⚠️Data Availability

Full access requires internal approval and a research-only data use agreement. 🚫 Non-Commercial Use This dataset is provided for non-commercial research and education only. Commercial use is prohibited.
Researchers who wish to request full access may contact [email protected] with a brief description of their affiliation, project goals, intended use, and data protection plan. Only de-identified data may be shared, and redistribution is prohibited.

🗂️ Data Release & Access

• Public release (partial subset): We release only a portion of the data used for this benchmark’s training and evaluation. This Lite subset differs in amount and coverage from our internal full dataset and is not a drop-in replacement for the complete data.
• What’s included: A reduced selection of dialogues/audio/text sufficient to reproduce the reported benchmark protocol at a smaller scale.
• Not included: Additional sessions, higher-fidelity artifacts, and full validation/test coverage remain internal.

🔒 Privacy, Safety & Redaction

• Privacy-preserving audio: To protect speaker privacy, all audio has been re-synthesized via TTS (privacy-preserving re-encoding). This process obfuscates speaker identity and acoustic biomarkers while preserving task-relevant linguistic content for modeling.
• Real-world dialogs: The dialogue content originates from real-world collections. However, sensitive spans (e.g., direct identifiers, highly specific personal details) are automatically redacted by an LLM-based filter before release.
• Residual risk: Despite these protections, re-identification attempts are prohibited. Please do not try to recover original identities or link samples to outside sources.
