Understanding Japanese XSPF 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 XSPF 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 XSPF file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Japanese XSPF file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from XSPF, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Japanese with Sonix:
Can I convert an XSPF file to text?
Not directly, because an XSPF file is a playlist that contains no audio data, only references to audio files. Locate the MP3, WAV, or OGG files it points to, upload those to Sonix to transcribe them, then edit and export the transcript.
How do I find the audio files referenced in an XSPF playlist?
Open the XSPF file in a text editor or a player like VLC; each track's location tag lists the file path or URL of the actual audio file. Those referenced files are what you upload for transcription.
What is the difference between XSPF and M3U playlists?
Both are playlist formats that reference external audio files rather than storing audio themselves. XSPF organizes its entries with structured XML tags, while M3U is a simpler plain-text list of file paths.
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.
