::SPEECH PROCESSING::

Speech Recognition:
Speech recognition is the process of converting a speech sound to a sequence of words, by means of an algorithm implemented as a computer program. We are currently working on Bangla speech recognition using Hidden Markov Model (HMM) as the technique and HTK as the toolkit. The performance of Isolated and Continuous Speech Recognition is tested for Limited vocabulary list using the HTK toolkit. Currently we are concentrating on the preprocessing issues and also looking for other tools for speech recognition.

::DOCUMENT AUTHORING::

We need a smart yet efficient editor for document authoring. At the same time, we need a way for Bangla language input without having to master all the available keyboard layouts. This is where BanglaPad and Pata come in.

TTF to Unicode Font Converter:
There are number of Ascii based Bangla fonts out there. The trouble with these fonts is that if the host machine doesn’t have the font installed, then the text gets jumbled up. We are working on a TTF to Unicode Font converter which will enable us to convert the Ascii encoded text to a Unicode enabled text. That way, we just need to have a Unicode Bangla font installed and we will be able to see the text properly.

BanglaPad:
BanglaPad is an open-source, platform-independent text-editor. It has support for Rich-text editing and exporting to html format. The text-pad is capable of Bangla Spell-checking and intelli-sense i.e. it can suggest words in case of spelling mistakes.

Pata: Pata is a Bangla Transliteration tool. Type phonetically in English and you will get similar sounding dictionary word in Bangla. Now you don’t have to memorize all the different keyboard layouts. You can enter Bangla text without actually typing in Bangla.
