Abstract

In a non-manual method and system for monitoring speech-controlled applications, a speech data stream of a user is acquired by a microphone and the speech data stream is analyzed by a speech recognition unit for the occurrence of stored key terms. An application associated with the key term is activated or deactivated upon detection of a key term within the speech data stream.

Claims

1. A method for monitoring speech-controlled applications comprising the steps of:

acquiring a speech data stream with a microphone;

electronically examining said speech data stream to identify an occurrence of a term therein corresponding to a stored key term;

upon detection of a term in said speech data stream corresponding to a stored key term, implementing an action, selected from activation and deactivation, of a speech-controlled application associated with the stored key term; and

electronically forwarding said speech data stream to a unit for implementing the speech-controlled application for processing in said unit according to said action

2. A method as claimed in claim 1 comprising, before electronically analyzing said speech data stream, subjecting said speech data stream to at least one electronic voice detection check to determine whether said speech data stream originated from an authorized person, and electronically analyzing said speech data stream only if said speech data stream is determined to originate from an authorized person.

3. A method as claimed in claim 1 comprising, before implementing said action, electronically generating a humanly-perceptible query, and implementing said action only after electronically detecting a manual response to said query.

4. A method as claimed in claim 1 wherein the step of implementing said action comprises electronically consulting a set of stored decision rules to determine whether a previously-active one of said speech-controlled applications should be deactivated or left in an active state.

5. A method as claimed in claim 1 comprising, in said unit for implementing said speech-controlled application, electronically examining said speech data stream to identify a presence of a command therein corresponding to an application-specific stored command, and if a command corresponding to a stored command is present in said speech data stream, triggering a command action associated with said stored command.

6. A system for monitoring speech-controlled applications comprising:

a microphone that acquires a speech data stream;

a speech recognition unit that electronically examines said speech data stream to identify an occurrence of a term therein corresponding to a stored key term;

a decision module that, upon detection of a term by said speech recognition unit in said speech data stream corresponding to a stored key term, generates an output to implement an action, selected from activation and deactivation, of a speech-controlled application associated with the stored key term; and

an application manager that electronically forwards said speech data stream and said decision module output to an application unit for implementing the speech-controlled application for processing in said application unit according to said action.

7. A system as claimed in claim 6 comprising a voice recognition unit connected between said microphone and said speech recognition unit, that subjects said speech data stream to at least one electronic voice detection check to determine whether said speech data stream originated from an authorized person, and passes said speech data stream to said speech recognition unit only if said speech data stream is determined to originate from an authorized person.

8. A system as claimed in claim 6 wherein said application unit, before implementing said action, electronically generates a humanly-perceptible query, and implementing said action only after electronically detecting a manual response to said query.

9. A system as claimed in claim 6 wherein the decision module electronically consults a set of stored decision rules to determine whether a previously-active one of said speech-controlled applications should be deactivated or left in an active state.

10. A system as claimed in claim 6 comprising, in said application unit for implementing said speech-controlled application, electronically examining said speech data stream to identify a presence of a command therein corresponding to an application-specific stored command, and if a command corresponding to a stored command is present in said speech data stream, triggering a command action associated with said stored command.
