Artificial intelligence is an umbrella term covering a range of technologies and applications. For business decision-makers, it’s useful to break down the types of AI being deployed because each offers unique capabilities and benefits. AI can also be categorized based on agent types, with each agent type having key features, roles and levels of autonomy that define how they operate and interact within different environments. One particular subset of AI that is emerging as especially crucial is voice AI.
Here are some of the key AI categories making waves — often working in tandem — along with real-world use cases in the aforementioned verticals:
1. Chatbots, Conversational AI and Natural Language Processing
These technologies are the text-based cousins of voice assistants (i.e., the chat bubbles on websites or messaging apps that can answer questions and help customers). Powered by AI language models, modern chatbots can handle a surprising range of inquiries.
A hospital’s website chatbot might help a patient find a clinic location or triage symptoms, much like a human assistant. Some restaurants use chatbots on their website or Facebook to take orders or reservations and answer common inquiries, whereas automotive dealers deploy these AI tools to qualify sales leads before a human salesperson steps in.
What makes today’s chatbots different from the clunky, scripted bots of a few years ago is their capability to understand natural language and context much better because of advances in AI. They’re essentially available 24/7, offer consistent answers and are infinitely scalable, allowing human employees to focus on more complex, high-value interactions.
2. Voice AI and Virtual Agents
Voice AI refers to systems that can engage in spoken conversation with people. Think of voice assistants like Siri, Alexa or Google Assistant. It also encompasses specialized voice agents for businesses (i.e., virtual receptionists).
Voice AI is particularly relevant in sectors where customers rely heavily on phone calls or voice interfaces. Examples include scheduling a doctor’s appointment, making a restaurant reservation or getting directions using your vehicle’s voice command.
Voice interaction is becoming so common that it’s on track to be as fundamental to business as having a website was in the early 2000s. Customers are beginning to expect that they can speak to your company, not just click or type. Millions of consumers use voice assistants, and voice searches are a regular part of shopping and information inquiries. One survey found that 44% of consumers have used voice search to inquire about car prices.
Voice AI for business can take multiple forms, such as:
- An AI agent that answers your service hotline
- An AI agent that confirms appointments with patients via phone
- In-vehicle voice systems that allow drivers to ask for support without taking their hands off the wheel.
The future of AI in voice is likely to make interactions even more seamless. Recent advancements now enable voice assistants to complete complex tasks, such as making purchases, managing smart home routines or providing detailed, personalized responses.
Many customers won’t even notice whether they’re interacting with a human or an AI agent — as long as their needs are met quickly. Just as every business eventually needed a user-friendly website, we’re approaching a time when every business will need a strategy for user-friendly voice AI engagement.
3. Generative AI
This refers to AI systems that create new content (i.e., text, images, audio, video) based on patterns learned. ChatGPT, which can generate essays or answer questions, is a text example, whereas DALL-E creating images from descriptions is a visual one.
Generative AI opens up numerous possibilities for businesses of all types and sizes. In marketing, the technology can be utilized to draft social media posts, product descriptions or ad slogans to be optimized by humans. Examples of generative AI using the verticals previously listed in this article include:
- A restaurant chain creating flavorful menu item descriptions or localized ad copy
- An automotive company generating personalized email follow-ups for customers
- Home service companies quickly generating for customers a summary of work performed
- Healthcare providers drafting patient visit summaries or health recommendations based on a patient’s condition
Generative AI won’t replace your marketing team or technical writers, but it can help them produce content faster. The technology is even AI used for coding; it assists software developers by suggesting code, similar to how early internet open-source libraries accelerated development. The key for businesses is to integrate generative AI strategically and with human oversight to boost creativity and efficiency.
4. Agentic AI (Autonomous Agents)
A newer, emerging category, agentic AI refers to artificial intelligence systems that can take initiative and autonomously perform multi-step tasks. AI agents work by having defined roles, personalities and communication styles, along with specific instructions and available tools to perform their tasks. Unlike a chatbot or voice bot that responds when spoken to, this technology tool might be given a high-level goal and figure out how to achieve it by interacting with multiple systems.
Think of it as an AI agent that could automatically handle your company’s invoice processing from start to finish. It receives an email with an invoice, reads it, enters it into the accounting system, schedules a payment and sends a confirmation — all without human intervention. These systems can also integrate with external tools to gather data and enhance their problem-solving capabilities.
Consumers could use agentic AI to book a vacation based on specific parameters. The AI tool would search flights and hotels and make reservations based on those preferences.
In our focus industries, agentic AI could soon help with supply chain and logistics. An AI agent in a restaurant could monitor inventory levels and automatically place orders with suppliers when stock runs low — even negotiate prices or delivery times according to rules set by managers. In home services, an AI agent might coordinate an entire project, from ordering parts to scheduling the right technicians and updating the customer. Agentic AI can handle complex tasks and solve multi step problems by analyzing diverse data sources and developing strategies to execute intricate workflows.
Though still somewhat premature, this type of AI has the potential to handle complex workflows that typically require a lot of back-and-forth. As businesses document their processes digitally, agentic AI can leverage that to execute processes, dramatically improving productivity by automating repetitive multi-step tasks.
5. Self-Driving and Robotics AI
A prime example of this type of AI that can perceive and act in the physical world is self-driving cars. These vehicles use AI models to interpret camera and sensor data and drive safely. Autonomous vehicles are already providing taxi services in select cities and handling warehouse deliveries in controlled environments.
Beyond automobiles, examples of this category of AI consists of delivery drones, warehouse robots or autonomous checkout in retail stores. In healthcare, robotics with AI assist in surgeries or hospital logistics. Some hospitals employ robotic carts that navigate hallways to deliver medications.
For businesses, adopting this type of AI can mean physical automation. A restaurant might use an automated kitchen assistant that uses computer vision to monitor cooking, while a home services company might fly a drone to inspect a roof instead of risking a technician on a ladder.
Businesses should keep an eye on how these advancements have the potential to open up new service models. AI comes in many forms, and forward-thinking businesses are experimenting with different types to see where each can add value to transform their operations.
