Abstract

This thesis describes how to prepare and design a voice-controlled assistant(voicebot), which can be deployed on any website as a modern way to communicate with customers using internet browsers. The main emphasis is put on synchronization between voice dialog and the graphical interface of the website. The synchronization can be achieved by transferring bidirectional voice and text commands between client and server. This is achieved by using WebRTC technology with SIP as a signaling protocol. The thesis deals with a wide range of protocols and technologies as well as interconnecting VoIP telephony, computer networks, and Phonexia speech technologies based on machine learning. As a result, deployment of the voicebot can reduce costs on outgoing calls, ease agents of a FAQ burden, and increase customers' interest in the product/company.
