New inventive technology developed for people who cannot speak through the ‘LOQU’ device

There is a ray of hope for those who cannot speak, since researcher Dr. LN Sharma, Head, Department of Electronics and Electrical Engineering, Indian Institute of Engineering, Guwahati, has come up with an inventive technology to develop a device “LOQU” for the production of human speech using 3-dimensional acceleration signals due to fold vibrations without using an acoustic microphone. While talking to The Financial World, Dr. Sharma said that a MEMS sensor with non-invasive technology is placed on the laryngeal surface (voice box) to receive the three-dimensional source signals and generates human speech with a unique process, which has been patented . (Indian Patent No. 510923, grant date: 15/02/2024).

Dr. Sharma said that “LOQU” is derived from the Latin world “Speaking or talking – this technology consists of non-invasive procedures, using sensors placed over the throat, which runs on a rechargeable battery of 9 V volts and the total estimated cost of the model costs about Rs 2500. He said that in this invention due to the movement of various laryngeal muscles, cartilage and connective tissue during phonation, three-dimensional glottal vibration signals are captured, processed and a technology “LOQU” is created to understand human speech signals to create.
Dr. Sharma said that human speech production is a complex process involving breathing, sound formation and articulation. The very complex structures with larygeal functions make sound production possible. The larynx links phonation, articulation and resonance for speech production. The lungs initiate speech through the trachea with pulmonary egressive aggressive airflow, the glottis involving vocal folds in the larynx, the phonation and vocal tract along with the lips, teeth, buccal root, tongue, oral cavity and nasal cavity assist in articulation for speech production and during phonation moves the vocal folds towards each other and the voice is created.
