AI Voice Conversion for Online Tabletop RPGs

Echo is a free Roll20 voice changer and tabletop soundboard for online RPG sessions. As a Dungeon Master, you voice merchants, villains, guards, dragons, and nervous innkeepers. As a player, your character deserves a voice that matches their backstory. Echo uses RVC technology, a neural network that reconstructs your voice as a different person in real time, while EchoDeck lets you trigger custom sounds for taverns, spell casts, monster reveals, doors, clues, combat starts, and dramatic stingers. It works with Roll20 integrated voice, Discord, Foundry VTT, and any virtual tabletop that uses a microphone.

Features

Why Tabletop RPG Players Choose Echo

🐉

NPC Voice Library

DMs can pre-load multiple voice models and switch between them — a gruff dwarf tavern keeper, a sinister lich, an elven princess. Each NPC gets a distinct, consistent voice across every session. Import any .pth model from the RVC community.

Player Character Voice

Your Tiefling warlock or halfling rogue deserves a voice that matches their character sheet. AI voice conversion changes your full voice identity — not just pitch — creating a believable character voice you can sustain for entire sessions.

Tabletop Soundboard

Trigger spell sounds, monster roars, tavern ambience, clue reveals, door knocks, battle stingers, or inside jokes without hunting through browser tabs.

Cross-Platform Compatible

Works with Roll20, Foundry VTT, Owlbear Rodeo, Discord, Zoom — any voice chat your table uses. Echo is a system audio device, not a platform-specific plugin.

Voice Models

Voice Models for RPG Characters

Echo supports any .pth voice model from the RVC community. Tabletop RPG players use models to create consistent character voices — wizened old wizards, battle-hardened warriors, ethereal fey creatures, suspicious nobles, or exhausted shopkeepers. DMs often maintain a small library for recurring NPCs, then use the soundboard for moments that should be heard rather than voiced: spell impacts, monster reveals, ominous doors, or a tavern going quiet before a fight.

How AI Voice Technology Transforms Tabletop RPGs

Traditional voice changers apply pitch shifting — making your voice higher or lower. For tabletop RPGs, that can feel limited because a whole cast of NPCs needs more than one squeaky or deep filter. Echo uses RVC voice conversion, an AI voice changer technology powered by deep learning neural networks. The AI preserves your acting performance — emotion, emphasis, and dramatic timing — while changing the voice identity. EchoDeck handles the sounds that are not voices: spell hits, creature noises, ambience, and reveal stingers. Together they make a campaign easier to follow without forcing the DM to juggle five separate audio apps.

Roll20 Voice Changer and Soundboard Ideas

Use Echo to give recurring NPCs consistent voices, make villains sound more threatening, give player characters a voice that matches their class, or add quick creature voices during combat. DMs can keep a small voice lineup ready before the session — narrator, merchant, monster, noble, villain — plus soundboard cues for initiative, spell casts, crits, door knocks, tavern ambience, and boss reveals.

Build a Full Tabletop Voice Setup

Add a Soundboard

Trigger short tavern sounds, spell effects, monster noises, or dramatic stingers during a session.

Use AI Character Voices

Import or train voice models for recurring NPCs, player characters, and campaign villains.

Prep Audio Like You Prep Encounters

The best Roll20 soundboard is planned, not improvised mid-session. Before game night, pick the voices and sounds that match the scenes you actually expect: a merchant voice, a villain voice, one creature voice, a tavern bed, a battle start, a spell hit, and one reveal sting. If a session is rules-heavy, use fewer effects. If it is roleplay-heavy, let voices carry more of the scene. Players remember audio when it reinforces the story, not when every action gets a random noise.

Pro Tip

Keep Roleplay Voices Easy to Follow

Tabletop sessions are about shared story, not audio chaos. Use hotkeys sparingly, label your NPC voices before the session, and keep effects lighter during rules-heavy moments. If your table uses Discord instead of Roll20 voice chat, set Echo in Discord and leave Roll20 focused on maps and sheets.
