What is an AI voice agent? Everything you need to know 

Ready to build better conversations?

Simple to set up. Easy to use. Powerful integrations.

Get started

Customer communications are becoming increasingly challenging. Sales and support teams are expected to “do more with less”, meet rising customer expectations, and provide seamless 24/7 service across multiple channels. Imagine having a tool that works around the clock, answering calls, resolving basic queries, and ensuring no customer is left unheard. That’s exactly what an AI voice agent does. 

An AI voice agent is a software tool powered by artificial intelligence to simulate human-like conversations over phone or voice platforms. It uses technologies like Natural Language Processing (NLP), Text-to-Speech (TTS), and Interactive Voice Response (IVR) to understand caller intent, generate responses, and even sync data with Customer Relationship Management (CRM) systems. 

But what exactly does this mean for businesses? And how can smaller teams leverage it to gain a competitive edge? Whether you're looking for a virtual receptionist, or to bring AI into your call center operations, let's dive into everything you need to know about AI voice agents, their real-world applications, and how they’re transforming the way businesses handle calls. 

How do AI voice agents work? 

While AI voice agents may seem human-like, the technology behind them is thoughtfully engineered.

1. Voice input handling 

An Interactive Voice Response (IVR) guides users through tailored menus to connect them to the right person, or in this case, AI voice agent. The AI agent receives the caller's input, i.e. a spoken request or question. Advanced speech recognition systems process the audio and convert it into text so the AI can understand it. 

2. Natural Language Processing (NLP) 

NLP is where the magic happens. It allows the AI to comprehend the intent and context behind the caller’s words. Whether it’s a request for store hours or a warranty query, NLP ensures clarity so the AI agent ‘understands’ what the caller is asking.

3. Response generation 

The AI agent then selects the most accurate and relevant response, often powered by pre-trained machine learning models. If a more nuanced response is required, it escalates the call seamlessly to a human agent, passing along relevant context.

4. Integration with CRM 

Advanced systems like Aircall’s AI Voice Agent can log call details, including caller information and conversation context, directly into CRM tools. This ensures a smooth journey for the caller, seamless team collaboration, and sets up human agents for effective follow-ups. Conversation intelligence then tracks the AI agent’s response quality and gathers actionable insights to improve performance in future if needed.

AI voice agents: Enhancing your day-to-day operations

AI voice agents are helping businesses of all sizes transform their operations across various functions. Here’s how:

1. Sales teams 

AI voice agents make sales teams more efficient by automating repetitive tasks and enabling agents to focus on leads that matter. 

• Outbound calling: AI can help prompt, guide and assess cold calls, pre-qualify leads, and provide follow-up reminders. 

• Call coaching: Analytics from AI conversations offer actionable suggestions to improve agent performance. Live, in-call guidance can also help human agents with objection-handling.

• Power Dialer integration: AI seamlessly works with tools like Aircall’s Power Dialer to save time on dialing multiple numbers, and boost outreach efforts. 

2. Customer support 

Speed and accuracy are critical in support functions, and AI voice agents can help deliver both. 

• Inbound call routing: Ensures every caller is connected to the right team or resource. 

• IVR-facilitated issue resolution: AI can answer frequently asked questions, including order tracking, refund requests, or troubleshooting in real-time.

• 24/7 availability: AI agents can handle out-of-hours inquiries, ensuring your team can log off for the day knowing your customers always get help when they need it.

3. Surveys and feedback 

Automating customer feedback collection has never been easier with AI-powered survey tools. 

• Survey calls: AI voice agents can call customers to collect feedback post-call or post-purchase. 

• Data analysis: Responses are logged and analyzed to uncover key trends and areas for improvement. 

AI voice agents vs. human agents 

How does AI compare to human agents? While both play crucial roles, here’s a quick comparison to help you understand where each excels:

Where AI works best: Handling high volumes of repetitive and straightforward tasks, like answering frequently asked questions or gathering caller details. 

Where humans work best: Navigating nuanced, sensitive, or emotional interactions that require emotional intelligence. 

The benefits of AI voice agents for SMBs 

AI voice agents aren’t just for enterprise-level businesses. In fact, small and medium-sized businesses (SMBs) arguably stand to gain the most from this technology. 

Why? Because it levels the playing field. Here are the top benefits for SMBs: 

• Faster response times: Customers get immediate responses to their questions, boosting satisfaction. 

• Peak/seasonal hours coverage: AI agents alleviate pressure on human teams during peak times or seasonal spikes. Plus, they can ramp up their responses during phone outages.

• Reduced costs: AI handles routine tasks, freeing up your human team for higher-priority work. 

• Improved data insights: Seamless CX and CRM integrations provide rich analytics to inform decision-making. 

• 24/7 service coverage: Businesses can extend their support hours without exhausting their team or overhiring staff to cover quieter hours.
