VoiceMorph – Personalized Voice Changer Platform

VoiceMorph is a modular, AI-powered voice conversion platform that allows users to record and send their own voice, train a model based on a target speaker, and transform new voice inputs into the target voice.

The system routes conversion tasks to external rvc APIs (currently Replicate), prioritizes them based on user subscription tier, and will eventually migrate to an in-house, cost-efficient inference service.

🔧 Tech Stack

• FastAPI for API server
• Beanie for MongoDB ODM
• Docker / Docker Compose for containerization
• fastapi-mongo-base Python framework (published on PyPI) for scaffolding and development structure
• Replicate (temporary) for voice conversion backend
• Modular app structure supporting task-based execution

🧠 Core Components

• apps.voice:
  Handles management of available target voice models.

  • schemas.py: Data structures for request/response validation
  • models.py: MongoDB voice model definitions
  • services.py: Business logic for managing voice models
  • routes.py: REST endpoints for adding and listing models

• apps.neda:
  Contains the core voice conversion APIs.

  • Accepts voice conversion requests from users
  • Sends tasks to the external RVC backend (Replicate)
  • Selects the appropriate target voice model

• utils.finance:
  Connects to an external finance microservice

  • Fetches user subscription info
  • Prioritizes tasks based on subscription tier

• server.worker:
  Manages periodic background checks on tasks

  • Detects and retries incomplete conversions
  • Handles failure recovery in case of webhook errors
