One child voice says Earth · Terre · 地球 · Tierra — exactly one second apart.
5 finalists out of 15 candidates tried, across two engines. Listen on headphones; the differences are in the consonants.
Japanese is where these break. Of 15 candidates, 5 said 地球 wrong — including one that said だいすき ("I love you"). Four of the five purpose-built child voices failed it. Every voice below says it correctly, which is most of why they're here.
The 1-second spacing is exact, not model-guessed — the words are cut and spaced in ffmpeg, verified by arithmetic on every file. Stems are published separately so the editor can re-time to picture.
Same prompt, same pipeline — a voice we didn't vet. For a product whose promise is "hear its name in a new language," a wrong word is the one defect the audience is guaranteed to catch. Every finalist above was transcribed back and checked per language before it made this page.
