Clownfish Voice Changer has been around for years and remains one of the most-searched free tools in the voice-changer space. It is lightweight, unobtrusive, and genuinely works — which is more than can be said for a lot of freeware. This guide walks through the full setup on Discord and TeamSpeak, explains every effect option, covers common problems and their fixes, and then gives you an honest comparison against VoxBooster so you can decide which tool fits your situation.
What Is Clownfish Voice Changer?
Clownfish Voice Changer is a free, system-wide Windows audio utility that installs a virtual audio driver and exposes a virtual microphone to every application on your PC. Unlike software that works as an insert effect inside a single app, Clownfish sits between your physical microphone and any program that reads audio. That makes the setup straightforward: you install it once, and every app that listens to a microphone can receive the processed voice.
The core feature set focuses on pitch and timbre manipulation. You get a continuous pitch-shift slider, a handful of voice presets (Robot, Alien, Baby, Mutation, Male-to-Female, Female-to-Male, Atari, Custom), and a basic text-to-speech panel. There is also a media player component for playing audio files into the virtual microphone, which doubles as a rudimentary soundboard.
Clownfish does not use machine learning. Its effects are all classic DSP: pitch shifting with formant correction, ring modulation for the robot sound, and similar. That is relevant when you see terms like “AI voice changer” online — Clownfish does not qualify. The tradeoff is that it is predictable, fast, and works on very old hardware.
System Requirements and Download
Clownfish supports Windows 7 through Windows 11 (32-bit and 64-bit). It has almost no hardware requirements — even a budget laptop handles it without issue. The installer is around 5 MB.
Official download: always use the official site at clownfish-translator.com. Avoid mirrors and third-party aggregators; the installer has been repackaged with adware on several of those sites.
The installer is unsigned by a well-known CA, so Windows SmartScreen will flag it on first run. That is normal for this particular tool. Click “More info → Run anyway” if you trust the source. If you are not comfortable bypassing SmartScreen, that is a fair reason to look at alternatives.
Installing Clownfish Step by Step
- Download the installer from the official site.
- Run the installer as Administrator. SmartScreen may warn you — choose “More info” then “Run anyway”.
- Complete the wizard. Accept the license, leave the default install path, and let it install. It will register the virtual audio driver.
- Restart is not required, but if the virtual device does not appear in your audio settings immediately, a restart clears it up.
- Look in the system tray. Clownfish adds a small fish icon in the notification area. Right-click it to open the settings.
During installation you may see a driver installation dialog with “Install” and “Don’t Install” buttons. Click Install. Without the driver, the virtual microphone device will not be created.
Configuring Clownfish
After installation, right-click the tray icon and select Settings (or Voice Changer depending on your version). The main window has several tabs:
Input Device
Set this to your physical microphone — the device you speak into. Clownfish will read from this device and apply effects before routing output to the virtual microphone. If you skip this step, Clownfish defaults to the Windows default device, which may or may not be correct.
Voice Changer Tab
This is where you toggle processing on/off and pick effects. The main controls are:
- Voice Changer toggle — global on/off switch
- Pitch — a slider from roughly -12 to +12 semitones. Negative values make your voice deeper; positive values raise the pitch toward a chipmunk register.
- Preset list — Robot, Alien, Male, Female, Baby, Mutation, Atari, Custom. Click one to apply it instantly.
The Custom preset lets you combine a pitch value with a secondary modulation type. It gives you a bit more creative room, though the options are still limited compared to what dedicated tools offer.
Text to Speech (TTS)
Clownfish has a built-in TTS engine that speaks text through the virtual microphone. You pick a voice from the Windows SAPI voices installed on your system. This is useful for accessibility scenarios or for trolling purposes if you prefer typed messages over live speech.
Media Player / Soundboard
The media player can load and play audio files directly into the virtual microphone stream. There is no hotkey trigger panel, so it is not a true soundboard — you need to keep the window open and press play manually. For a proper hotkey-triggered soundboard, you would need a separate tool.
Setting Up Clownfish on Discord
Discord has its own microphone input selector, which you must point at the Clownfish virtual device.
- Open Discord and go to User Settings (gear icon near your avatar).
- Click Voice & Video in the left sidebar.
- Under Input Device, open the dropdown. You should see “Microphone (Clownfish Wave In)” or similar wording. Select it.
