1. Introduction
Embedded systems play an important role in our day to day life. Due to limited works this systems can be highly optimized by particular needs [27]. Some of the embedded systems applications were controlling the devices with some amount of intelligence built-in [1].
Speech synthesis system has wide range of applications in our daily life. Speech synthesis plays an important role in signal processing. The natural, intelligible synthetic voices in the expanding field of speech technology had a lot of demand [4]. Speech was the natural form of human communication. Automatic speech signal generation on computers is commonly called speech synthesis. Speech synthesis was the artificial production of human speech [2]. Speech synthesizer can be created by concatenating pieces of recorded audio speech that was stored in a database memory. Text-to-speech synthesis was an important object in speech interface, which allows low-bandwidth text to supply a user with easy to gain the information. In speech synthesis field, a number of research programmes have taken place during the last decade [13]. In 1984 an industry expert Mr Drinkwater said that about the synthesis “synthesis is going to be the next bam-burning technology” [2]. Now a day’s synthesis speech was useful for many applications. In 1999 an American business magnate said that “In a few years personal computers will ... talk back to us” [2].
In the past (Allen et al., 1987), the text to speech synthesis was done from a complete knowledge of the acoustics of the language being targeted.
For getting text to speech synthesis different techniques were used [5]. Concatenate method was the simplest method for achieving the synthesis speech. By using this method the speech was generated by linking pre recorded speech segments to build syllables, phrases, or words [2].
The block diagram for the system was shown in the following figure 1.
