15
 
16
- ### Reading
17
-
18
- **[Netra OCR 1](https://huggingface.co/Netra-Lab/Netra-OCR)** reads printed Khmer and English. A 19M-parameter text-line recognizer trained only on synthetic images, it has a 0.96% character error rate on the KHOB benchmark, against 5.12% for Tesseract 5. It comes with line and layout detection, PDF input and an editor that runs in the browser.<br>

- ### Translation
22
-
23
- **[Netra MT 1](https://huggingface.co/Netra-Lab/Netra-NMT)** translates English↔Khmer, both directions in one 77M-parameter model trained from scratch on 220M tokens. On English→Khmer it scores 25.8 spBLEU on ALT, second only to Google Translate and ahead of NLLB-200 1.3B. On Khmer→English it still trails the larger models. About 40 ms per sentence on a desktop CPU.<br>

- ### Speech
27
-
28
- **Sota** transcribes Khmer and English speech, in two sizes pruned from Meta's 975M-parameter Omnilingual ASR. The 204M model has a 1.77% character error rate on the DDD Khmer test set, below its teacher's 2.47%, at a quarter of the compute.<br>

31
- ### Typing
32
-
33
- **AkaraAlpha** turns Khmer typed in the Latin alphabet back into Khmer script. With 78.7K parameters, it has a lower character error rate than a Transformer three times its size, and with a dictionary check its first suggestion is right 74% of the time.<br>
