PRECISE AUDIO WORKFLOWS

AI‑accelerated processing with expert human validation.

Our model‑assisted pipelines integrate ASR pre‑transcription, diarization, and acoustic tagging, then route data through vetted annotators for contextual labeling and verification. From speech segmentation to intent tagging, every annotation is traceable, versioned, and quality‑checked to meet enterprise compliance standards.

Speaker Diarization

Identify and label speakers in multi‑party audio.

Transcription Alignment

Map spoken content with timestamps and word‑level alignment.

Intent & Entity Tagging

Structure conversational data for chatbot, IVR, and NLP models.

Acoustic Event Labeling

Annotate background sounds, noise types, or environmental cues.

Emotion & Sentiment Annotation
