Training AI for the Real World: Inside Nexdata’s Multilingual Data Solutions

In an age where AI-powered conversations define how businesses connect with their customers, the quality of those interactions depends on one crucial element: the data used to train them. For Nexdata, this is both a science and an art — and it’s why they’ve earned recognition at the GSI Awards 2025 – Gold Standard in AI.

From Data to Dialogue

Nexdata’s Conversational AI Data Solutions are more than datasets — they’re the backbone of intelligent, multilingual, and culturally nuanced AI communication systems. With over 200,000 hours of speech datasets available for immediate use, the company delivers precisely annotated, real-world training resources that enable AI models to interpret, respond, and adapt with human-like accuracy.

What sets Nexdata apart is the breadth and depth of its offering:

• Multi-language coverage including English, Chinese, Korean, Japanese, and other 30+ languages.
• Multi-domain expertise spanning daily life, finance, insurance, e-commerce, education, healthcare and etc..
• Specialized datasets such as 743 hours of UK English spontaneous dialogue speech dataset, 633 hours of Japanese conversational speech, 222 hours of English (Korea), and multi-domain customer service dialogue text with over 90,000 conversation sets.

Industry Impact in Action

The results speak for themselves:

• Speech Recognition for Cantonese Customer Service – Delivered 1,000 hours of annotated Cantonese speech data with 95% sentence accuracy and a custom lexicon for character consistency.
• Speech Recognition for Mandarin Customer Service – Provided 5,000 hours of ready-made Mandarin voice datasets plus 1,000 hours of annotated voice data for specific scenarios, enabling a client to launch a customer service AI product within a month.
• Chatbot Knowledge Base Optimization – Expanded and refined a client’s chatbot knowledge base by adding and optimizing over 3,000 knowledge points, enhancing service quality and user experience.

Compliance, Security, and Trust

Nexdata’s commitment to data security is as strong as its technical capabilities. The company is fully compliant with GDPR, CCPA, PIPA, HIPAA, and holds ISO 27001, ISO 27701, and ISO 9001 certifications. This ensures every project is built on a foundation of privacy, trust, and regulatory adherence.

Why Nexdata Stands Out

• One-stop AI data services from collection to annotation
• 30+ annotation tools covering speech, text, image, video, and 3D point cloud data
• AI-assisted pre-recognition to accelerate annotation workflows by up to 5x
• Proven track record with global enterprises, AI companies, and research institutions

Looking Ahead

By delivering data that reflects the complexity and diversity of human communication, Nexdata isn’t just training AI — it’s training AI for the real world. With its multilingual, industry-specific, and security-first approach, Nexdata is shaping the next generation of conversational intelligence.
