【摘要】：由于先天的缺陷，，在大多數(shù)的情況下聾啞人只能被動的接受信息，無法表達(dá)自身主觀的愿望。設(shè)計一種聾啞人語音表達(dá)系統(tǒng)將有助于他們更好的融入到社會生活中。本文綜述了國內(nèi)外聾啞人語音交互技術(shù)發(fā)展的現(xiàn)狀，針對現(xiàn)有的聾啞人輔助發(fā)音系統(tǒng)普遍存在實(shí)現(xiàn)成本高、使用不方便的缺點(diǎn)，提出設(shè)計一種低成本、高可靠性、操作簡便的便攜式聾啞人語音表達(dá)系統(tǒng)。文中詳細(xì)的介紹聾啞人語音表達(dá)系統(tǒng)實(shí)現(xiàn)的兩種方案，并對這兩種方案的可行性進(jìn)行了分析。 基于16位的凌陽單片機(jī)SPCE061A的實(shí)現(xiàn)方案中，綜合考慮成本、功耗、性能的情況下，提出在一個特制的手套上分布有按鍵輸入電路，使用者通過按壓手套上不同的部位實(shí)現(xiàn)系統(tǒng)的輸入，6763個常用漢字和120句日常用語的發(fā)音文件經(jīng)過壓縮處理后存放在一塊SPR4096里�？刂破饕罁�(jù)手部的按壓動作獲取按鍵的操作碼后，程序自動匹配輸入從語音庫中找到對應(yīng)的的音頻文件拼接合成語音然后播放出來。 基于ARM的設(shè)計方案中，考慮到操作簡易、便于移植使用和提高輸出語音的質(zhì)量的情況下，提出使用觸摸屏或三維體感控制器作為系統(tǒng)的輸入設(shè)備，以觸摸屏作為系統(tǒng)的顯示設(shè)備，使用相對成本較低的ARM內(nèi)核的STM32F103微處理器作為系統(tǒng)的控制器，控制器會依據(jù)觸摸屏上輸入的指令從字庫中找到與之對應(yīng)漢字進(jìn)行顯示。同時SD上存儲的與輸入相對應(yīng)的音頻文件將通過SPI接口輸入VS1053音頻解碼芯片進(jìn)行解碼，拼接合成輸出語音。 在詳細(xì)的介紹了兩套聾啞人語音表達(dá)系統(tǒng)樣機(jī)的硬件和軟件設(shè)計后，分別在這兩套系統(tǒng)上進(jìn)行了實(shí)驗(yàn)研究。兩套聾啞人語音表達(dá)系統(tǒng)均實(shí)現(xiàn)了手動輸入句子輸出語音和播放日常用語的功能。實(shí)驗(yàn)效果表明兩套聾啞人語音表達(dá)系統(tǒng)輸出語音的自然度和清晰度都是比較好的。該系統(tǒng)在一定的程度上解決聾啞人與正常人溝通不便的問題，同時為后人進(jìn)行相關(guān)方面的研究提供一定的借鑒，達(dá)到了預(yù)期設(shè)計的要求。
[Abstract]:Due to congenital defects, the deaf and mute can only passively receive information and can not express their subjective wishes. The design of a speech expression system for deaf people will help them to better integrate into social life. This paper summarizes the present situation of the development of speech interaction technology for the deaf and mute at home and abroad, aiming at the disadvantages of high cost and inconvenient use of the existing auxiliary speech system for the deaf and mute, a kind of low cost and high reliability design is put forward. A portable speech expression system for deaf and mute people. In this paper, two schemes of speech expression system for deaf and mute people are introduced in detail, and the feasibility of these two schemes is analyzed. In the implementation scheme of SPCE061A based on 16-bit Sunpositive MCU, a key input circuit is proposed to distribute on a special glove, considering the cost, power consumption and performance. The user realizes the input of the system by pressing different parts of the gloves. The pronunciation files of 6763 common Chinese characters and 120-sentence words are compressed and stored in a SPR4096. After the controller acquires the operation code of the key according to the pressing action of the hand, the program automatically matches the input and finds the corresponding audio file from the speech database to splice the synthetic speech and play it out. In the design scheme based on ARM, considering that the operation is simple, easy to transplant and to improve the quality of the output voice, a touch screen or a three-dimensional body sensation controller is proposed as the input device of the system. The touch screen is used as the display device of the system, and the STM32F103 microprocessor with relatively low cost ARM core is used as the controller of the system. The controller will find the corresponding Chinese characters from the font according to the instructions input on the touch screen for display. At the same time, the audio files stored on the SD corresponding to the input will be decoded by the VS1053 audio decoding chip input through the SPI interface, and the output voice will be spliced together. After introducing the hardware and software design of two sets of speech expression system for deaf and mute in detail, the experiments were carried out on the two systems. Both deaf and mute speech expression systems have realized the function of manual input sentence output speech and play daily language. The experimental results show that the speech naturalness and clarity of the two speech expression systems are good. To a certain extent, the system solves the problem of communication inconvenience between deaf and normal people, and provides some reference for future generations in related research, and meets the requirements of the expected design.
