About the role

We are hiring an Audio QA Lead to support the development of high-quality training datasets for next-generation voice AI models. In this role, you will work hands-on to improve the quality, consistency, and usability of speech datasets across applications such as text-to-speech, transcription, speech-to-speech, ASR, and conversational voice systems. Your work will directly influence how data is collected, reviewed, and delivered for real-world model training. You will work across three core areas: defining and applying audio quality standards, recording high-quality speech on demand, and performing annotation and QA across speech datasets. This is not a generic audio production role. The work focuses on making audio usable for model training and requires a strong understanding of how data quality impacts model. This is a part-time contractor role that can turn into full-time role.

Develop, refine, and apply audio quality guidelines for speech and voice datasets.
Review audio files against technical, linguistic, and task-specific standards, making clear approval, rejection, or revision decisions.
Identify audio and annotation issues such as background noise, clipping, distortion, plosives, echo,...
