The ‘DipCo’ data corpus is a new data set that was publicly released by Amazon to help speech scientists address the difficult problem of separating speech signals in reverberant rooms with multiple speakers.

The corpus was created with the assistance of Amazon volunteers, who simulated the dinner-party scenario in the lab. We conducted multiple sessions, each involving four participants. At the beginning of each session, participants served themselves food from a buffet table. Most of the session took place at a dining table, and at fixed points in several sessions, we piped music into the room, to reproduce a noise source that will be common in real-world environments.

Each participant was outfitted with a headset microphone, which captured a clear, speaker-specific signal. Also dispersed around the room were five devices with seven microphones each, which fed audio signals directly to an administrator’s laptop. In each session, music playback started at a given time mark. The close-talk recordings were segmented and separately transcribed.

## Sessions

Each session contains the close talk recordings of 4 participants and the far-field recordings from the 5 devices. The following name conventions are used:

* sessions have a ```<session_id>``` label denoted by ```S01, S02, S03, ...``
* participants have a ```<speaker_id>``` label denoted by ```P01, P02, P03, P04, ...```
* devices have a ```<device_id>``` label denoted by ```U01, U02, U03, U04, U05```
* array microphone have a ```<channel_id>``` label denoted by ```CH1, CH2, CH3, CH4, CH5, CH6, CH7```

We currently have the following sessions:

| **Session** | **Participants** | **Hours** **[hh:mm]** | **#Utts** | **Music start [hh:mm:ss]** |
| ----------- | ------------------------------ | ---------------------- | --------- | -------------------------- |
| S01 | P01, **P02**, **P03**, P04 | 00:47 | 903 | 00:38:52 |
| S02 | **P05**, **P06**, **P07**, P08 | 00:30 | 448 | 00:19:30 |
| S03 | **P09**, **P10**, **P11**, P12 | 00:46 | 1128 | 00:33:45 |
| S04 | **P13**, P14, **P15**, P16 | 00:45 | 1294 | 00:23:25 |
| S05 | **P17**, **P18**, **P19**, P20 | 00:45 | 1012 | 00:31:15 |
| S06 | **P21**, P22, **P23**, **P24** | 00:20 | 604 | 00:06:17 |
| S07 | **P21**, P22, **P23**, **P24** | 00:26 | 632 | 00:10:05 |
| S08 | **P25**, P26, P27, P28 | 00:15 | 352 | 00:01:02 |
| S09 | P29, **P30**, P31, **P32** | 00:22 | 505 | 00:12:18 |
| S10 | P29, **P30**, P31, **P32** | 00:20 | 432 | 00:07:10 |
The sessions have been split into a development and evaluation set as follows:

| **Dataset** | **Sessions** | **Hours** [**hh:mm**] | **#Utts** |
| ----------- | ----------------------- | ----------------------- | --------- |
| Dev | S02, S04, S05, S09, S10 | 02:43 | 3691 |
| Eval | S01, S03, S06, S07, S08 | 02:36 | 3619 |

The DiPCo data set has the following directory structure:
```bash
DiPCo/
├── audio
│ ├── dev
│ └── eval
└── transcriptions
├── dev
└── eval
```

## Audio

The audio data is converted into WAV format with a sample rate of 16kHz and 16-bit precision. The close-talk recordings were made by monaural microphone and contain a single channel. The far-field recordings of all 5 devices were microphone array recordings and contain 7 raw audio channels.

The WAV file name convention is as follows:

* close talk recording of session ```<session_id>``` and participant ```<speaker_id>```
* ```<session_id>_<speaker_id>.wav```, e.g. ```S01_P03.wav```
* farfield recording of microphone ```<channel_id>``` of session ```<session_id>``` and device ```<device_id>```
* ```<session_id>_<device_id>.<channel_id>.wav```, e.g. ```S02_U3.CH1.wav```

## Transcriptions

Per session, a JSON format transcription file ```<session_id>.json``` has been provided. The JSON files contains for each transcribed utterance the following metadata:

* Session ID ("session_id")

* Speaker ID ("speaker_id")

* Gender ("gender_id")
* Mother Tongue ("mother_tongue")
* Nativeness ("nativeness")

* Transcription ("words")

* Start time of utterance ("start_time")
* The close-talk microphone recording of the speaker (```close-talk```)
* The farfield microphone array recordings of devices with ```<device_id>``` label

* End time ("end_time")

* Reference signal that was used transcribing the audio ("ref")

