The recording is your own Mandarin. Can you find out whether it is true or not?

Generally speaking, the authenticity of the recording cannot be determined, because the recording may be forged, tampered with or the original recording itself has problems. Legally, professional technical appraisal is needed to determine the authenticity of the recording, and the authenticity of the recording is evaluated through various factors such as sound characteristics, audio analysis and metadata.

If you need to identify the authenticity of the recording, you can seek the help of professional voice identification institutions or experts. They can judge the authenticity of the recording through audio analysis, sound feature extraction and other technical means. At the same time, it is necessary to combine other evidence, such as witness testimony and written materials, for comprehensive analysis and judgment.

It should be noted that even if the recording is proved to be true, its content is not necessarily legally valid evidence, which needs to be judged in combination with specific cases.
