📃 Overview

Duration: 6/2024 - now (oncoming 🚀)

This project is a sophisticated clone of ElevenLabs' voice AI platform, featuring text-to-speech, voice conversion, and audio generation capabilities. The system self-hosts three state-of-the-art AI models that can be fine-tuned to specific voices, offering users a powerful toolkit for audio content creation. The architecture combines a high-performance Python/PyTorch AI backend with a modern Next.js frontend, all orchestrated through containerized services and efficient queue management.

🧠 AI Models Implementation

  • StyleTTS2: Implementation of a state-of-the-art text-to-speech model capable of generating natural-sounding speech with control over style, prosody, and emotion
  • Seed-VC: Voice conversion model that transforms one person's voice into another while preserving speech content and enhancing naturalness
  • Make-An-Audio: Generative audio model for creating realistic environmental sounds, music, and effects from textual descriptions
  • Fine-tuning Pipeline: Custom training workflow for adapting models to new voices using minimal sample data
  • Inference Optimization: ONNX runtime conversion and quantization techniques for faster generation
  • Voice Cloning: System for creating digital voice replicas from short audio samples
  • Emotion Control: Parameters for adjusting emotional tone and intensity in generated speech
