Understanding Spanish FLAC 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 FLAC 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 FLAC file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Spanish FLAC file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from FLAC, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Spanish with Sonix:
Do I need to convert FLAC to MP3 before transcribing?
No. FLAC files can be uploaded and transcribed directly, and skipping the MP3 conversion avoids an unnecessary lossy re-encode of your audio.
Why won't my FLAC file play in iTunes or Apple Music?
Apple's media apps do not natively support FLAC; Apple uses its own lossless codec, ALAC. You can play FLAC on Apple devices through the Files app or a third-party player, or convert the file to ALAC or AAC for library use.
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.
