Stay In Character. Always.
Your real voice stays private. EchoDeck's TTS voice personas let you speak as your VTuber character without ever using your microphone. Type your lines, AI generates speech in your character's voice, and it plays through Discord, OBS, and every voice app. Character-specific soundboards for reactions, emotes, and stream engagement — all in one app.
Built for VTuber Workflows
VTubing is about character immersion. Your avatar is designed, your lore is written, your persona is crafted — but then your real voice breaks the illusion. EchoDeck solves this with AI voice personas that match your character, plus character-specific soundboards for consistent reactions.
🎭 Character Voice Personas
Choose from 100+ AI voices that match your character's personality. High-pitched anime voice for kawaii characters, deep authoritative voice for villains, robotic voice for sci-fi personas. Type your lines and AI speaks them in character — your real voice never enters the stream. Switch between multiple character voices with hotkeys for multi-persona streams.
🔊 Character Soundboards
Create soundboards specific to each character — signature catchphrases, emote sounds, reaction audio, and transition effects. When you switch personas, your soundboard automatically switches too. Community-curated packs include genre-specific collections: anime reactions, fantasy SFX, sci-fi ambience.
🔒 Real Voice Protection
Unlike voice changers that filter your real mic audio (and can be reversed), EchoDeck's TTS approach generates speech from scratch. Your real voice never enters the audio pipeline. There's no acoustic fingerprint to extract, no filter to undo. Complete privacy, not just an effect layer.
📺 Seamless OBS Integration
EchoDeck routes through VB-Cable, which OBS captures as a standard audio source. Independent volume control means perfect balance between your character voice, soundboard audio, and game audio. Works alongside VTuber tracking software without conflicts.
Multi-Persona Streaming
Run multiple VTuber characters in a single stream. Assign each persona a voice, a soundboard, and a hotkey. Switch between them instantly — perfect for collabs, skits, and character interactions.
Create Personas
Set up each character with a unique AI voice, custom soundboard, and personality profile. Name them for easy switching.
Assign Hotkeys
Bind each persona to a hotkey or Stream Deck button. Switch characters mid-stream without opening any menus.
Perform
Type as any character. Voice, soundboard, and persona switch together. Your audience sees seamless character transitions.
Frequently Asked Questions
Can people reverse-engineer my real voice?
No. Unlike voice changers that apply filters to your mic audio, EchoDeck generates speech from text using AI. Your real voice is never recorded, processed, or transmitted. There's no acoustic data to reverse.
Does it work with VTuber tracking software?
Yes. EchoDeck operates independently at the audio level. It works alongside VTube Studio, Animaze, Live2D, and any face/body tracking software without interference. Both apps run simultaneously with no conflicts.
Can I train a custom voice model for my character?
Custom voice model training is on our roadmap. Currently you can choose from 100+ pre-built AI voices and fine-tune parameters like pitch, speed, and tone to match your character's personality closely.
Is there a latency when typing?
Cloud TTS generates speech in under 500ms. Local AI models (NVIDIA GPU) achieve sub-200ms. For VTuber conversation pacing, the delay feels natural — similar to a brief pause before speaking, which actually enhances the character performance.
