Rights-cleared multilingual dataset catalog illustrating the Frontend & Conversational Voice — English + Hindi (Studio) dataset

Languages: English, Hindi (P0)
Scale: ≥10 hrs/speaker (up to 100)

Quality & methodology metrics

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.

Provenance & consent

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.

Methodology

Recorded from native English and Hindi speakers in the frontend/assistant and conversational registers, both read and semi-spontaneous, with natural code-switching. Segmentation spans sentence to paragraph level with timestamps. This is the P0 priority profile (4–5 English & Hindi speakers).
