Izotope Jobs (NOW HIRING)

About the job Remote | Audio Engineer (French Speech & TTS) - Up to $45/hour
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

• 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

• 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

• 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

• 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

• 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
