How many characters can I input per TikTok TTS generation?
Full Answer
IFY Hub's TikTok TTS tool accepts up to 300 bytes per request - roughly 300 English characters or 100 Chinese characters. This comes from the TikTok voice engine's API limit; longer inputs are rejected. For long scripts, split into chunks, generate each, then splice in your editor. Split at sentence boundaries rather than mid-word so the result sounds natural. Pace and pauses can be adjusted during editing, so chunking won't hurt rhythm.
