AI Text to Speech
Create AI text to speech from a finished script
Write the passage
Paste up to 5,000 characters of narration. Use complete sentences and punctuation to suggest natural pauses. Break a longer script into passages you can review individually.
Listen to voices and set the delivery
Open the voice picker, search by name or vocal character, and play a sample before choosing. Adjust speed and stability for the passage, then review the credit cost beside the generation button.
Generate, listen and download
Submit your script and follow its task status in Results. Listen to the finished narration before downloading. Revise the script or delivery settings to make another take; each new generation has its own cost.
AI text to speech input and delivery limits
Maximum spoken text per request; a longer script is generated in parts.
Adjust pacing around the default speed of 1.0.
Speed, stability, similarity and style expression.
Shape the voice around your words
Pacing for a tutorial or introduction
Speech speed ranges from 0.7 to 1.2, with 1.0 as the default. Start near normal speed and listen for clear pronunciation before using a faster or slower delivery.
Stable delivery or more variation
Stability, voice similarity and style expression let you guide the performance. A setting is a direction rather than a guarantee: compare generated takes with the same short passage before committing to a long script.
Long scripts and language
Each request speaks up to 5,000 characters. Split a longer script at paragraph breaks, keep the same voice and settings for every part, and listen to the joins. The language setting starts on Auto-detect; choose a language from the list when a short passage or a name could be read in the wrong one.
