Adjustable microphone headset

An adjustable headset comprising:

• a microphone located at a first position, wherein the microphone is configured to receive a speech signal input from a user in the form of an utterance;
• a computing device, wherein the computing device is configured to:
• determine a pass state or a fail state of the first position of the microphone, based upon a comparison of a feedback parameter with a feedback threshold, and, if a fail state is determined, to calculate a second position of the microphone;
• determine a feedback parameter, in response to the speech signal input, wherein the feedback parameter comprises a confidence parameter defining an average recognition score of the speech signal input that matches a desired output and a vocabulary assistance parameter defining a number of times that the speech signal input is recognized due to vocabulary approximation;
• modify the feedback parameter, in response to the speech signal input, to further comprise a node exit attempt parameter defining a number of attempts required for a user to exit a particular node in a vocabulary task map;
• and
• a stepper motor configured to move the microphone from the first position to the second position.

A computer program product comprising at least one non-transitory computer-readable storage medium having computer-executable program code stored therein, the computer-executable program code comprising program code instructions configured to:

• detect a microphone at a first position;
• receive a speech signal input from a user in the form of an utterance;
• determine, in response to the speech signal input, a feedback parameter, wherein the feedback parameter comprises:
• a confidence parameter defining an average recognition score of the speech signal input that match a desired output,
• a vocabulary assistance parameter defining a number of times that the speech signal input is recognized due to vocabulary approximation, and
• a node exit attempt parameter defining a number of attempts required for a user to exit a particular node in a vocabulary task map;
• determine a pass state in an instance in which the feedback parameter satisfies a feedback threshold, to maintain the microphone at the first position;
• and
• determine a fail state in an instance in which the feedback parameter fails to satisfy a feedback threshold, to cause a stepper motor to move the microphone from the first position to a second position.
