Speech input-output system in Indian farming sector

In this research paper, we have developed a Speech input-output System in Indian language that can be useful in bridging the gap between lab and land. This voice enabled system will be very helpful to Indian farmers to retrieve the cultivation information like availability of seeds, fertilizers, pesticides and methods of farming. The speech input-output system is very beneficial in two angles for Indian cultivation domain, first it needs the input query of farmers in voice mode which completely avoids the end users to be literate persons and secondly the response of the system also in voice mode which is more comprehensive for every class of end-user. Speech input-output system was developed using CMU Sphinx4 for understanding the enduser query and speech synthesis was achieved by playing the prerecorded sound files for providing the response to the spoken query. We have collected the speech corpus related to Indian cultivation for this research work in Odia language which is one Indian official language. The performance evaluation of the system is measured in terms of percentage of word accuracy and word error rate as well as using mean opinion score (MOS) test. The word accuracy for known and new users is found to be 86.87% and 75.13% respectively. The MOS test for speech output is found as 4.62 on an average.
