Benefits of an AI voice assistant

With an AI-powered voice assistant that integrates with your CX solution, you can offer exceptional customer service at peak efficiency without increasing organizational costs. Below, we’ve broken down the most significant benefits of these AI voice assistants.

Improved productivity

AI voice assistants are powerful and tireless, handling routine inquiries and tasks like scheduling appointments, processing orders, or answering FAQs. With this constant support, human agents can focus on complex customer interactions that require empathy, critical thinking, and problem-solving skills. By delegating repetitive tasks and other responsibilities to AI voice assistants, agents can also focus on providing personalized customer service and building relationships, ultimately improving agent productivity and overall satisfaction.

Extended support hours

Integrating AI-powered voice assistants with your customer service solution enables your business to offer 24/7 support to your customers. While your human agents resolve nuanced interactions during regular work hours, digital assistants can provide timely answers and resolutions to less complex inquiries at all hours—regardless of the time zone or day of the week. With this level of customer support, businesses build trust by empowering customers to get the help they need.

Enhanced customer experiences

Voice assistants powered by AI are dynamic: They can respond to natural language and provide answers in a conversational style. These assistants also improve customer experiences by offering consistent, on-brand support across various channels, meeting customers where they are and in various languages.

Reduced organizational costs

By automating the routing and handling of routine tasks and inquiries, AI-powered voice assistants use intelligent automation to help customer service teams do more with less, leading to lower operating costs. Additionally, by providing 24/7 support and offering customers various self-service options, these assistants can help businesses provide customer support during off-peak hours without increasing headcount.

How to choose an AI voice assistant

Choosing the best AI voice assistant for your business requires research. You need to vet your options, demo prospective tools, and choose the option that will complement your existing systems.

Here are some key features and capabilities to consider during the vetting process:

  • Service solution integrations: Ensure the AI voice assistant integrates smoothly with your CX ecosystem, including your call center software and ticketing system so they can transfer customers to human agents while your team tracks and manages interactions.
  • Functionality: Look for the specific functions you need your voice assistant to offer, including multilingual customer support and ticket automation.
  • Privacy and security: Evaluate the AI assistant's security protocols and ensure they align with your company's data privacy policies.
  • Customization: Customizing responses and greetings is valuable for a more personalized customer experience (CX), so verify that the voice assistant will allow you to customize it.
  • Learning and adaptation: Choose an AI voice assistant that uses every interaction to continuously learn, adapt, and improve its responses over time.
  • Cost: Don’t blow your budget on an AI-powered voice assistant. Instead, compare pricing models and features to find a solution that fits your budget.
  • Customer support: For smooth implementation (and continued use), research how reliable and responsive the customer support delivered by the AI assistant provider is.
  • Reviews and ratings: Read online reviews and ratings from other businesses to gain insights into user experiences.

By carefully evaluating these factors—and demoing the products you’re most interested in—you can select an AI voice assistant that seamlessly integrates with your service solution and enhances your CX.
