AI Transcription Glossary
The definitive reference for AI audio intelligence, speech recognition, and real-time transcription technology. Every term explained with how CoScript implements it natively.
Core Technology
Speech-to-Text (STT)
The process of converting spoken language into written text using AI-powered recognition algorithms.
Real-Time Transcription
The ability to convert speech into text instantaneously as words are spoken, with minimal latency.
Voice Recognition
AI technology that identifies and processes human speech patterns to understand spoken words.
Natural Language Processing (NLP)
A branch of AI focused on enabling machines to understand, interpret, and generate human language.
Large Language Models (LLMs)
Massive AI models trained on vast text corpora that can understand, generate, and reason about natural language.
Accent Adaptation
The ability of speech recognition systems to accurately transcribe speakers with diverse accents and dialects.
Offline Transcription
The ability to convert speech to text natively on a local device without requiring an active internet connection.
Word Error Rate (WER)
The standard metric used to measure the accuracy of speech recognition systems.
Continuous Dictation
The ability to speak naturally for extended periods of time without the speech recognition system timing out or requiring manual restarts.
Advanced Features
Speaker Diarization
The process of identifying and separating different speakers within a multi-person audio recording.
Audio Intelligence
AI-powered analysis of audio content to extract meaning, emotion, and structured data from speech.
Machine Translation
Automated translation of text between languages using AI models trained on parallel corpora.
Sentiment Analysis
AI technique that determines the emotional tone and attitude expressed in text or speech.
Use Cases
Meeting Transcription
Automated conversion of meeting audio into structured written notes, often with speaker labels and timestamps.
Live Captioning
Real-time generation of text captions overlaid on video or audio streams for accessibility and comprehension.
AI Note-Taking
Automated capture and organization of meeting notes using artificial intelligence.
Cloud-Free Transcription
The process of generating text from audio without transmitting any data over the internet to remote servers.
Automated Meeting Summary
An AI-generated distillation of a long meeting transcript into concise notes, key decisions, and actionable tasks.
Technical Architecture
WASAPI Loopback
A Windows audio interface that captures all system audio output directly from the sound card without microphone input.
Edge Computing
Processing data at the network edge, closer to the user, reducing latency and bandwidth requirements.
Local LLM
A Large Language Model that is downloaded and executed entirely on a user's local hardware rather than a cloud server.
Voice Activity Detection (VAD)
An algorithm that detects the presence or absence of human speech in an audio signal.
Acoustic Model
The component of a speech recognition system that represents the relationship between an audio signal and the phonetic units of speech.
Audio Latency
The delay between when a word is spoken and when it appears as text on the screen.
Security & Compliance
HIPAA Compliant Transcription
Medical transcription that meets the strict data privacy and security requirements of the Health Insurance Portability and Accountability Act.
SOC2 Compliance
A voluntary compliance standard for service organizations that specifies how organizations should manage customer data.
Zero-Trust Architecture
A cybersecurity framework that requires all users, whether inside or outside the organization's network, to be authenticated, authorized, and continuously validated.
Privacy-First AI
Artificial intelligence systems engineered from the ground up to minimize data collection and maximize user data sovereignty.
Data Localization
The practice of keeping data within the borders of a specific country or entirely on a local device to comply with local privacy laws.
