IIT Guwahati Develops Cutting-Edge Speech Reconstruction Tech; Check Details Here

IIT Guwahati has developed and patented "LOQU", an innovative technique for producing human speech signals directly from vocal cord vibration signals. Know details here 

Researchers at the Indian Institute of Technology Guwahati have made a major advancement in speech technology by developing and patenting "LOQU," a new method that generates human speech signals directly from vocal cord vibrations. This innovative approach allows for the reconstruction of speech signals from vocal cord vibrations, offering promising applications for speech-impaired individuals and medical settings.

Under the guidance of Prof. Samarendra Dandapat, Department of Electronics and Electrical Engineering, and led by Dr. L.N. Sharma of IIT Guwahati, the team, including Pharvesh Salman Choudhary, Sibasis Sahu, Debasis Jyotishi, Moirangthem James Singh, Samarjeet Das, and Yengkhom Omesh Singh, has created "LOQU." Derived from the Latin word for "To speak or talk," this technology captures vocal fold movement without invasive procedures, utilizing sensors placed over the throat. 

Speaking about the developed device, Prof. Samarendra Dandapat, Department of Electronics and Electrical Engineering, and lead of the Electro Medical and Speech Technology Group, IIT Guwahati, said, “This breakthrough holds immense promise for individuals facing speech impairments, offering a viable solution with clear and comparable speech signals, as demonstrated in comparison tests. With 'LOQU,' we aim to empower those in need and drive impactful innovations in the medical and communication domains.”

The reconstructed speech signals are clear and comparable to traditional speech in extensive comparison tests. These results hold significant potential for individuals struggling with speech impairments, offering a viable alternative to traditional microphones, and enhancing speech clarity.

Prototype of LOQU

The prototype of LOQU has been developed on a laboratory scale at a cost of under INR 2000. The patented technology (Indian Patent No.: 510923, Grant Date: 15/02/2024, App No. 201831006870) represents a significant milestone in speech research and innovation, with ongoing clinical testing aimed at further validating its effectiveness and exploring diverse applications in medical and communication fields.
