Thirdly: implement and test an initial version. Can they be defined as a series of specific actions that need to be performed in order? Secondly, analyse the processes you will pass onto the bot. What problem do you need it to solve? How will you measure its success? What metrics will you use? In order to develop a voicebot, you first need to define its functionality. In fact, we’ve already written a comprehensive guide to voicebot implementation ( part 2) – so in the interest of not repeating ourselves too much, here’s the Cliff’s Notes. By now it’s possible for essentially any company to roll their own voicebot using a platform such as SentiOne (cough, cough). While these sound like complicated technologies, they are becoming increasingly accessible. We already touched upon the key elements of a voicebot: speech recognition, natural language processing, speech synthesis. We also have application-specific voicebots: they route calls, provide technical support or perform various services specific to the company running them. We have virtual assistants, like Siri and Alexa, that can handle a wide selection of tasks: checking the weather, sending text messages, playing music. That’s how we ended up with a wide variety of voicebots. Adding voice processing functionality on top of that was a logical progression. Suddenly, text-based chatbots running as a service could handle tens of thousands of users simultaneously (you can read more about chatbots in our guide to chatbots!). This rapidly changed in the 2000s, as PCs became more and more powerful. ![]() ![]() While useful, this was about as much as computers of the era could handle. These programs were used for dictation and could handle tens of thousands of words. If we define them as “computer programs that do things based on human speech”, then the first commercial applications for the technology came in the late 1980s and early 1990s. Through very basic language analysis, it could simulate a psychotherapy session – and it *almost* seemed humanlike!Ĭombine these three ingredients in a magic cauldron (or a whole bunch of technical universities), let them cook for a couple of decades, and presto – voicebots. In 1966, ELIZA was released – this program is often considered the very first chatbot. This, too, has been in the works for the better part of the twentieth century. This is the machine learning technique through which computers can derive meaning from words and sentences. The third piece of the voicebot puzzle is natural language processing. It couldn’t do much more than that, but if you really tried, you could dial a telephone number with Audrey. In 1952, Bell Labs demonstrated the “ Audrey” system, an enormous beast of vacuum tube circuitry that was capable of recognising digits from human speech. In fact, computers could recognise human speech back then, too – with severe limitations, but still. By the time HAL 9000 captivated movie audiences in 1968, computers were singing songs for nearly a decade. ![]() In fact, voice synthesis, a fundamental part of voicebot design, was being worked on long before electronic computers were invented. What Kubrick and Clarke demonstrated in 2001: A Space Odyssey wasn’t as far removed from reality as people usually like to think. “I’m afraid I can’t let you do that, Dave.” For decades, talking to your computer was primarily a staple of science fiction and not a practical reality. There’s even a term for it: “conversational user interface”. Ready? What is a voicebot?Ī voicebot is a computer program operated through conversation. We’ll take you behind the curtain and show you what exactly makes voicebots tick and why they are so sought after in today’s business world. It is, in part, thanks to this newfound popularity that we are publishing this article. They are an invaluable tool in customer service, for instance! As an example, a voicebot we implemented for the Polish financial company KRUK helped reduce their call centre volume by 23%! ![]() While they don’t get as much attention as our daily companions, there is a wide variety of voicebots in a lot of different businesses. The mass adoption of voice assistants such as Siri and Alexa paved the way for voicebot technology to be used in a wide variety of specific applications. This might sound rather self-aggrandizing, coming from a voicebot company, but it’s true – and we have the data to back it up. ![]()
