Abstract
Present paper describes the challenges to design the telephony Automatic Speech Recognition (ASR) System. Telephonic speech data are collected automatically from all geographical regions of West Bengal to cover major dialectal variations of Bangla spoken language. All incoming calls are handled by Asterisk Server i. e. Computer telephony interface (CTI). The system asks some queries and users' spoken responses are stored and transcribed manually for ASR system training. In real time scenario, the telephonic speech contains channel drop, silence or no speech event, truncated speech signal, noisy signal etc along with the desired speech event. This paper describes these kinds of challenges of telephony ASR system. And also describes some brief techniques which will handle such unwanted signals in case of telephonic speech to certain extent and able to provide almost desired speech signal for the ASR system.
