ghana-vc-Nkonya_nko
Voice conversion for Nkonya (nko). An audio-to-audio model that converts speech into the Zephyr voice while preserving the language.
This checkpoint is dedicated to Nkonya: it was fine-tuned only on Nkonya (nko) clips from ghanaopenai/ghana-synthetic-speech, starting from the zero-shot seed-uvit-whisper-small-wavenet base. Use it to convert audio in Nkonya. For other languages — or as a cross-lingual fallback — use ghanaopenai/ghana-vc.
Use with ghana-vc
pip install git+https://github.com/GhanaNLP/ghana-vc
export HF_TOKEN=hf_...
ghana-vc convert \
--dataset <org>/<audio-dataset> \
--output <org>/<result> \
--config-name Nkonya_nko \
--num-samples 100
The library auto-selects this model when the dataset/config name matches.

Training
- Dataset:
ghanaopenai/ghana-synthetic-speechconfigNkonya_nko(Nkonya) - Base:
seed-uvit-whisper-small-wavenet(zero-shot) - Weights: the step-1,000 checkpoint. Comparing checkpoints from 500 to 3,500 steps on Asante Twi, step 1,000 kept pronunciation clearest (lowest character error rate with Omnilingual ASR CTC-300M), so it is the one published.
