Job description

Mercor is partnering with a leading AI research lab to build next-generation text-to-speech (TTS) systems capable of producing natural, expressive, and human-like voices. We are seeking Mexico-based voice actors with native Mexican Spanish accents to contribute high-quality voice recordings for training and evaluating cutting-edge speech models. This role is open to both experienced voice professionals and newcomers with a naturally clear, expressive voice and a good recording setup — prior voice-acting experience is a plus but not required.

Your voice recordings will be used exclusively for the client's internal CX AI Agent. They will not be sold, licensed, or reused for any other product, dataset, or purpose.

Key Responsibilities

• Record high-quality voice samples across diverse scripts (conversational, narrative, instructional, etc.)

• Deliver clear, natural, and expressive speech with strong control over tone, pacing, and pronunciation

• Maintain consistency in voice, accent, and delivery across recording sessions

• Follow detailed recording guidelines (environment, microphone setup, file formatting)

• Perform multiple takes with variation in emotion, emphasis, and style when required

Requirements

• Native Mexican Spanish speaker currently based in Mexico

• A clear, natural, and expressive voice (prior voice acting, narration, or broadcast experience is a plus, not required)

• Access to a professional or near-professional recording setup (quality microphone, quiet environment, pop filter, etc.)

• Strong command of intonation, diction, and emotional range

• Ability to follow scripts precisely while maintaining natural delivery

• Reliable availability for 5-10 hours per week over the project duration

• [IMP]: Your voice may be cloned for the client's CX AI Agent so please only apply if you are okay with voice cloning. Your recordings will not be sold or reused outside of this specific use case.

Preferred Qualifications

• Experience recording for TTS, audiobooks, IVR systems, or AI voice datasets

• Familiarity with audio editing tools (e.g., Audacity, Adobe Audition, Reaper)

• Ability to deliver multiple vocal styles (e.g., conversational, corporate, energetic, calm)
