Understanding Spanish transcription

Who transcribes Spanish content?

Broadcast and digital newsrooms across Spain and Latin America, U.S. courts and law firms handling Spanish-language testimony, and market researchers running Spanish focus groups all transcribe Spanish audio regularly. Academic researchers, podcasters, and healthcare and government teams serving Spanish-speaking communities rely on it as well.

Spanish dialects and accents

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.

Where Spanish is spoken

Spanish is spoken in Argentina, Bolivia, Chile, Colombia, Costa Rica, Cuba, Dominican Republic, Ecuador, El Salvador, Equatorial Guinea, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Spain, Uruguay, and Venezuela.

Spanish transcription FAQ

Frequently asked questions about
Spanish burn-in subtitles

What's the difference between burn-in and soft subtitles?

Burn-in (hardcoded) subtitles are permanently embedded in the video pixels and cannot be turned off. Soft subtitles (SRT/VTT) are separate files that viewers can toggle on/off. Burn-in is ideal for social media where caption support is inconsistent.

Can I customize the subtitle appearance?

Yes! Sonix offers extensive styling options including font family, size, color, background color, opacity, and position (top, middle, bottom). Preview your style in real-time before rendering.

Will burn-in subtitles reduce video quality?

Sonix preserves your original video quality during the burn-in process. We use high-quality rendering to ensure subtitles look crisp and professional without degrading your footage.

How long does burn-in processing take?

Processing time depends on video length and resolution. A typical 10-minute 1080p video takes about 5-10 minutes to render. You'll receive an email notification when your video is ready.

What video format does burn-in export?

Sonix exports burned-in videos as MP4 files with H.264 encoding—the most universally compatible video format. Your video will play on virtually any device or platform.

Can I edit subtitles after burn-in?

No. Once subtitles are burned in, they're permanent. We recommend thoroughly reviewing and editing your transcript in the Sonix editor before rendering. You can always create a new burn-in version if needed.

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.
