What is it?

Edge TTS Voice Studio is a Windows desktop client for Microsoft Edge text-to-speech voices. You paste an article, script or subtitle draft, or import txt, md, docx and pdf files, and export the result as an MP3. It needs no API key and is built on the open-source edge-tts library.

The app offers three work modes: Normal for one full text, Page for splitting content on [分页] markers into one audio per page, and Line for one audio file per non-empty line. Normal mode can also batch-process multiple files with per-file voice and pause settings, and completed items are kept when you retry.

For editing and review, it provides independent sentence pauses in milliseconds, optional SRT subtitles, a timeline JSON with sentence start and end times, live sentence highlighting during playback, and a result window with per-row playback, draggable progress and regeneration. A Language, Gender, Voice picker, a bilingual Chinese and English interface, proxy-aware network checks and stall recovery round out the tool.
