About Japanese Text-to-Speech
Japanese text-to-speech converts written Japanese into natural, expressive speech instantly. Spoken by 125 million people and central to one of the world's largest digital-content markets, Japanese is a top language for narration, e-learning, VTuber and anime-style content, and accessibility. SpeakSwap reads kanji, hiragana, and katakana aloud with lifelike AI voices and several tones to choose from — no subscription, pay only for what you generate.
Getting natural Japanese speech
Japanese is a pitch-accent language with a steady, syllable-timed rhythm, and the same kanji can have several readings depending on context. SpeakSwap's Japanese voices resolve readings in context and apply natural pitch accent, so 今日 is read 'kyō' (today) where it should be — not mis-read character by character. Mixed Japanese-and-English text is handled smoothly too.
