Role summary

As an AI Tutor specialized in multilingual audio capabilities, you will train and refine Grok to excel in voice interactions, speech recognition, and auditory experiences across diverse languages, accents, and cultural contexts. The role focuses on curating and annotating high-quality audio data to improve spoken interactions, speech processing, and handling of multilingual audio nuances.

Responsibilities

• 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.
• Support delivery of high-quality curated audio data that ensures clear, natural spoken output and accurate representation of linguistic and prosodic details (intonation, rhythm, accent) and professional audio standards.
• Collaborate with technical staff to develop tasks that improve the AI's ability to handle speech modulation, accent variation, noise in real-world recordings, and multilingual audio processing.
• Work with technical staff to improve annotation tools for efficient audio workflows.

Requirements

Basic qualifications

• Native proficiency in Portuguese with exposure to diverse accents, dialects, or regional variations.
• Proficiency in English (minimum B2) with clear, natural vocal delivery and pronunciation suitable for audio recording.
• Strong auditory perception to identify nuances in speech, accents, pronunciation, intonation, and audio quality across languages.
• Demonstrated ability to handle multilingual audio content, including evaluating speech accuracy, cultural vocal expressions, and contextual interpretation in spoken form.
• Demonstrated ability to transcribe audio with high accuracy across accents and varying audio quality.

• Strong command of advanced transcription and annotation practices, including handling disfluencies, accents, and prosodic features (intonation, stress, rhythm, emotion) with high consistency and accuracy.
• Background in linguistics (phonetics, phonology, sociolinguistics), speech sciences, cognitive science, or equivalent practical experience, with demonstrated ability to analyze accent variation and multilingual speech patterns.
• Experience working with speech/audio datasets, annotation workflows, or AI training data, including knowledge/experience with training voice models and understanding how data quality impacts model performance.
• Professional experience in voice work (voice acting, podcasting, etc.) or audio production demonstrating attention to clarity and recording quality.
• Portfolio strongly preferred for advanced candidates (voice samples, annotated transcripts, or audio-related work).

Location and other expectations

• Roles may be full-time, part-time, or contractor positions depending on needs and candidate fit.