The following is an example annotation of one utterance in a JSON file:

```json
{
"start_time": {
"U01": "00:02:12.79",
"U02": "00:02:12.79",
"U03": "00:02:12.79",
"U04": "00:02:12.79",
"U05": "00:02:12.79",

"U02": "00:02:14.84",
"U03": "00:02:14.84",
"U04": "00:02:14.84",
"U05": "00:02:14.84",
"close-talk": "00:02:14.84"
},

"nativeness": "native",
"ref": "close-talk",
"session_id": "S02",
"speaker_id": "P05",
"words": "[noise] how do you like the food"
},
```

本‘DipCo’语料库是亚马逊（Amazon）公开发布的全新数据集，旨在助力语音科研人员解决多说话人混响房间内的语音信号分离难题。

本语料库由亚马逊志愿者协助搭建，在实验室中模拟了晚宴场景。我们共开展多轮实验，每轮均有4名参与者。每轮实验开始时，参与者从自助餐台自取食物；实验大部分环节在餐桌进行，部分轮次中会定时向房间内播放音乐，以还原真实环境中常见的背景噪声源。

每名参与者均佩戴头戴式麦克风，可采集到清晰的专属说话人信号。房间内还部署了5台设备，每台配备7个麦克风，将采集到的音频信号直接传输至管理员的笔记本电脑。每轮实验中，音乐播放会在预设时间点启动。近距录音（close-talk）会被分段并单独标注转录。

## 实验轮次说明

每轮实验包含4名参与者的近距录音，以及5台设备的远场录音，命名规则如下：

* 实验轮次：使用`<session_id>`标识，格式为`S01, S02, S03, ...`
* 参与者：使用`<speaker_id>`标识，格式为`P01, P02, P03, P04, ...`
* 设备：使用`<device_id>`标识，格式为`U01, U02, U03, U04, U05`
* 阵列麦克风通道：使用`<channel_id>`标识，格式为`CH1, CH2, CH3, CH4, CH5, CH6, CH7`

当前已开展的实验轮次如下：

| **会话ID** | **参与者ID** | **时长 [hh:mm]** | **语句数** | **音乐启动时间 [hh:mm:ss]** |
| ----------- | ------------------------------ | ---------------------- | --------- | -------------------------- |
| S01 | P01, **P02**, **P03**, P04 | 00:47 | 903 | 00:38:52 |
| S02 | **P05**, **P06**, **P07**, P08 | 00:30 | 448 | 00:19:30 |
| S03 | **P09**, **P10**, **P11**, P12 | 00:46 | 1128 | 00:33:45 |
| S04 | **P13**, P14, **P15**, P16 | 00:45 | 1294 | 00:23:25 |
| S05 | **P17**, **P18**, **P19**, P20 | 00:45 | 1012 | 00:31:15 |
| S06 | **P21**, P22, **P23**, **P24** | 00:20 | 604 | 00:06:17 |
| S07 | **P21**, P22, **P23**, **P24** | 00:26 | 632 | 00:10:05 |
| S08 | **P25**, P26, P27, P28 | 00:15 | 352 | 00:01:02 |
| S09 | P29, **P30**, P31, **P32** | 00:22 | 505 | 00:12:18 |
| S10 | P29, **P30**, P31, **P32** | 00:20 | 432 | 00:07:10 |

实验轮次已划分为开发集与测试集，划分方式如下：

| **数据集** | **实验轮次** | **总时长 [hh:mm]** | **总语句数** |
| ----------- | ----------------------- | ----------------------- | --------- |
| Dev | S02, S04, S05, S09, S10 | 02:43 | 3691 |
| Eval | S01, S03, S06, S07, S08 | 02:36 | 3619 |

DipCo数据集的目录结构如下：
bash

├── audio
│ ├── dev
│ └── eval
└── transcriptions
├── dev
└── eval

## 音频数据说明

音频数据已转换为WAV格式，采样率为16kHz，位深为16比特。近距录音（close-talk）采用单声道麦克风采集，仅包含单通道音频；5台设备的远场录音均为麦克风阵列录音，包含7个原始音频通道。

WAV文件命名规则如下：

* 对应实验轮次`<session_id>`与参与者`<speaker_id>`的近距录音：
命名格式为`<session_id>_<speaker_id>.wav`，示例：`S01_P03.wav`
* 对应实验轮次`<session_id>`、设备`<device_id>`与麦克风通道`<channel_id>`的远场录音：
命名格式为`<session_id>_<device_id>.<channel_id>.wav`，示例：`S02_U03.CH1.wav`

## 转录文本说明

每轮实验均提供一个JSON格式的转录文件`<session_id>.json`，文件中为每条转录语句包含以下元数据：

* 实验轮次ID（"session_id"）
