Podcast recording platform, Podcastle, has launched its new AI text-to-speech model, Asyncflow v1.0.

The platform also introduced an application programming interface (API) for developers to incorporate this model into their applications.

Asyncflow v1.0 boasts over 450 AI-generated voices capable of narrating text.

The model offers lower training and inference costs than competitors like ElevenLabs and Speechify, targeting marketing, education, and content creation.
