Understanding Japanese WMV 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 WMV 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 WMV file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Japanese WMV file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from WMV, 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 WMV file play on my Mac?
macOS does not include Microsoft's WMV codecs, so QuickTime cannot open the file natively. You can play it with a third-party app such as VLC, or convert it to MP4 for broader compatibility.
Can I get subtitles from a WMV video?
Yes. After uploading and transcribing the WMV file, you can export the transcript as an SRT or VTT caption file with timestamps aligned to the video.
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.
