Aphonia

The investigators will conduct a pilot experiment for a novel and personalized method for voice restoration using machine learning applied to surface EMG (sEMG) signal from articulatory muscles of the face and the neck allowing recognition of silent speech. The investigators predict that the use novel personalized method for voice restoration will be feasible and successful for patients.

The goal of this clinical trial is to compare face-to-face group voice therapy to telepractice group voice therapy for muscle tension dysphonia (MTD). The main questions it aims to answer are: * The effectiveness of telepractice voice therapy for MTD using a randomized controlled trial study design. * The effectiveness of telepractice group voice therapy using a randomized controlled trial study design. Participants will receive telepractice group voice therapy or face-to-face group voice therapy. Researchers will compare telepractice group voice therapy to face-to-face group voice therapy for patients with MTD to see if it has the same effectiveness.
