A novel optical fiber microphone system for recognizing devoiced vowels has been studied. This system consists of the optical detection of moisture pattern formed by devoiced breath and its recognization process using a modified DP-matching. To detect moisture pattern of devoiced vowels, five plastic optical fiber moisture sensors with fast response were developed and used. Using this system, high discernment rate over 93% was obtained for the devoiced vowels. This system will be used for verbally handicapped people to create sounds with a small effort in the near future.
