Amazon Polly is the AWS option, priced and built for developers. It offers four voice types: Standard at $4 per 1 million characters, Neural at $16, Generative at $30 and Long-Form at $100, the last designed for natural narration of longer content such as articles. The free tier is generous for Standard voices, at 5 million characters a month, while Neural, Long-Form and Generative free allowances apply only for the first 12 months. Polly supports SSML for phrasing, emphasis and intonation, custom lexicons for names and acronyms, and Speech Marks to sync audio with on-screen text. Organizations that want an exclusive voice can commission one through a Brand Voice engagement with the Polly team. What Polly lacks is a creator workflow: there is no voiceover editor, voice cloning is not self-serve, and AWS describes its catalog as dozens of voices, fewer than Google lists. It is a dependable, cheap engine for apps already running on AWS.

Who it is for

Teams on AWS that need cheap, scalable speech for apps, IVR and article audio.

Price
