+# DataHive — Vietnamese Conversations
+
+Unscripted conversations in Vietnamese between people who already know each other. Shared to support research on natural conversational voice models.
+
+## Why These Conversations
+
+Natural conversation depends on timing: when to respond, brief acknowledgments, pauses, and interruptions. People who know each other share context, leave thoughts unfinished, and switch turns without explicit signals. These recordings capture that.
+
+## How We Collect
+
+Participants call people they know through the Hive Calls app ([Google Play](https://play.google.com/store/apps/details?id=app.dhive.calls), [App Store](https://apps.apple.com/app/hive-calls/id6812719492)). They choose their own topics, with no scripts. Conversations take place in everyday environments and are recorded through LiveKit, with each participant saved separately using Opus compression in an Ogg container. These recordings are converted to stereo MP3 for this sample. Participants are paid for qualifying conversation time.

+Install the Hugging Face audio dependencies, then load the dataset from the extracted folder:
+
+```sh
+python -m pip install "datasets[audio]"
+```
+
+```python
+from datasets import load_dataset
+
+ds = load_dataset("audiofolder", data_dir="preview")
+```
+
+## Quality and Selection
+
+Every conversation passes QA review and automated checks for:
+
+- **Audio:** noise, signal-to-noise ratio, clipping, silence.
+- **Dynamics:** both speakers participate, turn-taking, overlap, interruptions, gaps.
+- **Content:** the same language on both tracks, topic, explicit content.
+
+Conversations are at least two minutes long. Repeat appearances by the same speaker are limited. Labels and measurements are automatic.
+
+## Consent and Privacy
+
+Participants explicitly consent to recording, sharing with customers, and AI model training. Conversations flagged for personal information are excluded. Metadata contains no names, phone numbers, or account IDs. Audio and transcript redaction is available on request.
+
+## Custom Collections
+
+We collect conversations for voice-model labs by language, accent, and requirements. Deliverables can include separate speaker tracks, transcripts, and quality metadata. On request, we can arrange collection of audio captured on-device before lossy compression, delivered as PCM WAV or FLAC. Contact [contact@datahive.ai](mailto:contact@datahive.ai).
