AI Voice Agents have changed how we use technology by making everyday tasks like ordering pizza or booking flight reservations more straightforward and natural through speech. 

Picture an assistant who can handle your calls, respond intelligently to your questions, manage your schedule, and work tirelessly around the clock—all without requiring a coffee break.

But what exactly is an AI Voice Agent? It is an autonomous system that combines speech technologies like text-to-speech (TTS) and speech-to-text (STT) with advanced reasoning capabilities powered by large language models (LLMs). 

Unlike traditional virtual assistants (e.g., Siri), AI Voice Agents are great at processing natural language, generating human-like responses, and performing multi-step, complex tasks that range from scheduling appointments to booking flights, managing hotel reservations, and interacting with customers.

In this technical deep dive, you will learn:

• How large language models (LLMs) underpin AI Voice Agents by enabling nuanced understanding and response generation.

• The role of STT and TTS technologies in converting speech to digital text and vice versa with remarkable accuracy.

• Real-world applications of AI Voice Agents in industries like customer service, healthcare, and accessibility solutions.

Let us look at how voice-based AI agents are changing how humans and machines interact. 🚀

🤖 What is an AI Agent?

The book Artificial Intelligence: A Modern Approach defines an AI agent as:

"Anything that can be viewed as perceiving its environment through sensors and acting upon that environment through actuators."

In simpler terms, an AI agent is an autonomous system that:

1. Perceives its environment through sensors (e.g., a microphone for audio input).

2. Acts on the environment using actuators (e.g., generating speech output).

3. Continuously improves its actions based on feedback (reward for successfully advancing the goal or penalty for not).

For Voice AI agents, this perception involves processing speech input through Speech-to-Text (STT) systems, reasoning through natural language models (LLMs), and acting by generating human-like speech through Text-to-Speech (TTS) technology.

🧠 Types of AI Agents: How Do They Think and Act?

AI agents can be categorized into several types based on their decision-making approach and adaptability to complex environments. Below are the main categories and how they apply to Voice AI.

⚡ Simple Reflex Agents: Reactive Decision Makers

Simple reflex agents act based on predefined rules (if-then statements). They work well in simple scenarios where all information is observable but cannot remember past states.

• Example: A smart home assistant turning off lights when the user says, "Turn off the lights."

• Key tech: ASR (Speech-to-Text) processes the command, and predefined logic executes the action.

🗺️ Model-Based Reflex Agents: Reasoning with Environmental Models

Model-based reflex agents improve upon simple agents by maintaining an internal model of the environment. This allows them to track state changes over time and handle incomplete or partially observable scenarios.

• Example: A navigation system that dynamically adjusts directions based on real-time voice commands like "Find a faster route." It recognizes the user’s intent and remembers prior queries during a multi-turn conversation to maintain context.

• Key tech: Natural Language Processing (NLP) and dialogue context tracking.

🎯 Goal-Based Agents: Focused on Objectives

These agents select actions that bring them closer to defined goals, often requiring reasoning and planning to determine the best path to success.

• Example: An AI agent managing tasks like scheduling meetings: "Set a reminder for 10 a.m. tomorrow to call John."

• Key tech: LLMs and intent-based goal tracking ensure the agent analyzes and executes the task to achieve a defined objective.

📈 Utility-Based Agents: Balancing Efficiency and Satisfaction

Utility-based agents optimize their decisions by evaluating outcomes through a utility function that measures performance. This ensures they achieve the goal and the best possible results.

• Example: A Voice AI agent optimizing speech output for clarity and speed during navigation instructions.

• Key tech: Real-time latency optimization and TTS prosody adjustments.

🔄 Learning Agents: Adaptive and Evolving Systems

Learning agents improve performance over-time by analyzing environmental interaction feedback (rewards/penalties). This adaptability makes them ideal for dynamic or unpredictable scenarios.

• Example: An AI agent using a reinforcement learning policy to improve speech accuracy based on user feedback (e.g., detecting and correcting mispronunciations).

• Key tech: Reinforcement learning from human feedback (RLHF) or direct policy optimization (DPO) and continual model fine-tuning.

🧩 Large Language Models As Reasoning Engine for AI Agents

Large language models (LLMs) were originally developed for text understanding, primarily focusing on performing natural language processing (NLP) tasks such as text classification, summarization, and question answering. Initially, models like BERT required fine-tuning on specific tasks to achieve high performance.

However, researchers later discovered that LLMs could perform these tasks without fine-tuning simply by being presented with examples. This process is known as in-context learning, which demonstrates the few-shot learning capabilities of language models. This ability to follow instructions can be interpreted as reasoning.

Further research revealed that LLMs could reason effectively without prior examples, showcasing their emergent capabilities. 

