About this tool

Purpose: FlowSpeech is an AI-driven text-to-speech (TTS) studio for content creators, digital marketers, and educators, used to generate near-human-level audio, such as video dubbing, etc.

Main capabilities: The engine can understand context and automatically analyze the emotion, rhythm, and nuances of the script; it supports 30 voices, divided into four categories: serious news, energetic marketing, warm narration, and expressive characters; standard voices cover more than 100 languages, including English, Chinese, Japanese, and Korean, and language coverage varies by voice feature; a single render supports up to 100k characters, making it convenient for long-form content; it can directly read PDF, WORD, PPT, TXT, RTF, EPUB, and image files and convert them into audio.

How to use: First select the generation mode (single speaker for monologue, multi-speaker for dialogue, instant speech for quick generation); paste the script text or upload the above files; enter "['" to open the command panel, where you can add emotion or accent tags, or insert pause tags such as [⌛1.0s] to control rhythm; finally choose a suitable voice from the 30 voices. In single-speaker mode, you can click Add Emotion Tags to automatically insert contextual emotion prompts; in multi-speaker mode, different speakers are automatically detected and split, and suitable AI voices are matched for each segment.

Limitations: The materials mention common questions such as custom voices, commercial use, whether it is free, and data security, but do not provide specific answers to these questions, and the relevant details are not yet available.
