Lyria 3.5 in another language: prompt in it, then check the song

To get a Lyria 3.5 song in another language, write the prompt and any lyrics in that language. Google's docs say that is how multilingual music is requested (read 2026-10-02). On Sume the same applies through Music Router, where sume/music-auto runs Lyria 3.5 today.

What Google documents

The Gemini API music page lists lyria-3.5 as the full-length model, with a couple of minutes of music controllable from the prompt, and says lyrics and song structure come back alongside the audio (read 2026-10-02). It also notes that results may vary between calls even with the same prompt, that generation is single-turn, and that all audio carries a SynthID watermark (read 2026-10-02).

How to do it on Sume

Send a normal Music Router request with the language named in the prompt and the sung text written in that language. Use section tags or timestamps to give structure, for example [0:00-0:30] Intro:, which the Sume docs list as a way to steer length and layout.

Read result.lyrics after the job completes. The docs describe it as model-reported lyrics or a section map when present, so use it to confirm the words came back in the right language before you caption the track.

Checks before you ship

A prompt in the target language is a request, not a guarantee. Listen for pronunciation and drift, and regenerate if needed; each accepted generation is billed at the fixed Music price.

Google's safety filters block specific artist voices and copyrighted lyrics (read 2026-10-02), so write original lyrics rather than quoting a known song.

Sume's docs do not publish a language list for music, so test the language you need rather than assuming support.
