# Dataset Card for Ambient Acoustic Context

The Ambient Acoustic Context dataset contains 1-second segments for activities that occur in a workplace setting. Each segment is associated with speaker_id.

## Dataset Details

Using Amazin Mechanical Turk, crowd workers were asked to listen to 1-second segments and choose the right label. To ensure the quality of the annotations, audio segments that did not reach majority agreement among the turkers were excluded.


### Dataset Sources

- **Paper:** https://dl.acm.org/doi/10.1145/3379503.3403535
- **Website** https://www.esense.io/datasets/ambientacousticcontext/index.html

## Uses

In order to prepare the dataset for the FL settings, we recommend using [Flower Dataset](https://flower.ai/docs/datasets/) (flwr-datasets) for the dataset download and partitioning and [Flower](https://flower.ai/docs/framework/) (flwr) for conducting FL experiments.

To partition the dataset, do the following. 
1. Install the package.
```bash
pip install flwr-datasets[audio]
```
2. Use the HF Dataset under the hood in Flower Datasets.
```python
from flwr_datasets import FederatedDataset
from flwr_datasets.partitioner import NaturalIdPartitioner

fds = FederatedDataset(
    dataset="flwrlabs/ambient-acoustic-context",
    partitioners={"train": NaturalIdPartitioner(partition_by="speaker_id")}
)
partition = fds.load_partition(partition_id=0)
```

## Dataset Structure

### Data Instances
The first instance of the train split is presented below:
```
{'audio': {'path': 'id_-kyuX8l4VWY_30_40_05.wav',
  'array': array([-0.09686279, -0.00747681, -0.0149231 , ...,  0.12243652,
          0.15652466,  0.0710144 ]),
  'sampling_rate': 16000},
 'speaker_id': 'id_-kyuX8l4VWY_30_40',
 'label': 7,
 'start': '69',
 'id': 8}
```
### Data Split

```
DatasetDict({
    train: Dataset({
        features: ['audio', 'speaker_id', 'label', 'start', 'id'],
        num_rows: 70254
    })
})

abstract = {Conversational agents are rich in content today. However, they are entirely oblivious to users’ situational context, limiting their ability to adapt their response and interaction style. To this end, we explore the design space for a context augmented conversational agent, including analysis of input segment dynamics and computational alternatives. Building on these, we propose a solution that redesigns the input segment intelligently for ambient context recognition, achieved in a two-step inference pipeline. We first separate the non-speech segment from acoustic signals and then use a neural network to infer diverse ambient contexts. To build the network, we curated a public audio dataset through crowdsourcing. Our experimental results demonstrate that the proposed network can distinguish between 9 ambient contexts with an average F1 score of 0.80 with a computational latency of 3 milliseconds. We also build a compressed neural network for on-device processing, optimised for both accuracy and latency. Finally, we present a concrete manifestation of our solution in designing a context-aware conversational agent and demonstrate use cases.},
