The first broad-spectrum speech feature library has first broad-spectrum speech feature information corresponding to the first speech feature information, and the second broad-spectrum speech feature library has second broad-spectrum speech feature information corresponding to the second speech feature information.

The first and second speech feature information may include spectral distribution information of the speech command, time domain waveform information, short-time spectrum of the speech frame, formant frequency and bandwidth, nasal sound joint feature, spectrum correlation feature, pitch feature, power spectrum, frame energy, speech intensity and variation trajectory feature, or may be a combination using one or more of the above feature information.

Wherein, furthermore, the preferable mode of the navigation service can be also as follows: when a user selects a value-added service of the system as a navigation service, the user sends a voice command (such as 'i want to navigate'), a non-specific voice recognition module analyzes the voice command for starting the navigation service (such as 'i want to navigate'), extracts corresponding first voice characteristic information (such as spectrum distribution information of the voice command 'i want to navigate'), searches a broad-spectrum voice characteristic library set according to a starting command keyword according to the extracted first voice characteristic information, and acquires a navigation service starting command (such as 'i want to navigate') corresponding to the first voice characteristic information from the broad-spectrum voice characteristic library set according to the starting command keyword, so that the corresponding navigation service is further started according to the recognized (namely acquired) voice command (such as 'i want to navigate'); after the navigation service is started, the unspecified person voice recognition module analyzes a voice indication command (such as 'dragon building') of a target navigation address, extracts second voice characteristic information (such as spectrum distribution information) corresponding to the voice indication command (such as 'dragon building'), searches a broad-spectrum voice characteristic library set according to a place name according to the second voice characteristic information, acquires the place name (such as 'dragon building') corresponding to the second voice characteristic information from the broad-spectrum voice characteristic library set according to the place name, and acquires the navigation address (such as the address of the 'dragon building') corresponding to the place name according to the recognized place name.

For another example: when the value-added service is video-audio on-demand service, the unspecified person voice recognition module analyzes a voice command for starting the video-audio on-demand service, extracts corresponding first voice characteristic information (such as frequency spectrum distribution information and the like), searches a broad-spectrum voice characteristic library set according to a starting command keyword according to the first voice characteristic information, and acquires a navigation service starting command corresponding to the first voice characteristic information; the unspecific person voice recognition module analyzes the voice instruction command containing the target video and audio description information, extracts corresponding second voice feature information (such as frequency spectrum distribution information) and searches a broad spectrum voice feature library set according to the video and audio description information according to the second voice feature information, and video and audio description information corresponding to the second voice feature information is obtained from the broad spectrum voice feature library.

It should be noted that the broad-spectrum speech feature library provided in this embodiment is a set of broad-spectrum speech features extracted by collecting sounds of places, various people and the people in the whole china under different environments (different noise backgrounds), and the broad-spectrum speech feature library only depends on information of the existing "speech feature library" and does not depend on a speech feature training result of a certain person. The advantages are that: (1) the selected sample of the broad spectrum speech feature library is extensive and includes human utterances from different regions of different countries of the world. For example, in China, the pronunciation of people in almost every province, county, town and region in China is selected, people in different regions in the country are divided into several categories, such as the North China, the northeast China, the Minnan language region, the Guangdong language region and the like, the Mandarin spoken by people in different regions has local dialects with different characteristics, and after the people are classified respectively, the people in the regions with basically similar local dialects pronunciations are classified into one category, so that the completeness of a sample is considered, and the construction of a database is also considered to generate redundant information as little as possible; (2) extracting voice characteristic information of sounds or voice commands under different environments (noise backgrounds), such as voice commands generated after an automobile engine is started, voice commands generated under the conditions of wind dryness and fetal noises generated after an automobile window is opened, voice commands generated under the conditions of interference such as sudden plug-in of other people and the like, voice commands generated after the engine is closed and the like; (3) the broad-spectrum speech feature library comprises a Mandarin feature library and a local dialect feature library, wherein the local dialect library comprises a Minnan language library, a Guangdong language library, a Shanghai language library and the like.

At least one of the above-mentioned situations, such as situations of people in different regions or situations in different environments, has been considered in the first and/or second voice feature information, i.e., the first and/or second voice feature information is voice feature information extracted based on voice or voice commands of people in different regions, or the first and/or second voice feature information is voice feature information extracted based on voice or voice commands of people in different environments. This improves the recognition rate of voice commands to users or drivers in different regions.

Further, the broad-spectrum speech feature library also comprises a foreign language library, wherein the foreign language library comprises mainstream foreign language libraries such as an English library, a French library, a German library and a Japanese library. The system also has a feature library automatic recognition module which is used for analyzing the voice command sent by the user to distinguish the feature library corresponding to the voice command and automatically selecting the corresponding feature library. Therefore, the user can use the languages of different countries to send out voice commands in a mixed mode, the languages can be used in a mixed mode without being screened in advance, and the automatic recognition module of the library feature library can automatically recognize whether the voice commands are Chinese or foreign languages.

The broad-spectrum voice feature library established by the method is arranged in the cloud computing platform server, so that the dependence on a system of terminal equipment is reduced, the terminal equipment in front of a speaker is used as sound or voice command acquisition equipment, and the acquired sound or voice command data is transmitted to a background server group such as the cloud computing platform server for identification, so that high-performance identification calculation under a multi-server cluster architecture can be performed, and the large-scale voice feature library can be used without the voice identification capability of the terminal equipment.

In this embodiment, 95% of the voice information may be recognized by the unspecified person voice recognition module, in order to ensure that 100% of the voice information of the user can be recognized, and further improve the user experience of the vehicle-mounted service, optionally, as shown in fig. 1, the cloudcomputing platform server 104 may further include an unspecified person voice recognition manual agent module, where the unspecified person voice recognition manual agent module is configured to, when the unspecified person voice recognition module cannot recognize the voice command for starting the value-added service, and obtain a corresponding value-added service command, and/or, when the unspecified person voice recognition module cannot recognize the value-added service voice instruction command, and obtain the instruction information related to the value-added service.

and 209, the terminal equipment starts the corresponding value-added service according to the value-added service control information, establishes connection with a server providing the value-added service through the vehicle-mounted communication equipment, and acquires the value-added service from the server, wherein the vehicle-mounted communication equipment establishes connection with the server providing the value-added service in a target network access mode.

In order to further ensure reliable connection between the terminal device and the cloud computing platform server on the network side and the server providing the value added service, the vehicle-mounted communication method provided by the embodiment of the invention may further include: the vehicle-mounted communication device periodically detects the signal intensity of the target network access mode, if the signal intensity of the target network access mode is smaller than a preset signal intensity threshold value, a new target network access mode is selected again, and connection is established between the new target network access mode and the cloud computing platform server and the server providing the value added service.
