Context-aware text to speech with real emotion and pause control
The engine reads sentiment and nuance in your script and automatically applies fitting emotion, from joy and sorrow to excitement.
Type tags like [whisper], [shout], or an accent in brackets, and insert pause markers such as [⌛1.0s] to control pacing exactly.
FlowSpeech detects different speakers, splits the script, and assigns a suitable voice to each segment for instant podcasts and audio drama.
Generate very long scripts in a single pass without chopping chapters, ideal for audiobooks and course material.

Describe what you want in natural language and Noty writes the script, casts voices from the library, directs each line and returns finished audio — asking before it spends your credits.
A searchable library organised by accent, gender, age and best-fit use case, with 18+ voice styles and multilingual star voices that speak every supported language.
On paid plans, record a short sample and read a consent sentence to create a private clone of your own voice that can be cast on any production.
Produce narration, two-host podcasts, audiobooks, songs and instrumentals, narrated .pptx decks, and SRT/VTT dubbing aligned to timecodes.
