Job description

As a Korean Linguist in our Global AI Community, you evaluate and validate speech AI systems from a linguistic perspective -ensuring machine-generated voices communicate with natural language flow and prosody, speech recognition captures intent with linguistic accuracy, and voice AI models are trained on linguistically sound datasets. Your work directly impacts millions of users' voice-based AI experiences by maintaining the highest standards of linguistic quality and cultural authenticity.

What You'll Do

Linguistic Analysis & Language Quality Assessment

• Analyze AI-generated speech (TTS) for naturalness of language patterns, pronunciation accuracy, prosodic rhythm, intonation, and emotional register from a linguistic perspective
• Identify transcription errors, phonological and morphological issues, and linguistic nuances in speech recognition (ASR) outputs
• Conduct linguistic quality evaluation of speech output including assessment of grammar, semantics, pragmatics, and discourse coherence
• Apply phonetic and phonological analysis to identify pronunciation variations, dialectal features, and language-specific patterns
• Provide structured linguistic feedback for model improvement

Language Variation & Dialectological Analysis

• Apply expertise in phonetics, phonology, morphology, and syntax to identify speech variations across Korean dialects and accents
• Analyze prosodic features including stress patterns, intonation contours, and rhythm across different speech varieties
• Document regional and sociolinguistic variations in speech patterns to inform dataset diversity
• Evaluate linguistic consistency and naturalness across different speaker profiles and contexts

Speech Dataset Validation & Annotation

• Review voice recordings for linguistic clarity, consistency, and technical quality
• Apply linguistic expertise to support creation and validation of high-quality speech datasets with attention to language structure and variation
• Perform detailed linguistic annotation and labeling for dataset integrity (phonetic transcription, prosodic markup, morphological tagging where applicable)
• Assess dataset diversity and representativeness from a linguistic perspective
• Identify and document linguistic patterns that improve ASR and TTS model performance

Voice AI Project Support

• Support TTS, ASR, voice similarity, voice generation, and conversational AI evaluation projects with linguistic expertise
• Provide linguistic quality assurance for voice technology projects focused on naturalness and semantic/pragmatic accuracy
• Document linguistic findings to inform model improvement and contribute to research insights
• Assess how linguistic features impact user perception and model performance
