On the restoration of Shackleton's voice

Abstract

Shackleton's voice, which attempted to explore Antarctica 100 years ago, was vividly restored with voice-processing technology. The restored voice was used as a restoration criterion after restoring the sound quality to a sound quality by applying noise processing technology to the voice of Shackleton who finished the exploration and gave a speech at a university. The basic voices of the voices are similar to those of family members and relatives because of the similarity of the gene structure and the body structure. Using Shackleton's great-grandson voices, he restored Shackleton's voice by adjusting the rate of speech, intensity, intonation, duration, tone changes, and tone averages as analyzed in Shackleton's voice. The subjective evaluation of the restored voice showed a similarity of more than 90% in the spectral SNR compared to the original voice, and when MOS evaluation was performed by the linguistic expert, 4.5 / 5 was obtained and the restoration of the voice of Shackleton was successful respectively. It is expected that the restoration technology of the deceased using the relative of relatives can restore the message of love and encouragement to the family in their future voice to the descendants.
