Abstract
Abstract A method and system for translating or processing recorded speech to a slower rate of speech while retaining its original frequency values, with interposition of compensations which include intensification of ''''plosive'''' and other sounds which follow silences or breaks in the stream of speech.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
137 words
A data processing method for converting voice signals to speed-retarded voice signals for alpha-numeric print-out and for other means, comprising the steps of: 1. sensing a voice signal, 2. cycling the signal in essentially 0.05 second segments for two sets of recorder heads in 0.05 second displacement along a recording tape, 3. detecting a null input in essentially 0.05 second advance of the null reaching the sensing step and producing a gate output when no signal is detected, 4. sensing a rate of change in detecting a null input to activate a brake to stop drive means for said recording tape until change of the non-input condition, 5. driving gang switch means upon change of the non-input condition to provide simultaneously dual recording for a period of the first sounds that transpire following a period of silence.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
22 words
cycling the signal in essentially 0.05 second segments for two sets of recorder heads in 0.05 second displacement along a recording tape,
Claim 4
Dependent Claim
22 words
cycling the signal in essentially 0.05 second segments for two sets of recorder heads in 0.05 second displacement along a recording tape,
Claim 5
Dependent Claim
193 words
Data processing means for converting voice signals to speed-retarded voice signals for alpha-numeric print-out and for other means comprising: voice signal sensing means: a signal cycling means for receiving the output of the voice signal sensing means and dividing the voice signal into time divided components of essentially equal duration, recording means to store the divided components on tracks for each series of the divided components in time-sequential segments of storage means; a simultaneous sound pick-off means for taking each divided component from the storage means for synthesizing into a speech-retarded voice signal; a rate of change in voice to null input means sensing in a time interval in advance of said voice signal sensing means that a null input is approaching the voice signal sensing means; and a driving gang switch means responsive to a non-input condition providing simultaneously dual recording in the storage means for a period of the first sounds that transpire following a period of silence and inactivate the time-sequential recording function of the recording means, so that the simultaneous sound pick-off means takes each divided component from the storage means for synthesizing into an emphasized phoneme voice signal.
