AI-Based Speech Restoration App: How It Works and Benefits

Context

Researchers at the International Institute of Information Technology Hyderabad developed an AI-based app that converts impaired speech into clear speech in near real-time.

About the Technology

• Speech Restoration System: The app converts distorted or slurred speech into intelligible speech using Artificial Intelligence and Machine Learning models.
• Near Real-Time Processing: The system works with a delay of only a few hundred milliseconds, enabling natural conversation flow.
• Multimodal Input Approach: It uses both audio signals and visual inputs (lip movements, throat vibrations) to generate clear speech.

Key Technologies Involved

• Artificial Intelligence (AI): Uses deep learning models to process and reconstruct speech signals.
• Computer Vision: Analyses lip movements and facial cues to generate speech when audio is unclear or absent.
• Speech Processing Models: Converts noisy or impaired speech into structured, intelligible output.
• Voice Synthesis (Text-to-Speech): Generates clear and natural-sounding speech output

Target Condition: Dysarthria

• Motor Speech Disorder: Dysarthria is a condition where muscle weakness affects speech clarity, leading to slurred or slow speech.
• Impact on Life: It affects communication, independence, and social interaction, making assistive technology crucial.
