## 🚀 Overview
This repository aims to share and develop the most efficient speech-to-text and text-to-speech inference solution -with a strong focus on self-hosting, cloud hosting, and on-device inference across multiple devices.
For the first release this repository provides **open-source transcription models** with **streaming inference support** and:
- Hugging Face open weights for whisper models with a flexible chunk size (original models have 30s)
- High-performance TheStage AI inference engines (NVIDIA GPU), 220 tok/s on L40s for whisper-large-v3 model
- CoreML engines for macOS / Apple Silicon with the lowest in the world power consumption for MacOS
- Local RestAPI with frontend examples using JS and Electron [see for details](electron_app/README.md)
- Electron demo app built by TheStage AI (Certified by Apple): [TheNotes for macOS](https://cdn.thestage.ai/production/cms_file_upload/1761746543-88b5430a-5897-4348-b031-8a1101352c72/The%20Notes.pkg)
- [Tutorial](https://app.thestage.ai/blog/Building-a-macOS-Note-Taker-app-on-Electron-with-TheWhisper?id=6) on building local note-taking app for macOS using Electron and TheWhisper
https://github.com/user-attachments/assets/f4d3fe7b-e2c5-42ff-a5d0-fef6afd11684
It is optimized for **low-latency**, **low power usage**, and **scalable** streaming transcription. Ideal for real-time captioning, live meetings, voice interfaces, and edge deployments.

from thestage_speechkit.apple import ASRPipeline
model = ASRPipeline(
model='TheStageAI/thewhisper-large-v3-turbo',
# optimized model with ANNA
model_size='S',

## 💻 Build On-Device Desktop Application for Apple
You can build a macOS desktop app with real-time transcription. Find a simple ReactJS application here: **Link to React Frontend**
You can also download our app built using this backend here: [TheNotes for macOS](https://cdn.thestage.ai/production/cms_file_upload/1761693601-8ef0605f-a2e0-4bef-97c1-b61452e4f7dc/The%20Notes%20Package%20Oct%2028%202025.pkg)
-----
## 📊 Benchmarks
TheWhisper is a fine-tuned Whisper model that can process audio chunks of any size up to 30 seconds. Unlike the original Whisper models, it doesn't require padding audio with silence to reach 30 seconds. For quality benchmarks, we used the multilingual benchmarks [Open ASR Leaderboard](https://github.com/huggingface/open_asr_leaderboard#evaluate-a-model).
For comprehensive quality and performance benchmarks, including comparisons with other Whisper inference solutions, please refer to the [benchmark/](benchmark/README.md) directory.
