Understanding Spanish AIFF 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 AIFF 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 AIFF file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Spanish AIFF file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from AIFF, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Spanish with Sonix:
Why are my AIFF files so large?
AIFF stores uncompressed PCM audio, which works out to roughly 10 MB per minute at CD quality. Converting to a compressed format like MP3 or a lossless codec like FLAC reduces the size if storage or upload time is a concern.
Do AIFF files play on Windows?
Most modern Windows media players and audio editors can open AIFF files, although WAV is the more common uncompressed format on that platform. If a specific program rejects the file, converting it to WAV preserves the audio exactly.
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.
