Abstract

Embodiments include a system, method, and apparatus for creating a trusted speech transcription. Transcription logic can receive a signal of audible speech from an audio source and convert the audible speech signal into text. Sampling logic can receive the signal of the audible speech and record a portion of the of the audible speech as a digital audio recording of the audible speech. Packaging logic can create a trusted speech transcription data record that includes the text and the digital audio recording and to digitally sign the transcription file to securely associate the text with the digital audio recording.

Claims

1. An trusted speech transcription apparatus for creating a trusted speech transcription data record, the apparatus comprising:

transcription logic implemented at least partially in hardware to receive a signal of audible speech from an audio source and to convert the signal into text;

sampling logic implemented at least partially in hardware to receive the signal of the audible speech and to record signal of audible speech as a digital audio recording of the audible speech; and

packaging logic implemented at least partially in hardware to create the trusted speech transcription data record that includes the text and the digital audio recording and to digitally sign the trusted speech transcription data record to securely associate the text with the digital audio recording.

2. The apparatus of claim 1, wherein the packaging logic tags the transcription file with metadata associated with the audible speech.

3. The apparatus of claim 2, wherein the metadata comprises one or more of a time stamp, an internet protocol (IP) address of the audio source, an identification of a speaker of the audible speech, or an identifier of the source of the audible speech.

4. The apparatus of claim 1, further comprising activation logic to activate the transcription logic and the sampling logic upon detecting a triggering event.

5. The apparatus of claim 4, wherein the triggering event is the reception by the activation logic of one or more of a predetermined word or phrase, a signal quality, an identification of the speaker, or duration of the audible speech.

6. The apparatus of claim 1, wherein the transcription logic converts the signal of the audible speech and the sampling logic records the signal representing audible speech substantially in parallel.

7. The apparatus of claim 1, wherein the sampling logic records a fragment of the signal representing audible speech and the digital audio recording is a recording of the fragment of the audible speech, the fragment of the audible speech representative of a source of the audible speech.

8. The apparatus of claim 7, wherein the fragment of the audible speech comprises quality characteristics to identify a speaker of the audible speech.

9. The apparatus of claim 7, wherein the fragment of the audible speech is stored with a corresponding transcription of the audible speech.

10. A record processing apparatus for processing information in a trusted speech transcription session wrapper, the record processing apparatus comprising:

a content processor implemented at least partially in hardware to process text representing a transcribed audio signal;

a package validator implemented at least partially in hardware to authenticate the trusted speech transcription data record; and

an identity proof engine implemented at least partially in hardware to compare text with a corresponding voice record fragment, both of which are contained in the trusted speech transcription data record, and to identify a speaker of the voice record fragment.

11. The record processing apparatus of claim 10, wherein the package validator authenticates the trusted speech transcription data record with a digital signature.

12. The record processing apparatus of claim 10, wherein identity proof engine identifies the speaker of the voice record fragment by comparing the voice record fragment with recorded speech by speaker.

13. The record processing apparatus of claim 10, wherein the content processor is configured to receive a search request for a word of a phrase and to execute a text search of the word or phrase.

14. A computer program product tangibly embodied on a non-transitory computer readable medium, the computer program product including instructions that are operable when executed to:

receive a signal of audible speech from an audio source;

convert the signal into text;

record the signal of audible speech as a digital audio recording of the audible speech; and

create the trusted speech transcription data record that includes the text and the digital audio recording and to digitally sign the trusted speech transcription data record to securely associate the text with the digital audio recording.

15. The computer program product of claim 14, wherein instructions are further operable to tag the transcription file with metadata associated with the audible speech.

16. The apparatus of claim 15, wherein the metadata comprises one or more of a time stamp, an internet protocol (IP) address of the audio source, an identification of a speaker of the audible speech, or an identifier of the source of the audible speech.

17. The computer program product of claim 14, wherein the instructions are further operable to activate transcription and recording upon detecting a triggering event.

18. The computer program product of claim 17, wherein the triggering event is the reception of a predetermined word or phrase.

19. The computer program product of claim 14, wherein the instructions are further operable to convert the signal of the audible speech and to record the signal representing audible speech substantially in parallel.

20. The computer program product of claim 14, wherein instructions are further operable to record a fragment of the signal representing audible speech and the digital audio recording is a recording of the fragment of the audible speech, the fragment of the audible speech representative of a source of the audible speech.

21. The computer program product of claim 20, wherein the fragment of the audible speech comprises quality characteristics to identify a speaker of the audible speech.

22. The computer program product of claim 20, wherein the fragment of the audible speech is stored with a corresponding transcription of the audible speech.

23. A method comprising:

receiving a signal of audible speech from an audio source;

identifying at least a portion of the audible speech includes identification cues of the identity of a speaker of the audible speech;

converting the signal into text;

recording the signal of audible speech as a digital audio recording of the audible speech; and

creating the trusted speech transcription data record that includes the text and the digital audio recording and to digitally sign the trusted speech transcription data record to securely associate the text with the digital audio recording.

24. The method of claim 23, further comprising starting converting the signal into text and recording the signal of audible speech as a digital audio recording based on receiving a triggering event.

25. The method of claim 23, wherein creating the trusted speech transcription data record comprises digitally signing the trusted speech transcription data record.

26. The method of claim 23, wherein recording the signal of audible speech comprises recording a fragment of the signal representing audible speech and wherein the digital audio recording is a recording of the fragment of the audible speech, the fragment of the audible speech representative of a source of the audible speech and corresponding to the transcribed speech.
