文本到语音的最新发展已经切换到级联合成，要么使用原始语音段，要么使用参数合成。以前的TTS系统提供了更好的质量输出，因为它们使用原始的语音段进行拼接。语音生成技术有PSOLA、TDPSOLA、EMBROLA等。本文描述了在Android平台上基于Epoch同步不重叠和添加(ESNOLA)技术的马拉雅拉姆语拼接系统的开发和实现。TTS使用类似双音素的片段(部分)作为连接的基本单位。该数据库包含1500个部件，用于生成无限领域文本的语音。本文还简要介绍了马拉雅拉姆文TTS的实现、数据库的生成、对Android平台的修改、Android平台下对数据库的访问和对马拉雅兰文字符显示的处理，以及TTS应用程序对正确渲染显示字符的支持。该应用程序支持安卓最新版本至安卓4.2。本文还讨论了基于Android的应用程序新闻阅读器的设计。TTS在知觉测试中的平均意见分数(MOS)为3.2。
The recent development in text to speech has been switched to concatenative synthesis, either using original speech segments or parametric synthesis. The former TTS system gives a better quality output since they use the original speech segment for concatenation. There are a number of different other techniques for speech generation like PSOLA, TDPSOLA, EMBROLA etc. This paper describes the development and implementation of concatenative based system based on Epoch Synchronous Non Overlap and Add (ESNOLA) technique for Malayalam in android platform. The TTS uses diphone like segments (partneme) as the basic units for concatenation. The database contain 1500 partnemes, which are used for generating speech for unlimited domain text. The paper also briefs about the implementation of Malayalam TTS, the database generation, the modification done for android platform, the database access and handling Malayalam character display in android platform, the support provided in the TTS app for displaying characters with proper rendering. The app support android latest versions upto android 4.2. The design for Newsreader, an application using android is also discussed in this paper. The TTS gives a Mean Opinion Score (MOS) of 3.2 in the perceptual test..
