Study in Japan with confidence
Japanese is spoken by more than 125 million people worldwide, primarily in Japan, with speakers around the world. For students, that means encountering Japanese in lecture halls, seminars, online classes, and study groups.
Traditional transcription tools struggle with real-world Japanese — fast academic speech, regional accents, technical terminology, and overlapping voices. Soniox App understands Japanese as it's actually spoken: in context, instantly, and with the precision students need to study from their notes.
Live university lectures
Capture every word in real-time, even in large Japanese-speaking classrooms with echo, background noise, or fast-paced delivery. Soniox App transcribes it all so you can listen and absorb instead of scrambling for notes.
Online classes
Your Japanese Zoom sessions don't disappear when the call ends. Soniox App captures live sessions and turns them into a permanent text record you can revisit anytime.
Study groups & tutoring sessions
Know exactly who said what with built-in speaker separation. Review Japanese explanations and Q&A later, word for word, no matter how fast the conversation moved.
Guest speakers or panels
Every Japanese guest speaker brings unique insight you won't find in a textbook. Soniox App transcribes it all in real-time so nothing gets lost between the talk and your notes.
Multilingual classrooms
Studying Japanese as a second language, or in a classroom that mixes languages? Soniox detects mid-sentence language switches and provides real-time translation.
Notes & exam preparation
Soniox App turns Japanese lectures into searchable notes you can review, highlight, and study from before exams. Nicely formatted, no cleanup needed.
Note-taking shouldn't get in the way of learning Japanese
Soniox App captures every word so you can focus on engaging, asking better questions, and getting the most out of every Japanese lecture.
Study smarter with AI highlights

Send Japanese transcripts and highlights to classmates, tutors, or study groups with one tap. Soniox formats and punctuates automatically, so your notes always read cleanly — no editing or cleanup needed.
