Build data foundations for next generation voice AI.

Voice is one of the most important interfaces for AI. Speech systems are embedded throughout global industries. Access to high quality, human validated, ethical ASR training data can be a barrier to launching your model to global users.
DATAmundi helps you build the data foundations and unified workflows required to enable real-world multimodal and speech AI across languages and dialects.
Custom speech collected across languages, cultures, and devices for ASR training. Our multimodal Off-the-Shelf datasets are also available in multiple languages, licensed, and ready-to-use.
Combining proprietary AI transcription and human-in-the-loop for expert linguistic review.
Transform raw speech recordings into AI-ready datasets through multilingual linguistic annotation, semantic labeling, and metadata enrichment.
