Job Description
About the Role
As a Danish Speech & Audio AI Specialist in our Global AI Community, you evaluate and validate speech AI systems - ensuring machine-generated voices sound natural, speech recognition captures intent accurately, and voice AI models learn from high-quality datasets. Your work directly impacts millions of users' voice-based AI experiences.
What You'll Do
Audio Evaluation & Quality Assessment
- Evaluate AI-generated speech (TTS) for naturalness, pronunciation, rhythm, tone, and emotion
- Identify transcription errors, pronunciation issues, and linguistic nuances in speech recognition (ASR) outputs
- Conduct audio quality checks (loudness, noise, clipping, distortion, compliance)
- Analyze audio using waveform and spectrogram tools to identify quality issues
- Provide structured feedback for model improvement
Audio Editing & Technical Proficiency
- Perform professional audio editing (segmentation, trimming, noise reduction, enhancement)
- Apply audio restoration techniques to optimize speech samples
- Prepare and validate speech content for training pipelines
Speech Linguistics & Dataset Validation
- Apply phonetics and linguistics expertise to identify speech variations across accents and languages
- Review voice recordings for clarity, consistency, and technical quality
- Support creation and validation of high-quality speech datasets
- Perform audio annotation and labeling for dataset integrity
Voice AI Project Support
- Support TTS, ASR, voice similarity, voice generation, and conversational AI evaluation projects
- Contribute to quality assurance workflows for voice technology projects
- Document findings to inform model improvement
