1. An apparatus comprising:
- at least one processor; and
at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least;
receive a signal from a headset;
derive a plurality of inputs from the signal to determine an approximate position of a microphone relative to a user'"'"'s mouth;
process, using a discriminative classifier that comprises a model derived from at least one of training data and test data, wherein the at least one of the training data and the test data comprise a measured actual position of a microphone relative to the user'"'"'s mouth, the plurality of inputs and a contextual data to determine a derived value of the approximate position of the microphone relative to the user'"'"'s mouth, wherein the contextual data is representative of conditions occurring at a time when speech audio is captured by the microphonedetermine whether the derived value of the approximate position of the microphone is unacceptable based on a comparison of the derived value and at least one of a value and a range values indicative of the microphone being an acceptable distance relative to the user'"'"'s mouth; and
provide a signal to a user if the derived value of the approximate position of the microphone is unacceptable.

Abstract
A method for determining a relative position of a microphone may include capturing speech audio from a user'"'"'s mouth with the microphone so that the microphone outputs an electrical signal indicative of the speech audio; determining an indication of a position of the microphone relative to the user'"'"'s mouth, which may include providing a plurality of inputs to a computerized discriminative classifier, wherein an input of the plurality of inputs is derived from the electrical signal, and wherein an output from the computerized discriminative classifier is indicative of the position of the microphone relative to the user'"'"'s mouth.

9. A system comprising:
-
a microphone, wherein the microphone captures speech audio from a user'"'"'s mouth and outputs an electrical signal indicative of the speech audio; a computer and a storage device storing instructions that are operable, when executed by the computer, to cause the computer to output, using a discriminative classifier that comprises a model derived from training data and/or test data, the training data and/or the test data comprising a manually measured actual position of a microphone relative to a user'"'"'s mouth, a derived value of the approximate position of the microphone relative to the user'"'"'s mouth, the operations comprising; receiving an electrical signal transmitted by the microphone; determining a plurality of inputs from the electrical signal, wherein a first input of the plurality of inputs is derived from the electrical signal, and a second input of the plurality of inputs comprises contextual data, the contextual data representative of conditions occurring at a time when the speech audio is captured; and outputting the derived value of the approximate position of the microphone relative to the user'"'"'s mouth, the output derived at least in part from the plurality of inputs. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A system to determine a relative position of a microphone, the system comprising:
-
a discriminative classifier, implemented on a computer, that is configured to receive a plurality of inputs, the discriminative classifier comprising a model derived from training data and/or test data, the training data and/or the test data comprising a manually measured actual position of a microphone relative to a user'"'"'s mouth, and the plurality of inputs comprising;
(i) an electrical signal output from the microphone in response to the microphone capturing speech audio from a user'"'"'s mouth while the microphone is at a position relative to the user'"'"'s mouth, and/or data derived from the electrical signal; and
(ii) contextual data, the contextual data originating and/or representing conditions occurring at a time when the speech audio is captured;wherein the discriminative classifier is further configured to provide a derived value of an approximate position of the microphone relative to the user'"'"'s mouth, the derived value based at least in part on the plurality of inputs, wherein the derived value is processed by the computer to determine if the approximate position of the microphone unacceptable at least in part by comparing the derived value output from the discriminative classifier to a value or range indicative of the microphone being an acceptable distance relative to the user'"'"'s mouth. - View Dependent Claims (20)
