+### **Dataset Card for Emolia**
+#### **Dataset Description**
+This dataset is an enhanced version of the Emilia dataset, enriched with detailed emotion annotations. The annotations were generated using models from the EmoNet suite to provide deeper insight into the emotional content of speech. This work is based on the research and models described in the blog post "Do They See What We See?".
+The annotations include 54 scores for each sample, covering a wide range of emotional and paralinguistic attributes, as well as an emotion caption generated by the BUD-E Whisper model. The goal is to enable more nuanced research and development in emotionally intelligent AI.
+**Emolia** provides **timbre speaker embeddings** per sample using **Speaker-wavLM-tbr** (Orange), which focuses on **global timbral characteristics** and is intended to be **less sensitive to transient prosodic/emotional cues** than typical speaker-ID embeddings. Background: timbre/prosody disentanglement has recently been explored to improve speaker modeling robustness, aligning with this model’s goal. ([Hugging Face][1])
+---
+#### **Dataset Structure & Access**
+The dataset includes the original Emilia audio data **plus**:
+* **Emotion annotations** (40 categories + 14 attributes + emotion caption).
+* **Timbre speaker embeddings** (vector per sample from Speaker-wavLM-tbr). ([Hugging Face][1])
+* **Characters per second (CPS)** statistic per sample.
+**Format:** WebDataset (sharded `.tar` files) containing audio and JSON/CSV sidecars for annotations, embeddings, and CPS.
+> Note: This repository **supersedes** earlier, interim multi-repo distributions. All links to those prior repositories have been removed.
+The original `.tar` files for the Emilia dataset are also included. Files belonging to the YODAS subset can be identified by a suffix in their filenames.
+---
+#### **Speaker Embeddings (Timbre-Focused)**
+* **Model:** Orange/**Speaker-wavLM-tbr** (WavLM-based).
+* **Intent:** Produce embeddings that **globally represent speaker timbre** and **de-emphasize emotion/prosody**, improving stability when emotional state varies. Use cosine similarity on embeddings for clustering/comparison, analogous to ASV, but with a **timbre emphasis**. ([Hugging Face][1])
+* **Background:** WavLM is a self-supervised model family designed for robust speech representation and speaker identity preservation; disentangling timbre from prosody has been shown to improve robustness in several tasks. ([arXiv][2])
+---
+#### **Derived Metric: Characters per Second (CPS)**
+For each utterance we compute **CPS = total\_characters / audio\_duration\_seconds**.
+CPS values are stored alongside the other per-sample annotations in this repository.
+---
+#### **Dataset Statistics**
+This combined dataset comprises approximately **215,600 hours** of speech, merging the original Emilia dataset with a large portion of the YODAS dataset. The inclusion of YODAS significantly expands the linguistic diversity and the total volume of data.
+The language distribution is broken down as follows:
+| Language  | Emilia Duration (hours) | Emilia-YODAS Duration (hours) | Total Duration (hours) |
+| :-------- | :---------------------- | :---------------------------- | :--------------------- |
+| English   | 46.8k                   | 92.2k                         | 139.0k                 |
+| Chinese   | 49.9k                   | 0.3k                          | 50.3k                  |
+| German    | 1.6k                    | 5.6k                          | 7.2k                   |

+| Japanese  | 1.7k                    | 1.1k                          | 2.8k                   |
+| Korean    | 0.2k                    | 7.3k                          | 7.5k                   |
+| **Total** | **101.7k**              | **113.9k**                    | **215.6k**             |

+#### **Interpretation of Scores**
+The models predict raw scores for 40 emotional categories and 14 attribute dimensions. For the emotional categories, these raw scores are also used to calculate a normalized Softmax probability, indicating the relative likelihood of each emotion.
+| Attribute             | Range    | Description                                              |
