About this role
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 Spain-based voice actors with native Castilian/Peninsular Spanish accents to contribute high-quality voice recordings for training and evaluating cutting-edge speech models. This role is open to professional voice actors as well as people with customer-support, call-center, or other customer-experience (CX) backgrounds — and to newcomers with a naturally clear, expressive voice and a good recording setup. Prior voice-acting experience is a plus but not required.
This is an ongoing opening — we onboard new voices on a rolling basis, so applications are always welcome. The engagement itself is a single recording session of approximately 4 hours. A second session of similar length may follow depending on the client's needs, though this isn't guaranteed.
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

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

- Ability to follow scripts precisely while maintaining natural delivery
- Availability for a single ~4-hour recording session, with the possibility of a further session of similar length later on
- \[IMP\]: 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.
