Abstract

A digital device to make speech in a helium atmosphere more intelligible includes a recirculating storage and an analog to digital converter which periodically samples the speech and the digital samples are loaded into the storage at a rate determined by a load counter. An unload counter continuously operating at a predetermined slower rate than the load counter unloads the stored digital representations of the speech and a digital to analog converter converts it back to an analog signal. The analog signal is utilized by an output means such as a loudspeaker and is an intelligible translation of the input speech. Since the storage is loaded at a faster rate than it is unloaded, it will periodically fill up, and no more digital samples are loaded, until such time as the storage is again emptied.
