Multilingual Chatbot

A multilingual chatbot is a chatbot created to communicate with users in multiple languages. The bot understands and answers prospects’ inquiries in the languages they use to type these messages. It starts the flow either automatically after detecting the language or after allowing users to choose their preferred language.

In this article, we’ll unveil the importance and benefits of multilingual chatbots, find out how they work, review challenges you might face during their creation, and provide use cases and tips.

Why are multilingual chatbots becoming important?

With the power of social media and messaging platforms, businesses can significantly expand their global reach. Once companies decide to enter new markets and reach diverse audiences, that’s where multilingual chatbots come into play. Besides their global reach and accessibility, they are essential for several additional reasons, which we’ll cover below.

• More conversions. When users get all the necessary information instantly, they can take the desired action without any hesitation. If they wait for hours to communicate with human agents to get their answers, they can change their minds quickly because of your customer service. Multilingual chatbots prevent miscommunication and provide quick answers, enabling users to make purchasing decisions more easily and without obstacles.
• Around-the-clock support in different languages and time zones. You can provide support 24/7, regardless of people’s time zones and languages, without hiring specialists for different languages. E-commerce, SaaS, and travel companies that require assistance around the clock successfully incorporate multilingual chatbots to deliver all necessary information, make bookings, and update orders on autopilot. This way, you prevent customers from waiting for hours to connect with human agents.
• Compliance. Some countries require businesses to provide assistance and support in local languages, and this is supported by law. Multilingual chatbots help you comply with these rules and ensure seamless support at any stage of the buyer journey.

Now that you understand the importance, let’s proceed to the benefits that multilingual bots offer businesses. They'll help you determine whether you can achieve your goals using them.

Benefits of Multilingual Chatbots

If your chatbot can provide answers in multiple languages, it simplifies the purchasing process for your brand and helps you stand out. Yet, these are not the only perks that multilingual bots offer. Here are some additional options for you to consider before implementation.

• Cost-effectiveness. A multilingual chatbot enables you to avoid building multiple bots for different languages, saving you time and costs. With its help, you’ll be able to manage international audiences seamlessly. Besides managing multiple markets, this chatbot allows you to save costs associated with hiring customer support agents for different languages.
• Competitive advantage. This is a great opportunity to stand out among dozens of competitors that still use English to reply to FAQs, update order status, share special offers, onboard new customers, and more. Although these people may know English, it would be much nicer, clearer, and more convenient for customers to receive all the information in their native language. Besides, this approach demonstrates cultural awareness and shows that your business is customer-centric, prioritizing your clients’ needs, preferences, and challenges.
• Better customer experience. Customer support has a significant impact on the overall experience with your business. Having a multilingual chatbot prevents problems related to miscommunication and misinterpretation. When users receive replies in their own language, they are more satisfied with your service.
• Higher engagement. When users understand the language your chatbot uses, they are more likely to engage with your brand. They feel more comfortable asking questions in their native language. Additionally, this chatbot can personalize conversations in their language, increasing satisfaction and strengthening relationships with customers worldwide.

Knowing the advantages isn’t enough; if you want to incorporate multilingual chatbots, you need to understand how they work.

How does a multilingual chatbot work?

Before building a multilingual chatbot, it is essential to understand how it works. We’ll provide a brief explanation of this process. So let’s dive in.

Some businesses prefer to let customers choose the language for further conversation. They can do it using the menu. In other companies, the process begins with the chatbot identifying the language people use when they enter their inputs. NLP or a language detection API enables bots to analyze the message. After identifying the language, the bot can use predefined manual translations or real-time machine translation. The first one ensures high-quality translation and content tailored to a specific location, while the second one can have some deviations in the content.

If users decide to change languages during the chat, the chatbot should allow them to do so seamlessly and save the previous conversation. The chat continues without having to start over again. Responses are adjusted based on the information customers have provided previously.

The chatbot utilizes decision trees, which may vary depending on the language users select. The bot’s responses might vary depending on the region’s currency, formats, and tone. Besides, like all chatbots, multilingual bots allow human handoff options. If they are unable to handle some complex problems, these inquiries will be forwarded to human agents for resolution.

Now that you know how a multilingual chatbot works, let’s jump into the next section to uncover the challenges of building such a chatbot. These are essential to be aware of.

Challenges of Building a Multilingual Chatbot

Although multilingual chatbots carry a lot of benefits for businesses, you can also come across some challenges. You need to be familiar with them before diving into the development process.

