Japanese text to speech across kanji, kana, and pitch accent
Japanese is spoken by around 125 million people and written with three systems at once — kanji, hiragana, and katakana — frequently mixed inside a single sentence and with no spaces between words. That combination makes it one of the harder languages to voice well. A kanji can have several readings depending on context, there are no boundaries telling the engine where one word ends and the next begins, and pitch accent quietly decides which word you actually said.
Notevibes generates Japanese in the ja-JP locale with neural voices that read mixed scripts, respect pitch accent, and match the level of politeness the text calls for — the difference between a voice that sounds Japanese and one that merely pronounces Japanese.
Three scripts and no spaces
Kanji carry meaning but not a single fixed reading — the same character shifts between its on’yomi and kun’yomi depending on the word, so the engine has to interpret rather than transliterate. Katakana handles loanwords and names, hiragana glues the grammar together, and because nothing separates the words, the first job is segmenting the sentence correctly. Japanese is also mora-timed, giving it an even, clipped rhythm that a good voice preserves instead of stretching syllables the English way.
Pitch accent and levels of politeness
Japanese is a pitch-accent language, not a stress language: where the pitch rises and falls can change the word entirely — hashi is bridge, chopsticks, or edge depending on the contour. Politeness is just as load-bearing. The polite desu/masu register suits corporate and customer-facing content, while plain forms fit casual or younger-audience material, and a voice that mixes them sounds off. Matching register to context is part of sounding fluent.
Standard Tokyo, Kansai, and beyond
Standard Tokyo is the broadcast and corporate default, expected in formal and business content. Kansai (Osaka) brings a lively, melodic warmth well suited to entertainment, and Kyushu adds its own regional pitch patterns. Across anime, gaming, e-learning, and corporate communication in one of the world’s largest digital economies, plain-words direction and a persona line shape the performance, and MP3 or WAV export with a commercial license readies it for release.
