Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be described in detail technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments; Based on the embodiment in the utility model, those of ordinary skill in the art belong to the scope of the utility model protection not making the every other embodiment obtained under creative work prerequisite.
As shown in Figure 1, there is shown a kind of speech control system of automobile trunk, comprise automobile trunk electromagnetic valve 33, ECU ECU10.
ECU ECU10 comprises universal input module 11, A/D modular converter 12, compares output module 13, sound bank memory module 14, D/A modular converter 15 and general output module 16.
Input module 11 is connected with system switching 21 and input through keyboard module 22, and input module 11 receives the input signal from system switching 21 and input through keyboard module 22; A/D modular converter 12 is connected with Audio Input Modules 23, and the phonetic order audio signal of driver is converted into voltage spectrum signal by Audio Input Modules 23, and the voltage spectrum signal of Audio Input Modules 23 is converted into voice digital signal by A/D modular converter 12; Compare the algorithm that output module 13 utilization itself stores, by comparing the similarity from the voice digital signal of A/D modular converter 12 and the voice digital signal of sound bank memory module 14, the phonetic order of driver is identified, form boot control instruction data signal, and export boot control instruction data signal to D/A modular converter 15 and output module 16; Boot control instruction data signal is carried out digital-to-analogue conversion by D/A modular converter 15, is converted into voltage spectrum signal and exports dio Output Modules 31 to; Output module 16 exports boot control instruction data signal to solenoid valve driving module 32; Solenoid valve driving module 32 is connected with automobile trunk electromagnetic valve 33, and solenoid valve driving module 32 controls opening and closedown of automobile trunk electromagnetic valve 33, thus realizes the switch control rule of boot.
The course of work of the speech control system of the automobile trunk of the present embodiment is: Audio Input Modules 23 receives the phonetic order from driver, through A/D modular converter 12 data signal that the voltage spectrum signal of Audio Input Modules 23 changes into is input to and compares output module 13, carry out the feature extraction of voice signal, then compare with the sound bank data in sound bank memory module 14 and identify, wherein matching identification algorithm is the speech recognition algorithm based on hidden Markov model; If system identification has gone out the phonetic order of driver, then recognition result is exported to general output module 16, controlled opening and closedown of automobile trunk electromagnetic valve 33 by solenoid valve driving module 32; If system does not identify the phonetic order of driver, then ECU ECU10 utilizes D/A modular converter, converts digitized voice signal to analog signal, exports dio Output Modules 31 to, and prompting driver re-enters voice signal.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken that art those of ordinary skill possesses, various change can also be made under the prerequisite not departing from the utility model aim.
