Embodiment Construction
[0029]FIG. 1 depicts some of the major components of the current invention, including an excitation device 2 on the neck together with a contact microphone 4. Generally for devices mounted inside the mouth, a radio frequency signal carries the information about the glottal pulse. For neck mounted vibrators, wires would generally be used to carry the signal. However, a self contained neck vibrator 6 using an rf signal and its own batteries for power could be used. For the case of some tracheo-esophageal puncture speakers, their own voice sound may be used as the primary excitation.
[0030] A microphone is worn in front of the mouth, in the mouth, or coupled through tissue or bone to the vocal tract. The neck mounted device and the microphone are connected to a control circuit directly by wires, or through electromagnetic field transmission such as a radio frequency transmission or infrared light coupling system. The unit may also be adapted to directly connect to a telecommunication d...
