Job Title: Speech Subject Matter Experts
Job Duration: Contract until March 31, 2027, with the possibility of extension
We’re seeking Speech Subject Matter Experts with exceptional critical-listening skills to help evaluate and refine datasets for next-generation voice AI. Your trained ear will help set the standard for natural, emotionally authentic speech and high-quality audio.
What you’ll do
- Develop and maintain annotation standards for vocal inflection, emotion, and audio quality.
- Audit speech annotations and compare model outputs to identify subtle differences in performance.
- Assess pitch, intent, cadence, emotional nuance, and adherence to prompts.
- Provide clean voice recordings for calibration and testing when needed.
What we’re looking for
- Demonstrated 90%+ accuracy in blind tests that assess subtle audio differences
- Reference-grade headphones, such as Sennheiser HD 600, Beyerdynamic DT 770 Pro, or Sony MDR-7506, paired with a dedicated DAC or audio interface. Consumer headphones and earbuds do not meet this requirement.
- Background in audio engineering or mastering, voice acting, speech-language pathology, music production, radio, or sound design.
- Experience with data annotation or RLHF evaluation workflows.
