# Zero-shot Voice Cloning on Seed-TTS-Eval Average Source: [Zero-shot Voice Cloning on Seed-TTS-Eval Average]() Collection index: [llms.txt]() Data updated: 2026-06-08T07:26:58.121Z Evaluation of Zero-shot Voice Cloning performance averaged across splits/languages on the Seed-TTS-Eval dataset, measured using Word Error Rate (WER) and Similarity (SIM). A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | Zero-shot Voice Cloning | | Dataset (including any stated split) | Seed-TTS-Eval Average | | Metric | WER (%) | | Unit | PERCENT | | Direction | Lower is better | | Results loaded | 12 of 12 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [WER (%)](): Lower is better; unit: PERCENT. - [Similarity Score](): Higher is better; unit: PERCENT. ## Recorded results | Method | WER (%) | Result date | Report paper | | --- | --- | --- | --- | | dots.tts (Pretrain) | 2.92 | Not recorded | 6a264c6390966ade919be869 | | dots.tts (MF, NFE=4) | 2.94 | Not recorded | 6a264c6390966ade919be869 | | dots.tts (SOAR) | 2.95 | Not recorded | 6a264c6390966ade919be869 | | CosyVoice 3 | 3.06 | Not recorded | 6a264c6390966ade919be869 | | Qwen3-TTS | 3.07 | Not recorded | 6a264c6390966ade919be869 | | dots.tts (MF, NFE=3) | 3.21 | Not recorded | 6a264c6390966ade919be869 | | dots.tts (MF, NFE=2) | 3.43 | Not recorded | 6a264c6390966ade919be869 | | IndexTTS 2 | 3.46 | Not recorded | 6a264c6390966ade919be869 | | Seed-TTS | 3.65 | Not recorded | 6a264c6390966ade919be869 | | VoxCPM 2 | 3.65 | Not recorded | 6a264c6390966ade919be869 | | FireRedTTS 2 | 4.02 | Not recorded | 6a264c6390966ade919be869 | | F5-TTS | 4.1 | Not recorded | 6a264c6390966ade919be869 | ### dots.tts (Pretrain) WER (%): 2.92.
