• Communication: fluent English skills for instruction following and reporting
• Soft skills: high attention to detail; backgrounds in linguistics or translation are a plus
• Technical setup: access to a quiet environment and good quality headphones/ speakers
• A PayPal account to receive payment from our clients

What you’ll be doing in the role

• Side‑by‑side evaluation: comparing text and voice snippets to assess quality and authenticity
• Naturalness assessment: listening to AI‑generated audio and rating how natural the voice sounds
