 that you need to understand about Vietnam.
Vietnam is a friendly and safe place to travel in. Thus, if you plan to spend your holidays in Vietnam, expect a trip that is trouble free and smooth. Many tourists who visit the nation complains of over-aggressive street vendors as well as operators with a bad attitude. However, you need to plan yourself well and avoid such problems. If you don’t know anything, don’t even bother asking its price. Such an attitude will help you avoid the vendors that will ensure that you buy some of their products before you part ways.
The greetings are not different from western countries. There are no formalities that are required when greeting a person. Thus, feel free to shake your hand with anyone and expect a warm welcome. People in Vietnam wear conservatively. Although the place is too hot, ensure that you don’t show much of your skin. The aspect will draw more attention, as well as stares, form the locals, and in the long run, you might be at risk of being sported by evil people. Dress well as you visit pagodas. Avoid wearing shorts or tatty beer t-shirts. Make an effort of following what the locals do to enhance your safety. Don’t openly condemn their ways of doing things, otherwise you might land yourself into troubles.
You don’t have to drink a lot of bottled water. The aspect will draw more attention to your naivety. There is no need of carrying huge bottles of water as vendors will reach you before you find them. Ensure that your cash, as well as credit cards and tickets, are in a safe place. Certificates, as well as other traveling documents, should be at an accessible location so as you can avoid unnecessary arrests.
You don’t have to wear a lot of jewelry or take your bag with you as you travel. Although violent crime is highly unusual in Vietnam, petty crime is more apparent. Thus, you need to be vigilant and more careful as your visit to Vietnam. If you were traveling using a motorbike or a taxi, make sure that your bag if any are well kept and not accessible to grabbing. In most cases, tourists complain of bag grabbing as they walk around the cities in Vietnam.
Losing tempers in Vietnam means a loss of your face. Keep a cool head, and in the long run, you will have a higher chance of getting what you want. For the safety of your family, avoid showing affection in public. It is worth noting that you are in Vietnam one of the developing nations. Thus, things might not be working as you are used to. However you don’t have to be paranoid about your safety, what you need to do is be aware of your surroundings. By so doing, you will ensure that your family and friends are safe and ready to have more fun as they travel in the land.
Vietnam is a safe place to visit. What you need to do in an attempt to boost your safety is understanding your environment and being keen on how you handle and interact with the local people in the nation.

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.


Introduction
Automated audio captioning (AAC) is an intermodal translation task when translating an input audio into its description using natural language [1][2][3][4][5]. In contrast to automatic speech recognition (ASR), which converts a speech to a text, AAC converts environmental sounds to a text. This task potentially raises the level of automatic understanding of sound environment from merely tagging events [6,7] (e.g. alarm), scenes [8] (e.g. kitchen) and condition [9] (e.g. normal/anomaly) to higher contextual information including concepts, physical properties, and high-level knowledge. For example, a smart speaker with an AAC system will be able to output "a digital alarm in the kitchen has gone off three times," and might give us more intelligent recommendations such as "turn the gas range off." One of the problems with AAC is the existence of many possible captions that correspond to an input. In ASR, a set of phonemes in a speech corresponds almost one-to-one to a word. In contrast, one acoustic event/scene can be described with several words, such as {car, automobile, vehicle, wheels} and {road, roadway, intersection, street}. Such indeterminacy in word selection leads to a combinatorial explosion of possible answers, making it almost impossible to estimate the groundtruth and difficulty in training an AAC system.
To reduce the indeterminacy in word selection, conventional AAC setups allow the use of keywords related to acoustic events/scenes [4,5]. The audio samples in the AudioCaps dataset [4] are parts of the Audio Set [10], and their captions are annotated while referring to the Audio Set labels. Therefore, automatic text generation while referring to keywords (e.g. Audio Set label) may restrict the solution space and should be effective in reducing word-selection indeterminacy.  Unfortunately, in some real-world applications such as using a smart speaker, it is difficult to provide such keywords in advance. For example, to output the caption "a digital alarm in the kitchen has gone off three times," conventional AAC systems require the keywords related to the acoustic events/scenes such as {alarm, kitchen}. However, if the user can input such keywords, the user should know the sound environment without any captions. This dilemma means that we need to solve the word-selection indeterminacy problem of AAC while simultaneously executing the traditional sub-task of acoustic event detection (AED) [6,7]/acoustic scene classification (ASC) [8] 1.
We propose a Transformer [12]-based audio captioning model with keyword estimation called TRACKE, which simultaneously solves the word-selection indeterminacy problem of AAC and executing the AED/ASC sub-task (i.e. keyword estimation). Figure 1 shows an overview of the training procedure of TRACKE. TRACKE's encoder has a branch for keyword estimation and its decoder generates captions while referring to the estimated keywords for reducing word-selection indeterminacy. In the training phase, a set of ground-truth keywords is extracted from the ground-truth caption, and the branch is trained to minimize the estimation
