  ## Flowtron: an Autoregressive Flow-based Network for Text-to-Mel-spectrogram Synthesis
  
  ### Rafael Valle, Kevin Shih, Ryan Prenger and Bryan Catanzaro
  
  In our recent [paper] we propose Flowtron: an autoregressive flow-based generative network for text-to-speech synthesis with control over speech variation and style transfer.

  ## Flowtron: An Open-Source Research Model for Advanced Text-to-Speech Synthesis
  
  Flowtron is an autoregressive flow-based generative network designed for high-quality text-to-speech (TTS) synthesis, offering fine-grained control over speech variation and style transfer. This repository provides the research model and code for AI researchers and developers working on advanced deep learning TTS systems.

  ## Key Features
  *   **Flow-based Generative Architecture:** Flowtron utilizes an autoregressive flow-based network for text-to-mel-spectrogram synthesis, enabling exact likelihood maximization for stable and high-quality training.
  *   **Expressive Control:** Gain fine-grained control over speech attributes such as pitch, tone, speech rate, cadence, and accent through latent space manipulation.
  *   **Style Transfer Capabilities:** Perform style transfer between speakers, including those not seen during the initial training phase.
  *   **Research Foundation:** Provides a robust and flexible framework for advanced research and experimentation in generative text-to-speech.
