Custom speech data, built around your requirements.
Multilingual speech datasets for ASR, TTS, conversational AI and model evaluation. Designed, collected and linguistically validated by one scalable project team.
Consent-led collection · Built to specification · Delivered securely
The speech your model needs, not a dataset you have to adapt to.
Every dataset is configured by language, locale, accent, demographics, device, environment, domain and technical specification.
Dual-channel conversational speech
Natural two-person dialogue captured in separate, synchronized channels. Preserve turn-taking, overlap and interruptions while gaining clean speaker-level audio.
Scripted / read
Controlled speech for phonetic, lexical and domain coverage.
Spontaneous
Natural vocabulary, pace, variation and disfluencies.
Commands & wake words
Target phrases and negatives across speakers and devices.
Studio / controlled
High-fidelity expressive recordings for TTS and voice applications.
Real-world / noisy
In-context speech that reflects deployment conditions.
One team owns the project from first requirement to final dataset.
Clear quality reduces handoffs, recollection, and uncertainty.
Design
Turn model goals into scripts, prompts, speaker profiles, environments, metadata and acceptance criteria.
Recruit
Source and verify native speakers, voice talent or domain specialists.
Collect
Manage remote, studio or real-world recording in the required channel setup.
Validate
Check audio, transcripts, annotations, pronunciation, naturalness, coverage and consent.
Deliver
Package data, metadata and documentation for secure transfer in your required structure.
