Abstract

The invention relates to a portable voice recording device. The device includes a microphone for generating an electrical signal representative of an acoustic speech signal. An analog to digital converter receives the electric signal from the microphone and generates a digital memory signal representative of the electric signal. A memory device stores the digital memory signal. In response to a user'"'"'s request, a digital to analog converter converts the memory signal to an analog electrical signal which drives a loudspeaker to generate an acoustic reproduction of the original speech signal. Also, in response to a user'"'"'s request, the device transmits the memory signal to an output terminal for transmission to a processing device.

Claims

1. A portable voice recording device comprising:

a microphone for generating an electrical signal representative of an acoustic speech signal,

a digital to analog converter for receiving said electrical signal from said microphone and generating in response thereto a digital memory signal representative of said electric signal,

memory device for storing said memory signal, and

an output port controller for transmitting said memory signal to a remote device.

2. The portable voice recording device of claim 1 further comprising:

a digital to analog converter for converting said memory signal to an analog electrical signal, and

a loudspeaker for generating an acoustic signal corresponding to said analog signal.

3. The portable voice recording device of claim 1 further comprising:

an output port, connected to said output port controller, for allowing said user to connect said portable voice recording device to a remote device.

4. The portable voice recording device of claim 1 further comprising a download selection mechanism for allowing a user to instruct the voice recording device to transmit said memory signal to said remote device.

5. The portable voice recording device of claim 1 further comprising a chassis having a size and shape which allows said chassis to fit in a user'"'"'s hand, wherein said microphone, said digital to analog converter, said memory device and said output port controller are all housed within said chassis.

6. A portable voice recording device comprising:

a microphone for generating an electrical signal representative of an acoustic speech signal,

an analog to digital converter for receiving said electric signal from said microphone and generating a digital memory signal representative of said electric signal,

memory device for storing said digital memory signal,

a digital to analog converter for converting said memory signal to an analog electrical signal,

a loudspeaker for generating an acoustic signal corresponding to said analog signal,

an output terminal,

an output port controller for transmitting said memory signal to said output terminal, and

a download selection mechanism for allowing a user to instruct the output port controller to transmit said memory signal to said output terminal.

7. A portable voice recording device comprising:

a microphone for generating an electrical signal representative of an acoustic speech signal,

memory device for storing a memory signal representative of said electrical signal,

an output port controller for transmitting said memory signal to a remote device,

download selection mechanism for allowing a user to instruct the voice recording device to transmit said memory signal to said remote device, wherein said download selection mechanism comprises a switch having a plurality of settings, at least one of said settings instructing said voice recording device to transmit said memory signal to said remote device.

8. The portable voice recording device of claim 7 further comprising a chassis having a size and shape which allows said chassis to fit in a user'"'"'s hand, wherein said microphone, said memory device, and said output port controller are all housed within said chassis.

9. A portable voice recording device comprising:

a microphone for generating an electrical signal representative of an acoustic speech signal,

memory device for storing a memory signal representative of said electric signal,

an output port controller for transmitting said memory signal to a remote device,

a loudspeaker for generating an acoustic signal corresponding to said memory signal, and

a download controller for disabling said loudspeaker from generating said acoustic signal while said output port controller transmits said memory signal to said remote device.

10. The portable voice recording device of claim 9 further comprising a chassis having a size and shape which allows said chassis to fit in a user'"'"'s hand, wherein said microphone, said memory device, said output port controller, said download controller are all housed within said chassis.

11. A portable voice recording device comprising:

a microphone for generating an electrical signal representative of an acoustic speech signal,

memory device for storing a memory signal representative of said electric signal,

an output port controller for transmitting said memory signal to a remote device, and

a download controller for automatically terminating said output controller from transmitting said memory signal when said entire memory signal has been transmitted.

12. The portable voice recording device of claim 11 comprising a dictation detection mechanism for monitoring said memory signal to determine whether said memory contains additional dictation.

13. The portable voice recording device of claim 12 wherein said dictation detection mechanism includes an energy detection mechanism for determining the average energy of said memory signal.
