SpeechEasy vs Google Flow Music (formerly Riffusion)

SpeechEasy turns written text or a pasted web link into studio-grade synthetic voice audio you can play on desktop or mobile. The marketing site pitches it for listening on the go, at home, or in the office, and for dropping narration into e-learning content without recording a human voice.

Where heavier voice editors pack timelines, SSML, and cloning workflows, SpeechEasy keeps the surface area small: pick a voice, feed it text or a URL, and export audio. The free Starter tier still unlocks the full voice library, which is unusual in a category that often gates premium voices behind paid plans. Paid upgrades route through an in-app Content Creator purchase, while a Marketer tier remains listed as coming soon.

Course builders, marketers on tight video deadlines, and publishers turning articles into listenable files are the clearest fits. The homepage also calls out audiobook-style publishing and stakeholder-ready marketing voiceovers as named use cases.

Google Flow Music lets you create full-length songs, remix tracks, and publish music through a conversational studio built on Google's Lyria 3.5 model. riffusion.com now redirects to flowmusic.app, where you chat with Producer like you are in a session, iterate on vocals and arrangement, and export finished tracks.

Unlike one-shot music generators that spit out a clip and stop, Flow Music focuses on iterative editing. Replace and Extend let you swap specific sections or continue a song past its endpoint without regenerating the whole track. You can also direct Veo-powered music videos, split stems, apply audio effects, and vibe-code custom instruments or mini apps inside Spaces.

The free tier includes daily top-up credits and two concurrent generations with no credit card required. Paid plans raise monthly credits, concurrent generation limits, and add member perks. Google acquired the Riffusion team in 2026 and folded the product into Google Labs alongside Lyria and Veo.
