AI voice datasets for speech recognition, conversational AI, and speaker recognition — ready to license or built custom to your specs. Whether you need off-the-shelf datasets or fully custom voice data collection in 200+ languages, we deliver studio-quality, ethically sourced data in weeks.
No obligation · NDA available · Response within 24 hours
Your data is secure. No spam, ever. We typically respond within 24 hours.
Train accurate ASR models and voice command systems with diverse, high-quality speech recognition datasets and speech commands datasets tailored to your domain.
Build natural-sounding voice agents with production-grade conversational AI datasets. Need more coverage than Common Voice or open datasets provide? We deliver Common Voice-style datasets with better language coverage, cleaner audio, and full commercial licensing.
Develop robust speaker verification and identification systems with speaker recognition datasets and diverse multilingual voice datasets covering demographics your models need.
Off-the-shelf not cutting it? Our custom voice data collection services build custom voice datasets to your exact specifications — specific languages, demographics, scenarios, devices, and quality standards that match your model requirements.
Free datasets like Common Voice, LibriSpeech, or Speech Commands have their place — but production AI often needs more. Here's the difference.

See how teams use Andovar datasets to improve model performance
"Adding Andovar's Southeast Asian speech data to our training set reduced word error rate by 23% across Thai, Vietnamese, and Indonesian."
"We needed 50,000 hours of multilingual conversational data in 8 weeks. Andovar delivered on time with consistent quality across all 12 languages."
"Custom speaker verification data from Andovar let us skip months of internal collection. We deployed our voice auth feature 3x faster than planned."
