| Summary: | Phonation duration is an important diagnostic tooi for patiënt having stuttering and voice disorders. Blinds are unable to read the display of a phonation duration meter commonly used by sighted people. The device suggested in this paper would provide tactile indicators (vibrating type) of phonation time in Braille, using six dots. In a similar way six vibrating tactile indicators have been used to inform the user about the loudness level of the sound produced by him during the process of measurement. Four different loudness levels (viz. Extra high, high, medium and low) have been incorporated. The device will automatically stop counting the phonation time if the loudness of the voice falls below the level set by the user at any instant during the measurement period and finally will store the measured values. This device is a low cost, portable and can also be used for the purpose of speech therapy |
