mix. Use a more legato, thoughtful speaking style — let the words breathe between sentences. The effect adds the melodic shimmer; your delivery adds the intelligence.
Shiver Voice: Eerie, Cool, Ethereal
Shiver (Deep Cut) is the one Splatoon 3 added who has the most distinct aesthetic. Her fortune-telling stage persona, her swordfish riding, her cryptic delivery — she is the “cool older sister who might be a villain” energy. Her voice has an ethereal, slightly hollow quality that is different from the pop warmth of Off the Hook.
VoxBooster Shiver Settings
| Parameter | Value |
|---|---|
| Pitch shift | +1.5 semitones (Shiver is not a high screamer) |
| Formant shift | +1 |
| EQ — 800 Hz | +2 dB (that slightly hollow, resonant quality) |
| EQ — 3–5 kHz | -1.5 dB (reduce brightness — Shiver is cool, not sharp) |
| Chorus depth | 20% (higher than others — this creates the ethereal spacing) |
| Chorus rate | 0.5 Hz (slow, wide movement) |
| Reverb | Medium hall, 25% wet (Shiver sounds like she is performing in a larger space) |
The chorus and reverb are doing most of the work here. Shiver does not need extreme pitch processing — she needs spatial size and that slow, sweeping shimmer that makes her feel otherworldly. Speak slowly. Use pauses. Let the reverb tail finish its sentence.
Big Man Voice: The Warmest Bass in Splatsville
Big Man (the manta ray) is everyone’s favorite gentle giant. His entire vocal contribution is variations of “Ay” at different emotional intensities, delivered from what is clearly an enormous resonant body cavity. He is the hype man who does it with two letters and somehow means everything.
VoxBooster Big Man Settings
| Parameter | Value |
|---|---|
| Pitch shift | -3.5 semitones |
| Formant shift | -2 (larger vocal tract — manta-ray chest resonance) |
| EQ — 100–200 Hz | +5 dB (the warmth and weight) |
| EQ — 400 Hz | +2 dB (body) |
| EQ — 3 kHz | -3 dB (reduce top-end brightness) |
| Reverb | Large room, 20% wet |
| Compression ratio | 4:1 (Big Man voice is consistent, not punchy) |
The magic of Big Man is restraint. Do not try to make a monster voice — make a warm, round, resonant voice that happens to be very large. Say “Ay” with the inflection you want to convey. A rising “Ay” is excitement. A sustained “Ay” is approval. A quick double “Ay ay” is “absolutely yes.” Your squad will understand.
Splatfest Squad Voice Roles: A Coordination Strategy
The most fun use of voice changing in Splatfest is when your whole squad commits to a bit. Here is a practical squad role distribution for 4-player teams:
| Role | Character | Voice Preset | Job in Call |
|---|---|---|---|
| IGL (in-game leader) | Marina | Smooth + measured | Callouts, rotations, objective updates |
| Hype | Pearl | Loud + bright | Pre-round hype, celebration, tilt warnings |
| Support | Big Man | Deep + warm | Confirms plans with “Ay”, morale support |
| Wildcard | Inkling | High + chaotic | Randomized energy, reacts to everything |
You do not need all four to commit — even one person running a voice effect during Splatfest sets the tone and usually gets everyone else into it by round two.
For coordinating bracket play and tournament Splatfest Discord channels, the Smash Bros Discord bracket voice guide has techniques that carry over directly — especially the hotkey switching and mute/unmute discipline.
Splatfest Lobby Hype: Getting the Most Out of the Event
Splatfest in Splatoon 3 runs across a weekend with three teams competing across multiple time slots. The atmosphere is part of the game — the plaza changes color, the music shifts, the NPCs around Splatsville take sides. Here is how voice effects enhance each phase:
Pre-registration / lobby waiting: This is where the voice bit starts. When your squad is waiting in the lobby, run the voice effect from the moment you jump into Discord. It primes everyone for the match energy.
Between matches (30-second results screen): Keep the effect running. React to wins and losses in character. A Pearl “YEAH LET’S GO” after a 50-3 turf war win or a Big Man “Ay…” after a heartbreaker narrow loss are genuinely memorable squad moments.
Switch announcements (when team rankings update): Pull up the announcement in Discord’s text channel, unmute, and deliver it in character. Marina’s even-keeled reporting voice for score updates is particularly good here.
End of Splatfest (final results): Run the effect for the final call reveal. Whether your team won or lost, character voices make the aftermath feel like the end of a real festival, not just a game closing screen.

