I will perform chinese asr audio QA, tts validation, and phonetic alignment
About this Gig
Are you developing Chinese ASR or TTS speech models and looking for reliable, high-precision human data validation?
I am a native Mandarin AI Data Specialist with 3+ years of experience in audio annotation, speech-to-text QA, and phoneme verification for generative AI models. Rather than simple transcription, I focus on precise linguistic QA to help AI teams improve model accuracy and remove training artifacts.
What I offer in this Gig:
- ASR Transcript QA & Correction: Verifying machine transcriptions against human audio with high precision.
- TTS Quality Control & Phoneme Alignment: Checking boundary markers, tone accuracy, naturalness, and robotic artifacts.
- Dialect & Mixed Speech Verification: Handling Standard Mandarin, Northern Chinese dialects, and Chinese-English mixed audio.
- Detailed Error Classification: Categorizing speech issues into tail truncation, alignment shift, pitch error, or background noise.
Tools & Formats:
Experienced with Argos, CVAT, web inspection tools, JSON, CSV, and SRT file structures.
I adhere strictly to project guidelines and strict data confidentiality. Contact me today or select a package to get started!
Language:
Chinese (simplified)
Delivery style preference
Please inform the freelancer of any preferences or concerns regarding the use of AI tools in the completion and/or delivery of your order.
FAQ
What formats do you accept for audio and annotation files?
I accept standard audio formats (WAV, MP3, FLAC, M4A) and annotation formats including CSV, JSON, XLS, TXT, and SRT.
Do you handle multi-speaker or noisy audio?
Yes! Basic/Standard packages cover clear or mild background noise. For low-quality, overlapping, or chaotic multi-speaker audio, please select the Premium package or contact me for a custom quote.
How do you handle non-disclosure and data privacy?
Data privacy is paramount. I strictly adhere to NDA standards, never share customer data, and store files on secure, encrypted drives.
Can you handle custom tool environments or project guidelines?
Absolutely. I am experienced with web-based trace log platforms, CVAT, Argos, and custom internal tools. Just share your guidelines and workflow access after placing the order.
