Lyro — Real-Time Voice Typing Engine for Faster Everyday Productivity
Algofolks partnered with Lyro to develop a cross-platform voice-to-text engine that types into any application instantly. The system delivers low-latency speech recognition, local privacy, and a seamless typing experience optimized for professionals, writers, developers, and creators.
Client Overview
Lyro set out to build an AI-powered typing assistant that converts speech into text across any app, on any platform. Their goal was simple: enable users to type instantly using their voice — without lag, without cloud dependency, and without privacy concerns.
The product needed to work universally across Windows, Linux, and macOS, and feel “invisible” inside the user’s existing workflow.
The Challenge
Before Algofolks, the client faced several limitations:
Before: Manual & Slow
- Existing STT tools were slow, laggy, and often inaccurate
- Most competitors were browser-bound or restricted to specific apps
- Users reported high latency, especially in noisy environments
- Privacy-focused organizations required zero cloud audio storage
- Cross-platform compatibility was complex and fragile
- Real-time injection into ANY editable app required native OS-level engineering
To succeed, Lyro needed a custom-built, low-latency, privacy-first speech pipeline that could run consistently across all major OS environments.
What Algofolks Built (Full Platform Breakdown)
Algofolks engineered Lyro from scratch, delivering:
Cross-Platform Desktop Application
Built using a hybrid native + Electron architecture with:
- Real-time mic capture
- Multi-language IME handling
- System-tray controls
- Universal hotkey activation
- Seamless text injection across ANY app
Outcome :
Smooth, OS-native typing behavior with minimal CPU usage.
Real-Time Speech Pipeline
A fully custom audio-to-text engine with:
- Streaming token-based recognition
- Local noise suppression
- Whisper/Hybrid STT model optimization
- Offline fallback mode
- Adaptive latency throttling
Outcome :
Typing feels instantaneous, even in long dictation sessions.
Privacy & Security Architecture
To meet enterprise and privacy-sensitive use cases:
- No audio logging or cloud retention
- Local encryption for transcript history
- Strict sandbox permissions
- Zero third-party analytics on voice data
Outcome :
A voice assistant safe enough for legal, medical, and enterprise teams.
Transcript History & Local Search
Users can:
- Store transcripts locally
- Replay or reuse dictation
- Search across sessions
- Tag notes automatically
Outcome :
Improves workflow, organization, and knowledge recall.
Auto-Updater + Release Pipeline
Algofolks built:
- Differential updates
- Version rollback safety
- Crash diagnostics (privacy-safe)
- Segmented release channels (stable/beta)
Outcome :
Lyro updates itself quietly, without breaking user workflow.
Results & Impact
Lyro saw immediate and measurable improvements:
| Metric | Impact |
|---|---|
| Ultra-low latency for real-time dictation | Typing responds nearly instantly to speech. |
| Higher accuracy in noisy environments | Noise filters improved accuracy for remote workers and creators. |
| 3× increase in daily active students | Platform scales smoothly during exams |
| Reliable cross-platform releases | One codebase powering Windows, Linux, and macOS. |
| Strong user adoption | Daily usage rose consistently as the system stabilized. |
| Private-by-design speech assistant | Enterprise clients loved the local-only processing model. |
