In this embodiment, the sensing module records the pronunciation action parameters and the voice waveforms of the continuous speech stream of the Chinese speaker by using Wave System equipment of NDI corporation, and prepares the EMA database of the Chinese continuous speech stream through preprocessing, because the EMA parameters are position information directly recorded by the EMA sensor.
As shown in fig. 7, UL denotes the upper lip, LL denotes the lower lip, J denotes the lower palate, T3 denotes the tongue tip, T2 denotes the tongue middle, and T1 denotes the tongue back.
Before HMM modeling is carried out on EMA parameters, preprocessing is carried out, the preprocessing is mainly divided into two steps of head movement regularization and occlusal surface regularization, the head movement regularization is the position information of a pronunciation organ relative to a fixed reference System recorded by original EMA data, and the actually interesting information is the movement information of the pronunciation organ relative to the head of a speaker, so the EMA data are regularized to eliminate the influence of the head movement, a 6D reference sensor provided by NDI public Wave System is adopted, the reference sensor is placed at the bridge of the nose of the speaker (the bridge is considered to be kept relatively static with the head all the time during pronunciation), the EMA data of other sensor pronunciation organs relative to the head of the sensor can be obtained conveniently, and the occlusal surface regularization is that a plane formed when teeth of the speaker are naturally occluded is defined as an occlusal surface, three sensors A, B and C (a straight line AB is vertical to BC) are arranged on a hard board, so that a speaker naturally bites the hard board to measure the occlusal surface of the speaker, the occlusal surface normalization is to convert an original xyz coordinate system taking a nose bridge reference point as a center into an x ' y ' z ' coordinate system, wherein an x ' y ' plane is an occlusal surface, a y ' z ' plane is a head middle axial surface vertical to the occlusal surface, the speaker action parameters can be more obvious in physical significance by utilizing the occlusal surface to normalize the speaker action parameters, comparability of different speaker EMA parameters can be better ensured, EMA data with normalized head movement is completed, each sensor respectively has x, y and z three-dimensional data, wherein x represents left-right direction displacement, y represents front-back direction displacement, z represents up-down direction displacement, the M point is a required point, and T is the projection of the point M on the occlusal surface, s is the foot of TS on the straight line BC. Taking the length of MT, TS as the modulus of z ', y ', the modulus of x ' is small and negligible since all sensors are placed on the axial plane in the head of the speaker. And if the Y sign information is determined by the normal vector of BM and occlusal surface and the included angle of AB straight line, EMA data corresponding to each sensor is reduced from three-dimension to two-dimension through occlusion surface regulation.
The pronunciation action parameter prediction method comprises two parts of training and prediction, and a group of context-dependent HMM models lambda are obtained by maximizing the joint distribution likelihood function P (X, Y | lambda) of the acoustic and pronunciation action parameters in the training process, wherein
And
represents a sequence of observations of vocal action features and acoustic features of parallel length N (·)TThe expression matrix is transposed, and each frame of pronunciation action characteristic observation vector chit∈R3Dx, acoustic feature observation vector yt∈R3Dy contains static parameters
As well as first and second order differences thereof, as shown below.
After initializing context-dependent HMM training, training a decision tree by using a minimum description length criterion and a context attribute problem set, clustering the HMM by using the decision tree, thus solving the over-fitting problem caused by data sparseness, when performing model clustering based on the decision tree on pronunciation action parameters and acoustic parameters, respectively constructing decision trees (independent clustering) for the two parameters, or constructing a shared decision tree (shared clustering) for the two parameters, then performing state segmentation by using the context-dependent HMM obtained by training and training a state duration probability model, through the training process, the model obtained by final training comprises the clustering HMM of spectrum, fundamental frequency, duration and pronunciation action parameters and respective decision trees, in the prediction process, firstly determining an HMM sequence by using a result obtained by front-end text analysis and the decision trees, then, the optimal pronunciation action parameters are generated by using the MLPG algorithm as follows
In the formula
Static parameters are parameters of pronunciation action.

The power supply pin is connected to the working power supply of the microcontroller, VCC is +5V power supply and ground, GND is ground, the clock pins XTAL1 and XTAL2 are respectively the input end and the output end of the on-chip oscillator inverting amplifier and the clock generator circuit, when the oscillator runs, the reset RST resets when the pin has a high level more than two machine periods (24 oscillation periods), the single chip microcomputer resets, and the chip resets circularly as long as the pin is kept in the range of the high level.
The single chip microcomputer has 5 interrupt vectors which are 2 external interrupts (INT0 and NT1), 2 timing interrupts (Timer0 and Timer1) and a serial interrupt, wherein the interrupt vector is actually an address of a program memory and indicates that an interrupted service program is stored from the beginning, and after the interrupt occurs, a CPU is guided to turn to corresponding interrupt service through the interrupt vector, the interrupt vector is called as an interrupt vector because of the directivity, and the interrupt request in a level mode is effective at a low level. As long as the single chip microcomputer samples an effective low-level signal at the interrupt request leading-in end, namely the interrupt request, the interrupt request in the pulse mode is that the falling edge of the pulse is effective. In two sampling of two adjacent machine periods, if the former time is high and the latter time is low, the interrupt request signal is obtained, for this reason, the high and low level states of the interrupt request signal in the pulse mode should be maintained for at least one machine period to ensure that the jump of the negative pulse can be sampled, and the timer interrupt is set for meeting the requirements of timing or counting. The single chip has 2 timers and counters T0 and T1 inside, so timer interrupt also has 2 timers 1 interrupt and timer0 interrupt, when the counter is out, the timer time is up or the count value is full, this is that the internal circuit generates the interrupt request, because the interrupt request is generated inside the chip, there is no corresponding interrupt request lead-in end on the chip.
