AI Tutor - Czech

xAI xAI · AI Frontier · United States · Remote · Human Data

The role focuses on training and refining AI models (Grok) for multilingual audio capabilities, including voice interactions, speech recognition, and auditory experiences. Responsibilities involve curating and annotating high-quality audio data, translating and localizing text, and collaborating with technical staff to improve AI's handling of multilingual audio nuances and annotation tools. The core of the work is data preparation and annotation for AI model training.

What you'd actually do

  1. Use proprietary software to provide labels, annotations, recordings, and inputs on projects involving multilingual audio clips, voice recordings, speech samples, and auditory elements in various languages.
  2. Translate and localize text strings (UI copy, prompts, responses, and other written content) from English into Czech, ensuring linguistic accuracy, natural phrasing, and cultural appropriateness.
  3. Support the delivery of high-quality curated audio data that ensures clear, natural spoken output, accurate representation of linguistic and prosodic details (such as intonation, rhythm, and accent), and professional audio standards.
  4. Collaborate with technical staff to develop tasks that improve AI's ability to handle speech modulation, accent variation, noise in real-world recordings, and multilingual audio processing.
  5. Work with technical staff to improve annotation tools for efficient audio workflows.
