Abstract

A speech communication system and a method of improving communication in such a speech communication system between at least a first user and a second user may be configured so the system (a) transcribes a recorded portion of a speech communication between the at least first and second user to form a transcribed portion, (b) selects and marks at least one of the words of the transcribed portion which is considered to be a keyword of the speech communication, (c) performs a search for each keyword and produces at least one definition for each keyword, (d) calculates a trustworthiness factor for each keyword, each trustworthiness factor indicating a calculated validity of the respective definition(s), and (e) displays the transcribed portion as well as each of the keywords together with the respective definition and the trustworthiness factor thereof to at least one of the first user and the second user.

Claims

1. A method of using a speech communication system, the speech communication system comprising at least one device having at least one processor communicatively connected to a non-transitory computer readable medium, the method comprising:

a) transcribing, by the system, a recorded portion of a speech communication between at least one first user and at least one second user to form a transcribed portion,

b) selecting and marking, by the system, at least one word of the transcribed portion identified as a keyword of the speech communication,

c) performing, by the system, a search for the keyword and producing at least one definition for the keyword that identifies a meaning of the keyword,

d) calculating, by the system, a trustworthiness factor for each definition for the keyword, each trustworthiness factor indicating a calculated validity of a respective definition for the keyword; and

e) displaying, by the system, the transcribed portion so that the at least one definition of the keyword together with the calculated trustworthiness factor for each definition is displayed in response to a pointer being positioned over the keyword of the displayed transcribed portion or selection of the keyword of the displayed transcribed portion.

2. The method of claim 1, wherein each definition is a generated dictionary definition and wherein the system calculating the trustworthiness factor comprises:

the system performing;

a semantic search using taxonomies in order to generate a taxonomy correction factor for determining the trustworthiness factor for each definition;

a similarity checking which takes into account similarity of different definitions for the keyword in order to generate a similarity correction factor for determining the trustworthiness factor for each definition; and

a sentiment detection which takes into account sentiment with respect to a definition for the keyword to generate a sentiment correction factor for determining the trustworthiness factor for that definition; and

determining the trustworthiness factor for each definition based on the taxonomy correction factor, the similarity correction factor, and the sentiment correction factor for the keyword; and

wherein the system performing the search for the keyword comprises;

the system communicating with at least one information space communicatively connected to the system via at least one network connection to identify at least one definition for the keyword for producing a definition for the keyword.

3. The method of claim 1, comprising:

performing a spell-check of the transcribed portion using at least one regular glossary and/or at least one domain glossary.

4. The method of claim 1, wherein:

step b) comprises an automatic selecting of keywords by the system and manually selecting of keywords by a user and/or by a community of users using the system.

5. The method of claim 1, wherein:

step c) comprises a search in a structured and/or in an unstructured data repository.

6. The method of claim 1, wherein:

step d) comprises the system performing a semantic search using ontologies.

7. The method of claim 1, wherein:

step d) comprises the system performing a semantic search using taxonomies in order to generate a taxonomy correction factor for modifying the trustworthiness factor.

8. The method of claim 1, wherein:

step d) comprises the system carrying out similarity checking which takes into account similarity of different definitions of the keyword in order to generate a similarity correction factor for modifying the trustworthiness factor.

9. The method of claim 1, wherein:

step d) comprises the system carrying out sentiment detection which takes into account the sentiment with respect to at least one definition of the keyword in order to generate a sentiment correction factor for modifying the trustworthiness factor.

10. The method of claim 1, wherein the speech communication results in a communication thread and wherein a glossary of the communication thread is created and regularly updated.

11. A non-transitory tangible computer-readable medium comprising a computer program that defines a method that is performed by a communication system when a processor of the system runs the program, the method comprising:

a) transcribing, by the system, a recorded portion of a speech communication between at least one first user and at least one second user to form a transcribed portion,

b) selecting and marking, by the system, at least one word of the transcribed portion identified as a keyword of the speech communication,

c) performing, by the system, a search for the keyword and producing at least one definition for the keyword that identifies a meaning of the keyword,

d) calculating, by the system, a trustworthiness factor for each definition for the keyword, each trustworthiness factor indicating a calculated validity of a respective definition for the keyword; and

e) displaying, by the system, the transcribed portion so that the at least one definition of the keyword together with the calculated trustworthiness factor for each definition is displayed in response to a pointer being positioned over the keyword of the displayed transcribed portion or selection of the keyword of the displayed transcribed portion.

12. A speech communication system comprising:

a non-transitory computer readable medium;

a transcription unit, the transcription unit configured to transcribe a recorded portion of a speech communication between at least a first user and a second user stored in the non-transitory computer readable medium to form a transcribed portion,

a selecting unit, the selecting unit configured to select and mark at least one of the words of the transcribed portion which is considered to be a keyword of the speech communication,

a search unit, the search unit configured to perform at least one search for the keyword and produce at least one definition for the keyword that identifies a meaning of the keyword,

a trustworthiness unit, the trustworthiness unit configured to calculate a trustworthiness factor for the keyword, each trustworthiness factor indicating a calculated validity of a respective definition for the keyword; and

a display unit, the display unit configured to display the transcribed portion such that, in response to a pointer being positioned over the keyword of the displayed transcribed portion or selection of the keyword, displaying of the at least one definition of the keyword together with the calculated trustworthiness factor for each displayed definition is actuated.

13. The speech communication system of claim 12, further comprising:

a recording unit, the recording unit configured to record real-time speech communication.

14. The speech communication system of claim 13, further comprising:
