| [**English Version**](./README.md) | |
| ## 关于数据集 | |
| **ExpressiveSpeech** 是一个高质量、**富有表现力**的**双语**(中英)语音数据集,旨在解决现有对话数据集中普遍存在的语音表达力不足的问题。 | |
| 该数据集精心整理自五个著名的开源情感对话数据集,分别是:Expresso、NCSSD、M3ED、MultiDialog 和 IEMOCAP。 通过严格的处理和筛选流程,ExpressiveSpeech 确保了每一段语音都在音频质量和情感丰富度上达到高标准。 此数据集专为需要高保真度、能引起情感共鸣音频的任务而设计,例如富有表现力的语音转语音(S2S)、文本转语音(TTS)、语音转换以及语音情感识别等领域。 | |
| ## 主要特点 | |
| - **高表现力**: 平均表现力得分高达 **80.2**,显著优于其原始来源数据集。 | |
| - **双语内容**: 包含均衡的中英文语音内容,语言比例接近 **1:1**。 | |
| - **数据规模可观**: 包含约 **14,000** 条语音片段,总时长达 **51** 小时。 | |
| - **丰富的元数据**: 为每条语音提供由 ASR 生成的文本转录、表现力得分以及来源信息。 | |
| ## 数据集统计 | |
| | 指标 | 数值 | | |
| | :--- | :--- | | |
| | 总语音条数 | ~14,000 | | |
| | 总时长 | ~51 小时 | | |
| | 语言 | 中文, 英文 | | |
| | 语言比例 (中:英) | 约 1:1 | | |
| | 采样率 | 16kHz | | |
| | 平均表现力得分 (DeEAR) | 80.2 | | |
| ## 我们的表现力评分工具:DeEAR | |
| 本数据集的高表现力是使用我们的筛选工具 **DeEAR** 实现的。如果您需要自己构建更大批量的高表现力数据,欢迎使用此工具。您可以在我们的 [GitHub](https://github.com/FreedomIntelligence/ExpressiveSpeech) 上找到它。 | |
| ## 数据格式 | |
| 数据集的组织结构如下: | |
| ``` | |
| ExpressiveSpeech/ | |
| ├── audio/ | |
| │ ├── M3ED | |
| │ │ ├── audio_00001.wav | |
| │ │ └── ... | |
| │ ├── NCSSD | |
| │ ├── IEMOCAP | |
| │ ├── MultiDialog | |
| │ └── Expresso | |
| └── metadata.jsonl | |
| ``` | |
| - **`metadata.jsonl`**: 一个 `jsonl` 文件,其中包含每条语音的详细信息。元数据包括: | |
| - `audio-path`: 音频文件的相对路径。 | |
| - `value`: 由 ASR 生成的文本转录。 | |
| - `emotion`: 来自原数据集的情感标签。 | |
| - `expressiveness_scores`: 来自 **DeEAR** 模型的表现力得分。 | |
| ## JSONL 文件示例 | |
| 每行 JSONL 包含一个 `conversations` 字段,其中存放语音轮次数组。 | |
| 示例: | |
| ```json | |
| {"conversations": [{"No": 9, "from": "user", "value": "Yeah.", "emotion": "happy", "length": 2.027, "score_arousal": 0.9931480884552002, "score_prosody": 0.6800634264945984, "score_nature": 0.9687601923942566, "score_expressive": 0.9892677664756775, "audio-path": "audios/Expresso/splitted_conversation/ex04-ex01/laughing/ex04-ex01_laughing_001/009_speaker1_53s_55s.wav"}, {"No": 10, "from": "assistant", "value": "What was the reason, what was the, why couldn't I get there, ah I forget.", "emotion": "happy", "length": 3.753, "score_arousal": 0.9555678963661194, "score_prosody": 0.6498672962188721, "score_nature": 1.030701756477356, "score_expressive": 0.9965837001800537, "audio-path": "audios/Expresso/splitted_conversation/ex04-ex01/laughing/ex04-ex01_laughing_001/010_speaker2_55s_59s.wav"}]} | |

| *注*:部分源数据集使用了 VAD(语音活动检测),可能会将一句话切分为多个片段。 | |
| 为保持对话完整性,我们通过特定规则将这些片段合并回完整语句。 | |
