Professional Cloning

Through professional voice cloning, you only need to provide one minute or longer (up to 60 minutes) voice samples, and our AI will deeply train and learn every detail of the tone, pronunciation, rhythm, prosody, etc. of the voice samples you provide within 3-60 minutes, achieving top-level cloning synthesis effects indistinguishable from the original voice, while retaining all cutting-edge features of the VOCU speech large model such as language understanding and emotional expressiveness.

Operation Process

Preparation

Before starting your professional cloning, you need to prepare one or more audio sample files for cloning.

Audio sample files need to meet the following requirements:

• The total duration of all audio sample files combined should be at least 1 minute and at most 60 minutes; within this range, the longer the total duration, the better the cloning effect.

• Each audio file needs to be in wav/mp3/mp4/flac/m4a/ogg format.

• Please ensure to provide high-quality audio whenever possible and ensure that the audio contains recognizable Chinese or English sentences. For more tips on ensuring cloning effects and quality, please refer to Important Notes

After the audio sample files are prepared, please pack them into an unencrypted Zip format compressed package, and the size of the compressed package must not exceed 256MB.

Start Cloning

After confirming that the above conditions are ready, please follow these steps:

1. Summon the character creation panel through the Add Character button on the Character Management page, or the "Quick Create New Character..." button in the bottom left corner of the Speech Generation page.

2. You need to specify a name for the character you create, and optionally specify a description and an avatar. Currently, names, descriptions and avatars are for display only and do not affect voice cloning behavior.

3. Click the Professional Cloning button to switch to the professional cloning tab; you will see a new "Professional Cloning Sample Package" section appear below the "Default Style Sample" column.

4. In the "Default Style Sample" column, please extract and select about 5-30 seconds of the most representative and high-quality audio from the series of audio samples you prepared for professional cloning, as the default style guide sample for this cloning; this default style sample will be used to define the character's default voice performance, including voice line, emotion, speed, tone, prosody, etc. (you can add more different style samples later in the character details page). You can also follow the same mode as instant cloning to select or record other audio not included in the compressed package as the default style sample; but to ensure the effect of professional cloning, we do not recommend you to perform such operations.

1. Finally, in the "Professional Cloning Sample Package" column, please select the Zip compressed package of audio sample files you prepared according to the previous requirements. After confirming that all content is correct, click the Add button in the bottom right corner to start uploading and submitting the professional cloning task.
