What is the text length limit?

Up to 4,096 characters per generation. For longer content, split into sections and concatenate the downloaded files.

What is the difference between OpenAI and Polly?

OpenAI TTS has 6 expressive voices that excel at conversational content. Polly offers more voices and languages, ideal for localised or narration use cases.

What are neural voices?

Neural voices use deep learning to produce more natural intonation, phrasing, and emotion compared to standard concatenative TTS.

Can I use the audio commercially?

Usage rights depend on your subscription plan. Free tier audio is for personal use only. Paid plan users may use audio commercially, subject to the OpenAI and Amazon Polly usage policies.
