About This Project
Sonora is a private, fully offline speech studio for Windows that offers text-to-speech, speech-to-text, and global dictation.
Tech Stack
Overview
I built Sonora, a Windows desktop app that lets you create and transcribe speech entirely offline. It combines text-to-speech, speech-to-text, and global voice typing into one local studio.
Challenge
Many speech tools send your data to the cloud, risking privacy and requiring internet. I wanted to keep everything on your PC with no external servers involved.
What I shipped
- A native app with a sleek studio UI for managing voices and dictation
- Global dictation that types into any app using a hotkey and live streaming
- First-run setup that installs a private Python runtime and downloads speech models
- Local multi-engine speech processing with offline TTS and STT
- Automatic signed updates and a public landing site to showcase the product
Result
Sonora lets users work with speech privately and securely on Windows. It supports natural voice creation, transcription, and dictation without cloud dependencies.
