  2. 2. Speech Recognition in web Apr. 23 What is Speech recognition? In Computer Science, Speech recognition is the translation of spoken words into text. It is also known as "automatic speech recognition", "ASR", "computer speech recognition", "speech to text", or just "STT". Speech Recognition is technology that can translate spoken words into text. Some SR systems 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. 2
  3. 3. Speech Recognition in web Apr. 23 Speech recognition in Web Speech recognition in web is achieved by implementing Speech Recognizing system using powerful languages which have ability of interacting with operating system (such as Java, .NET, pearl). Flash and Java Applet is used as front-end which takes user’s input in the form of voice compare it with grammar base present in the system and returns the result. Speech recognition in web is consisting of following elements. 1. An engine with various Grammar models or Back-End 2. Front-End which is of Java Applet or Flash 3. Scripting languages API for web programmers Approaches: 1. HTML5 approach (webkit based approach which currently limited to Google chrome browser and working fine and recognize dictionary based words correctly) 2. Using Flash, Java Applet and Javascript as front-end and conventional languages at back-end (available APIs are speechAPI, WAMI, iSpeech) except iSpeech (which is premium API) other two are experimental API and not working fine. Usage: 1. Voice web search 2. Speech based games. 3. Speech based web catalog Conclusion: So, currently the best approach would be using Google chrome’s webkit based API which gives optimum results as other APIs are in experimental state.
