Text-to-Speech
Text-to-speech (TTS) is the AI technology that converts written text into natural-sounding spoken audio. Modern TTS systems produce remarkably human-like voices with appropriate prosody and emotion.
Understanding Text-to-Speech
Text-to-speech synthesis converts written text into natural-sounding spoken audio, enabling machines to communicate through voice. Modern TTS systems use deep learning architectures like Tacotron, WaveNet, and VITS to produce remarkably human-like speech with appropriate prosody, intonation, and emotional expression. These generative models have replaced older concatenative and parametric approaches, achieving quality that is increasingly indistinguishable from human recordings. Text-to-speech powers virtual assistants, audiobook narration, accessibility tools for visually impaired users, navigation systems, and customer service interfaces. Recent advances include zero-shot voice cloning that can replicate a speaker's voice from a brief sample, raising important responsible AI concerns about deepfake audio and consent. The technology is closely related to natural language processing for text understanding, and watermarking techniques are being developed to identify AI-generated speech and prevent misuse in fraud or disinformation campaigns.

Agent
An AI agent is an autonomous system that perceives its environment, makes decisions, and takes actions to achieve specific goals. Modern AI agents can use tools, browse the web, write code, and chain multiple reasoning steps together.
Agentic AI
Agentic AI refers to AI systems that can autonomously plan, reason, and execute multi-step tasks with minimal human oversight. These systems use tool calling, memory, and iterative problem-solving to accomplish complex goals.
AI Visibility
AI visibility refers to how prominently a brand, product, or entity appears in AI-generated responses from systems like ChatGPT, Perplexity, and Gemini. As AI-powered search grows, visibility in AI recommendations becomes a critical marketing metric.
Chatbot
A chatbot is a software application that simulates human conversation through text or voice interactions. Modern AI chatbots use large language models to generate contextually relevant, natural-sounding responses.
Hate Speech Detection
Hate speech detection is the AI task of automatically identifying harmful, abusive, or discriminatory language in text. It is a key component of content moderation systems on social media platforms.
Human-in-the-Loop
Human-in-the-loop (HITL) is an approach where humans actively participate in the AI decision-making or training process. HITL systems combine human judgment with AI speed to improve accuracy and safety.
Information Retrieval
Information retrieval is the science of searching and extracting relevant documents or data from large collections. Modern AI-powered search uses embeddings and language models to understand semantic meaning.
Intelligent Agent
An intelligent agent is an autonomous entity that observes its environment through sensors and acts upon it through actuators to achieve goals. Modern AI agents combine perception, reasoning, and action in complex workflows.
