Model Overview

This model can convert Korean text into natural speech and is suitable for speech synthesis applications.

Model Features

High-quality Speech Synthesis

Utilizes the JETS architecture to generate natural and fluent Korean speech.

End-to-end Training

The entire system is trained end-to-end, simplifying the complex processes of traditional TTS systems.

Korean Language Optimization

Specially optimized for Korean speech characteristics, using g2pk for Korean text processing.

Model Capabilities

Korean Text-to-Speech

Speech Synthesis

Use Cases

Voice Assistants

Korean Voice Assistant

Provides natural speech output for Korean voice assistants.

Audiobooks

Korean Audiobook Generation

Automatically converts Korean text content into speech.

🚀 ESPnet2 TTS Model

This ESPnet2 TTS model is designed for text - to - speech conversion. It was trained using the kss recipe, providing high - quality audio output.
