OSS TanbouOverview
VOICEVOX/voicevox is the desktop editor repository for entering text, choosing speakers and styles, adjusting pronunciation and intonation, and exporting audio. The synthesis engine and core live in separate repositories.
Features and best fit
Based on official documentation; not hands-on tested · Content checked:
Control the synthesis engine through a graphical workflow
The Electron, TypeScript, and Vue editor connects to the VOICEVOX engine API for audio generation. A product build can bundle the engine, while development can target an independently running engine. A browser edition is also under development in the repository.

For detailed GUI control of Japanese synthesized speech
It fits users preparing speaker-specific audio for video, streaming, or applications, along with contributors developing the editor itself. General users should begin with the packaged releases on the official website.

The editor needs an engine and has multiple licensing paths
This repository contains the editor, which requires either the product engine or a running VOICEVOX engine API. The browser edition remains under development and needs a local engine. The editor offers LGPL v3 terms plus a separately obtainable license for distribution without source disclosure.

Supplemental curator note
Selected for a distinct name reinforced across Japanese video credits even though editor, engine, and core are separate and the repository has no GitHub topics.
