DreamVoice Dataset
Introduction
The DreamVoice dataset is designed to support research in text-guided voice conversion and synthetic voice generation. The dataset is structured into three main files:
- dreamvoice_s1_raw_label.csv: Contains raw keyword votes from multiple experts. Each row represents the collective opinions of experts regarding various aspects of the speaker's voice characteristics.
- dreamvoice_s2_keyword.csv: Provides verified keywords for each speaker, serving as a reliable reference for their voice profile based on expert consensus.
- dreamvoice_s3_synthetic_prompt.csv: Includes synthetic timbre description prompts. These prompts are designed to describe the unique timbre characteristics of each speaker, facilitating the generation of synthetic voices that match specific timbral qualities.
Usage
To use the DreamVoice dataset in your research or projects, follow these steps:
Download VCTK and LibriTTS-R Datasets
The DreamVoice dataset is built to work with the VCTK and LibriTTS-R speech datasets. You can download them from the following links:Working with the Dataset
Once the datasets are downloaded, you can combine them with the DreamVoice dataset based on the column speaker_id.

Each keyword and descriptor plays a crucial role in accurately capturing and conveying the unique characteristics of each voice sample in the dataset.
Analysis and Enhancement
- Agreement scores used to prioritize keywords
- Rigorous reassessment for moderately agreed keywords
- For each speaker we atleast have age and gender keywords
- Other keywords are selected based on the Agreement scores
- We do not use any fine grained annotations for darkness and roughness in the model training
- Use of OpenAI's GPT4 for natural language descriptors
- Generation of descriptors based on all keyword combinations
Generated Descriptors Examples:
Speaker ID | WAV File | Keywords | Prompt |
---|---|---|---|
2562 | File 2562 | Male, Adult, Dark | An adult male voice, with a dark timbre. |
30 | File 30 | Female, Teenager, Bright | A teenage girl's voice, radiating brightness and energy. |
2156 | File 2156 | Male, Senior, Strong | A senior male voice, characterized by strength and power. |
