Glossary

This glossary explains the essential terms behind voice reconstruction, audio quality and voice loss.
It helps patients, families and professionals understand how Vocal Heirloom restores natural-sounding voices using real recordings.

Voice AI & Restoration Terms

  • Voice Cloning – Rebuilding a natural voice from old recordings.
  • Voice Restoration – Creating a stable, unified voice from fragmented audio.
  • Voice Reconstruction – Creating a unified, stable voice model from fragmented, low-quality, or inconsistent recordings.
  • Audio Enhancement – Improving old or noisy recordings by removing distortion and restoring clarity for better voice analysis.
  • Voiceprint – A person’s unique acoustic signature made of pitch, resonance, and speech patterns.

Medical & Voice Loss Terms

  • Laryngectomy – A surgical removal of the voice box that results in permanent loss of natural vocal-cord speech.
  • ALS Voice Loss – The gradual loss of speech caused by ALS as motor neurons weaken and vocal control declines.
  • Tracheoesophageal Speech (TE Voice) – A post-laryngectomy speech method that uses esophageal vibrations instead of vocal-cord sound.
  • Electrolarynx – A handheld device that produces mechanical vibrations to enable speech after vocal-cord removal.
  • Whispered Speech – Speech produced without vocal-cord vibration, lacking pitch and full vocal identity.
  • Head and Neck Cancer – A group of cancers that often affect speech and can lead to partial or total loss of the natural voice.

Audio Quality & Technical Terms

  • Signal-to-Noise Ratio (SNR) – The balance between clear speech and background noise that determines how usable a recording is.
  • Clipping – Audio distortion caused when sounds are recorded too loudly, cutting off vocal detail.
  • Bitrate – The amount of audio data stored per second, affecting how much vocal detail is preserved.
