1. Audio duration: 10–20 seconds, no more than 60 seconds. Please keep the reading continuous, with at least one segment of continuous speech longer than 5 seconds.

2. The choice of recording environment mainly considers reducing noise and reverberation. It is recommended to use a small room within 10 square meters for recording, especially rooms with sound-absorbing equipment.

3. Keep a distance of about 10 cm from the microphone during recording to avoid clipping or electrical noise.

4. Indoor noise mainly comes from air conditioners, fans (including computer fans), fluorescent ballast, human voices, etc. You can use your phone to record the 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. Keep the reading continuous and avoid unnecessary pauses (at least 5 seconds continuously), as this will severely affect the replication effect and may even cause it to fail.

6. It is recommended to familiarize yourself with the script before recording and determine the character and performance style. Read with emotion, avoiding mechanical “reading”, to avoid the replicated effect not matching your expectations.

7. There are no special restrictions on the content of the script, but please do not read scripts with sensitive words as this will cause the replication to fail.