These innovations proved one key insight: an LLM could serve as the core cognitive engine of an AI agent, enabling it to reason, learn, and perform tasks autonomously.

⚙️ Agentic AI Patterns

The capabilities of LLMs can be significantly enhanced by utilizing various frameworks and patterns. These strategies enable LLMs to perform more complex tasks and improve decision-making. Key patterns include:

• Chain-of-Thought

• ReAct

• ReWOO

• LLMs Equipped with Tools

• Tree of Thought

🔗 Chain-of-Thought: Structured Reasoning Process

Chain-of-Thought (CoT) involves breaking down a problem into smaller, manageable steps, enabling the model to follow a logical sequence of reasoning. 

This pattern significantly improves the model’s performance on tasks requiring detailed reasoning, such as solving math problems or answering complex questions.

For example, consider the math problem: "What is 25% of 200?" Instead of simply providing the result, Chain-of-Thought uses detailed few-shot prompts to guide the model through reasoning. The steps might include:

1. "Identify that finding 25% means calculating a quarter of the number."

2. "Convert 25% into its decimal form, which is 0.25."

3. "Multiply 0.25 by 200 to calculate the result."

The model replicates the reasoning process for similar problems by learning through these step-by-step examples, leading to more accurate and logical outcomes.

🤖 ReAct: Combining Reasoning and Action

ReAct enhances Chain-of-Thought prompting by combining reasoning with the ability to perform actions. This pattern allows models to think through problems, update their plans, and take steps like querying a database or interacting with an environment to gather more information.

For example, an agent might reason: "I need more data to answer this question," act to fetch the data, and then use the new information to refine its response.

ReAct enables models to handle complex tasks more effectively and adapt to changing needs by integrating reasoning and actions.

🛠️ LLMs Equipped with Tools: Extending Model Capabilities

The action component of ReAct primarily involves interacting with external tools, allowing the LLM to go beyond just generating text. To enable this functionality, it is essential to equip the LLM with the necessary tools to help it perform specific tasks. 

These tools can range from accessing databases and browsing the internet to interacting with other software or external systems.

Integrating these tools, the agent can gather real-time information, make decisions based on external data, and perform actions that would otherwise be impossible through text generation alone. 

This ability to select and use the right tools for a given task enhances the model's problem-solving capacity, making it more adaptive and effective in handling complex, dynamic challenges.

🔍 ReWOO (Reasoning with Open-Ended Observations): Enhancing Exploration with Reasoning

ReWOO (Reasoning with Open-Ended Observations) is a pattern designed to improve the agent's ability to handle ambiguous or complex scenarios. 

It involves continuously exploring possibilities while reasoning through each step to find the most optimal solution.

🌳 Tree-of-Thought: Hierarchical Problem Solving

A Tree-of-Thought pattern is a model that approaches problems by breaking them down into a hierarchy of interconnected ideas or subproblems. 

This structure allows the agent to explore multiple avenues of solution simultaneously and build more nuanced, comprehensive solutions.

🎙️ Extending the Capabilities of AI Agents with Voice AI Technologies (STT, TTS, LLMs, and Real-Time Processing)

Today, generative AI gets most of the attention, but Voice AI technologies are interestingly changing how humans and computers interact. 

Voice AI helps connect people and machines in ways that text-based interfaces can't. It lets software systems process spoken input and output natural speech.

When paired with advanced LLMs, Voice AI powers Voice AI Agents—systems designed to interact primarily through natural, human-like voice communication. These agents leverage four core technologies:

• Speech-to-text (STT) or speech recognition: Converts spoken words into text to process and understand user input. It is the agent's sensory component.

• Large language models (LLMs): Interpreting, reasoning, and generating responses.

• Text-to-speech (TTS) or speech synthesis: Transforms text-based responses into lifelike-sounding speech. It is the actuator component of the agent.

• Real-time processing: Facilitates seamless, back-and-forth communication between the user and the AI agent.

Let’s explore these technologies in detail.

🗣️ Speech-to-Text (STT) or Speech Recognition: Understanding Human Speech

Automatic recognition (ASR), commonly known as speech-to-text (STT), is at the heart of Voice AI. This technology translates spoken language into text by processing the audio waveform through advanced machine learning models.

1. Waveform to Spectrogram: The user’s speech is first converted into a spectrogram, a visual representation of sound frequencies over time.

2. Spectrogram to Text: The spectrogram is analyzed using models like transformers or traditional approaches like Hidden Markov Models (HMMs). The model outputs text that represents the spoken words.

This process must happen in real-time to ensure smooth interactions. Deepgram Nova-2 excels here with a Word Error Rate (WER) of just 8.4% and industry-leading inference speeds, which most developers find ideal for their projects.

