1. Audio duration: 10-20 seconds, preferably not exceeding 60 seconds. Please maintain continuity while reading, with at least one segment of continuous speech over 5 seconds.

2. When selecting the recording environment, focus on reducing noise and echo. It is recommended to use a small room of 10 square meters or less, preferably with soundproofing devices for better recording quality.

3. Maintain a distance of approximately 10 cm from the microphone during recording to avoid popping sounds or electrical noise.

4. Indoor noise mainly comes from air conditioners, fans (including computer fans), fluorescent light ballasts, and human voices. You can use your phone to record environmental sounds, amplify the volume, and listen to the recording to identify and turn off noise sources.

5. Avoid using short sentences with only a few words in the script. Maintain continuity while reading, avoiding frequent unnecessary pauses (at least 5 seconds). This will severely impact the cloning effect and may lead to failure.

6. It is recommended to familiarize yourself with the script before recording and determine the character and style of delivery. Use expressive reading rather than mechanical reading to ensure the cloning effect aligns with your expectations.

7. There are no special restrictions on the script content, but please avoid reading scripts with sensitive words as this may cause the cloning to fail.
