Abstract

A voice transcription system employing a speech engine to transcribe spoken words, detects the spelled entry of words via keyboard or voice to invoke a database of common words attempting to complete the word before all the letters have been input. This database is separate from the database of words used by the speech engine. A voice level indicator is presented to the operator to help the operator keep his or her voice in the ideal range of the speech engine.

Claims

1. A voice transcription system comprising:

an input circuit receiving a voice signal of spoken words from a remote source;

a speech engine generating input text including first text words corresponding to the spoken words;

a call assistant input circuit receiving at least one letter input for second text words from a call assistant monitoring at least one of the voice signal and the input text, the call assistant input circuit including multiple sets of second text words to select an anticipated second text word from the letter input prior to indication by the call assistant of completion of the second text word;

a display device to display the anticipated second text word to the call assistant; and

an output circuit transmitting at least one of the first text words and the second text word to a remote user.

2. The voice transcription system of claim 1 wherein the display device is further configured to display the input text as printed text;

and

wherein the call assistant input circuit includes a means for the call assistant to accept or reject the displayed second text word.

3. The voice transcription system of claim 2 wherein the displayed second word is rejected upon receipt by the call assistant input circuit receiving an additional letter input not conforming to the displayed second text word.

4. The voice transcription system of claim 3 wherein upon a rejection of the displayed second word by receipt of an additional letter input not conforming to the displayed second text word, the call assistant input circuit selects a new second text word from the multiple sets of second words.

5. The voice transcription system of claim 2 wherein the display device provides a touch screen identifying a point of touch on the screen and wherein the displayed second word is accepted by a touch of the screen at a location of the displayed second word.

6. The voice transcription system of claim 2 wherein the displayed second word is accepted by entry of a designated entry character.

7. The voice transcription system of claim 6 wherein the designated entry character is an enter key on a keyboard.

8. The voice transcription system of claim 1 wherein the call assistant input circuit accepts typed letter input from the call assistant via a keyboard.

9. The voice transcription system of claim 1 wherein the call assistant input circuit accepts spoken letter input from the call assistant via the speech engine.

10. The voice transcription system of claim 1 wherein the memory includes multiple sets of second words and wherein the input circuit further receives a remote source identifier to select from among the sets of second words for selecting a second word.

11. The voice transcription system of claim 1 wherein the remote identifier is a caller identification number.

12. The voice transcription system of claim 1 wherein the remote identifier is an electronically readable serial number of a telephone device.
