Abstract
A method of detecting singing of a user of a personal audio device, the method comprising: receiving a first audio signal comprising bone-conducted speech of the user from a first transducer of the personal audio device; monitoring a second audio signal output to a speaker of the personal audio device; and determining whether the user is singing based on the first audio signal and the second audio signal.
Claims25
A method of detecting singing of a user of a headset, the method comprising:
- receiving a first audio signal comprising bone-conducted speech of the user from a first transducer of the headset;
- monitoring a second audio signal output to a speaker of the headset;
- determining whether the user is singing based on the first audio signal and the second audio signal;
- and
- on determining that the user is singing, enabling feedback active-noise cancellation (ANC) in the headset.
An apparatus for detecting singing by a user of a headset, the apparatus comprising:
- an input for receiving a first audio signal comprising bone-conducted speech of the user from a first transducer of the headset;
- one or more processors configured to:
- monitor a second audio signal output to a speaker of the headset;
- determine whether the user is singing based on the first audio signal and the second audio signal;
- and
- on determining that the user is singing, enable feedback active-noise cancellation (ANC) in the headset.
A method of detecting singing of a user of a personal audio device, the method comprising:
- receiving a first audio signal comprising bone-conducted speech of the user from a first transducer of the personal audio device;
- monitoring a second audio signal output to a speaker of the personal audio device;
- determining a speech articulation rate of speech in the first audio signal;
- comparing the speech articulation rate with an expected speech articulation rate of the user;
- and
- determining whether the user is singing based on comparison and the second audio signal.
