Voice Studio is one of the widest feature demos in the repo. It shows how one product can wrap a provider like ElevenLabs into several useful user-facing tools instead of exposing a single narrow endpoint.

​
What Your Users Can Do

  • Turn text into speech with multiple voice options
  • Browse available voices
  • Transform one voice recording into another voice
  • Generate sound effects from text
  • Generate music from text prompts
One product shell, five audio workflows. That’s the power of this app.

​
Voice Modes

Type text, pick a voice, and generate speech. The app supports multiple ElevenLabs models:
  • eleven_v3
  • eleven_multilingual_v2
  • eleven_flash_v2_5
  • eleven_turbo_v2_5
It also supports emotional prompt tags, which makes the output feel way more natural and productized than a raw text box.

​
API Surface

The app exposes five routes:
  • voices — browse available voice options
  • text-to-speech — generate speech from text
  • speech-to-speech — transform one voice into another
  • music — generate music from prompts
  • sound-effects — generate SFX from descriptions

​
What You Need

Better Auth + PostgreSQL

Auth and generation history

Storage

Saved audio outputs

ElevenLabs

Powers the entire voice generation stack

​
How It Works

1

Pick a mode

The user selects a tab — TTS, voice transform, music, or sound effects.
2

Enter input

Depending on the mode: type text, upload audio, or describe what you want.
3

Generate

The app sends the request to ElevenLabs with the right parameters for the selected mode.
4

Store the result

The generated audio file is uploaded to object storage.
5

Listen and revisit

The result is saved so the user can replay it, download it, or come back to it later.

​
Great Starting Point For…

  • Voiceover tools
  • Podcast utility products
  • Sound design generators
  • AI jingle or music tools
  • Dubbing or accessibility workflows
The boring product pieces — auth, credits, saved outputs, playback history — are already handled for you.

​
Good First Customizations

  • Which tabs are visible
  • Default ElevenLabs model choices
  • Credit pricing
  • Prompt presets
  • Branding and copy

​
Verification

Your setup is working if:
  • Voices load from ElevenLabs
  • Text-to-speech returns playable audio
  • Sound effects and music generation both save correctly
  • Speech-to-speech works with an uploaded sample
