### a

**AI (Artificial Intelligence)**  
The simulation of human intelligence in machines that can learn, reason, and adapt to new information or situations.

**API (Application Programming Interface)**  
A set of rules that allows different software systems to communicate and share data with each other.

**Assets**  
Characters, scripts, media, and other creative resources created within a Workspace. Assets are shared with all collaborators in that Workspace and can be shared via the Public Library.

**Avatar**  
A digital, animated character that represents a person or brand in virtual environments, training, or customer interactions.

**AWS (Amazon Web Services)**  
A leading cloud computing platform that provides scalable infrastructure, storage, AI services, and developer tools.

### b

**Body Animation**  
The movement and gestures of a digital avatar that bring it to life and create realistic interactions.

### c

**ChatGPT (OpenAI)**  
A conversational AI model developed by OpenAI that generates human-like text responses based on prompts.

### d

**Digital Character**  
A computer-generated persona, often stylized or branded, designed for storytelling, training, or interactive experiences.

**Digital Human**  
A highly realistic, AI-powered avatar designed to look, move, and respond like a real person.

**Digital Twin**  
A virtual representation of a real-world person, process, or system that mirrors its behaviors and characteristics for training, analysis, or simulation.

**Durable Skills**  
Essential human skills such as communication, leadership, and empathy that remain valuable across industries and roles.

### e

**Embodied AI**  
Artificial intelligence presented in a digital body (such as an avatar) capable of speech, movement, and expression.

### f

**Facial Animation**  
Technology that captures or generates expressions to give avatars lifelike emotional responses.

**Feedback Loop**  
A system where performance data or user responses are collected and used to improve future interactions or training.

### g

**Gemini (Google DeepMind)**  
Google DeepMind’s family of large language models (LLMs) designed for advanced reasoning, problem-solving, and multimodal AI tasks.

**Generative AI**  
A type of AI that can create new content, such as text, images, video, or speech, based on prompts.

**Groq**  
A hardware company specializing in ultra-fast AI inference processors designed for speed and scalability.

### l

**L&D (Learning and Development)**  
The organizational function that manages employee training, skill development, and professional growth.

**Latency**  
The time it takes for a system to respond to a user’s action. In the context of avatars and interactive experiences, it’s the delay between input (like speech, text, or motion) and the avatar’s real-time response.

### m

**Machine Learning (ML)**  
A branch of AI where algorithms improve their performance over time by learning from data.

**MetaHumans (Epic Games)**  
Ultra-realistic, customizable digital characters created with Epic Games’ Unreal Engine, widely used in film, games, and interactive experiences.

### n

**Natural Language Processing (NLP)**  
The field of AI that enables computers to understand, interpret, and respond to human language.

**No-Code**  
Software that allows users to build and customize applications or experiences without writing code.

### o

**Organization**  
Your company or team’s home base in Rapport. It’s where you manage subscriptions, billing, and user access. An Organization can host multiple Workspaces and allows team-wide collaboration based on permissions.

### p

**Personalization**  
Customizing content, training, or customer interactions to match individual preferences, roles, or behaviors.

**Projects**  
Core interactive experiences built in Rapport. Projects live inside Workspaces and combine character design, AI settings, templates, and deployment methods.

**Prompt**  
The instruction or input provided to an AI system to generate a specific output.

**Prompt Engineering**  
The practice of designing and refining prompts to achieve better, more accurate AI responses.

**Push-to-Talk (PTT)**  
This allows users to initiate voice transmission by pressing a designated button or key, instead of continuously broadcasting audio. The user is required to activate the microphone only when they want to speak.

### r

**Rapport Session Runners**  
Cloud-based (or on-premise) servers that execute live user sessions and handle real-time character interactions.

**Rapport Studio**  
A web-based interface where users create, configure, and design interactive projects, characters, and experiences.

**Ready Player Me (Wolf3D)**  
A cross-platform avatar creator that lets users design a customizable 3D character.

**Real-Time Rendering**  
Technology that generates visuals instantly, enabling avatars and virtual environments to respond live.

**Retrieval-augmented generation (RAG)**  
A powerful tool that equips large language models (LLMs) with the ability to access real-world data for more informed responses.

**Role-Play Simulation**  
A training method where learners practice conversations and scenarios with avatars in a safe, controlled environment.

### s

**Sales Training**  
The process of teaching sales teams the skills, knowledge, and techniques needed to engage customers and close deals.

**Scenario Builder**  
A tool for creating customized situations and conversations to train employees or simulate customer interactions.

**Speech-to-Text (STT)**  
Technology that converts spoken language into written text for transcription or real-time applications.

### t

**Text-to-Speech (TTS)**  
Technology that converts written text into natural-sounding spoken voice.

### u

**Unity (Unity Technologies)**  
A popular 3D development platform used to create real-time interactive content.

**Unreal Engine (Epic Games)**  
A powerful real-time 3D engine widely used for gaming, film, simulation, and virtual production.

### w

**Workspace**  
Your creative studio within Rapport where projects and assets live. Workspaces organize collaboration, access control, and share creative resources.
