Cracking the sound code

Voiceprint refers to the frequency spectrum of sound waves carrying speech information displayed by electroacoustic instruments. It is the key to studying sound codes, determined by factors such as vocal cord vibration frequency and oral shape, and has specific and stable characteristics. Voiceprint recognition technology is widely used in fields such as public safety, financial transactions, and social insurance.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

1. Sound imaging technology is based on microphone array measurement technology, which measures the phase difference of sound waves reaching each microphone in a certain space, determines the position of the sound source based on phased array principle, measures the amplitude of the sound source, and displays the spatial distribution of the sound source in the form of an image, that is, obtaining a spatial sound field distribution cloud image - sound image, where the color and brightness of the image represent the strength. two The principle of speech recognition technology is to enable machines to recognize and convert speech signals into text, and then convert understanding into instructions. three Sound simulation technology, also known as AI voice transformation technology, relies heavily on the support of deep learning and neural networks for its implementation. 4. Voiceprint analysis (identity authentication, health check, emotion analysis, etc.) Voiceprint is the frequency spectrum of sound waves carrying speech information displayed by electroacoustic instruments, consisting of wavelength, frequency, and intensity.