• Cultural differences. Language isn’t only about translation but also about the cultural aspects it carries within. A bot can’t always communicate tone, formality, idioms, and cultural norms using another language. Therefore, some jokes and idioms may not be accurately reflected when translated.
• Accurate language detection. It can be problematic for a chatbot to instantly recognize the language after the user types only a few words. This is especially challenging when customers mix different languages in their text messages. It can result in incorrect language, a poor user experience, and low-quality answers, leading to dissatisfied customers.
• Translation quality. The quality of the translation might not always meet your and users’ expectations. Machine translation sometimes fails to convey the context, tone, and slang, whereas manual translation requires time and resources to be completed.
• Maintenance effort. You need to create separate flows for each language and update scripts, which means there’s more room for errors and inaccuracies. This can lead to poor customer experience with your chatbot and lower customer satisfaction.

Now that you know the challenges, it’s time to reveal the use cases. They will help you find out how you can benefit from multilingual chatbots while connecting with international audiences.

Use Cases for Multilingual Chatbots

There are various scenarios where you can apply multilingual chatbots. In this section, we’ll review the most common use cases for you to consider. So let’s dive in.

E-commerce and retail

If customers buy products online, they can do it more easily when using their native language. A multilingual chatbot in this industry is valuable for recommending products, tracking orders, making returns, and providing information on shipping to international audiences. Customers can also take advantage of a multilingual live agent handoff if such an option is available.

Travel and hospitality

Travel chatbots enable travellers to book flights, hotels, or tours using a language they prefer. With this bot, users have instant assistance in case they face cancellations, check-ins, or itinerary updates. It helps get responses to FAQs related to the trips, like visa requirements, hotel information, airport directions, tours, etc.

Customer support

Multilingual chatbots are especially useful for ensuring seamless customer service without requiring human agents to be involved. They are available 24/7, meaning that customers in different countries can contact your company at any time without having to wait for working hours. Businesses can automate answers to FAQs in multiple languages and provide all the necessary information using the customers’ native languages.

Education

Multilingual chatbots can be particularly helpful for students signing up for online courses. With the bot, they’ll get all the assistance they need for proper onboarding and accessing study materials. Having a chatbot also allows online schools available worldwide to provide students with technical help and progress tracking.

Healthcare

Healthcare chatbots enable patients to communicate in their own language when scheduling appointments and screening symptoms. Your medical institution can deliver treatment instructions and medication reminders without worrying about potential misunderstandings. Multilingual bots are essential for healthcare institutions that cater to international patients to prevent any confusion.

Now that you know the most common use cases, it’s time to jump into the tips.

8 Tips for Creating a Multilingual Chatbot

You can create different multilingual chatbots, but no one can guarantee their quality. However, there are recommendations you should follow to ensure a smooth customer experience.

1. Add the languages your audiences speak. Consider researching to determine which languages are most popular among your customers. Although you can’t add all languages, you can choose those that are native to your audience segments. Focus on your traffic, customers, and regions, and use CRM with analytics to choose your top 2-3 languages.
2. Allow users to choose a language at the start. You can either allow users to select the language that suits them best or use automatic detection, if possible, within your platform. The earlier they switch to their native language, the better for understanding and satisfaction with your customer service.
3. Create scripts for each language. It’s always better to develop separate scripts for each language rather than rely solely on machine translation. By creating dedicated flows, you can adjust your scripts to accommodate cultural differences, tone, and formality. You’ll also be able to localize your content, as currency and date formats typically vary by region. Native speakers and translators will assist you in ensuring everything is done properly for your chatbot.
4. Stay consistent with content. Consider using a single source for all scripts to ensure consistency in your content across all languages. Ensure that there are no discrepancies in pricing and other details related to your products and services. All the updates should also be reflected in each of your scripts to avoid confusion and dissatisfaction among customers.
5. Choose a platform supporting multilingual chatbots. If you are 100% sure you need a multilingual chatbot, look for chatbot builders that support this functionality. Language-based branching logic, NLP for multiple languages, translation APIs, and RTL support are a must for such a bot.
6. Let users switch languages mid-chat. Ensure that your chatbot is flexible, allowing users to switch languages at any time. Let them switch languages mid-chat if necessary. There may be several reasons for this, including the use of incorrect language or a poor translation, which can cause confusion.
7. Train NLP models. Consider developing language-specific training data to help your chatbot understand how to respond to specific inputs. This training will also enable it to accurately determine user intents.
8. Forward to human agents with the necessary language. If the problem is complex and requires human assistance, you should route the chat to an agent who speaks a specific language. This is very important because the likelihood that users won't understand your human agents if they speak languages other than English is high.

Having an international audience is great, especially when you can ensure all the necessary support is available in their native languages. With multilingual chatbots, you not only improve efficiency and productivity but also make people from different countries satisfied with your company. With the right approach and implementation, you can effectively support your existing customers and even expand your audience.
