摘要:

自动音频字幕(AAC)的问题之一是对应于音频事件/场景的词选择的不确定性。由于一个声学事件/场景可以用几个词来描述,因此它导致可能的字幕的组合爆炸和训练的困难。为了解决这个问题,我们提出了一个基于transformer的音频字幕模型与关键字估计称为TRACKE。它在执行声学事件检测/声学场景分类的子任务(即,关键字估计)。TRACKE估计关键词,其包括与输入音频中的音频事件/场景相对应的词集合,并且在参考估计的关键词的同时生成字幕以减少词选择的不确定性。在公共AAC数据集上的实验结果表明,TRACKE实现了最先进的性能,并成功地估计了标题及其关键字。

英文摘要:

One of the problems with automated audio captioning (AAC) is the indeterminacy in word selection corresponding to the audio event/scene. Since one acoustic event/scene can be described with several words, it results in a combinatorial explosion of possible captions and difficulty in training. To solve this problem, we propose a Transformer-based audio-captioning model with keyword estimation called TRACKE. It simultaneously solves the word-selection indeterminacy problem with the main task of AAC while executing the sub-task of acoustic event detection/acoustic scene classification (i.e., keyword estimation). TRACKE estimates keywords, which comprise a word set corresponding to audio events/scenes in the input audio, and generates the caption while referring to the estimated keywords to reduce word-selection indeterminacy. Experimental results on a public AAC dataset indicate that TRACKE achieved state-of-the-art performance and successfully estimated both the caption and its keywords.
