Specialised Consulting Opportunity for Experienced Audio Engineers

We are sharing a specialised consulting opportunity for experienced audio engineers with strong expertise editing and quality-checking German-language speech recordings for text-to-speech, speech AI, and machine learning applications.
This role focuses on preparing high-quality German speech datasets for advanced AI systems. Selected professionals will edit and restore voice recordings, perform detailed technical quality assurance, evaluate pronunciation and naturalness, and ensure large volumes of audio meet consistent production and machine learning specifications.
Key Responsibilities

Speech Audio Editing
Edit and process German-language voice recordings for speech and TTS applications
Perform silence trimming, breath reduction or removal, de-clicking, de-essing, and noise reduction
Correct technical defects while preserving natural speech characteristics
Prepare clean, consistent recordings suitable for machine learning pipelines
Work efficiently across large batches of speech audio
Audio Quality Assurance
Review recordings for clipping, distortion, background noise, and unwanted artefacts
Assess loudness consistency and level balance across recordings
Identify recording inconsistencies and technical defects
Ensure audio conforms to defined technical and production specifications
Maintain consistent quality standards across high-volume datasets
German Speech Evaluation
Evaluate pronunciation, fluency, naturalness, and overall speech quality in German
Identify unnatural pronunciation, articulation, pacing, or delivery
Apply native or near-native listening judgment to German speech nuances
Distinguish linguistic or performance issues from technical audio defects
Assess recordings for suitability within speech and TTS training workflows
Dataset & Production Workflow
Work with structured speech datasets and large recording batches
Maintain accuracy and throughput across repetitive, high-precision tasks
Collaborate with teams working on voice talent recordings and speech-model training
Follow established audio QA, file-management, and evaluation processes
Provide clear technical feedback on recordings requiring correction or replacement
Ideal Profile
Strong candidates may have:
Native or near-native German fluency
Professional experience editing speech, dialogue, narration, or voice recordings

Practical knowledge of speech audio quality standards
Experience identifying and correcting noise, clipping, distortion, clicks, sibilance, and related defects
Hands-on experience with professional audio restoration or editing software
Experience working with high-volume audio datasets or structured production workflows
Strong attention to detail and ability to maintain consistent quality at scale
Educational Background
Training in audio engineering, sound engineering, audio production, broadcast production, or a related discipline may be helpful
Equivalent professional experience in speech editing, dialogue production, or audio post-production may also be considered
Practical speech-audio editing expertise is particularly valuable for this engagement
Nice to Have
Experience with iZotope RX, Pro Tools, or comparable audio restoration software
Previous work with text-to-speech platforms or vendors
Experience with speech ML, voice AI, or synthetic speech projects
Familiarity with audio annotation or QA pipelines
Experience preparing datasets for machine learning applications
Background directing or editing German voice talent
Knowledge of dialogue restoration and speech-specific post-production
Experience assessing differences between natural and synthetic speech
