Frequently Asked Questions
Voice data is recorded human speech used to train and improve AI models—powering speech recognition, virtual assistants, conversational AI, accessibility tools, and more. It helps machines better understand and respond to human speech across languages and speaking styles.
Open-source datasets have serious limitations: inconsistent recording environments, variable audio quality, and unclear provenance and licensing. Voices datasets are recorded by professional contributors in studio-grade environments, with script direction, rigorous QA, and consistent metadata at every stage—fully licensed and consented for AI model training.
Yes. Every custom dataset is scoped around your exact requirements before recording begins—whether you’re building for ASR, TTS, or conversational AI. Custom scripts, emotion and tone tagging, and metadata structured to your technical specs are all included.
Never. Recordings shared for Voice Over jobs are only ever used for that purpose. Voice Data for AI is sourced separately through dedicated, consented data collection—with clear separation between Voice Over work and Voice Data to ensure full transparency.
Every dataset goes through structured quality assurance before delivery—covering audio quality checks, transcript and labeling reviews, and validation against your technical specifications. Nothing is signed off until it meets our standards.
