Abstract

The invention includes a handheld device for receiving audio input in the form of speech. The handheld device is specifically optimized for digitally recording speech input for the purpose of speech recognition. The handheld device includes an ergonomically positioned pointing device to enable dictation and navigation through a document using only one hand. The handheld device may optionally include a memory device, a fingerprint security device, and a barcode scanner.

Claims

1. A handheld device for receiving speech as audio input, converting speech to text and for entering the text into a computer operatively connected to a database for storing at least one electronic form having a plurality of sections, the handheld device comprising:

a microphone operatively connected to the handheld device,

a wind screen affixed to the microphone, the wind screen selected according to a predetermined wind noise sensitivity,

an analog-to-digital converter, said analog-to-digital converter transforming analog signals from the microphone into digital signals received by the computer and recognized as text,

a gain control element electrically connected between the microphone and the analog-to-digital converter, the gain control element operatively maintaining the analog signals at a level suitable for speech recognition, and

a plurality of input buttons on the handheld device, where at least one of the plurality of input buttons is programmed to direct text insertion to a section of the form preassigned to said at least one input button when said at least one input button is activated,

an activator button for initiating receiving of the audio input text into the section of the form selected by the user by activating said at least one programmable button,

a bar code scanner, and

a controller, said controller sending a signal to mute a speaker upon the activation of an element with excessive current requirements.

2. The handheld device of claim 1, wherein the plurality of input buttons includes a button for advancing to a next predetermined section of the form and a button for going back to the previous predetermined section of the form.

3. The handheld device of claim 1, wherein the plurality of input buttons includes a button for selecting a portion of text.

4. The handheld device of claim 1, wherein the plurality of input buttons includes a button for reviewing back through an audio file to a previously recorded portion of the file, a button for advancing through an audio file to a previously recorded portion of the file, and a button for playing a portion of an audio file through an integrated speaker on the handheld device.

5. The handheld device of claim 4, wherein the button for playing a portion of an audio file is also a stop button, wherein when any function of the handheld device is active, pressing the stop button deactivates the handheld device.

6. The handheld device of claim 1, wherein the plurality of input buttons includes a button for dictation, wherein when the button for dictation is pressed, the microphone is activated to receive speech as audio input, the audio input is digitized and transmitted to a speech recognition engine, and the speech recognition engine translates the speech into text.

7. The handheld device of claim 1, further comprising a pointing device on the top surface of the handheld device and at least one button associated with the pointing device.

8. The handheld device of claim 7, wherein the pointing device is a microjoystick.

9. The handheld device of claim 7, wherein the at least one button associated with the pointing device is on the bottom surface of the handheld device.

10. The handheld device of claim 1, wherein the plurality of input buttons includes a button for signing a form, wherein when the button for signing a form is pressed, the form is modified to include an indicator that the form has been signed.

11. The handheld device of claim 1, wherein the plurality of input buttons includes a button for coding.

12. The handheld device of claim 1, wherein the input buttons are programmed by the user.

13. The handheld device of claim 1, wherein the electronic form is displayed on a computer monitor operatively connected to the computer.

14. The handheld device of claim 1, wherein the plurality of input buttons are ergonomically positioned.

15. The handheld device of claim 1, wherein the plurality of buttons is positioned on the handheld device to allow one-handed navigation through the form.

16. The handheld device of claim 1, wherein the handheld device is operatively connected to the computer by a universal serial bus (USB) connection.

17. The handheld device of claim 1, wherein the bar code scanner recognizes said at least one electronic form and the plurality of sections corresponding to said at least one form.
