- Abstract summary: We propose ZerAuCap, a novel framework for summarising general audio signals in a text caption without requiring task-specific training.
Our framework exploits a pre-trained large language model (LLM) for generating the text which is guided by a pre-trained audio-language model to produce captions.
Our proposed framework achieves state-of-the-art results in zero-shot audio captioning on the AudioCaps and Clotho datasets.

- Abstract: Zero-shot audio captioning aims at automatically generating descriptive
textual captions for audio content without prior training for this task.
Different from speech recognition which translates audio content that contains
spoken language into text, audio captioning is commonly concerned with ambient
sounds, or sounds produced by a human performing an action. Inspired by
zero-shot image captioning methods, we propose ZerAuCap, a novel framework for
summarising such general audio signals in a text caption without requiring
task-specific training. In particular, our framework exploits a pre-trained
large language model (LLM) for generating the text which is guided by a
pre-trained audio-language model to produce captions that describe the audio
content. Additionally, we use audio context keywords that prompt the language
model to generate text that is broadly relevant to sounds. Our proposed
framework achieves state-of-the-art results in zero-shot audio captioning on
the AudioCaps and Clotho datasets. Our code is available at

- Improving Text-To-Audio Models with Synthetic Captions [51.19111942748637]
We propose an audio captioning pipeline that uses an textitaudio language model to synthesize accurate and diverse captions for audio at scale.
We leverage this pipeline to produce a dataset of synthetic captions for AudioSet, named textttAF-AudioSet, and then evaluate the benefit of pre-training text-to-audio models on these synthetic captions.

We extend this connection by linking images to text via an existing image captioning system.
This approach can be used for speech translation with just images by having the audio in a different language from the generated captions.
We investigate such a system on a real low-resource language, Yorub'a, and propose a Yorub'a-to-English speech translation model.

We propose three desiderata for captioning audio -- (i) fluency of the generated text, (ii) faithfulness of the generated text to the input audio, and (iii) audibility.
Our method is a zero-shot method, i.e., we do not learn to perform captioning.
We present our results on the AudioCap dataset, demonstrating that audibility guidance significantly enhances performance compared to the baseline.

We propose a conditional generative adversarial network (C-GAN) to improve diversity of audio captioning systems.
A caption generator and two hybrid discriminators compete and are learned jointly, where the caption generator can be any standard encoder-decoder captioning model used to generate captions.
The results show that our proposed model can generate captions with better diversity as compared to state-of-the-art methods.

The goal of audio captioning is to translate input audio into its description using natural language.
The proposed method has succeeded to use a pre-trained language model for audio captioning.
The oracle performance of the pre-trained model-based caption generator was clearly better than that of the conventional method trained from scratch.
