3. INTRODUCTION TO .NET
 .NET is a framework developed by Microsoft
 New programming methodology
 .NET is platform independent/cross platform
 .NET is language insensitive
 It includes a large class library known as Framework Class
Library(FCL)
 Microsoft also produces an integrated development
environment largely for .NET software called Visual Studio
 It provides language interoperability (each language can use
code written in other languages) across several programming
languages

9. C# Language
◦ C# is intended to be a simple, modern, general-purpose, object-oriented
programming language.
◦ Its development team is led by Anders Hejlsberg.
◦ The most recent version is C# 5.0,released on August 15, 2012.
◦ Developed specifically for .NET
◦ Enable programmers to migrate from C/C++ and Java easily
◦ Event-driven, fully OO, visual programming language
◦ Process of rapidly creating an application using an IDE is called
Rapid Application Development (RAD)
◦ Language Interoperability and Reusability
◦ Windows Desktop, Windows Phone and Web Application &
Services

10. TEXT TO SPEECH CONVERTER
 It is the window application based on speech synthesis
technology
 It converts written text into spoken language
 The first general English text-to-speech system was
developed by Noriko Umeda in 1968 at the
Electrotechnical Laboratory, Japan
 There are many TTS conversion applications in market
such as Text2Speak, CoolSpeech, Verbose,
eSpeak,TextAloud etc
 The procedure consist of two main phases:-
 A)Text Analysis
 B) Speech waveforms

11. A) TEXT ANALYSIS :-
The input text is transcribed into a phonetic or some other
linguistic representation
B) SPEECH WAVEFORMS:-
The acoustic output is produced from the phonetic and prosodic
information

12. STEPS FOR TTS CONVERTER

13. ARCHITECTURE

14. TTS technology used in :
 Apple : The first speech system integrated into an OS that shipped
in quantity was Apple computer ‘s MAC intalk. The Apple Ios used
on the iPhone, iPad and iPod Touch uses VoiceOver speech
synthesis for accessibility.
 Android: Version 1.6 of android added support for TTS.
 Microsoft windows: Coolspeech, Textaloud and ultrahal can
perform various text-to-speech tasks such as reading text aloud
 Internet: Currently, there are a number of applications, plugins and
gadgets that can read messages directly from an e-mail client and
web pages from a web browser or Google Toolbar such as Text-to-voice
which is an add-on to Firefox

15. TTS technology used in:
 Multiple companies offer TTS APIs to their customers to accelerate
development of new applications
Companies offering TTS APIs include
 AT&T
 IVONA
 Neospeech
 Readspeaker
• For mobile app development:-
 Android OS has been offering TTS APIs for a long time
 Most recently, with iOS7,Apple started offering an API for text to
speech

16. OTHER FEATURES :
 Media player :-
 It is a simple media player which plays all audio and
video format files
 Speaking Dictionary:-
 Get meanings of the words present in the database
 Tap your entry to hear the pronunciation
 It also show synonyms and antonyms of the words

17. APPLICATIONS
 Talking Calculator
 Computer generated wiring instruction
 Aids for the blind
 Telephone inquiry service
 Teaching machines
 Usage in education and daily life

18. ADVANTAGES
 Able to read large paragraphs
 It offers a range of different accents and voices
 Provide significant help for people with eyes disabilities
 It can be adapted easily to say whatever users want them
to say
 Interacting application when user’s eyes and hands are
busy

19. LIMITATIONS
 No explicit emotions
 Homographs(Pronunciation)
 Prosody
 Language specific problems
 Special Characters and symbols

20. FUTURE SCOPE
 Accuracy will become better and better
 This application is also used in smart phones
 Increasing variety of voices
 This technology can also work in different languages like
Kannada,Gujrati,Marathi etc.
