Definition
A laryngectomy is the surgical removal of the larynx (voice box), resulting in permanent loss of the natural voice. After the procedure, breathing occurs through a stoma in the neck, and sound can no longer be produced using the vocal cords.
Relevance for Vocal Heirloom
For people who undergo a laryngectomy, Vocal Heirloom can rebuild a version of their natural voice using recordings made before surgery.
This helps patients:
• communicate in a voice that sounds like their own
• avoid robotic-sounding text-to-speech systems
• preserve personal identity in everyday communication
Technical Background
• The vocal cords are removed, eliminating natural phonation.
• Common communication methods include electrolarynx devices, TE (tracheoesophageal) speech, and text-to-speech tools.
• AI models use pre-op recordings to reconstruct the individual’s original vocal characteristics.
• Even short or noisy recordings can provide usable vocal features.
Common Misunderstandings
• A laryngectomy does not remove the ability to speak in general — alternative speech methods exist.
• Pre-op recordings do not need to be studio quality.
• AI cannot recreate a voice if no audio of the patient exists.
• Post-op breathing sounds do not interfere with voice reconstruction.
Factors That Influence Reconstruction Quality
• Pre-op recordings with clear vowels and mid-range loudness.
• Less compression (e.g., original video files are better than old voicemail formats).
• Multiple short clips across different situations help capture a fuller vocal signature.
• Emotional consistency in the recordings improves stability.
Typical Useful Audio Sources
• Old smartphone videos
• Voicemails or carrier recordings
• WhatsApp or iMessage audio notes
• Social media clips with spoken segments
• Family recordings made casually at home
