Zero-Shot Voice Cloning Across Reference Conditions

MOSS-TTS v1.5 is an open-source zero-shot cloning candidate for an authorized voice library. Its published 8B evidence includes English WER of 1.84%, Chinese CER of 1.37%, and English and Chinese speaker similarity scores of 70.86 and 76.98. Rankings depend on the chosen metric, language, and candidate set. 8B evaluation · OpenMOSS table

Compare reference conditions rather than highlight clips

Seed-TTS-eval uses speaker embeddings and cosine similarity to assess resemblance. It scores intelligibility separately. The v1.5 card also reports improved cloning consistency compared with v1.0. These are different questions: resemblance in one output and repeatability across generations. Evaluation implementation · v1.5 card

For a proposed voice-library evaluation, group consented reference clips by recording conditions such as close-miked studio speech and lightly reverberant speech. Keep the approved target scripts fixed across groups. Run multiple generations per condition, retain all outputs, and use blinded listeners alongside the automated scores.

A deployment report should describe the test conditions before claiming leadership. The model report supplies architecture and benchmark context. Report any new result with its actual sample count and checkpoint. Technical report
