A quick look at how Graveiens AI partners with teams to deliver human data for AI models.
A usable voice corpus is more than recordings. We handle contributor sourcing and explicit-consent onboarding, recording management, then audio annotation services — transcription, speaker diarization, emotion and event labeling — with metadata tagging and four-stage QA on every file. The same pipeline supports ASR, TTS and voice-cloning data, and connects to our audio transcription services and data annotation services.
Build a voice datasetPrompted, scripted and conversational speech across accents, dialects and conditions — every dataset built on explicit consent with a full audit trail.
Speech models need volume, diversity and clean consent. Graveiens AI is built around consent-backed voice audio — we run the full pipeline from artist onboarding and recording management through metadata tagging and QA, delivering scripted and spontaneous speech across 25+ languages and a wide range of accents.
Every recording is captured with explicit consent and an auditable metadata trail, so your ASR, TTS and voice-assistant models train on data that is both high-quality and compliant.
Talk to our voice audio teamScripted, spontaneous and labelled speech for voice AI.
Read speech and prompted utterances for ASR and TTS across languages and accents.
Natural dialogue and call-style data for real-world speech recognition.
Speaker, emotion, event and quality labelling for fine-grained models.
Deep Indic plus major Asian and European languages, 25+ in all.
Representative speech-AI programmes we support.
Wake-word, command and dialogue data for assistants.
Transcribed and recorded speech for recognition and synthesis.
Call-style speech for support and analytics models.
Our differentiator is doing voice AI data the right way: explicit consent at onboarding, managed recording, rich metadata and QA on every file. You get a compliant, auditable dataset and are invoiced only for approved recordings — making a first voice pilot low-risk.
