Understanding Japanese OGX files
Standard Japanese (hyojungo), based on Tokyo speech, dominates broadcasting and education and is the variety speech recognition models are primarily trained on. Kansai dialect (Osaka and Kyoto) is the most prominent regional variant, with different pitch accent and vocabulary, while Tohoku and Kyushu dialects diverge further from the standard; the traditional Ryukyuan languages of Okinawa differ so much that linguists classify them as separate languages rather than Japanese dialects.

Frequently asked questions
How to improve the accuracy of your Japanese transcripts?
Start by improving the quality of the Japanese OGX file that you upload to Sonix. Please use high quality recording equipment, recording in a quiet environment, and ensure that your speakers are speaking clearly to ensure that your transcript is as accurate as possible.
Any advice for the Japanese OGX file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Japanese OGX file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from OGX, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Japanese with Sonix:
Why won't my OGX file play on my computer?
OGX files rely on Xiph.Org codecs that are not preinstalled on every operating system. Players such as VLC include these codecs, or you can install a Xiph codec pack for your default player.
How do I get subtitles from an OGX video?
Upload the OGX file to a transcription service, review and edit the generated transcript, then export it as an SRT or VTT subtitle file with timestamps.
Can Sonix transcribe Japanese audio and video to text?
Yes. Upload your audio or video file, select Japanese as the spoken language, and Sonix returns a transcript in standard Japanese script (kanji, hiragana, and katakana) that you can edit in the browser and export.
Does Japanese transcription handle Kansai dialect and regional accents?
Sonix's Japanese model is built around standard (Tokyo) Japanese and generally handles regional accents, but strongly dialectal vocabulary such as Kansai-ben expressions may need corrections in the built-in editor.
Can Sonix create Japanese subtitles?
Yes. After transcribing, you can split the Japanese transcript into subtitle lines and export SRT or VTT files for video captioning.
