Embodiment 1

[0023] as attached figure 1 Shown, its structure of a kind of car navigation voice recognition rate automatic test system of the present invention is specifically made of operating module, processing module, horn driving part and loudspeaker, and operating module is connected with two-way communication of processing module, and processing module, loudspeaker driving part and loudspeaker successively connect. The speaker sends a sound signal to the car navigation, and the car navigation obtains the result of voice recognition after its own judgment. The result is transmitted to the processing module through the transmission of the communication line. The processing module obtains the test result through information comparison, and feeds back the result to the operation module to display.

[0024] After the test is completed, the test data can be exported through the data output interface involved in the processing module.

Embodiment 2

[0026] as attached figure 1 As mentioned above, when the test starts, after the tester inputs the corresponding entry on the operation module, the operation module sends the input entry to the processing module for processing, and the processing module, on the one hand, processes the input information after receiving the entry information Save, on the other hand, send the entry information entered this time to the speaker driver, and the speaker driver will amplify the sent information after receiving the entry information and perform audio processing on the audio processing chip, and generate this information through the speaker. Input the pronunciation of the entry for the first time, and the sound will be transmitted through the speaker. At this time, the car navigation can receive the sound information and recognize the received guided information. At the same time, because the car is running, the GPS in the car navigation will Record the route traveled in the process of r...

Embodiment 3

[0029] The difference with Embodiment 2 is that when the audio processing module performs signal processing, it can be processed into a male voice or a female voice, and the size of the signal can be adjusted, that is, the pitch and volume of the sound output by the speaker can be controlled.

Abstract

The invention provides an automobile navigation speech recognition rate automatic test system. The automobile navigation speech recognition rate automatic test system comprises an operation module and a speech recognition rate automatic test tool; the operation module is connected with the speech recognition rate automatic test tool; the speech recognition rate automatic testing tool is connected with an automobile navigator; the operation module is used for external command input, transmitting commands to a processing module, and displaying information fed-back by a processor; and the speech recognition rate automatic test tool is used for processing signals from the operation module so as to emit sound and collecting signals fed-back by the automobile navigator. With the automobile navigation speech recognition rate automatic test system adopted, manual labor in a speech test process can be greatly decreased, test quality can be improved, influence on measurement results caused by manual pronunciation factors can be prevented, the measurement results can be collected and put into statistics conveniently, speech test efficiency and quality can be greatly improved, and test costs can be significantly reduced.

Description

technical field [0001] The invention relates to the field of speech recognition rate testing, in particular to an automatic test tool for car navigation speech recognition rate. Background technique [0002] At present, speech recognition technology has entered various fields such as industry, home appliances, communications, automotive electronics, medical care, home services, consumer electronics, etc., such as car navigation, the increase of speech recognition functions has greatly improved driving safety, but the speech recognition rate There is no systematic test method for the test. [0003] At present, the test methods of speech recognition rate basically adopt manual testing, especially in the test of car navigation, the testers read the entries word by word, and the same entry needs to be carried out at different speeds of the car. Read, because the sound of the engine has different effects on speech at different speeds, it needs to be measured separately, which gr...
