FlowSpeech

Context-aware text to speech with real emotion and pause control

Context-aware emotion delivery

The engine reads sentiment and nuance in your script and automatically applies fitting emotion, from joy and sorrow to excitement.

Inline emotion and pause tags

Type tags like [whisper], [shout], or an accent in brackets, and insert pause markers such as [⌛1.0s] to control pacing exactly.

Multi-speaker auto casting

FlowSpeech detects different speakers, splits the script, and assigns a suitable voice to each segment for instant podcasts and audio drama.

Long-form rendering up to 100k characters

Generate very long scripts in a single pass without chopping chapters, ideal for audiobooks and course material.
