Automatic Speech Recognition (ASR) is one of the major activities that the centre is carrying out for the last six years. Speech recognition related prototypes (like Bangla digit recognizer, travel enquiry system, automatic phone dialing etc.) have been developed as proof of concepts. C-DAC, Kolkata is now one of the active members of DeitY (Department of Electronics and Information Technology) - ASR consortium. An IVR based real time isolated word speech recognizer on agricultural information domain has been developed as a part of the Phase I project under this consortium.

SPEECH-BASED ACCESS FOR AGRICULTURAL COMMODITY PRICES IN BANGLA
(under DeitY-ASR Consortium Phase I)

Objectives:

To implement and deploy a speech access based system for users to get prices of agricultural commodities over telephone/mobile. Such systems would provide excellent value-addition to the already existing website http://www.agmarknet.nic.in/ managed by the Ministry of Agriculture, since no computer, reading or writing skills are required for the proposed system. The languages covered are Bangla, Assamese, Marathi, Tamil, and Telugu. C-DAC Kolkata is responsible for the system development in Bangla Language.
