Specifically, a voice collector arranged in the vehicle-mounted computer can collect voice to be recognized sent by a driver and convert the voice to be recognized into a voice signal to be recognized, the vehicle-mounted computer converts the voice signal to be recognized into corresponding driving material information, then the vehicle-mounted computer can send the corresponding driving material information to the vehicle-mounted display screen, and the vehicle-mounted display screen extracts characters or pictures in the driving material information to play after receiving the driving material information.
The process flow shown in fig. 2 will be described in detail below with reference to the specific embodiments, and the contents may be as follows:
In an embodiment, a voice collector is arranged in the vehicle-mounted computer, the voice collector can be a microphone, the voice collector collects voice sent by a driver and converts the voice into an audio signal, the vehicle-mounted computer converts the audio signal into an electric signal to be processed and performs filtering processing on the electric signal to be processed to obtain an electric signal to be recognized (namely, the voice signal to be recognized), and the electric signal to be recognized can be represented as a frequency response curve corresponding to the voice sent by the driver.
Step 202, performing framing processing on the voice signal to be recognized to obtain a plurality of framed feature information.
In an embodiment, the vehicle-mounted computer converts the voice signal to be recognized (frequency response curve) into a digital signal, the digital signal may be a digital string whose frequency response curve changes and is reflected by a change in a value, and the vehicle-mounted computer performs framing processing on the voice signal to be recognized, where the framing processing may be dividing (i.e., framing) the voice signal to be recognized into a plurality of feature information by a minimum value in the digital signal.
Step 203, based on a preset waveform similarity threshold, selecting a pre-stored key feature similar to the feature information waveform to obtain a feature set to be measured.
In an embodiment, after the vehicle-mounted computer divides the speech signal to be recognized into a plurality of feature information, the vehicle-mounted computer pre-stores a standard numeric string (i.e. a key feature) corresponding to a standard pronunciation of a key word, where the key word may be an orientation word, for example: east, south, west, north, etc., may be trigger verbs, such as: on, off, stop, etc., and may also be automotive parts, such as: lights, windows, doors, etc. When the vehicle-mounted computer obtains a plurality of characteristic information, the vehicle-mounted computer can obtain the numeric strings corresponding to the characteristic information. Since each person has a difference in pronunciation of words, the technician sets a waveform similarity threshold in advance in the vehicle-mounted computer. The waveform similarity threshold value can be 10% or 20%, and the vehicle-mounted computer processes each numerical value corresponding to the characteristic information according to the waveform similarity threshold value to obtain an error range corresponding to each numerical value of the numerical string of the characteristic information. For example, when the waveform similarity threshold is set to 20%, a value a is corresponding to a certain time on the numeric string of the selected feature information, and then an error range corresponding to the value a is ax80% -ax120%. The vehicle-mounted computer judges whether each numerical value of the standard numerical string meets the error range of the corresponding moment one by one, when the vehicle-mounted computer identifies that a certain key feature meets all the error ranges corresponding to the numerical string of the feature information, a certain key feature is selected (namely, a pre-stored key feature similar to the waveform of the feature information is selected), and all the obtained key features are arranged to obtain the feature set to be detected.

When the driver stops using one of the operation members, the corresponding cutoff terminal (i.e., the target cutoff terminal) transmits a corresponding cutoff signal (i.e., the target cutoff signal) to the in-vehicle computer. When the vehicle-mounted computer receives the target cut-off signal, the vehicle-mounted computer acquires the driving material information (namely the target driving material information) corresponding to the target cut-off signal. The vehicle-mounted computer is internally provided with a compiler, an ending instruction template is preset in the compiler, and the vehicle-mounted computer adds certain acquired driving material information (namely target driving material information) to the ending instruction template of the compiler and generates a corresponding playing ending instruction (namely a target playing instruction). And the vehicle-mounted computer sends the target playing data instruction to the vehicle-mounted display screen, and the vehicle-mounted display screen terminates displaying the characters or pictures corresponding to the target driving material information after receiving the target playing ending instruction.
