Measured, audited, reproducible
Audio: WAV (PCM), mono, 48 kHz (min. 44.1 kHz), 24-bit — studio-recorded (professional studio preferred; treated home studio with prior approval).
Transcripts: both verbatim and normalized, with documented handling of numbers, dates, currency, time, URLs, email, abbreviations, symbols and punctuation, and native code-mixing.
Annotation: emotion, paralinguistics, disfluencies and prosody/emphasis applied pre-delivery by native-speaker annotators. Inter-annotator agreement (Cohen's / Fleiss' κ) is reported per annotation type as our QA standard, with a two-pass QA and adjudication workflow.
Deliverables: audio (WAV); transcripts (TXT/CSV/JSONL); annotations (JSON/JSONL/CSV); metadata (JSON/CSV).
Exclusions warranted in writing: no music/singing, no synthetic or TTS-generated audio, no copyrighted material, no ASR-style/web-scraped data.
All audio originates from human speakers recorded in vendor-owned, controlled studio sessions under written contributor agreements that grant commercial reuse, including explicit consent for AI training and commercial voice-cloning / synthetic-voice generation. Never scraped, never repurposed from call-centre or telephony recordings.
A specialized corpus of paralinguistic and expressive events: conversational fillers (um, uh, ah, er, hm, mm), backchannels, laughter, cheering, exclamations, physiological sounds (sigh, inhale, cough, throat-clearing) and expressive modifiers (whisper, shouting, emphasis) — the required taxonomy — plus disfluencies (filled pauses, false starts, repetitions, repairs, hesitations, elongations). A sample annotation file is included.
