Abstract Components Overview of the ChatTTS application.
The central control unit of the ChatTTS application. It manages the overall text-to-speech workflow, coordinating model loading, asset management, text pre-processing, model inference, and audio output generation. It serves as the primary interface for user interaction.
Related Classes/Methods:
Responsible for preparing raw input text for the speech synthesis pipeline. This involves normalizing text (e.g., handling homophones, character mapping) and converting it into numerical tokens suitable for the core speech models.
Related Classes/Methods:
This composite component encompasses the core neural network models responsible for transforming processed text into audible speech. It includes the Generative Pre-trained Transformer (GPT) for linguistic and prosodic generation, the Digital Variational Autoencoder (DVAE) for acoustic feature manipulation, the Vocoder (Vocos) for waveform generation, and the Speaker Embedding Module for voice control.
