Upload a 3-10 second clear audio clip. The audio should only contain the target speaker's voice, avoiding background noise. Supports common formats like WAV, MP3.

Step 2: Select Emotion Tag (Optional)

Choose an emotion type based on your needs, such as "Happy", "Sad", "Angry", etc. You can also adjust the emotion intensity (0-2), with higher values indicating stronger emotion. Not selecting an emotion tag will maintain the original voice.

Step 3: Enter Text to Synthesize

Enter the text you want to synthesize in the text box. It's recommended to use standard punctuation for more natural results.

Step 4: Click Generate

Click the "Generate Voice" button. The system will automatically queue, load the model, upload audio, and synthesize speech. Once complete, you can play and download online.

Tips:

• The clearer the reference audio, the better the cloning effect

• Avoid uploading audio with background music or noise

• Punctuation in the text will affect the pauses and intonation of the speech

• Setting emotion intensity to 1.0 usually gives the best results
