You will get AI Voice & TTS Quality Check
Project details
I review German-language audio files and identify errors, unnatural phrasing, and quality issues affecting listener experience or AI training accuracy.
As a native German speaker from Lower Saxony — the regional benchmark for Standard German (Hochdeutsch) — I bring a calibrated ear for deviation from broadcast-standard pronunciation, the variety used in most German TTS model development.
What I check:
Mispronounced or incorrectly read words
Words added, missed, or substituted from script
Unnatural intonation or stress patterns
Awkward or incorrect pauses
Dialect suitability for your AI model and deployment context
What you receive:
Timestamped error log with severity ratings and correction notes — ready for your data pipeline or voice team.
Why dialect matters:
Strong Bavarian, Saxon, or Swiss German can cause phoneme mismatches in your model even with a fluent speaker. I flag these risks before they become training data problems.
Ideal for: AI/TTS companies, voice app developers, language data firms, and dataset curators needing reliable native German QA.
