Four Types of Audio Annotation
Comprehensive annotation methodologies for every audio analysis need
Sound Annotation & Labeling
Identify and tag specific sounds within audio files—from music notes to environmental noises—creating structured datasets for acoustic recognition models.
Event Tracking
Mark temporal boundaries of audio events with precise timestamps, tracking when sounds start, end, and overlap for sequential pattern analysis.
Speech-to-Text Transcription
Convert spoken words into accurate text transcripts with speaker identification, enabling natural language processing and conversational AI training.
Audio Classification
Categorize entire audio segments by type, quality, emotion, or content—building taxonomies for automated audio content understanding.
Annotation Capabilities
Speech Metadata Tagging
Add contextual metadata including speaker identity, emotion, accent, language, and speech clarity for nuanced AI understanding.
Sound Event Detection
Pinpoint specific acoustic events like door slams, alarms, music, applause with millisecond precision and confidence scoring.
Human-Bot Interaction
Label conversational turns, intents, entities, and dialogue flow for training virtual assistants and chatbots.
High Accuracy Labeling
