A Large-scale Dataset for Audio-Language Representation Learning
Authors: name: Luoyi Sun, name: Xuenan Xu, name: Mengyue Wu, name: Weidi Xie

The AI community has made significant strides in developing powerful
foundation models, driven by large-scale multimodal datasets. However, in the
audio representation learning community, the present audio-language datasets
suffer from limitations such as insufficient volume, simplistic content, and
arduous collection procedures. To tackle these challenges, we present an
innovative and automatic audio caption generation pipeline based on a series of
public tools or APIs, and construct a large-scale, high-quality, audio-language
dataset, named as Auto-ACD, comprising over 1.9M audio-text pairs. To
demonstrate the effectiveness of the proposed dataset, we train popular models
on our dataset and show performance improvement on various downstream tasks,
namely, audio-language retrieval, audio captioning, environment classification.
In addition, we establish a novel test set and provide a benchmark for
audio-text tasks. The proposed dataset will be released at
