# Voice Cloning on CV3-Eval multilingual voice cloning (test) Source: [Voice Cloning on CV3-Eval multilingual voice cloning (test)]() Collection index: [llms.txt]() Data updated: 2026-03-20T08:19:23.059Z Evaluation of Voice Cloning performance on the test split of the CV3-Eval multilingual dataset, measured using Word Error Rate (WER) across multiple languages (English, Chinese, Japanese, Korean, German, Spanish, French, Italian, Russian) and hard subsets. 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 | Voice Cloning | | Dataset (including any stated split) | CV3-Eval multilingual voice cloning (test) | | Metric | WER (zh) | | Unit | SCALAR | | Direction | Lower is better | | Results loaded | 18 of 18 | | 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 (zh)](): Lower is better; unit: SCALAR. - [WER (en)](): Lower is better; unit: SCALAR. - [WER (ja)](): Lower is better; unit: SCALAR. - [WER (ko)](): Lower is better; unit: SCALAR. - [WER (de)](): Lower is better; unit: SCALAR. - [WER (es)](): Lower is better; unit: SCALAR. - [WER (fr)](): Lower is better; unit: SCALAR. - [WER (it)](): Lower is better; unit: SCALAR. - [WER (ru)](): Lower is better; unit: SCALAR. - [WER (hard subset, zh)](): Lower is better; unit: SCALAR. - [WER (hard subset, en)](): Lower is better; unit: SCALAR. ## Recorded results | Method | WER (zh) | Result date | Report paper | | --- | --- | --- | --- | | Fish Audio S2 | 2.65 | Not recorded | 69b0f6e92d603e6de3e45b93 | | CosyVoice3 | 2.89 | Not recorded | 69b0f6e92d603e6de3e45b93 | | CosyVoice3-0.5B+DiffRO | 2.89 | Not recorded | 69bcd48b0636e5bf4afc29f4 | | Fish Audio S1 | 2.98 | Not recorded | 69b0f6e92d603e6de3e45b93 | | CosyVoice2 | 3 | Not recorded | 69b0f6e92d603e6de3e45b93 | | CosyVoice2+DiffRO | 3 | Not recorded | 69bcd48b0636e5bf4afc29f4 | | CosyVoice3 | 3.01 | Not recorded | 69b0f6e92d603e6de3e45b93 | | CosyVoice3-1.5B+DiffRO | 3.01 | Not recorded | 69bcd48b0636e5bf4afc29f4 | | MOSS-TTS-Local-Transformer | 3.68 | Not recorded | 69bcd48b0636e5bf4afc29f4 | | CosyVoice3-0.5B | 3.89 | Not recorded | 69bcd48b0636e5bf4afc29f4 | | CosyVoice3-1.5B | 3.91 | Not recorded | 69bcd48b0636e5bf4afc29f4 | | MOSS-TTS-Local-Transformer | 3.95 | Not recorded | 69bcd48b0636e5bf4afc29f4 | | CosyVoice2 | 4.08 | Not recorded | 69bcd48b0636e5bf4afc29f4 | | MOSS-TTS | 4.26 | Not recorded | 69bcd48b0636e5bf4afc29f4 | | MOSS-TTS | 4.42 | Not recorded | 69bcd48b0636e5bf4afc29f4 | | Spark-TTS | 5.15 | Not recorded | 69bcd48b0636e5bf4afc29f4 | | F5-TTS | 5.47 | Not recorded | 69bcd48b0636e5bf4afc29f4 | | GPT-SoVits | 7.34 | Not recorded | 69bcd48b0636e5bf4afc29f4 | ### Fish Audio S2 WER (zh): 2.65.
