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. ## Sherpa Voice Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/3a/2f/48/3a2f48e6-a6ee-4a09-a76a-22310c024d57/01-features.png/1284x2778.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/34/80/df/3480dfcc-8110-2677-2db3-718e6bf4db78/02-models.png/1284x2778.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/94/63/42/94634265-cca4-8ad6-33ed-1b9741c27909/03-about.png/1284x2778.png) ## Sherpa Voice Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Free | Romania | Developer Tools | #107 | ## Apps Similar to Sherpa Voice - [SymbolGrid](https://apptail.io/app/symbolgrid-zqsj/bulgaria) - [VoiceOver Designer](https://apptail.io/app/voiceover-designer-SVWk/bulgaria) - [Monitor OSC](https://apptail.io/app/monitor-osc-KAYp/bulgaria) - [YAME](https://apptail.io/app/yame-IVBv/bulgaria) - [QuickPort Terminal](https://apptail.io/app/quickport-terminal-HXgy/bulgaria) - [Script: JS & TS Editor](https://apptail.io/app/script-js-ts-editor-wooy/bulgaria) - [Mosh Terminal](https://apptail.io/app/mosh-terminal-PrXy/bulgaria) - [NetScanner - HTTP Catcher](https://apptail.io/app/netscanner-http-catcher-wwZy/bulgaria) - [Deviap](https://apptail.io/app/deviap-padz/bulgaria) - [Regex Playground](https://apptail.io/app/regex-playground-Qpzz/bulgaria) ## Sherpa Voice Available In - [Armenia](https://apptail.io/app/sherpa-voice-agWy/armenia) - [Bulgaria](https://apptail.io/app/sherpa-voice-agWy/bulgaria) - [Canada](https://apptail.io/app/sherpa-voice-agWy/canada) - [Chile](https://apptail.io/app/sherpa-voice-agWy/chile) - [Dominican Republic](https://apptail.io/app/sherpa-voice-agWy/dominican-republic) - [Ireland](https://apptail.io/app/sherpa-voice-agWy/ireland) - [India](https://apptail.io/app/sherpa-voice-agWy/india) - [Iceland](https://apptail.io/app/sherpa-voice-agWy/iceland) - [Japan](https://apptail.io/app/sherpa-voice-agWy/japan) - [South Korea](https://apptail.io/app/sherpa-voice-agWy/south-korea) - [Kuwait](https://apptail.io/app/sherpa-voice-agWy/kuwait) - [Latvia](https://apptail.io/app/sherpa-voice-agWy/latvia) - [Mexico](https://apptail.io/app/sherpa-voice-agWy/mexico) - [Malaysia](https://apptail.io/app/sherpa-voice-agWy/malaysia) - [Nepal](https://apptail.io/app/sherpa-voice-agWy/nepal) - [Peru](https://apptail.io/app/sherpa-voice-agWy/peru) - [Poland](https://apptail.io/app/sherpa-voice-agWy/poland) - [United States](https://apptail.io/app/sherpa-voice-agWy/united-states) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
