Abstract
Abstract A learning aid is provided which allows the user to selectively mute one part of a prerecorded multipart drama and substitute his or her voice for that muted part. A recorded copy of a composite of the unmuted prerecorded portions of the drama, the user's voice, and additional sound effects may thus be created. A voice sensitive microphone allows the period of time for the user's part to be flexibly varied and prerecorded control signals provide visible cues to the user that the part selected is imminent.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
209 words
An electronic learning aid for readers using an audio prerecorded multipart drama medium, the multipart drama having multiple spoken parts, the learning aid comprising: a script providing a transcription of spoken parts of the multipart drama; a playback means receiving the prerecorded multipart drama medium for playing of the multipart drama; a part selector switch identifying a selected one part of the multipart drama; a part selector communicating with the playback means and the part selector switch to play back parts of the multipart drama other than the selected one part of the multipart drama selected by the switch; a microphone providing a vocal input signal; and a recording means communicating with the playback means and the microphone to record the parts of the multipart drama other than the selected one part of the multipart drama and the vocal input signal from the microphone; whereby a reader may read a part of the multipart drama and produce a complete recording of the drama; and further including a threshold detector circuit communicating with the microphone and the playback means, the threshold detector circuit providing an electrical signal stopping the playing of the multipart drama for a period of time while the vocal input signal is being received from the microphone.

An electronic learning aid for readers using an audio prerecorded multipart drama medium, the multipart drama having multiple spoken parts, the learning aid comprising: a script providing a transcription of spoken parts of the multipart drama; a playback means receiving the prerecorded multipart drama medium for playing of the multipart drama; a part selector switch identifying a selected one part of the multipart drama; a part selector communicating with the playback means and the part selector switch to play back parts of the multipart drama other than the selected one part of the multipart drama selected by the switch; a microphone providing a vocal input signal; and a recording means communicating with the playback means and the microphone to record the parts of the multipart drama other than the selected one part of the multipart drama and the vocal input signal from the microphone; whereby a reader may read a part of the multipart drama and produce a complete recording of the drama; and further including a threshold detector circuit communicating with the microphone and the playback means, the threshold detector circuit providing an electrical signal stopping the playing of the multipart drama for a period of time while the vocal input signal is being received from the microphone.
Claim 3
Dependent Claim
83 words
The electronic learning aid of claim 1 wherein the prerecorded multipart drama includes embedded cue signals and wherein the learning aid further includes a decoder communicating with the playback means to detect the cue signals and to provide a visual indication of an impending start of the selected one part of the multipart drama, and wherein the threshold detector circuit stops the playback of the multipart drama for a period of time while the vocal input signal is being received from the microphone.
Claim 4
Dependent Claim
246 words
An electronic learning aid for readers using a prerecorded multipart drama medium divided into at least three tracks, a first and second track containing different spoken parts of the multipart drama and a third track containing non-spoken background sound effects, the learning aid comprising: a script providing a transcription of spoken parts of the multipart drama; a playback means receiving the prerecorded multipart drama medium for playing the three tracks of the multipart drama; a part selector switch identifying one part of the multipart drama; a part selector communicating with the playback means and the part selector switch to select one of the first and second tracks of the multipart drama containing other than the one part identified; a microphone providing a vocal input signal; a speaker communicating with the playback means to broadcast the selected track and the third track; a recording means communicating with the playback means and the microphone to record the selected track and the third track and the vocal input signal from the microphone; and whereby a reader may read a part of the multipart drama and produce a complete recording of the drama; and further including a threshold detecting circuit communicating with the microphone and the playback means, the threshold detecting circuit stopping the playing of the selected track of the multipart drama for a period of time while the vocal input signal is being received from the microphone, but continuing a playing of the third track of background sounds.
Claim 5
Dependent Claim
