Who Uses Musely Spanish Transcription
Turn weekly Spanish podcast episodes into blog posts
I record a Mexican Spanish podcast and used to pay a transcriber $60 per episode. Musely handles every diacritic correctly and keeps the Mexican flavor — it doesn't try to flatten my guests into neutral Spanish. The Clean Read style saves me an hour of editing per episode.
Transcribe field interviews across Latin America
I cover stories across Mexico, Colombia, and Argentina. Musely handles all three dialects without me having to correct 'vos' to 'tú' afterwards. The Interview Q&A preset with speaker labels gives me a clean transcript I can quote from directly, with correct inverted punctuation throughout.
Process Spanish user interviews for qualitative research
I run user research studies in Mexico City and Buenos Aires. The Verbatim preset preserves every hesitation and filler — critical for qualitative coding. Musely's custom vocabulary field handles our product's internal names and UI terms with correct spelling.
Add accurate Spanish subtitles to every upload
The Subtitle-Ready SRT preset gives me YouTube-ready captions with correct Spanish punctuation. Every ¿ and ¡ in the right place, every accent preserved. I used to spend 2 hours cleaning up auto-generated subtitles. Now it takes 10 minutes.
Produce certified-quality Spanish deposition transcripts
Verbatim mode with speaker labels and timestamps gives me word-for-word Spanish transcripts with overlapping speech marked as [cruce de voces]. The custom vocabulary field handles legal terminology and proper names. I deliver transcripts in half the time it used to take.
Build bilingual subtitles and training materials
Bilingual mode outputs Spanish first, English second — exactly the format my clients want for training videos. The translation preserves dialect context instead of flattening it. I can deliver finished bilingual subtitle files instead of raw transcripts.

What Spanish Creators Say
4.8/5 based on 3,260 reviews
“Finally a Spanish transcription tool that doesn't turn my Argentine guests into neutral Spanish. Voseo stays intact, 'che' stays in, inverted punctuation is always correct. I run a weekly podcast and saved about 4 hours per week since switching.”
“I transcribe user interviews for a UX research agency across Mexico and Spain. Musely handles both Castilian vosotros and Mexican ustedes without me having to correct either. The Verbatim preset captures hesitations we need for qualitative analysis.”
“The Subtitle-Ready preset outputs SRT files with every diacritic and inverted mark in place. I used to spend 2 hours cleaning up auto-captions for my Spanish YouTube channel. Now it's 10 minutes of review and upload. The bilingual mode is also useful for my English-speaking audience.”

It preserves dialect-specific vocabulary and register, applies correct diacritics and inverted punctuation, and offers 4 transcript styles.
Otter.ai is English-optimized with weaker Spanish accuracy. Rev offers 95% accuracy via human review but costs $1.50/minute and ships neutral Spanish.

Yes. When you select the Rioplatense dialect or leave Auto-detect on, Musely preserves voseo ('vos tenés', 'vos podés') exactly as spoken. It does not normalize to 'tú tienes'. Regional vocabulary like 'che', 'boludo', 'quilombo' stays intact. The same preservation applies to vosotros in Castilian Spanish and ustedes in Latin American Spanish.
Yes. The Caribbean dialect setting tunes the ASR engine for fast-paced speech and dropped 's' sounds common in Cuban, Puerto Rican, and Dominican Spanish. Musely reconstructs the dropped 's' in the written transcript so 'má' becomes 'más' and 'ehtá' becomes 'está', while preserving regional vocabulary and idioms.
Musely offers 4 Spanish transcript styles: Clean Read (fillers removed for podcasts), Verbatim (every 'eh' and 'este' preserved for legal/research), Interview Q&A (labeled questions and answers for journalism), and Subtitle-Ready (SRT with 42-char lines for video). All styles apply correct diacritics and inverted punctuation.
Yes. Set Output Language to English (or any of 48 other languages) and Musely translates automatically. Toggle 'Also Show Original Text' on for bilingual output with Spanish first, English second. This works for any transcript style including Subtitle-Ready SRT for bilingual video captions.
Musely's post-processing layer applies Spanish orthography rules on top of the Seed-ASR 2.0 output. It resolves common ambiguities — 'si' vs 'sí', 'mas' vs 'más', 'esta' vs 'está' — based on sentence context, and enforces inverted opening marks (¿, ¡) for all questions and exclamations. The custom vocabulary field handles proper names with correct diacritics.
