摘要:人們生活中的絕大部分信息都是通過視覺獲得的,所以盲人能夠從外界獲取的信息量很少,但這并不能阻止他們努力提高生活質量的渴望。智能手機的快速發展給盲人提供了前所未有的機遇。開發盲人手機具有極大的應用價值。該文主要介紹了在Android平臺上設計和實現的一款盲人手機系統,該系統使用了語音識別、語音合成及Web Service等相關技術,實現了語音撥打電話、語音接聽電話、語音發送短信、語音播報來電短信、語音報時、語音播報日期和語音播報天氣等功能,并能在Android手機中穩定運行,方便盲人使用手機,具有較高的實用價值。

Abstract: Most of the information in people's lives is obtained through visual, so the blind can rarely get information from the outside, but that cant stop them from efforts to improve the quality of life. The rapid development of the smartphones provides blind people with an unprecedented opportunity. And developing mobile phones for the blind has great practical value. This paper introduces the design and implementation of mobile phone system for the blind based on Android, which uses the technologies of speech recognition, speech synthesis and Web Service, and it has achieved making and receiving calls by voice command, sending and receiving text messages by voice command, telling time, date and weather by voice command and so on, which can run steadily on the Android platform to help the blind use mobile phones, which has high practical value.
Key words: Android; mobile phones for the blind; speech synthesis; speech recognition
教育心理學研究表明:人們生活中獲取的外界信息大約83%來自視覺,11%來自聽覺,這就導致了盲人能夠從外界獲取的信息量很少。如何幫助盲人利用聽覺、觸覺等其他感官來更多地獲取外界信息,更好地融入社會生活,享受科技進步帶來的便利?智能手機快速的發展為這一問題找到了解決途徑。它豐富的傳感器、強大的網絡功能和計算能力、不斷擴展的連接能力,以及云計算的廣泛使用,使殘疾人可望更準確、實時地感知周邊環境,使用適合自身的方式來表達自己,在更大范圍內參與工作和生活,充分實現自己的人生價值。面向盲人開發的智能手機(盲人手機),具有極大的應用價值。
在Android移動平臺上,開發了一款盲人手機系統,該系統以語音合成及語音識別為基礎,使盲人能夠通過聲音控制系統功能的執行,并通過觸控語音提示反饋信息,以此來實現手機與盲人的交互。……
