Audify AI

Audify AI is a browser based text to speech converter. You paste text, pick a voice, and it produces natural sounding speech that you download as an audio file. It suits voiceovers for video, podcasts, audiobooks, tutorials and accessibility uses, where recording a human narrator would take more time or money. The tool offers a choice of models, labelled Latest, Stable 1 and Stable HD, and a set of named voices including Alloy, Ash, Coral, Echo, Fable, Onyx, Nova, Sage, Shimmer, Ballad, Verse, Marin and Cedar. Speed can be set from 0.25x to 4x, and output formats include MP3, OPUS, AAC, FLAC, WAV and PCM. With the Latest model you can add a voice instruction to guide style. The interface is translated into around twenty languages, and an estimated character count, token count and cost are shown as you type. Pricing is usage based with no subscription. If you supply your own OpenAI API key, the site says Audify AI is free to use. Without a key, you get 3 free conversions, described as a value of $1.50 in total, then you add a balance to your account starting at $2 USD. The rate is $0.009 USD per 1,000 characters, rounded up to the nearest cent, and payments are processed through Stripe by credit card or digital wallet. The cost of each run is shown before you submit. The voice names and options indicate the service is built on OpenAI's text to speech models.
