About

Speech in Flow is an experimental feature in Flow, Google's AI filmmaking tool. Powered by the Veo 3 model, it adds custom AI-generated spoken dialogue to videos created from a single starting image, so a still picture can become an animated scene with characters that talk.

It removes the need to record or edit audio separately when building short narrative clips from images.

It is aimed at filmmakers, storytellers, and creators using Flow who want to bring images to life with dialogue as part of an AI-assisted production workflow, rather than adding voice in a separate step.

Why we picked it

Speech in Flow fills a specific gap in image-to-video tools — adding AI-generated dialogue to a scene built from a single still image, so a character talks without ever recording or editing audio separately.
