Listen first
Hear Japanese before you type
Each sample below is the same Japanese sentence, read by a voice trained on Japanese. Play a few — the difference between two voices in one language matters more than any description of them. Selecting one loads it into the generator above.
Yuki
Japanese, warm
Aoi
Japanese, storytelling
Haruto
Japanese, steady
The sentence being read: “こんにちは！これはAI音声ジェネレーターです。テキストを入力して、自然な声で聞いてみましょう。”

What Japanese asks of a speech engine
Japanese distinguishes words by pitch accent: 箸 (chopsticks) and 橋 (bridge) are the same syllables with a different pitch pattern. An engine that reads Japanese with English-style stress instead of pitch produces something intelligible from context and immediately identifiable as foreign — which is why a voice trained on Japanese matters more here than in most languages, and why we did not offer Japanese until we had one.
The other difficulty is kanji. Most characters have several readings, and choosing between them depends on the word and sometimes the sentence — 生 alone has more than ten. Names are the worst case, since personal and place names often use readings that appear nowhere else. If a name matters, write it in kana in your script: the reading becomes unambiguous and the engine says it correctly. The same trick fixes Latin-script product names, which are otherwise read as English rather than as the Japanese pronunciation your audience expects.
Punctuation carries more weight in Japanese than the character count suggests. Japanese does not use spaces, so the reading rhythm comes almost entirely from 、 and 。 — an engine given a long sentence with no internal punctuation will run the clauses together with nowhere to breathe. Adding a 、 where you would pause when speaking is the fastest way to fix a reading that sounds rushed, and it costs one character. Japanese also has no reliable relationship between character count and spoken length, so time a sample rather than estimating from the script.
