Abstract

A device for automated improvement of digital speech interpretation on a computer system includes: a speech recognizer, configured to recognize digitally input speech; a speech interpreter, configured to accept the output of the speech recognizer as an input, and to manage a digital vocabulary with keywords and their synonyms in a database in order to trigger a specific function; and a speech synthesizer, configured to automatically synthesize the keywords and to feed them to the speech recognizer in order to then insert its output as further synonyms into the database of the speech interpreter if they differ from the keywords or their synonyms.

Claims

1. A device for automated improvement of digital speech interpretation on a computer system, the device comprising:

a speech recognizer, configured to recognize digitally input speech;

a speech interpreter, configured to accept the output of the speech recognizer as an input, and to manage a digital vocabulary with keywords and their synonyms in a database in order to trigger a specific function; and

a speech synthesizer, configured to automatically synthesize the keywords and to feed them to the speech recognizer in order to then insert its output as further synonyms into the database of the speech interpreter if they differ from the keywords or their synonyms.

2. The device according to claim 1, wherein the speech synthesizer is further configured to feed the synthesized synonyms to the speech recognizer in order to enter new synonyms in the database in case of deviations.

3. The device according to claim 1, wherein the speech synthesizer is further configured to synthesize the keywords cyclically using different speech parameters, comprising one or more of the following parameters:

speaker'"'"'s age, speaker'"'"'s sex, speaker'"'"'s accent, speaker'"'"'s pitch, volume, speaker'"'"'s speech impediment, emotional state of the speaker.

4. The device according to claim 1, wherein the speech synthesizer comprises one or more of the following:

a concatenative synthesizer, a parametric synthesizer.

5. The device according to claim 3, wherein the automatic cyclical synthesis of the keywords is dependent on one or more of the following events:

modified keywords, modified synthesizers, expiry of a period of time.

6. A method for automated improvement of digital speech interpretation on a computer system having a speech recognizer which recognizes digitally input speech, a speech interpreter which accepts the output of the speech recognizer as an input and manages a digital vocabulary with keywords and their synonyms in a database in order to trigger a specific function, and a speech synthesizer which automatically converts synthesized keywords into spoken text, the method comprising:

accessing, by the speech synthesizer, the keywords in the database and automatically converting the keywords into spoken language so as to have them recognized by the speech recognizer in order to insert them as further synonyms into the database of the speech interpreter if they differ from the keywords or their synonyms.

7. The method according to claim 6, wherein the speech synthesizer is further configured to feed the speech recognizer with the synthesized synonyms in order to enter new synonyms in the database in the case of deviations.

8. The method according to claim 6, wherein the speech synthesizer is further configured to synthesize the keywords cyclically using different speech parameters, comprising the following parameters:

speaker'"'"'s age, speaker'"'"'s sex, speaker'"'"'s accent, speaker'"'"'s pitch, volume, speaker'"'"'s speech impediment, emotional state of the speaker.

9. The method according to claim 6, wherein the speech synthesizer comprises one or more of the following:

a concatenative synthesizer, a parametric synthesizer.

10. The method according to claim 8, wherein the automatic cyclical synthesis of the keywords is dependent on one or more of the following events:

modified keywords, modified synthesizers, expiry of a period of time.
