Audio Data Collection Services for Speech AI
Audio Data Collection Services for Speech AI
Consent-based speech and audio datasets - multi-speaker, multi-accent, 100+ languages - collected worldwide through the HaiCrowd platform.
What is Audio Data Collection?
Audio data collection is the sourcing of real-world speech and sound recordings - scripted prompts, spontaneous conversation, wake-word commands and more - captured to a defined specification so they can train and evaluate Speech AI models. HaiData runs this collection through its own HaiCrowd platform, so every recording comes with informed consent, automatic metadata and multi-level quality control before it reaches your team.
The result is representative, ethically sourced audio you can license with confidence - the foundation of accurate speech-to-text, voice assistants and other voice AI systems.
