audyo.ai vs Google Flow Music (formerly Riffusion)

Audyo converts typed text into downloadable speech through a document-style editor. You write or paste a script, choose from 100+ voices across languages and accents, and export audio for videos, podcasts, presentations, and other projects without recording in a studio.

Most audio tools make you trim waveforms and re-record when a line changes. Audyo keeps the script as the source of truth, so you revise text, swap speakers, and regenerate audio without touching a timeline. That text-first workflow fits creators who treat narration like a draft, not a one-take studio session.

You can build multi-voice conversations, mix languages in one project, set custom pronunciations with phonetics, format scripts with Markdown, and use the built-in assistant to refine copy before generating audio. Audyo lists support for English, French, Spanish, German, Italian, Brazilian Portuguese, Japanese, Korean, Chinese, Hindi, Arabic, Turkish, and Russian, with use cases such as voice-overs, podcasts, audiobooks, and video narration.

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.
