Machine Learning in Customer Support

Last Updated: July 2024

Machine learning in customer support is revolutionizing the way businesses interact with their customers, offering enhanced efficiency and personalized experiences. 

57% of small businesses and businesses are implementing machine learning to improve the customer experience.

Companies using machine learning in customer support can leverage advanced algorithms and data analysis, to predict customer needs, automate responses, and provide real-time solutions. 

So, without further ado, let’s dive in and explore how machine learning can help your business gain a competitive edge in the market.

What is Machine Learning?

Machine learning is a branch of artificial intelligence that enables systems to learn from data to further enhance their performance. It uses algorithms to create models based on sample data, known as “training data”. The system’s ability to predict outcomes improves as they continue to analyze more data. 

A common use of machine learning is the recommendations system employed by sites like YouTube, Amazon, Netflix, and Spotify. They collect what customers watch, purchase, and rate to provide tailored recommendations in accordance to the user’s preferences.

Machine Learning in Customer Support: Use Cases

By implementing machine learning, businesses can improve agent productivity, provide personalized experiences, and increase customer satisfaction. 

1) Issue resolution through predictive analysis

Using predictive analytic models you can anticipate customer issues and proactively resolve them. Predictive analytics models are extremely useful tools for estimating future results based on historical data. They are used to uncover patterns and trends, based on statistical algorithms which can be further used to make informed forecasts. 

Below are some ways in which businesses can employ predictive analytics models and machine learning in customer service: 

A) Customer Satisfaction

With predictive analytics models, businesses can analyze previous data such as purchase history, feedback ratings, and interaction patterns. This helps customer support agents to identify customers who are facing a problem and take proactive steps to satisfy their needs, enhancing customer loyalty. 

B) Customer Lifetime Value (CLV)

Businesses can deploy Customer Lifetime worth models that utilize data such as purchase history, customer behavior, and demographics to predict a particular customer’s future worth. This helps to sort high-value customers and provide tailored services to meet their demands and foster long-term partnerships. 

C) Service Escalation

Machine learning can be a powerful tool for service escalation by analyzing customer interactions and feedback. It helps predict when a customer issue might need to be escalated to a higher level of support, such as involving a supervisor or manager. This allows customer service teams to step in early and resolve problems before they get worse, leading to happier customers.

By looking at historical customer data, support teams can spot patterns and trends that suggest potential issues, such as fraudulent activity, equipment failures, or low employee retention. With this information, they can offer solutions before problems arise, reducing customer dissatisfaction and churn, and ultimately boosting customer satisfaction.

2) Speech Recognition for Customer Support

Call centers can combine machine learning with speech recognition technology to improve customer service. Here, machine learning can help to transcribe and analyze client calls, categorize them, and extract keywords to determine the sentiment or purpose. 

This can help support agents to route calls and provide accurate help for a better customer experience. 

3) Chatbots and assistants

Chatbots and virtual assistants driven by machine learning algorithms can be used to answer FAQs, and simple queries and assist with self-service options.  Additionally, chatbots with Natural Language Processing functions can understand customer requests to give accurate solutions. 

Below is an example of how a chatbot with NLP can transform the customer service experience: 

4) Feedback loop

Machine learning in customer service can be implemented to generate feedback by automating data analysis. It can help to extract insights from unstructured data sources and can condense the key points from forms, surveys, comments, and other feedback sources.

Furthermore, advanced machine learning tools can be used to highlight trends using client data. For example, Delighted AI uses statistical modeling that has been improvised using survey data. This enables you to catch repeating patterns based on unique feedback sets.

Moreover, as ML constantly improvises how the input is analyzed, customer support teams can get actionable insights to drive continuous development that directly addresses what is most important to their users.

5) Multilingual Customer Support

For companies operating on a global scale, machine learning can enable you to provide multilingual customer support and overcome language hurdles.

These systems can identify the language used in the user’s question and generate appropriate responses in the same language for seamless assistance in their native language.

6) Agent copilots

Machine learning coupled with NLU-powered AI can be used to provide support agents with relevant information based on customer interaction. Without an AI copilot, an agent has to manually locate the files while assisting the customers through the chat. As a result, clients may become frustrated with the delay. 

An AI model with semantic intelligence makes this interaction seamless and improves the client journey. This enables agents to focus on the customer without having to spend time searching for information. 

7) Create and update content

40% of the customers state that it’s difficult to find what they’re looking for within the knowledge base. Here, machine learning can be implemented to analyze the data from support tickets and transform it into useful insights or articles for the agent’s use.

Additionally, agents can use such suggestions to improve the articles in the knowledge base, making it easier for customers to find the answers they want. 

8) Interactive Voice Response

Machine learning can greatly enhance IVR (Interactive Voice Response) automation, making customer interactions more efficient and user-friendly. Traditional IVR systems have long been used to automate simple tasks and route calls, but new conversational IVR systems powered by AI take this a step further.

1) Voice Biometrics for User Verification

Machine learning enables IVR systems to verify users through voice biometrics. This means that instead of answering security questions, customers can be identified by their unique voice patterns, making the process quicker and more secure.

2) Natural Language Processing (NLP)

With the help of NLP, customers can directly tell the IVR system what they need in a conversational manner. For example, instead of navigating through multiple menus, a customer can simply say, “I want to check my account balance,” and the system will understand and respond appropriately. This simplifies the customer experience and reduces frustration.

3) Visual IVR Systems

Some companies use visual IVR systems through mobile apps to make interactions even easier. These systems present organized menus and options visually on a screen, allowing users to select what they need without listening to long lists of choices.
