Spanish (Spain) Audio Transcript Editor – Castilian Specialists

About the Role

What if your sharp ear and deep knowledge of Castilian Spanish could directly influence how AI understands spoken language? We're looking for meticulous transcript editors in Buenos Aires — especially those with strong familiarity with Spain's Spanish dialect — to review, correct, and refine audio transcripts that will train next-generation AI speech systems.

This is focused, precision-driven work for people who genuinely care about linguistic accuracy. If you can hear the difference between a voiced and unvoiced consonant, notice a misplaced accent, or catch a timestamp that's off by a beat, you'll thrive in this role.

This is a fully remote, flexible contract role. No prior AI experience needed — just native or near-native command of Castilian Spanish, strong listening skills, and a commitment to doing the work right.

What You'll Do

• Listen to Castilian Spanish audio recordings and compare them against existing transcripts, correcting errors at the word level
• Fix misheard words, misspellings, punctuation errors, and formatting inconsistencies
• Verify and adjust word-level timestamps to ensure precise synchronisation with the audio
• Apply detailed style and formatting guidelines consistently across all tasks
• Flag unclear audio, overlapping speech, or segments that require additional review
• Maintain high accuracy and quality standards across large volumes of transcript data
• Work independently and asynchronously — fully on your own schedule

Who You Are

• Native or near-native Castilian Spanish speaker — deep familiarity with Spain's pronunciation, vocabulary, and linguistic nuances is essential
• Excellent listening skills with the ability to accurately distinguish words in varied audio conditions
• Highly detail-oriented with a methodical, patient approach to repetitive precision work
• Comfortable working with exact timing and word-level accuracy
• Able to follow and consistently apply detailed style guides and formatting rules
• Strong written communication skills in Spanish
• Self-motivated and reliable when working independently
• No prior AI or tech experience required

Nice to Have

• Experience as a transcriptionist, court reporter, or stenographer
• Background in subtitling, closed-captioning, or subtitle editing
• Linguistics training or academic background in Spanish — particularly Iberian Spanish phonology or grammar
• Prior work with annotation platforms, data labeling tools, or transcript editing software
• Familiarity with phonetics, speech processing, or audio analysis
• Experience following detailed editorial or formatting style guides
