  • Anouncement for reed type artificial larynx MOKSORI at 14th Conference for voice and science-1st workshop for voice and language. Hanju Kim(represent of Moksori), Syunghee Choi(Prof), Sungun Im(Phd), Sungun Lee(PhD), Hongsik Choi(PhD) in Gangnam Severance Hospital, Seoul, South Korea.
  • Research condition

    For the development of artificial larynx, the acoustic characteristics of the four groups were analyzed, and the 3 spoken lagnuage Therapists listened and evaluated their speech. Gruop 1, normal adult voice speech Gruop 2, esophageal speech Gruop 3, electronic artificial larynx speech Gruop 4, Moksori speech Mesure and scored by Lx Speed Studio and Dr. speech Science. Ona 7 point scale.