Beyond reducing error rates, an ASR model must also handle real-world complexities like distinguishing speech from background noise, accurately transcribing diverse accents, and identifying multiple speakers within a conversation. Nova-2 can achieve all of these capabilities for reliable and versatile transcription.

Several open-source ASR alternatives are available, such as OpenAI's Whisper, for which we offer a fully managed version that enhances the base model with features such as built-in diarization and word-level timestamps. Other open-source ASR models include Meta's Wav2Vec and Mozilla's DeepSpeech.

On the proprietary side, notable ASR models include Rev.AI, Amazon Transcribe, AssemblyAI's Universal-2, and various transcription models from Google.

🔊 Text-to-Speech (TTS) or Speech Synthesis: Generating Human-Like Speech

Once the agent understands the user’s input, the response must be delivered naturally. Text-to-speech (TTS) systems handle this by converting textual responses into audible speech.

High-quality TTS models like Deepgram Aura, Multilingual v2 by ElevenLabs, MeloTTS, and Bark by Suno AI go beyond merely reading text. They incorporate elements like:

• Prosody: Rhythm and melody in speech.

• Intonation: Variations in pitch.

• Stress Patterns: Emphasis on specific words or syllables.

These features are essential for creating natural-sounding and engaging voices. Aura offers 12 voices and three accents, providing developers with exceptional flexibility. ElevenLabs boasts 20 voices and supports over 30 languages. Additionally, developers can create custom voices or clone existing ones for further personalization.

Bark by Suno AI can generate nonverbal sounds such as laughing, sighing, and crying, enhancing the emotional depth and realism of speech.

🎧 Audio Intelligence: Extracting Insights from Conversations

Voice AI agents don’t just hear and respond—they understand. Audio Intelligence technologies enable these agents to:

• Detect sentiment (e.g., frustration or satisfaction).

• Recognize intent (e.g., making a purchase or requesting support).

• Summarize and extract context from conversations.

Deepgram’s Audio Intelligence suite combines these capabilities to enhance user experiences. For example, summarization and sentiment analysis make interactions more intuitive, especially in customer service applications.

⚡ Real-Time Processing: Enabling Instant Communication

For a customer to communicate with an AI agent, they would need to establish a two-way communication with a server using a client application such as their phone or a web browser.

This communication has to be real-time because no matter how accurate an ASR model is, how great the reasoning ability of the LLM is, or how realistic the speech synthesis model is, the customer experience would be derailed if the communication is slow by even a couple of seconds.

That’s why real-time processing is essential for an AI agent to give a human customer the same experience they would get if they were speaking to a human agent.

The two most common communication protocols for Voice AI applications are:

• VoIP (Voice Over IP): This protocol bridges the public switched telephone network (PSTN) and the internet. It allows a regular phone to connect to a server hosting an AI agent, enabling users to call the agent and vice versa. Twilio, Vonage, and Plivo are examples of companies that provide VoIP services.

• WebRTC (Web Real-Time Communication): A standard protocol for real-time communication on the web. WebRTC enables web applications to place phone calls through the internet using IP-based phones for integration with modern web technologies. Daily.co, Agora, and SignalWire are examples of companies that offer WebRTC solutions.

🛠️ Combining Voice AI Technologies with LLMs

We have explored all the Voice AI technologies. Let’s see how combining these technologies with an LLM creates a fully functioning Voice AI agent. Imagine a scenario with a finance AI agent designed to collect customer feedback on their financial situation.

The process starts when the customer picks up their phone and places a call. Using real-time processing technology, such as Twilio API, their voice waveform is transmitted in real-time. This waveform is sent to the ASR and Audio Intelligence models. The ASR model converts the voice waveform into text, while an audio intelligence model analyzes the sentiment or intent behind the speech.

An LLM processes the audio intelligence model's transcribed text and additional context. The LLM processes this information, reasoning through the text to determine the next steps. 

For instance, if the user requests their financial history, the LLM selects a database lookup tool to retrieve the relevant information. This retrieved data is added as extra context for the LLM to generate an accurate and tailored response. This workflow exemplifies a retrieval-augmented generation (RAG).

TTS model converts text generated from the LLM into a waveform. The generated waveform is then sent back through the real-time processing service, allowing the customer to hear the agent’s response. This integration enables the customer to continue the conversation for a natural back-and-forth interaction.

🌟 Benefits of AI Agents Powered by Voice AI Technologies

AI Voice Agents offer several benefits compared to traditional AI systems that lack voice capabilities. 

Let’s see how these agents stand out from traditional AI systems, supported by progress in speech-to-text (STT), text-to-speech (TTS), and real-time processing.
