3. Speech-To-Text (STT) the new PC power tool In computer science and electrical engineering, speech recognition (SR) is the translation of spoken words into text. It is also known as "automatic speech recognition" (ASR), "computer speech recognition", “speaker identification”, or just "speech to text" (STT). Some SR systems use "speaker-independent speech recognition" [1] while others use "training" where an individual speaker reads sections of text into the SR system. These systems analyze the person's specific voice and use it to fine-tune the recognition of that person's speech, resulting in more accurate transcription. Systems that do not use training are called "speaker-independent" systems. Systems that use training are called "speaker-dependent" systems. [1]

9. Text-To-Speech (TTS) A text-to-speech (TTS) system converts normal language text into speech You can use your voice to dictate text to your computer. For example, you can dictate text to fill out online forms; or you can dictate text to a word-processing program, such as WordPad, to type a letter. When you speak into the microphone, Windows Speech Recognition converts your spoken words into text that appears on your screen. 1.Windows Speech Recognition 2.Acapela TTS (Infovox 4)

10. Braille-To-Text (BTT) Braille is a system of reading and writing for blind and deafblind people. It is named after its inventor Louis Braille who developed it from a system called night writing that was developed for communicating with troops after dark, but was not very successful. It uses raised dots, often embossed into heavy paper, to represent the alphanumeric characters and a number of common words. The raised dots are organized into rectangular 6-dot cells, with 64 different configurations

11. Braille-To-Text (BTT) Each letter is represented by a particular arrangement of six dots. Numbers are represented by a numeral symbol followed by the letters A–J to represent the numbers 1–10. Braille Devices 1.Brailler. This is a manual machine rather like a heavy-duty typewriter that embosses the Braille cells onto thick paper to give Braille text. 2.Braille notetaker. 3.Braille displays. 4.Braille embossing printer.
