Description

technical field [0001] The invention relates to the technical field of intelligent voice recognition, in particular to a head-mounted intelligent voice recognition device. Background technique [0002] Speech recognition technology, also known as automatic speech recognition, converts human speech into electrical signals for input. The speech recognition module in the intelligent speech recognition device includes a speech recognition chip and other auxiliary circuits. However, it is difficult to have a completely quiet voice interaction place in the existing environment. Therefore, noise reduction processing is often required after voice pickup to filter the noise collected during the sound test to prevent the accuracy of voice recognition from being affected. Generally, the noise reduction processing device is relatively complicated, and it is necessary to separate the voices of different frequencies, which will greatly increase the production cost and reduce the profit ma...

[0002] Speech recognition technology, also known as automatic speech recognition, converts human speech into electrical signals for input. The speech recognition module in the intelligent speech recognition device includes a speech recognition chip and other auxiliary circuits. However, it is difficult to have a completely quiet voice interaction place in the existing environment. Therefore, noise reduction processing is often required after voice pickup to filter the noise collected during the sound test to prevent the accuracy of voice recognition from being affected. Generally, the noise reduction processing device is relatively complicated, and it is necessary to separate the voices of different frequencies, which will greatly increase the production cost and reduce the profit margin of the product.

[0003] In addition, when collecting voices, due to the different sound frequencies of high, middle and low sounds, male audio is generally 82~698HZ, and female audio is generally 82~1100HZ. Generally speaking, the range of high and low sounds is in a large fluctuation range. , so the manufacturing accuracy of the detection device is high, which increases the cost of the enterprise, and cannot accurately pick up sound in a noisy environment, and the applicable scene is limited. , it is easy to cause recognition errors
