Japanese text to speech with natural intonation
Convert Japanese text into smooth speech. Choose a voice, set the pace, and export audio for videos or lessons.
Readings, pitch accent and pauses
Japanese is hard for TTS because kanji have several readings and pitch accent changes meaning. Doubao Seed TTS 2.0 resolves readings from context, which keeps names, place names and counters correct in most business scripts.
Trailing silence and speech rate controls let you shape the rhythm. For language learners, slowing the rate to -30% to -50% produces clearer mora boundaries without sounding robotic.
Japanese voices and output
