使用LabVIEW实现语音播报系统设计 摘 要 近年来，多媒体技术得到迅速发展，多媒体系统的应用更以极强的渗透力进入人类生活的各个领域虚拟仪器基于计算机的自动化测试仪器系统通过软件将计算机硬件资源与仪器硬件有机的融合为一体，从而把计算机强大的计算处理能力和仪器硬件的测量，控制能力结合在一起，大大缩小了仪器硬件的成本和体积，并通过软件实现对数据的显示、存储以及分析处理。LabVIEW是NI推出的虚拟仪器开发平台软件，它能够以其直观简便的编程方式、众多的的设备驱动程序、多种多样的分析和表达功能支持，为用户快捷地构筑自己在实际生产中所需要的仪器系统创造了基础条件。NI公司的LabVIEW软件为开发平台，通过安装Microsoft中英文语音引擎SDK包，设计播报系统界面和调节按钮，然后配置声音属性，选择声音样式、语速、音量大小等，最后通过调用语音引擎完成文本到语音的朗读。 关键词：LabVIEW，文本朗读，SAPI The Design of Voice Broadcast Systems Using LabVIEW Abstract In recent years, with the rapid development of multimedia technology, multimedia system applications but also to strong penetration into all areas of human life, including TTS technology as the frontier of information processing technology, its unique advantages in the audio output to occupy an important position. Virtual instruments are computer-based automated test equipment system. It organic the hardware resources and equipment for the integrated by hardware, to together the powerful computer processing and the hardware control of the measuring instruments, greatly reducing cost and size of hardware devices and achieve display, storage and analysis and processing for data. NI LabVIEW is the introduction of virtual instrument software development platform, it can with its intuitive and easy programming, a large number of the device driver, a wide variety of analysis and features expression of support for users to quickly and easily build the instrument system their own needs in production to create basic conditions. The design use NIs LabVIEW software as development platform, by installing the Microsoft Speech Engine SDK package in English and Chinese, design the regulation buttons and interface of broadcast system, and then configure the sound properties, select the sound style, speed, volume, size, and finally by calling the Voice complete text to speech engine to read. Key words: LabVIEW, text to speech, SAPI 目 录 摘要 I Abstract II 1 引言 1 1.1 课题背景和意义 1 1.2 本课题研究内容与主要工作 1 1.3 本课题的研究预期成果 2 2 总体系统概
