1. A voice messaging system for converting an audio voice message from a caller to text, the voice messaging system comprising:
- a plurality of conversion resources for converting the audio voice message into the text for an intended recipient, the plurality of conversion resources comprising;
at least one automatic speech recognition (ASR) system to automatically recognize at least some of the audio voice message to convert, at least in part, the audio voice message into the text;
a computer implemented call-pair sub-system configured to use call-pair history information based on at least one previous communication between the caller and the recipient to improve conversion accuracy of the ASR system in converting the audio voice message to the text, wherein the call-pair history information includes at least one word or phrase used by the caller or the intended recipient in a previous communication to form a grammar to improve the conversion accuracy of the ASR system in converting the audio voice message to the text; and
a text output device configured to output the text.

Abstract
A mass-scale, user-independent, device-independent, voice messaging system that converts unstructured voice messages into text for display on a screen is disclosed. The system comprises (i) computer implemented sub-systems and also (ii) a network connection to human operators providing transcription and quality control; the system being adapted to optimize the effectiveness of the human operators by further comprising 3 core sub-systems, namely (i) a pre-processing front end that determines an appropriate conversion strategy; (ii) one or more conversion resources; and (iii) a quality control sub-system.

19. A method for converting an audio voice message from a caller, to a recipient, to text, the method comprising:
-
automatically recognizing, using at least one processor configured to perform automatic speech recognition, at least some of the audio voice message to convert, at least in part, the audio voice message into the text; using, by the at least one processor, call-pair history information based on at least one previous communication between the caller and the recipient to improve conversion accuracy of the ASR system in converting the audio voice message to text, wherein the call-pair history information includes at least one word or phrase used by the caller or the recipient in a previous communication to form a grammar to improve the conversion accuracy of the ASR system in converting the audio voice message to the text; and outputting the text. - View Dependent Claims (20)

21. At least one computer readable storage device for storing instructions that, when executed on at least one computer, performs a method for converting an audio voice message from a caller, to a recipient, to text, the method comprising:
-
automatically recognizing at least some of the audio voice message to convert, at least in part, the audio voice message into the text; using call-pair history information based on at least one previous communication between the caller and the recipient to improve conversion accuracy of the ASR system in converting the audio voice message to text, wherein the call-pair history information includes at least one word or phrase used by the caller or the recipient in a previous communication to form a grammar to improve the conversion accuracy of the ASR system in converting the audio voice message to the text; and outputting the text. - View Dependent Claims (22, 23)