- Click Let’s Check to test. Speak into your microphone and verify that Discord picks up audio.
- Make sure Echo Cancellation, Noise Suppression, and Advanced Voice Activity are all Off in Discord. These DSP features fight with Clownfish’s processing and often cause garbled audio or dropout.
- Back in Clownfish’s tray icon, ensure Voice Changer is toggled On and select the effect you want.
At this point, everyone in your voice channel will hear the effect. If you only want to use an effect sometimes, you can right-click the Clownfish tray icon mid-session and toggle it off — the switch takes effect in under a second.
A note on Discord’s own noise suppression: Krisp (Discord’s built-in suppressor) and Clownfish are not always friendly. If you notice stuttering, the first fix is to disable all of Discord’s audio processing under Settings → Voice & Video → scroll to “Advanced”.
Setting Up Clownfish on TeamSpeak
TeamSpeak lets you choose your capture device independently of the Windows default, which makes the setup clean.
- Open TeamSpeak and go to Tools → Options → Capture.
- Under Capture Device, open the dropdown and select “Microphone (Clownfish Wave In)”.
- Set Activation to either Voice Activity Detection or Push-to-Talk based on your preference.
- Click Apply, then OK.
- Use the Whisper/Echo Test button in TeamSpeak Options to verify your processed voice comes through.
TeamSpeak’s capture pipeline applies very little post-processing by default, which means Clownfish effects tend to come through cleaner on TeamSpeak than they do after Discord’s DSP stack.
Troubleshooting Common Problems
”Microphone (Clownfish Wave In)” Does Not Appear
- Open Device Manager and check under Sound, video and game controllers for the Clownfish virtual device.
- If it shows a yellow warning, right-click → Uninstall Device, then re-run the Clownfish installer as Administrator.
- Check that Windows did not disable the device under Sound → Recording tab → right-click on empty space → “Show Disabled Devices”.
Voice Sounds Robotic or Distorted
- Make sure you are not using the Robot preset unintentionally.
- Check that no other app (Zoom, OBS, NVIDIA RTX Voice) is also processing the same microphone input.
- Reduce the pitch shift value. Going beyond ±6 semitones starts producing artifacts with most presets.
Echo or Feedback Loop
- Never use Clownfish’s virtual output as both your capture device and playback device. That creates a feedback loop.
- If you hear yourself echoing, check that your speakers are not leaking into your microphone and that Discord’s echo cancellation is off (see the Discord section above — you want Discord’s EC off, not on, when using Clownfish).
App Does Not Detect the Virtual Microphone
Some apps ignore non-default audio devices. As a workaround, go to Windows Settings → System → Sound → Input and set the Clownfish virtual device as your Default Input Device system-wide. This forces all apps to use it.
Anti-Cheat Conflicts
Clownfish installs a system-level audio driver. Anti-cheat systems like VALORANT’s Vanguard or games using Easy Anti-Cheat occasionally block or flag third-party drivers. If you experience crashes or bans after installing Clownfish, uninstall it before playing those titles. This is not a hypothetical — several community threads document this on competitive FPS titles.
Clownfish Tips for Discord & TeamSpeak
- Keep pitch shifts modest. Shifts of ±3–4 semitones are more convincing than ±10, which sounds electronic regardless of which preset you combine it with.
- Layer effects cautiously. Clownfish lets you combine pitch shift with a modulation preset. The results can be compelling but they can also clip badly at volume. Monitor your levels.
- Use push-to-talk when possible. Because Clownfish processes all audio from the mic input — including ambient sound — push-to-talk prevents room noise from leaking during pauses.
- Save custom presets by adjusting the pitch slider to a value you like and then right-clicking the preset list to save. This is not well-documented in the UI.
