Abstract

Owing to recent progress in digital signal processors developments it has been possible to build a subminiature device combining speech and hearing aid. Furthermore, despite its small dimensions, the device can execute quite complex algorithms and can be easily reprogrammed. The paper puts an emphasis on issues related to the design and implementation of algorithms applicable to both speech and hearing aids. Frequency shifting or delaying the audio signal are often used for speech fluency improvement. The basic frequency altering algorithm (FAF) is similar to the sound compression algorithm used in some special hearing aid as above. Therefore, the experimental device presented in the paper provides a universal hearing & speech aid which may be used by hearing or by speech impaired persons or by persons suffering from both problems, simultaneously.
