[0128] First embodiment

[0129] Please refer to figure 1 , Wake-up method flowchart of an embodiment of apparatus of which the present application. The execution subject method include, but are not limited to smart machines story may also be another device having a wake-up function, such as smart speakers, smart video machines, etc. In the present embodiment story machine, for example, the method will be described. In the present embodiment, the method may comprise the steps of:

[0130] Step S101: determining the probability of a wake-word speech frames.

[0131] The machine has a story voice wakeup function, without the user key, to wake up the story of the machine directly by voice. The story machine by a plurality of microphones (microphone array) acquiring the voice data, a voice data may comprise a plurality of speech frames, a 10ms speech frame may be a piece of voice data, each story machine can be sequentially processed speech frame.

[0132] For ease of description, the...

Abstract

The invention discloses an equipment wakeup related system, method, device and equipment. The equipment wake-up method comprises the following steps: determining a wake-up word probability of a previous voice frame; adjusting a filtering coefficient according to the wakeup word probability and the previous voice frame; performing voice enhancement processing on the current voice frame according to the adjusted filter coefficient so as to suppress a human voice noise outside the target sound source in the current voice frame; and recognizing a wakeup word according to the current voice frame after the human voice noise is suppressed so as to adjust the equipment to a wakeup state. By adopting the processing mode, the wakeup feedback of the previous voice frame is combined, and the coefficients of the beam forming filter are updated so that the target voice and the human voice noise can be distinguished, and a reliable noise reduction effect is obtained; and therefore, the wakeup performance of the equipment under highly noisy human voice interference can be effectively improved.

Description

technical field [0001] The present application relates to the field of automation control technology, in particular to a device wake-up system, method and device, voice conference minutes system, method and device, service startup system, method and device, story machine, smart speaker, and electronic equipment. Background technique [0002] In recent years, with the advancement of speech recognition technology, intelligent story machines with voice wake-up function have been widely used. Since the existing acoustic model technology cannot effectively overcome the influence of foam noise and human voice interference, the voice wake-up effect will drop sharply under highly noisy human voice interference. [0003] Signal-to-noise ratio and speech system performance can be greatly improved based on microphone array signal processing technology. Beamforming is a commonly used array signal processing algorithm. It has the advantages of small amount of calculation and easy deploy...