Clownfish vs VoxBooster: Honest Comparison
Clownfish and VoxBooster are aimed at somewhat different users. Here is a factual side-by-side.
| Feature | Clownfish | VoxBooster |
|---|---|---|
| Price | Free | Paid (trial available) |
| Platform | Windows 7–11 | Windows 10–11 |
| Installation | System driver | App + WASAPI (no kernel driver) |
| Anti-cheat safety | Risk with some titles | WASAPI-only, no kernel driver |
| Voice effects | ~8 presets + pitch slider | Voice effects + pitch + custom |
| AI voice cloning | No | Yes — real-time neural voice conversion |
| Noise suppression | No | Yes — local AI suppression |
| Soundboard | Basic (no hotkeys) | Yes — hotkey-triggered |
| Text-to-speech | Yes (SAPI) | Yes (neural TTS) |
| Dictation / transcription | No | Yes — local Whisper transcription |
| Latency | Very low | Low (WASAPI direct, local processing) |
| Works in Discord | Yes | Yes |
| Works in TeamSpeak | Yes | Yes |
| Works in any WASAPI app | Yes (via virtual device) | Yes (via WASAPI loopback) |
The most relevant differences for competitive gamers and streamers: Clownfish’s driver model can conflict with anti-cheat software, while VoxBooster routes audio through WASAPI directly without touching the kernel driver layer. For streamers who want AI voice cloning in real time during a live session — something Clownfish simply cannot do — VoxBooster’s neural voice conversion is the reason to switch.
For users who only want basic pitch shifting and do not need anything else, Clownfish does the job and costs nothing.

When Clownfish Is the Right Choice
Clownfish makes sense when:
- You want to change your voice for fun with zero budget.
- You are on an older machine or older Windows version.
- You only need basic pitch shifting, not AI-driven conversion.
- You are not playing games with aggressive anti-cheat.
- You want something minimal that does not sit in the background consuming resources.
There is no shame in using free software that works. Clownfish is in that category.
When You Should Consider an Alternative
Consider moving to a different tool if you encounter any of these situations:
- Your anti-cheat software flags Clownfish’s driver on game launch.
- You want to clone a specific voice rather than apply a filter.
- You need push-to-talk with hotkey-triggered sound effects and automated noise gating in the same workflow.
- You want offline dictation and transcription alongside voice processing.
- You want local, private processing — Clownfish itself does not send audio anywhere, but it also does not include noise suppression, so background audio still leaks to other people.

Frequently Asked Questions
Is Clownfish Voice Changer free?
Yes. Clownfish Voice Changer is completely free and has no paid tier. It installs at the system audio driver level and works with any application that uses a microphone.
Does Clownfish work on Discord mobile?
No. Clownfish only runs on Windows and processes audio at the driver level. The Discord mobile app bypasses Windows audio subsystems entirely, so Clownfish has no effect on mobile.
Why does my voice sound robotic in Clownfish?
The pitch-shift and voice effects in Clownfish use basic DSP algorithms that can sound unnatural at extreme settings. Lower the pitch shift, reduce effect intensity, or try the Atari or Male/Female presets at moderate levels.
Is Clownfish safe to use with anti-cheat software?
Clownfish installs a system-wide audio driver, which some anti-cheat systems flag or block. If you play games with aggressive anti-cheat (Valorant, EAC titles), test it carefully or use a tool that does not require a kernel driver.
Can Clownfish do AI voice cloning?
No. Clownfish offers preset voice effects and pitch shifting but does not include AI voice cloning or neural voice conversion. For real-time AI voice cloning you would need a different tool such as VoxBooster.
How do I stop Clownfish from affecting all apps?
Right-click the Clownfish tray icon and toggle the ‘Voice Changer’ option to Off. This disables processing globally without uninstalling. You can also set it per-app by targeting only the Discord or TeamSpeak process in the Clownfish settings.
What is the difference between Clownfish and VoxBooster?
Clownfish is a lightweight, free tool focused on basic pitch shifting and preset voice effects. VoxBooster is a paid Windows application that adds AI voice cloning, a soundboard, noise suppression, dictation, and TTS — all processed locally with low latency via WASAPI, without a kernel driver.
Conclusion
Clownfish Voice Changer earns its reputation as the go-to free option: it installs in minutes, it routes cleanly into Discord and TeamSpeak, and it does not nag you for money. The setup steps in this guide — picking the right input device, pointing Discord or TeamSpeak at the virtual microphone, and disabling conflicting DSP in the receiving app — solve the vast majority of issues people run into.
Where Clownfish shows its age is in depth: no AI voice cloning, no intelligent noise suppression, no real soundboard, and a driver-level architecture that can cause friction with modern anti-cheat software. If those gaps matter to you, VoxBooster was built specifically to address them — local AI voice processing, WASAPI audio routing without a kernel driver, a hotkey-triggered soundboard, and Whisper-powered dictation, all in one Windows application.
