What is AIxBlock?

AIxBlock provides enterprise training data for speech and large language models, offering voice, audio, and text datasets across 100+ languages.

The platform supplies ready-to-license audio catalogs, hundreds of thousands of hours of real-world call center and environmental recordings, and custom collection for exclusive use.

Services include multilingual collection, transcription, annotation, professional or natural-speaker recordings, and sound/environment capture for audio classification and noise detection.

Text and dialogue offerings cover conversation annotation, intent/entity labeling, RLHF preference data, and fine-tuning datasets for LLM training.

A self-hosted deployment option and storage connectors enable data sovereignty by keeping customer data on their infrastructure and preventing platform retention of collected data.

Enterprise-scale language coverage and integration options support ML engineers, data scientists, and AI teams building voice AI and LLM applications.
