Voice bots are AI-powered software that can understand natural language (NLU) and synthesize speech in order to converse with people. Voice bots can run automated call campaigns for various purposes, put data into your CRM and route calls to the appropriate agents.
A virtual agent is an AI-based software program that communicates through voice or text. A virtual agent is also known as an intelligent virtual agent (IVA), virtual rep, or virtual chat agent.
Today, these technologies are widely used by large businesses - banks, airlines, online stores - to communicate with customers. In this article, we’ll look at what has changed since the first assistant appeared eight years ago.
