Voicevox dify plugin

Overview

VOICEVOX DIFY Plugin is a TTS (Text-to-Speech) plugin for the Dify platform that integrates with VOICEVOX, a free Japanese voice synthesis engine. This plugin allows Dify applications to convert text into natural-sounding Japanese speech using various voice models. This plugin is compatible with Dify 1.x.

This plugin works with

• VOICEVOX
• AivisSpeech

Installation

Download voicevox.difypkg in the release section and install it selecting Local Package File in the Plugins section on your Dify console.

Development

Setup
