Application of voice technology in vehicle equipment
The development of in-vehicle electronics began with traditional radio functions, and then continued to introduce new technologies along the lines of CD, VCD/DVD/mobile TV, GPS/EOBD, car phone, mobile office, and opened up a wider range of The more intelligent and user-friendly in-vehicle applications. This paper introduces the application of voice technology in in-vehicle equipment. This technology can play the text information in the car in the form of voice, so that the driver will not distract from watching this information, thus improving the safety of driving. This article refers to the address: http:// Voice technology has a wide range of applications in in-vehicle devices. Taking reading as an example, with the advent of the Internet age and the increasing popularity of office automation, more and more information is in the form of words, but it is restricted by the vehicle environment, and the text information is read by eyes, both for drivers and passengers. There is great inconvenience. At this time, using the voice synthesis technology to transform the traditional car audio, the car audio can not only listen to the radio and music, but also listen to the various text information selected by the user. In addition to providing CD, tape songs and radio functions, car audio in the future can download various types of text information such as novels, Word documents, and emails to the car to listen to, and allow users to select various information they like. A truly humanized car stereo that will be read aloud. Voice car phone The car phone provides a convenient way for drivers to communicate while driving. From a security point of view, it is very inconvenient to look at information while driving, such as the appearance of electric numbers, time, short messages, and so on. Using embedded speech synthesis technology, it can realize that the car phone information becomes a listener, greatly enhances the way of information acquisition, lowers the danger of driving, and adds more humanized functions to the mobile phone. figure 1 The system implementation is shown in Figure 1. The voice car phone adds an embedded voice synthesis chip to the original car phone to realize the playback of the information content. The car phone obtains various types of information through the GSM/CDMA network, such as caller information, short messages, etc.; the mobile phone control module converts various types of information that need to be synthesized, such as caller information, short message, address book information, and notebook information, into standard The text information is sent to the embedded speech synthesis chip; the embedded speech synthesis chip converts the text information into speech and plays it to the user through the in-car audio system. To implement voice synthesis on a car phone, you can choose an embedded voice chip or voice module. The size of the car phone itself is small, and the power consumption is not large. It is more suitable to select the voice chip. Although the voice chip has a worse effect on any text synthesis than the voice module, it can fully meet the practical requirements. In addition, through the customized digital small system, "incoming call notification" and the like can also achieve a good synthesis effect. The S3111 speech synthesis chip used in the voice car phone, its working principle is shown as in Fig. 2. figure 2 The S3111 voice chip exchanges data with the car phone main control chip through the RS-232 asynchronous serial port, and converts the information on the mobile phone main control chip into voice information and broadcasts it to the user through the speaker. The voice car phone is changed to listen and improve the driving safety factor. Its features include: 1. Caller number broadcast. The incoming call information received by the mobile phone, including the order of the call, the caller, the caller's number, and the call time, are automatically broadcasted with clear and smooth voice, and the mobile phone user can immediately know the caller information and decide whether to answer the call; 2. Time and schedule reminders. At any time, you only need to press the button to broadcast the current time, and broadcast the scheduled task during the schedule reminder; 3. Information broadcast. With the embedded speech synthesis software, the various received text messages can be broadcasted out to solve the problem that the mobile phone screen is small and difficult to read, and it is convenient for people to obtain information. Voice car GPS At present, GPS technology has been widely used in the automotive field. With the increasing number of urban vehicles and the increasing traffic pressure, it has become increasingly important to make it easier and quick for drivers to obtain information, to change to listen and to reduce driving danger. GPS information can also be converted to sound and embedded to the driver through embedded speech synthesis technology. The vehicle can realize its own positioning through the vehicle GPS, and then send its own position and status (such as speed, orientation, etc.) information to the information center through the GPS communication module function; similarly, the information center can also send Chinese short information (such as navigation information) to the vehicle. , weather forecast, various customized information, etc.). GPS enhances the car's anti-theft performance and assisted driving function (navigation information), but the driver's access to information is often in the process of driving, while browsing information while driving is very unsafe, there are traffic hazards, using voice technology can solve this problem well. problem. image 3 The schematic diagram of the system implementation is shown in Figure 3. The system consists of a GPS analysis module, a control module, a signal processing module, and an embedded speech synthesis module. The working process is as follows: the vehicle GPS obtains various types of information through a GPS information providing network (such as GPRS/CDMA), such as navigation information, road condition information, weather forecast or personal information customized by the user through the information center; the control module will need to synthesize each The type information is downloaded from the GPS parsing module to the signal processing module; the signal processing module converts the information content into standard text information and sends it to the embedded speech synthesis module; the embedded speech synthesis module converts the text information into speech through the in-car audio system Play to the user. Voice car GPS needs to synthesize more texts, and it is more casual, not easy to customize, and each user needs to customize the service content is different, so the effect of speech synthesis is higher. In addition, the size of the car GPS itself is large, it is easy to find the space embedded in the voice module. From the functional point of view, the user hopes to realize the voice communication function with the information center through GPS, which needs to solve the problem of voice codec, and the embedded voice synthesis module supports the voice codec function. Considering comprehensively, it is recommended to use embedded speech synthesis module in voice car GPS. Figure 4 The car GPS can use the S3231 speech synthesis module, and its working principle is shown in Figure 4. The S3231 voice module interacts with the vehicle GPS master chip through the RS-232 asynchronous serial port to implement TTS service and voice codec service. In the TTS service, S3231 converts the received text into sound, and then directly outputs the voice through the audio output channel; in the voice decoding service, the S3231 will receive the encoded data (user customized information, the information center is in the form of voice encoded data) Down to the car GPS) decoded into voice data, and then output through the audio output channel; and in the voice encoding service, S3231 will encode the received audio data (user input through the microphone), and then transmit the voice data through serial communication Give the GPS master chip. The voice car GPS function can play navigation information, let the driver know the best walking route, and also can play the road condition information, let the driver prepare in advance, as well as traffic jam, emergency handling and so on. In addition, the weather forecast and customized information can be played. The local information center knows that the local weather forecast and the customized content service are told to the driver when the vehicle arrives at the local area. The customized information content mode of the user can be voice compressed data.
