What the work involves

You receive transcripts in Castilian Spanish and record them in a neutral-to-upbeat "customer service" register: clear enunciation, steady pacing, no drifting into either flat reading or theatrical performance. The transcripts are to be read exactly as written — punctuation, commas and dashes carry timing information the lab is training against — or, where a script reads unnaturally aloud, edited so the pacing is natural and the edit is recorded faithfully. Some batches will involve varied emotional colour or conversational delivery; most will be steady, repetitive, and technically exacting.

Delivery specs are non-negotiable and mechanical: WAV, 44.1 kHz, mono, under one second of silence at head and tail, no audible breaths, no room tone, no plosives. Files that fail spec come back to you. That means your real throughput depends as much on your editing discipline as on your voice.

What the platform screens for

  • Native Castilian Spanish, born and raised in Spain. This is a separate listing from Mexican Spanish; applying to the wrong variety wastes the screen.
  • A genuinely professional home setup — professional-grade microphone, audio interface, treated or soundproofed space, pop filter, and DAW/editing software you can actually operate. Screeners ask for specific model names and will notice vagueness.
  • Evidence of recorded speaking work, which does not have to be commercial voice acting. Podcasting, radio, streaming, music, YouTube, comedy and television all count if you can point to audio.
  • Working English, since project communication, briefs and the kickoff call are in English.

Logistics

Fully remote and largely async, with a rolling start: onboarding begins once your contract is accepted and ID verification clears, and you must be available for a live kickoff call. Expect 2–10 hours per week. Pay is quoted at $250 USD per finished hour of accepted audio — a finished hour means the duration of usable submitted audio, not the wall-clock time you spend recording and editing, so your effective hourly rate depends on your take-one accuracy and post-production speed. The broader observed band across similar Mercor audio work runs from roughly $35/hr upward; rates are as observed, not guaranteed.
