In this work, we present the recent improvements incorporated in the earlier developed Assamese spoken query (SQ) system for accessing the price of agricultural commodities. The SQ system consists of interactive voice response (IVR) and automatic speech recognition (ASR) modules developed using open source resources. The speech data used for training the ASR system has a high level of background noise...
The signal characteristics of speech collected over microphone depends on the distance between the speaker and sensor, and also on the presence of other background acoustic sources. In the present work, if the microphone is kept close to the speaker, then it is termed as Foreground scenario, otherwise Distant scenario. Even though, presence of other background acoustic sources affect the signal characteristics...
Glottal Opening Instants (GOIs) are those instants at which the glottis opens from the closed phase of glottal activity. Detecting GOIs leads to parameterization of glottal activity regions in terms of open quotient that may be helpful for speaker verification and speech enhancement tasks. Accurately marking such instants directly from speech signal is still a challenging task. Alternatively, Electroglottograph...
In this work, a spoken query system developed for accessing the price of agricultural commodities in Assamese language is described. The developed system enables the user to access the latest price of the commodity by calling the system using a landline/mobile phone. The spoken query system consists of interactive voice response (IVR) and automatic speech recognition (ASR) modules which are developed...
