As the digital revolution accelerates, businesses are perpetually looking for technology that can simplify operations and enhance the customer experience.

Two technologies consistently mentioned in these conversations are Interactive Voice Response (IVR) and Intelligent Virtual Assistants (IVA), both pivotal in streamlining call flow and providing self-service solutions. Despite having similar
goals, these systems differ vastly in their approach to automating customer contact applications.

To help you navigate the IVA and IVR landscape,
we delve deeper into these technologies and explore
which solution, whether traditional IVR or a more advanced IVA, would best serve your contact center needs.

What is IVR?

Interactive Voice Response (IVR) is a telephony system
that can be integrated into your CRM to offer automated interaction with callers. It uses
pre-recorded voice prompts and menus, serving as a convenient channel for customers to self-serve or be
guided to the appropriate department.

IVR technology is a stalwart in contact centers with high call volumes, acting as customers’ initial point of contact. A long call queue can lead to a high call abandonment rate, which means fewer conversions. Instead of hiring people to manage high call volumes, you use IVR solutions for call management.

Depending on the options provided, a caller can get information or perform simple tasks using a touch-tone keypad
or voice commands. For instance, a customer might check account balances, pay bills, or get business operating hours using IVR. However, for more complex requests that the IVR system cannot handle, the call gets directed to a live agent.

By reducing the need for live agents to handle routine queries, IVR helps save both the customer’s time and the company’s resources. Because phone lines are always manned, there is less call abandonment due to long wait times when call volumes are high.

What is IVA?

Intelligent Virtual Assistant (IVA) is a leap forward from
IVRs. Infused with artificial intelligence (AI),
the IVA software delivers customers personalized, real-time voice
and text responses.

The primary difference between IVR solutions and IVAs is the intelligence level of the responses. IVAs gain natural language understanding (NLU) through natural language processing (NLP), sentiment analysis, and speech recognition. With NLU, they can replicate human conversations and interactions. They may also have voice biometrics recognition technology to safeguard account information.

These AI-driven intelligent virtual agents can converse, resolve queries, and even learn from past interactions to enhance future responses. The ability to interact across various channels, including web, mobile apps, and social media, marks a significant shift from IVR, enabling a more integrated customer service experience.

IVA vs IVR: The Differences

Choosing between IVR and IVA isn’t quite as simple. IVA isn’t a magic wand that will fix your existing IVR problems. Before upgrading from IVRs to IVAs, you must understand how they differ.

The key difference between IVR and IVA, despite their shared objective of making the experience better for the customer and contact center operations smoother, is in their functionality. IVA offers conversational AI, which can go beyond fixed scripts and adapt to situations to offer a flexible, responsive solution.

The contact center IVA solution is a testament to the strength of natural dialogue designs, progressive disclosure shadow prompts, turn-taking confirmation yes-no, and the use of DTMF tones in traditional IVR systems.

IVR technology offers a fixed menu of options to callers. It requires the customer to make choices using a touch-tone keypad or voice commands matching pre-set prompts.

IVA software, on the other hand, uses speech recognition technology to provide dynamic, conversational interactions. It employs AI and machine learning algorithms to comprehend customer queries, context, and sentiment, thereby offering interactive and conversational responses.

Benefits of IVR

IVR has stood the test of time, offering businesses considerable cost savings and efficiency. By handling routine tasks, it allows live agents to focus on more complex customer issues, improving overall productivity.
It’s a practical tool for organizations facing a high
volume of repetitive customer inquiries, routing callers to the best contact center agents for their requirements.

Drawbacks of IVR

Despite their proven benefits, these systems have limitations. The static IVR menu can frustrate customers if it fails to address their specific issues. Relying on touch-tone inputs or pre-determined voice commands can also feel restrictive and lead to customer dissatisfaction. If the IVR setup isn’t integrated with other systems, it could lack context about the caller’s history, leading to a disjointed customer experience.

If these are problems you’re facing, you should consider upgrading to an IVA system.

Benefits and Drawbacks of Using IVA

Benefits of IVA

IVAs leverage natural language processing to understand and respond to user queries more intuitively, providing a more human-like interaction. They can access and utilize customer data to deliver personalized responses and recommendations, improving customer satisfaction.

Since they are automated, IVA systems can operate around the clock, handling inquiries and tasks without requiring human intervention. They also improve efficiency, as automating routine inquiries and tasks allows live agents to focus on more complex and high-value interactions, enhancing overall productivity.

Drawbacks of IVA

Implementing and maintaining an IVA system can be more complex and costly compared to IVR systems, requiring advanced AI and machine learning capabilities. You may also have to deal with data privacy concerns. Handling large amounts of customer data raises potential privacy and security concerns, necessitating robust data protection measures.

The effectiveness of IVAs depends heavily on the quality and completeness of the data they are trained on. Poor data can lead to inaccurate responses and a subpar user experience. Despite advances in AI, IVAs can still misinterpret queries or fail to understand specific user accents or dialects. If that happens, it leads to errors and customer frustration.
