What this actually is

You record voice samples following scripts, evaluate AI-generated audio for quality, and provide expert feedback used to train speech models. Often paid by the minute or hour of recording. The platform title (Spanish (Spain) Professional Voice Actor) reflects the rate band and the expertise required, not the day-to-day work.

Original posting from Mercor

Mercor is hiring Castilian Spanish Voice Actors to work directly with a leading AI lab, improving their model's ability to handle and produce audio data.

Professional experience in Voice Acting is greatly preferred but not required. We welcome people with speaking and audio experience through Music, Television, Podcasts, Twitch Streaming, Comedy, YouTube, Radio, or other related fields.

You must be a native speaker of Castilian (European) Spanish, born and raised in Spain. This role is distinct from our Mexican Spanish listing - please apply to the one matching your native variety.

You also need to be a proficient English speaker to ensure proper communication during the project.

Project logistics

  • Participants are paid $250 USD per finished hour, based on the length of submitted audio.
  • You'll need to commit between 2-10 hours per week.
  • Rolling start - onboarding begins once your contract is accepted and ID verification clears.
  • You will need to be available for a kickoff call.

Requirements

  • Ability to speak in a "customer service" voice - neutral to upbeat tone, clear enunciation, consistent pacing.
  • Close attention to punctuation, commas and dashes. It is very important that you record transcripts exactly as written, or edit them to reflect natural pacing.
  • A professional audio recording setup: a home studio with a professional-grade microphone, soundproofing, an audio interface, a pop filter, and editing software for post-production.
  • Submissions must be WAV, 44.1 kHz, mono, with under one second of silence at the start and end, and no audible breathing.
