About
Khmer TTS This repository contains a Khmer text-to-speech model fine-tuned from facebook/mms-tts-khm. The model is packaged in Hugging Face Transformers format and can be loaded with VitsModel and AutoTokenizer. Files - model.safetensors - fine-tuned VITS model weights. - config.json, vocab.json, tokenizer files - model and tokenizer configuration. - examples/inference.py - minimal local inference script. - eval/benchmark/ - generated benchmark samples, review sheet, manifest, and timing summary. - training/ - training configuration and local wrapper used for this experiment. Raw training audio is not included in this release directory. Usage Or load the model directly: Evaluation The included benchmark generated 50 samples. See eval/benchmark/reviewsheet.csv for manual review fields and eval/benchmark/generated/ for generated WAV samples. Training Summary - Base model: facebook/mms-tts-khm - Epochs: 2 - Batch size: 2 - Sample rate: 16000 - Training seed: 987 Limitations This is an experimental single-speaker Khmer TTS model. Review pronunciation, naturalness, and text fidelity before production use. The benchmark samples are generated examples, not a full safety or quality evaluation. License This release uses cc-by-nc-4.0, matching the non-commercial license of the base MMS Khmer TTS model. Confirm that any downstream use complies with the base model license and the rights for the fine-tuning data. Citation If you use this model, cite the MMS work:

Using it via the API
Once AxForge deploys khmer-tts for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (khmer-tts below is illustrative; you get the exact model name on deployment.)
$ curl -sS https://api.axforge.ai/v1/audio/transcriptions \ -H "Authorization: Bearer $AXFORGE_API_KEY" \ -F model="khmer-tts" -F file=@audio.mp3

Licence
The weights are open but cc-by-nc-4.0 needs a commercial agreement for business use. AxForge can arrange that licence and host the model for you — you pay AxForge, we settle with the model’s maker. Ask us for a quote. Read the licence ↗