Voice Changer Comparison for Splatoon 3 Use
| Tool | Real-Time | Virtual Mic | Preset Library | Formant Shift | No Kernel Driver | Price |
|---|---|---|---|---|---|---|
| VoxBooster | Yes | Yes | Yes (extensive) | Yes | Yes | Free trial / paid |
| Voicemod | Yes | Yes | Yes | Limited | No (driver req.) | Freemium |
| MorphVOX | Yes | Yes | Limited | No | No | Paid |
| Clownfish | Yes | Yes | Very limited | No | No | Free |
| Voice.ai | Yes | Yes | AI-based | Yes | No | Freemium |
For Splatoon character voices specifically, formant shifting matters significantly — the Inkling and Big Man effects depend on it. Tools without formant control will give you pitch shift only, which produces the “chipmunk” problem at the high end. VoxBooster’s formant slider is the key differentiator for character voice work.

Performance and Latency: Will It Affect Your Splatfest?
VoxBooster processes audio locally on your Windows PC using optimized real-time DSP. The latency overhead is 5–15 ms, which is completely imperceptible in conversation (human ears cannot distinguish delays under ~20 ms in a speech context).
The CPU overhead is minimal on any gaming PC built in the last five years. VoxBooster is designed to coexist with games running at full tilt — it does not conflict with OBS, Discord overlay, or gaming peripherals software. The virtual microphone driver uses the standard Windows audio API (WASAPI), which means it is compatible with anti-cheat systems including those used in other Nintendo-published titles on PC.
Your Switch’s internet connection, Nintendo Switch Online service, and Splatoon 3 gameplay are completely untouched by whatever runs on your PC audio path.
Frequently Asked Questions
Can you use a voice changer directly in Splatoon 3 on Nintendo Switch?
No. Splatoon 3 does not support voice chat natively on Switch — Nintendo routes voice chat through the Nintendo Switch Online app on your phone. Voice changers like VoxBooster work by creating a virtual microphone on Windows PC, so the practical setup is to run voice chat through Discord on your PC while playing on Switch.
What voice effect sounds most like an Inkling in real life?
Inklings speak in a high-pitched, choppy, wet-sounding dialect. The closest real-time approximation is a pitch shift of +4 to +5 semitones combined with a formant shift upward and a slight chorus or short reverb. A bandpass EQ that boosts the 1.5–3 kHz range adds that characteristic squiddy “squeak” quality.
How do I set up a voice changer for Splatoon Splatfest Discord calls?
Install VoxBooster on your Windows PC, select your real microphone as the input, choose a voice effect preset, then open Discord and set your input device to the VoxBooster Virtual Microphone. Your squad hears your transformed voice in the Discord call while you play Splatoon 3 on Switch normally.
What Big Man voice effect works best for Splatfest hype?
Big Man’s voice is deep, gentle, and repeats “Ay” in a rounded, manta-ray-chest resonance. A pitch shift of -3 to -4 semitones, a low-mid boost around 120–200 Hz, and a short reverb tail capture that warm bassy feel. Keep it soft in the mix — Big Man energy is supportive, not aggressive.
Does using a voice changer affect Nintendo Switch Online or Switch gameplay?
No. Your voice changer runs on your Windows PC and only affects audio sent through your PC microphone into Discord or a phone app. The Switch console and its online connection are completely separate. There is no risk of a ban or penalty from Nintendo for using a voice effect on a third-party voice chat app.
Which Splatfest team voice should I use — Pearl, Marina, or Shiver?
It depends on your team pick. Pearl’s voice is sharp, high-energy, and chaotic — great for +5 to +6 semitone female pop-idol energy with a nasal bite. Marina’s voice is smoother and more melodic — +3 to +4 semitones with less nasal edge. Shiver is ethereal and cool — try a slightly lower pitch with a gentle chorus effect.
Will a voice changer cause lag or audio dropout during Splatfest?
A well-optimized real-time voice changer running locally on your PC adds 5–15 ms of audio latency, which is imperceptible in conversation. It does not interact with your Switch’s network connection at all. The only risk is CPU overhead on a very low-end PC — on any mid-range gaming PC from the last five years, VoxBooster runs without affecting frame rate or network performance.
Conclusion
The splatoon 3 voice changer setup described here takes about ten minutes to configure and adds a genuine layer of personality to Splatfest weekend. Inkling voices for general squad chaos, Octoling for that slightly more composed sibling energy, Pearl for the win celebrations that need to be heard across the whole server, Marina for the team lead who keeps rotations clear, Shiver for the mysterious wildcard, and Big Man for that perfect resonant “Ay” that means everything without needing more words.
The technical path is straightforward: VoxBooster on Windows, Discord as your voice platform, Switch doing the actual gameplay. No kernel drivers, no anti-cheat conflicts, no Switch-side risk.
If you want to extend the voice changing setup across other Nintendo titles, the Mario Kart World voice changer guide and Animal Crossing Discord visit guide are the natural next reads — same Discord infrastructure, different character energy for each community.
