Soprano 1.1 Released: Significant Improvements in Audio Quality and Stability for Local TTS Model

This announcement highlights iterative improvements in a local TTS model, addressing key issues like audio artifacts and hallucinations. The reported preference by the developer's family, while informal, suggests a tangible improvement in user experience. However, the limited scope and the informal nature of the evaluation raise questions about generalizability and scalability of the findings.

• •Soprano 1.1-80M demonstrates a 95% reduction in hallucinations compared to the original model.
• •The updated model exhibits a 50% lower WER and supports up to 30-second sentences.
• •The developer reports a 63% preference rate for Soprano 1.1's output in a family-based study.
