A multilingual, multi-speaker text-to-speech model fine-tuned from unsloth/orpheus-3b-0.1-pretrained on the full Sunbird/tts corpus — 20 language configurations and every speaker present in the dataset. The model accepts arbitrary text and emits 24 kHz mono speech via the SNAC audio codec. Voice selection happens at the prompt level: prepend the chosen speakerid followed by ": " to your text, and the model produces audio in that speaker's voice. Speaker IDs encode both the source corpus (salt, waxal, slr32, slr129, bateesa) and the language. Languages marked with an em dash in the Speaker IDs column are present in the model's training mix but do not currently expose individual voice IDs in this checkpoint. Per-language quality scales with the amount of training data Sunbird collected for that language; some configs have many more speaker hours than others. Audition the test split for each language before relying on a particular speaker — see the…

Parameter count is not a RAM/VRAM requirement. Check precision, quantization, context length and runtime compatibility in the model card; no hardware or API-cost claim is inferred here.
Use and evaluate
Check license terms and access requirements first. Review the model card’s documented loading instructions, evaluations and safety limitations. Benchmark scores are not imported by this directory, and popularity is not an accuracy ranking.
No model weights are downloaded or executed by AltAPIs. Never enable remote model code without reviewing it.
