We are sharing a specialised part-time consulting opportunity for experienced audio engineers with strong expertise in speech editing, voice-recording quality assurance, and text-to-speech (TTS) audio workflows, specifically for French-language content.
This role focuses on preparing and evaluating high-quality French speech audio for machine-learning and voice-AI applications. Selected professionals will edit, clean, and quality-check large volumes of voice recordings while ensuring consistency, naturalness, pronunciation accuracy, and compliance with technical audio specifications.
Key Responsibilities
Speech Audio Editing & Restoration
- Edit and process French voice recordings for speech and TTS applications
- Perform silence trimming, breath reduction or removal, de-clicking, de-essing, and noise reduction
- Identify and correct clipping, distortion, background noise, and unwanted audio artifacts
- Balance loudness and recording levels across large batches of speech audio
- Maintain consistent audio quality across structured production workflows
French Speech Quality Evaluation
- Evaluate French recordings for pronunciation accuracy, fluency, and naturalness
- Identify unnatural delivery, articulation issues, or inconsistencies in spoken French
- Assess speech quality using native or near-native listening judgement
- Distinguish between acceptable human speech variation and issues that may affect synthetic-voice training
- Provide precise quality feedback on recordings that require correction or rework
TTS & Voice AI Audio Quality
- Prepare audio that meets technical requirements for TTS and speech-AI training pipelines
- Review recordings for consistency with dataset and model-training specifications
- Assess audio quality across voice-talent recordings and structured speech datasets
- Support quality-control workflows designed for large-scale machine-learning datasets
- Identify technical or performance issues that could reduce the usefulness of training audio
Audio QA & Dataset Workflows
- Conduct systematic quality-assurance reviews across high-volume audio batches
- Apply consistent evaluation standards throughout repetitive production workflows
- Flag technical defects, inconsistencies, and recording-quality issues
- Maintain accuracy and throughput while working across large datasets
- Contribute to reliable audio QA, labelling, and evaluation processes
Ideal Profile
- Native or near-native French fluency with strong listening intuition for pronunciation, rhythm, and natural speech
- Professional experience editing speech, dialogue, voice-over, or other voice recordings
- Strong understanding of speech-audio quality standards and common recording defects
- Hands-on experience with tools such as iZotope RX, Pro Tools, or comparable audio-editing and restoration software
- Ability to identify and correct artifacts, inconsistencies, noise, clipping, and other technical audio issues
- Strong critical-listening skills and attention to fine audio detail
- Experience working with high-volume audio datasets or structured production workflows
- Experience with TTS, speech ML, voice AI, dataset creation, or audio annotation is highly valued
- Familiarity with audio QA pipelines, labelling, or evaluation processes is advantageous
- Experience editing or directing French voice-talent recordings is particularly relevant
- Ability to balance production speed with consistent quality across repetitive, high-precision work
Engagement Details
- Fully remote independent contractor engagement
- Flexible scheduling based on project requirements
- Compensation: $40–$45/hour
- Projects may be extended, shortened, or concluded based on project needs and performance
- Work must be completed without using confidential or proprietary information belonging to any employer, client, institution, or other third party
- H1-B and STEM OPT support is unavailable for this engagement
- Strong contributors may be considered for additional speech-audio and voice-AI projects
