Embodiment 1

[0048] In an embodiment of the present invention, a speech recognition method is provided, such as figure 1 shown, including the following steps:

[0049]S100: collecting the first sound source, the bone conduction microphone collects the voice of the user; specifically, the bone conduction microphone 10 only collects the voice of the user (ie the user);

[0050] S200: The second sound source is collected, and the air conduction microphone collects the surrounding sound; specifically, the air conduction microphone 20 can collect the surrounding environment within the range that the air conduction microphone 20 can collect except for the voice of the user (that is, the user). other voices of

[0051] S300: Sound source transmission, both the first sound source and the second sound source are converted into electrical signals and then transmitted to the processor;

[0052] S400: Sound source identification, the processor identifies the electrical signal of the second sound sou...

Embodiment 2

[0074] In the embodiment of the present invention, such as figure 2 As shown, a noise identification method is provided, comprising the following steps:

[0075] S100: collecting the first sound source, the bone conduction microphone collects the vibration sound of the device, and the device in this embodiment is a car;

[0076] S200: The second sound source acquisition, the air conduction microphone collects the sound around the device, that is, the sound inside the car;

[0077] S300: Sound source transmission, both the first sound source and the second sound source are converted into electrical signals and then transmitted to the processor;

[0078] S400: Sound source identification, the processor identifies the electrical signal of the first sound source according to the electrical signal of the second sound source.

[0079] In the embodiment of the present invention, the bone conduction microphone 10 collects the vibration sound of the car, including the noise generate...

Embodiment 3

[0082] In the embodiment of the present invention, such as image 3 As shown, a sound pickup device is also provided, including bone conduction microphone 10, air conduction microphone 20 and processor 30; The electrical sound signals collected by the conduction microphone 10 and the air conduction microphone 20 are processed; through the combined use of the bone conduction microphone 10 and the air conduction microphone 20, the processor 30 processes the collected electrical signals, and the sound collected by the bone conduction microphone 10 is clear , The sound collected by the air conduction microphone 20 is less distorted, and the characteristics of the bone conduction microphone 10 and the air conduction microphone 20 complement each other to obtain a high-quality call noise reduction and active noise reduction experience. The processor 30 belongs to the prior art and is well known to those skilled in the art, so it is not described here.

Abstract

The invention belongs to the field of acoustoelectric technologies, and particularly relates to a speech recognition method, a noise recognition method, a sound pickup device and communication equipment. The speech recognition method comprises the following steps: S100: a bone conduction microphone collects the speaking sound of a user; S200, an air conduction microphone collects surrounding sounds; S300, a first sound source and a second sound source are both converted into electric signals, and the electric signals are transmitted to a processor; S400, the processor identifies the electric signal of the second sound source according to the electric signal of the first sound source; and the bone conduction microphone and the air conduction microphone are matched to collect sound, and thecollected sound is transmitted to the processor for processing to recognize the needed sound.

Description

technical field [0001] The invention belongs to the technical field of sound and electricity, and in particular relates to a speech recognition method, a noise recognition method, a sound pickup device and a communication device. Background technique [0002] At present, most communication devices such as mobile phones and earphones use air-conduction microphones to collect sound frequencies through the propagation of sound in the air to achieve the functions of recording and calling. Headphones and mobile phones on the market adopt a dual-mic noise reduction solution. Dual-mic noise reduction means that one microphone collects the voice of people speaking, and the other microphone collects the sound of the surrounding environment. The sound of the surrounding environment is collected and processed by a noise reduction algorithm to reduce surrounding noise and The noisy environment makes the call clearer; however, the dual-mic noise reduction solution still has the problems ...
