Internet of Things(IOT) involves connecting physical objects to the internet to provide opportunities to build
smart systems or applications. IOT paradigm assumes many devices connected over conventional intent network. These
devices usually have restricted resources, so moving part of the service implementation to a cloud infrastructure is a
prominent solution. We propose in this project human voice as a potential interface for one or more devices in IOT
ecosystem enabling issuing commands and receiving information. Furthermore the system is enhanced through web
crawling by incorporating trending data. As a proof of concept an automated ticketing system will be implemented.
Concept of a proposed system is designed as an Android application where the user issues commands using voice. Voice
is recorded and immediately sent to STT cloud service using HTTP POST method. As a response it receives JSON object
with multiple alternative transcript of analyzed voice sequence. Transcript alternatives are then matched against set of
supported commands using the Google STT service as automatic speech recognition (ASR) for issuing voice commands.
When the ticketing process is completed the ticket verification process is initiated by the cloud to the IOT board installed
on the Vehicle.
