Sherpa Voice vs Haptic Studio Lab

Sherpa Voice is an open-source demo app that showcases what on-device speech and audio AI can do — directly on your phone, with no cloud and no internet required. Whether you are a developer evaluating libraries for your next app, a researcher exploring mobile inference, or just curious about offline AI, Sherpa Voice lets you try 10 speech and audio features hands-on. WHAT YOU CAN TRY - Speech Recognition: Transcribe speech to text from files or live microphone input. Multiple languages supported. - Text-to-Speech: Generate natural-sounding speech from text with various voices and speakers. - Voice Activity Detection: Detect speech vs silence in real-time audio. - Keyword Spotting: Listen for custom keywords without full transcription. - Speaker Identification: Recognize speakers by their voice. - Speaker Diarization: Figure out who spoke when in a conversation. - Audio Tagging: Classify sounds — music, speech, environmental noise. - Language Identification: Detect which language is being spoken. - Speech Enhancement: Remove background noise from recordings. - Punctuation: Add punctuation to raw transcripts. Each feature comes with a downloadable model catalog so you can compare different models for speed, size, and accuracy. FOR DEVELOPERS Sherpa Voice is built with React Native and Expo using two open-source libraries: - sherpa-onnx: C++ inference engine for speech models, with mobile-optimized ONNX Runtime - expo-audio-stream: Real-time audio recording, analysis, and visualization for React Native Everything you see in this app can be integrated into your own project. The full source code is available on GitHub — use it as a reference, fork it, or contribute. HOW IT WORKS 1. Pick a feature (Speech Recognition, TTS, etc.) 2. Download a model from the built-in catalog (one-time, typically 15-100 MB) 3. Use the feature — all processing runs locally on your device PRIVACY No accounts. No tracking. No data collection. Audio never leaves your device.

HapticLab is a haptics research app for creating, comparing, and feeling tactile feedback in UI and games. Choose from impact, notification, selection, and custom templates, then adjust intensity and duration as you play them. In the custom editor, place Tap and Hold events on a timeline and fine-tune strength, sharpness, duration, and curves. In the Lab, assign haptics to real interactions such as buttons, counters, toggles, tabs, sliders, result notifications, scratch cards, tracing, and hold confirmations. In Puchi Link, you can test tracing, linking, and clearing feedback inside a small puzzle game. HapticLab Pro unlocks saving custom haptics, export, import, additional templates, saved-haptic assignments, Pro-only lab samples, and puzzle play. Actual vibration requires a supported iPhone. Haptics cannot be felt in the simulator.
