Researchers at IIT Guwahati developed the "LOQU", a novel method to generate human speech signals directly from vocal cord vibration signals.

❖ It can capture vocal fold movement without invasive procedures, utilizing sensors placed over the throat.

❖ During speech, vocal folds vibrate due to intrinsic laryngeal muscle movement.

❖ In some cases, like mutism from apraxia, individuals may have normal vocal fold vibration without sound production

❖ For the above issue, LOQU can be used for the reconstruction of speech signals from vocal cord vibrations.
