## Dataset Contents |
|
|
|
The dataset is organized into the following components: |
|
|
|
- **`wavs`**: Segmented audio files. |
|
- Note: Part 4 contains unsegmented data, and Part 5 is partially segmented. |
|
- **`text`**: Text prompts corresponding to the audio files. |
|
- **`lists`**: Recommended training, development, and test sets. |
|
- **`labs`**: Aligned HTS (Hidden Markov Model-based Text-to-Speech) labels. |
|
- **`emph_labs`**: Aligned HTS labels with emphasis markers on emphasized words. |
|
- `P:0`: Neutral words |
|
- `P:1`: Emphasized words |
|
- **`other`**: |
|
- Consolidated prompt files. |
|
- Question file for use during HTS training with the provided labels. |

## File Naming Conventions |
|
|
|
### Parts 1, 2, 3, and 5 |
|
Files are named using the format: |
|
`[style]_[type]_[session]_[id].[ext]` |
|
|
|
Where: |
|
- **`style`**: Speech style |
|
- `neut`: Neutral |
|
- `emph`: Emphasized |
|
- `expr`: Expressive |
|
- **`type`**: Content type |
|
- `parl`: Parliament |
|
- `book`: Book |
|
- `siwis`: SIWIS prompts |
|
- `sus`: SUS (Semantically Unpredictable Sentences) |
|
- `chap`: Chapter |
|
- **`session`**: Two-digit session identifier. |
|
- **`id`**: Four-digit unique identifier. |
|
- **`ext`**: File extension (`wav`, `txt`, `lab`). |
|
|
|
### Part 4 |
|
Files use the format: |
|
`chap_full.[ext]` |
|
|

|
## Additional Notes |
|
|
|
- **Speakers**: |
|
- Parts 1 to 4 feature recordings from the same main speaker. |
|
- Part 5 is recorded by a different speaker. |
|
- **Labels**: |
|
- Parts 1 to 3 include aligned labels. |
|
- Parts 4 and 5 lack labels due to their unsegmented nature. |
|

|
## Known Issues |
|
|
|
1. The `[s]` sound in "c'est" is frequently replaced with `[k]`, affecting label accuracy. |
|
2. In cases where multiple words are emphasized within a sentence, some emphasized words may not be labeled correctly. |
|
|

|
|
## TODO |
|
|
|
To improve the dataset: |
|
|
|
- Expand labels to include relative position information for emphasized words. For example, indicate the distance of an emphasized word relative to the current word. |
