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.
Claims21
A method for determining a relative position of a microphone, the method comprising:
- capturing speech audio from a user's mouth with the microphone so that the microphone outputs an electrical signal indicative of the speech audio;
- a computer deriving a plurality of inputs from the electrical signal;
- determining an indication of a position of the microphone relative to the user's mouth, comprising providing to a discriminative classifier implemented on the computer at least the plurality of inputs and at least some contextual data;
- the computer receiving an output from the discriminative classifier, the output providing an indication of the position of the microphone relative to the user's mouth derived by the discriminative classifier based at least in part on the plurality of inputs and the contextual data;
- and
- the computer determining whether the indicated position of the microphone is unacceptable at least in part by comparing the indicated position to a value or range, and providing a signal to a user if the indicated position of the microphone is unacceptable.
A method for determining a relative position of a microphone, the method comprising:
- 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, comprising providing a plurality of inputs to a computerized discriminative classifier, 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;
- and
- an output from the computerized discriminative classifier is indicative of the position of the microphone relative to the user's mouth, the output derived at least in part from the plurality of inputs.
A method for determining a relative position of a microphone, the method comprising:
- providing a plurality of inputs to a discriminative classifier implemented on a computer, the plurality of inputs comprising data:
- (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 computer receiving an output from the discriminative classifier, the output providing an indication of the position of the microphone relative to the user's mouth, the indication based at least in part on the plurality of inputs;
- and
- the computer determining whether the indicated position of the microphone is unacceptable at least in part by comparing the output from the discriminative classifier to a value or range, and providing a signal if the indicated position of the microphone is unacceptable.
