Key Features

Real-time Speech Recognition

High-quality speech-to-text transcription using Facebook's Wav2Vec2 model with sub-second latency for production environments.

Hardware Acceleration

Optimized for CUDA, Metal Performance Shaders, and CPU with automatic device detection and intelligent resource management.

Multiprocess Architecture

Process isolation prevents UI freezing during ML operations with automatic recovery mechanisms and fault tolerance.

WebSocket Communication

Real-time bidirectional communication between frontend and backend with automatic reconnection and message queuing.

Audio Device Management

Comprehensive audio device selection, testing, and monitoring with visual feedback and automatic configuration.

Persistent Storage

Automatic transcription history management with configurable storage options and intelligent cleanup policies.
