The job description
About the Role
We're looking for US-based native and heritage speakers of Castilian Spanish (Peninsular/Spain) to help train and evaluate cutting-edge AI speech models. Your ear for the authentic sounds, rhythms, and nuances of European Spanish will directly shape how the next generation of AI understands and produces language.
This is a rare opportunity to turn your deep linguistic intuition into meaningful, well-compensated remote work — no prior AI experience required.
What You'll Do
- Listen and Evaluate: Assess AI-generated audio samples for phonetic accuracy, naturalness, and adherence to authentic Castilian Spanish patterns
- Transcribe and Annotate: Label diverse audio samples with precision, capturing the distinct sounds and structures of Peninsular Spanish
- Catch Model Errors: Identify and flag hallucinations, phonetic mistakes, or Latin American dialect bias that slips into model outputs
- Analyze Prosody and Acoustics: Evaluate model performance on cadence, the apical "s," and the overall rhythm of European Spanish speech
- Provide Expert Feedback: Write clear, structured English justifications explaining why audio outputs meet or fall short of Castilian standards
- Ensure Cultural Authenticity: Validate that AI outputs reflect genuine, lived Castilian Spanish — from modern slang to formal registers
Who You Are
- Native or heritage Castilian Spanish speaker with deep, intuitive command of Peninsular Spanish as spoken in Spain
- Phonetically attuned — you can instantly recognize distinción (the "th" sound for z and ce/ci), vosotros usage, and leísmo/laísmo patterns
- Detail-oriented and analytical — you notice what others miss and can articulate why something sounds off
- Strong English writer — able to produce clear, professional technical feedback in English
- Comfortable with technology — familiar with audio tools, data annotation platforms, or willing to learn quickly
Nice to Have
- Background in linguistics, phonetics, translation, or language instruction
- Experience with audio editing or transcription tools
- Familiarity with AI training workflows or data labeling platforms
Why This Role
- Flexible, fully remote — work on your own schedule from anywhere
- Meaningful impact — your expertise directly improves how AI systems represent and respect linguistic diversity
- Specialized work — your Castilian Spanish knowledge is genuinely rare and valued here
- Engaging variety — no two audio samples are the same; this is intellectually stimulating work
- Potential for ongoing collaboration and contract extension based on performance
