AF Speech: Offline Speech-to-Text AI Desktop App

AF Speech is a Windows desktop application designed to eliminate manual typing completely, allowing users to write anywhere simply by speaking.

The project was born from a real and common problem: most speech‑to‑text tools available today require monthly subscriptions, constant internet connection, and the transmission of audio data to external servers — resulting in higher costs, latency, and serious privacy concerns.

AF Speech completely reverses this approach by leveraging the local power of the user’s PC, especially CPU and NVIDIA GPU, to run artificial intelligence entirely offline.

AF Speech is an intelligent dictation system that converts voice into text using advanced AI models executed entirely on the local machine.

Users can dictate text inside any application — browser, editor, CRM, chat, documents — through a global hotkey, without interrupting their workflow.

The application runs silently in the Windows system tray, includes a visual listening overlay, and features intelligent GPU resource management.

Why this project delivers real value

💰 Zero recurring costs

Unlike cloud‑based solutions:

• no per‑minute fees

• no subscriptions

• no external APIs

Once installed, the application uses hardware the user already owns, effectively turning the GPU into a personal AI accelerator.

🔒 Total privacy (100% offline)

All processing happens locally:

• no audio is sent online

• no servers involved

• no remote logging

Voice data never leaves the user’s computer, making AF Speech ideal for professional, business, and privacy‑sensitive environments.

⚡ High performance

Thanks to CUDA acceleration:

• fast transcription even with large AI models

• minimal latency

• optimized VRAM usage

The experience remains smooth even when using powerful models such as Whisper Large‑v3.
