The role is an Audio Engineer (Speech / TTS Audio Specialist) for French, working at a company that focuses on preparing high-quality audio datasets for machine learning systems. The company specializes in speech and text-to-speech (TTS) applications, ensuring clarity, consistency, and technical compliance across large volumes of French speech data. The main day-to-day responsibilities include editing and processing French voice recordings for use in TTS and speech AI systems. This involves performing audio cleanup tasks such as silence trimming, breath reduction, de-clicking, de-essing, and noise reduction. Additionally, the role requires conducting detailed quality assurance checks for issues like clipping, distortion, background noise, and loudness consistency. The audio must meet strict technical specifications for machine learning training pipelines. The engineer will also evaluate recordings for French pronunciation accuracy, naturalness, and fluency, and work with large batches of recordings while maintaining consistency and throughput. Collaboration with teams working on French speech datasets, voice talent recordings, and model training workflows is also part of the job. To qualify, candidates must be native or near-native French speakers with a strong listening intuition for French speech nuances. Experience in editing speech or voice recordings, not just music production, is essential. A strong understanding of speech audio quality standards and common issues in recorded dialogue is required. Hands-on experience with tools like iZotope RX, Pro Tools, or similar audio restoration software is necessary. The ability to identify and fix artifacts, inconsistencies, and technical defects in audio, as well as experience working with high-volume audio datasets or structured workflows, is crucial. Nice-to-have skills include experience working with TTS vendors or platforms, prior involvement in speech ML, voice AI, or dataset creation/annotation workflows, and familiarity with audio QA pipelines, labeling, or evaluation processes. Experience directing or editing French voice talent recordings is also beneficial. The ideal candidate is detail-oriented with strong critical listening skills in French, comfortable with repetitive, high-precision tasks at scale, and able to balance speed and quality in production environments. The role involves working with the nuances of human French speech versus synthetic voice requirements.
