# Dataset Card for Assignment 2
## Dataset Description (数据集简介)
This is a Chinese speech dataset created for LIN3046 Assignment 2.
It contains 50 short sentences recorded by a native Mandarin speaker.
The data is segmented into individual WAV files and annotated in the metadata.csv file.
* **Total Duration:** > 3 minutes
* **Language:** Chinese (zh)
* **Format:** WAV (44.1kHz, 16-bit)
* ## Reflection (反思与挑战)
During the creation of this dataset, I encountered and overcame several technical challenges:
1. **Audio Formatting:** Initially, I exported files with automatic numbering (e.g., `01-s001.wav`), which caused a mismatch with the `metadata.csv`. I learned to use Audacity's "Label/Track Name" export feature to ensure filenames strictly matched the IDs (e.g., `s001.wav`).
2. **Metadata Encoding:** I experienced issues with hidden formatting characters when editing CSV files on macOS. I resolved this by directly editing the `metadata.csv` on the Hugging Face web interface to ensure strict CSV formatting.
3. **Platform Latency:** I learned that server-side caching on Hugging Face can sometimes cause temporary `RowsPostProcessingError` alerts even when the data integrity is correct.
Through this process, I gained a deeper understanding of strict data formatting requirements in computational linguistics.
