There is no doubt that artificial intelligence has taken the whole technology platform to a new level. With the rising emergence of AI Voice Agents, multiple domains of human labor have become lightning-fast and not just easy.
From booking appointments to paying bills, setting reminders to chasing uncanny, realistic queries, everything is just a command away. Having said that, AI voice agents have evolved massively and reached beyond being just a command and response system.
Therefore, in this blog from ContactSwing, we are going to explore the world of AI Voice Agents; their functioning, and their contribution to enhancing a user-friendly experience
AI Voice agents are software systems that are designed explicitly with the help of Artificial Intelligence and are capable of communicating with users via speech. Now these systems use technologies such as speech recognition, natural language understanding, and text-to-speech (TTS) to interact with users in a conversational tone. Remember the last time you called a company and spoke to an automated system? Well, that is a basic example of an AI Voice Agent.
Because of their high-end accuracy and undeniable efficiency, they are integrated into multiple domains and industries such as customer support, healthcare, entertainment, and so on. These voice agents don’t just respond to your queries but also enhance the user experience by adding a human tone to the conversation that provides customers with a quick yet effective solution to their queries.
ContactSwings’s extensive research blog discusses the primary and most effective criteria based on which we chose a voice AI agent. Let’s have a look at those criteria in detail below.
There are a plethora of options when choosing the best AI voice agent, especially after such a breakthrough advancement of Artificial Intelligence. Having said that, it is crucially important to understand that an AI voice agent is not just meant to respond to queries but also react accordingly.
To ensure better communication and enhance customer satisfaction, it is of foremost importance to understand that an AI voice agent needs to cater to multiple dimensions that may include both solving queries as well as empathizing whenever the situation demands.
Therefore, choosing ‘the best’ among a wide variety of options could be tricky, but when the subject in question is a voice AI agent, there are quite a few parameters that need to be evaluated.
The process of making a voice AI agent perform better and accurately involves a lot of testing and trials. Hence, based on multiple criteria, an AI voice agent is evaluated. Let's have a look at some of these criteria below.
1. Intelligence Quotient
A good voice AI agent should be able to immediately respond to different questions, even when the same questions are rephrased in multiple ways. It should be able to respond to the point and must have sufficient pieces of information ready to validate the responses.
2. Quick and Fast Response
Imagine waiting for several minutes to get a response from a voice agent. Isn't it annoying? Being quick with responses and delivering fast solutions is the foremost evaluation factor of an AI voice agent.
3. Easy and Accessible
Setting up an AI voice agent might sound like rocket science, especially to those who aren't very interested in technology. Therefore, it is important to ensure that the process of installing a voice AI agent and usage techniques are handy and can be accessed from anywhere.
4. Multi-Lingual Support
For a voice AI agent to make it to the top choices, it needs to ensure that it can accept and understand commands in different languages, which would enable easy and real-time communication.
5. Data Process Update
A voice AI agent cannot function unless it is updated with a continuous flow of information. It should be ready to answer queries related to any topic and must be able to share information that is not just accurate but also updated. Therefore, it is extremely important to ensure updated data processing.
With the refinement of technology and programming, these voice agents are now even capable of handling in-depth conversations and mimicking human emotions.
