Data Annotator (Speech - Vietnamese)

About the Role

Cake by VPBank is one of Vietnam's fastest-growing digital banks — 6M+ users and on a mission to become the NextGen AI Bank. We believe generative AI will redefine banking: smarter, faster, and more human. We are investing in AI-powered voice and speech features for our digital banking products. Behind every great speech model is high-quality, carefully labeled data — and that's where you come in.

As a Data Annotator (Speech) , you'll listen to Vietnamese audio recordings and create accurate transcriptions and labels that our AI team uses to build and evaluate speech-recognition models. It's detail-driven work with real impact: what you produce directly shapes how well our voice technology understands real customers across every region of Vietnam.

This is a fixed-term labeling engagement of 2–3 months.

Key Responsibilities

• Apply audio attribute labels such as: regional accent, speaker gender.
• Follow the team's annotation guidelines and conventions closely to keep labeling consistent and high-quality.
• Participate in quality reviews and incorporate feedback to continuously improve labeling accuracy.
• Work within the team's annotation tools and workflow, and deliver assigned batches on schedule.

• Ability to hear and distinguish regional Vietnamese accents, with a particular strength in the Central region.
• Excellent Vietnamese language skills: spelling, punctuation, and capitalization; strong listening comprehension, including in noisy audio.
