Title: Earbud speech estimation
Inventor: DAVID LEIGH WATTS
IPC: H04R1/46
Filed: 2018-06-15
Abstract: Earbud speech estimation comprising: receiving bone conduction (BC) sensor 230 and microphone 210 input signals; a processor 220 to determine at least one non-binary speech characteristic from the bone conduction sensor signal. The processor further deriving a conditioning parameter from the speech characteristic to condition the microphone signal; the non-binary variable speech characteristic is a speech estimate. The microphone signal conditioning may be irrespective of voice activity, based only upon speech characteristics, and apply noise reduction or a Kalman filter. The non-binary speech characteristic may be a speech level, an observed spectrum, a spectral envelope representation, or a SNR ratio of the BC sensor signal. The conditioning parameter may comprise band-specific gains. A speech estimate may modify a weighting factor for a casual recursive speech enhancement (CRSE). Only the speech characteristic of the BC sensor signal may be passed to the earbud (120, 130) which may be wireless. Before the speech characteristic is determined the BC sensor signal may be corrected. The BC sensor may comprise an in-ear microphone and an accelerometer. A filter may match the BC sensor signal user’s speech to the microphone signal. A method and a non-transitory computer readable medium are also claimed.
