High-quality data capture at scale
Our proprietary Recording Studio includes technical checks and live session direction to ensure audio and performance quality. We securely deliver labelled training data, metadata, and transcripts, with QA applied throughout the process.
18k hours of custom conversational Voice Data across 9 languages
A Fortune 10 technology company needed a large, diverse dataset of conversational audio to train an AI model for more natural, human-like speech. Voices delivered 18,000 hours of scripted and spontaneous conversation across 9 languages, sourced from our global talent network, at a pace of 1,000 hours per week.
Pre-built voice datasets, ready when you are.
For projects that don’t need a custom build, our pre-built datasets offer a fast path to deployment without compromising on quality or compliance.

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.
Every recording is traceable to a named, consenting contributor with full documentation of how their voice is used and what rights they retain. Every dataset is fully consented, legally compliant, and traceable from speaker to model—giving your legal and compliance teams everything they need as data governance regulation tightens.
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.
