Present paper describes the overall architecture, design and evaluation process of an Interactive Voice Response based Commodity Price Retrieval System for semiliterate or illiterate farmers. Here users just need to dial a 24x7 helpline number to get market wise latest price information on recognition of district and commodity names in Bangla language. Telephonic speech data has been collected automatically from all geographical regions of West Bengal to cover major dialectal variations. Sustained efforts have been given in real-time speech data collection, transcription, system design, evaluation and field trial analysis. Additionally to meet users' expectations in field conditions, distinctive error recovery methods like Signal Analysis and Decision, Confidence Measure and Polling, Complementary Information, Runtime model generation etc. are incorporated to confirm performance enhancement in final trial. This system is providing excellent value-addition to the already existing AGMARKNET website managed by ministry of agriculture, India; as no computers, internet, or even reading/writing skills are required for this application.
