AI Voice Agents for B2B

B2B buyers need help before they are ready to convert. They may have questions about use cases, integrations, or pricing. Some of them may not even know if your product is the right fit. 

But your sales team can't be available 24/7 to support them. And text-only chats are, let’s admit it, slow and inconvenient. 

That's why you need AI voice agents. They are intelligent software programs that let visitors talk directly to your website. These AI agents can answer questions, guide decisions, qualify intent, and close more sales. And they satisfy over 70% of B2B decision-makers who prefer remote human interaction or digital self-service.

In this blog, we will see how AI voice agents can convert website visitors into qualified pipeline and how you can build one for your website. 

6 ways AI voice agents can improve website conversions 

Let's understand how these AI agents help B2B teams turn passive website visitors into high-value leads.

1. Engages visitors proactively 

An AI voice agent doesn't wait for visitors to take action. It makes the first move by inviting them to start the conversation at the right moment. It shows a call bar, which feels like the website is calling the visitor. This helps you engage them before they leave and lower your bounce rates significantly. And research shows that 70% of customers like brands that offer proactive service.

2. Acts like a sales and support pro

A good AI voice agent is trained on your knowledge base. It knows everything about your products, pricing, positioning, and audience. And it's equipped with world-class sales and support strategies to deliver an exceptional user experience.

This enables the AI agent to answer visitor queries, explain use cases, handle objections, and guide visitors through your sales funnel. And if it can’t answer a query, it can smoothly transfer the chat to a human rep. 

3. Gives real-time recommendations

Advanced voice AI agents, like those powered by Expertise AI, show relevant resources based on the conversation. They can show:

  • Product pages
  • Calendars
  • Case studies
  • Blog posts
  • Pricing page
  • Each recommendation is personalized to the visitor’s needs. This keeps the conversation going and helps them take the next step without confusion.

    4. Speaks your brand

    You can customize your AI voice agent to match your brand's specific tone, style, and values. You can choose from multiple male and female voices and adjust how formal the AI agent sounds. This way, the AI agent maintains consistency and delivers a memorable experience across every interaction. This is more important now because 76% of customers expect consistent interactions.

    5. Achieves your business goals

    An AI voice agent doesn't just talk. It achieves your most important goals while engaging visitors in conversations. For example, it can:

  • Qualify visitors
  • Book more meetings
  • Capture contact details
  • Nurture prospects who aren’t ready to buy
  • Each conversation moves toward a specific goal.

    6. Speaks multiple languages

    An AI voice agent can speak multiple languages fluently. It can automatically detect and switch to the visitor's preferred language without any manual setup. 

    This means your global audience feels understood and valued. They can connect with your brand without any language barriers. And you expand your reach and increase conversions without hiring multilingual sales and support teams.

    How to create a voice AI agent for your B2B website

    Now, let’s learn how you can create a smart AI voice agent for your website using Expertise AI. The setup is so simple that you can complete it in minutes without any technical knowledge. 

    1. Train your AI agent

    The first step is to teach your AI agent about your business. Here's how to do it:

  • Log in to Expertise AI
  • Go to the Training Materials tab
  • Add your website URL and click Fetch URL
  • Select the pages you want the agent to learn from
  • And then click Train Selected URLs
  • Make sure these pages clearly explain your products, pricing, and use cases. The AI will extract this information and use it to answer visitor questions accurately. You can also train the agent using documents, sitemaps, and plain text.

    Now, go to the Voice AI tab and follow the steps below.

    2. Set a welcome message

    This is the first sentence your AI agent speaks when a voice conversation starts.

    A good welcome message greets visitors and encourages them to speak. You can make it casual or professional based on your brand image.

    Here is an example: “Hi! This is Chris from Clay. How can I help you today?”

    3. Set its voice and personality

    In this step, you will define how your AI agent should behave. You can do this by simply writing a prompt that explains the agent’s tone, personality, and goal. You can tell it how to respond and what to prioritize during conversations.

    You can also choose the voice, accent, and speaking style. Expertise AI supports multiple voices, including English and Australian accents. You can preview them before selecting one.

    4. Customize incoming call

    This step lets you control when and where the voice agent appears. For example, you can:

  • Set the time delay before the voice bar pops up
  • Choose which pages should show the voice agent
  • Hide the voice bar from specific URLs
  • This helps you show the voice agent only on high-intent pages like pricing or product pages at the right time.

    5. Set a call goal

    Here, you choose what the AI should achieve during the call:

  • Book a meeting
  • Capture contact details
  • Provide general assistance
  • For example, if your goal is meeting booking, simply provide your calendar link. And the AI will guide visitors naturally toward the action.

    6. Test and deploy

    Before making your AI agent live, test everything. 

    You can do this in the Try My AI tab. Ask questions and see how the AI agent responds. If you don’t like a particular response, you can refine it in the Conversations tab. You can also adjust the agent’s personality and style as discussed above.

    Once you are satisfied, deploy your AI agent to your website. Just copy the code snippet from the Dashboard and add it to your website’s HTML file. That’s it.

    Summing up

    AI voice agents are turning B2B websites into two-way conversation channels. By letting visitors simply speak instead of type, you make it easier for buyers to engage with your site and take the next steps.

    For instance, Expertise AI recently launched Voice AI 2.0. The AI understands intent, responds faster, and handles interruptions more smoothly to deliver more natural conversations. It can answer complex queries, qualify needs, and capture high-intent leads so you never miss a sales opportunity.
