A multilingual speech-model adapter for Yoruba, Hausa, Igbo and Nigerian Pidgin.
Published model
Concept diagram. Text → Orpheus-3B with LoRA → Speech in four languages.
SoroTTS adapts a 3B speech model for four Nigerian languages. It supports natural-language audio output and powers the voice layer of Naija Solar.
The problem
Speech interfaces need better support for African languages and accents if they are to be useful outside English-first workflows.
The approach
Fine-tune an Orpheus-3B speech backbone with a LoRA adapter across multilingual speech clips; publish weights, examples, model card and limitations.
Scope and limits
Published under a CC BY-NC-SA 4.0 noncommercial licence because some training data is noncommercial. Commercial use requires a separately compliant model.
