Abstract
According to examples, an apparatus may include a processor and a non-transitory computer readable medium on which is stored instructions that the processor may execute to access an audio signal captured by a microphone of a user's speech while the microphone is in a muted state. The processor may also execute the instructions to analyze a spectral or frequency content of the accessed audio signal to determine whether the user was facing the microphone while the user spoke. In addition, based on a determination that the user was facing the microphone while the user spoke, the processor may execute the instructions to unmute the microphone.
Claims15
An apparatus comprising:
- a processor;
- and
- a non-transitory computer readable medium on which is stored instructions that when executed by the processor, cause the processor to:
- access an audio signal captured by a microphone of a user's speech while the microphone is in a muted state;
- analyze a frequency content of the captured audio signal to determine whether the user was facing the microphone while the user spoke, by determining whether the frequency content of the captured audio signal is higher than a threshold frequency;
- and
- in response to a determination that the user was facing the microphone while the user spoke based on a determination that the frequency content of the captured audio signal is higher than the threshold frequency, unmute the microphone.
A non-transitory computer readable medium storing machine readable instructions that when executed by a processor cause the processor to:
- access an audio signal captured by a microphone of a user's speech while the microphone is in a muted state;
- analyze a frequency content of the captured audio signal to determine whether the user was facing the microphone while the user spoke, by determining whether the frequency content of the captured audio signal is higher than a threshold frequency;
- and
- in response to a determination that the user was facing the microphone while the user spoke based on a determination that the frequency content of the captured audio signal is higher than the threshold frequency, unmute the microphone.
A method comprising:
- accessing, by a processor, an audio signal captured by a microphone of a user's speech while the microphone is in a muted state;
- analyzing, by the processor, a frequency content of the captured audio signal to determine whether the user was facing the microphone while the user spoke, by determining whether the frequency content of the captured audio signal is higher than a threshold frequency;
- and
- in response to a determination that the user was facing the microphone while the user spoke based on a determination that the frequency content of the captured audio signal is higher than the threshold frequency, unmuting, by the processor, the microphone.
