Understanding Spanish VOB files
Spanish spans two broad families: Peninsular Spanish (Spain) and Latin American Spanish, with notable regional varieties such as Mexican, Caribbean, Andean, and Rioplatense. The most audible differences for speech recognition are Spain's "th" sound for c/z (distinción), the softened or dropped syllable-final "s" in Caribbean speech, and the "sh"-like ll/y of Argentina and Uruguay.

Frequently asked questions
How to improve the accuracy of your Spanish transcripts?
Start by improving the quality of the Spanish VOB 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 Spanish VOB file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Spanish VOB file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from VOB, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Spanish with Sonix:
Why is my DVD split into several VOB files?
The DVD-Video specification limits each VOB segment to 1 GB, so longer titles are stored as sequential files (VTS_01_1.VOB, VTS_01_2.VOB, and so on) inside the VIDEO_TS folder. You can transcribe each segment separately or join them into a single file first for one continuous transcript.
My VOB has multiple audio tracks — which one gets transcribed?
VOB files can multiplex several audio streams, such as different languages or a commentary track. Transcription uses one audio stream at a time, so if you need a track other than the default, extract or remux that stream before uploading.
Does Spanish transcription handle Latin American accents?
Yes. Sonix transcribes Spanish audio from across Latin America — including Mexican, Caribbean, Andean, and Rioplatense speech — as well as Peninsular Spanish from Spain, and the in-browser editor lets you correct any regional wording afterward.
Can Sonix transcribe Castilian Spanish from Spain?
Yes. Spanish from Spain, including the Castilian distinción (the "th" sound for c and z), is supported under the same Spanish language option — upload your file, transcribe, then edit and export.
Can I turn a Spanish transcript into subtitles?
Yes. After transcribing and editing a Spanish file, you can export subtitle formats such as SRT and VTT with ñ and accented characters preserved.
