[0085] Figure 5 A flowchart of an imaging display method provided in an embodiment of the present application is shown, wherein the imaging display method is executed in the processor of the imaging display device described above. Figure 5 As shown, the imaging display method is implemented by the following steps:

[0086] Step 501: After acquiring a voice signal through the audio receiving device, the voice signal is framed to obtain a plurality of voice segments.

[0087] Step 502: for each of the voice segments, the voice segment is processed using the following formula 1 to obtain the voice to be processed:

[0088] Sω(n) = s(n) × ω(n); (Formula 1)

[0089] Among them, s(n) is the speech segment, and ω(n) is the window function.

[0090] Step 503: for each speech segment corresponding to the speech to be processed, determine the frequency domain signal of the speech to be processed using the following formula 2:

[0091]

[0092] Among them, x[n] is the time domain signal corresponding to the currently processed speech to be processed, N is the number of sampling points of the currently processed speech to be processed, n is the sampling sequence number of the time domain signal, k is the sampling sequence number of the currently processed speech to be processed in the frequency domain, j is an imaginary number satisfying j2=-1, e is the base of the natural logarithm, and π is an irrational number.

[0093] Step 504: After obtaining the frequency domain signal corresponding to each speech to be processed, for each frequency domain signal, the frequency spectrum amplitude corresponding to each speech to be processed is obtained using the following formula 3:

[0094]

[0095] Among them, || represents modulo, Re is the real part of the frequency domain signal, and Im is the imaginary part of the frequency domain signal.

[0096] Step 505: Map each spectrum amplitude to a two-dimensional space with time as the horizontal axis and the number of frequency components as the vertical axis according to the time position and the number of frequency components of the speech to be processed in the speech signal corresponding to each spectrum amplitude, to obtain a two-dimensional image.

[0097] Step 506: normalize each spectrum amplitude integer to 0-255 to obtain a normalized value corresponding to each spectrum amplitude.

[0098] Step 507: Determine the hue value of each normalized value according to the following formula 4:

[0099] T = (A / 255) * 360; (Formula 4)

[0100] Among them, A is the normalized value.

[0101] Step 508: Determine the RGB value corresponding to each hue value according to the mapping relationship between the hue value and the RGB value.

[0102] Step 509, assigning colors to corresponding positions in the two-dimensional image according to the obtained RGB values, and controlling the screen to generate a color image according to the two-dimensional image after the colors are assigned, so that the color image passes through the light-transmitting hole and is refracted by the beam splitter film and then forms an image on the regular hexahedron.

[0103] Specifically, the speech signal is a nonlinear, non-stationary, time-varying random signal, but it can be regarded as stationary and time-invariant in a short time. Therefore, after obtaining the speech signal, the speech signal is framed according to a preset time length to obtain multiple speech segments. This can make the characteristics of the signal in each frame relatively stable. After framing, there will be discontinuities at the beginning and end of each speech segment. Therefore, the more speech segments are segmented, the greater the error with the original speech signal. In order to solve this problem, the speech segments after framing become continuous, and each speech segment will exhibit the characteristics of a periodic function. It is necessary to apply a window function to each speech segment, such as a rectangular window, a Hamming window, a Hanning window, etc. The window function is a sequence of a finite length, and its length is the same as the length of the speech segment.

[0104] Since the frequency domain amplitude can reflect various voice characteristics of the user, including energy distribution, resonance peak characteristics, pitch and sound quality, voice emotion and state, etc., these characteristics are of great significance for applications in the fields of speech processing, speech recognition, and speech analysis. Therefore, in order to better analyze each voice segment, the frequency domain signal corresponding to each voice segment is obtained by formula 2, and then the corresponding spectrum amplitude is obtained by formula 3, wherein the value of the above e is approximately 2.71828, and the value of π is approximately 3.14159.

[0105] Since each speech segment corresponds to a different time period, and different speech segments have different numbers of frequency components, and since the number of frequency components can characterize multiple features of the speech segment, such as complexity and clarity, in order to construct an image that matches the current user's speech signal, a two-dimensional coordinate system can be constructed with time as the horizontal axis and the number of frequency components as the vertical axis. Then, each speech segment is projected into the two-dimensional coordinate system according to the time corresponding to each speech segment and the number of frequency components of the corresponding spectrum amplitude, thereby obtaining a two-dimensional image composed of multiple points.

[0106] In order to obtain a colored image, each spectrum amplitude integer can be normalized to 0-255, for example: a value greater than 255 is normalized to 255. If it is a non-integer, the corresponding integer is obtained by rounding, that is, the normalized value. Then the normalized value is mapped to the hue value through formula 4, and the RGB value corresponding to each hue value is determined according to the preset mapping relationship between the hue value and the RGB value. Then the obtained RGB value is assigned to the corresponding position, so that each point on the above-obtained two-dimensional image has a color, so that a color image can be obtained. In order to prevent the colors between adjacent positions in the color image from being abrupt, continuous and smooth colors can be used to transition between adjacent positions. A color image can be obtained by the above method, and then the screen is controlled to perform imaging, and after passing through the light-transmitting hole, it is refracted by the dichroic film and then imaged on the regular hexahedron.

[0107] In a feasible implementation manner, after the speech signal is framed, the length of each speech segment is 20 milliseconds to 30 milliseconds.

[0108] In a feasible implementation manner, the window function is a Hamming window.
