What is Chatbot & Virtual Assistant Testing?

Chatbots, conversational AI, virtual assistant services – there’s a lot of different names for one of the most buzzworthy trends in human-machine interaction. These AI services are expanding in the digital realm, taking over tasks that have traditionally been done by humans. Handing these tasks over to artificial intelligence means that more people can be served without having to increase the number of employees serving them.

With the continuous growth of AI-powered language processing and interfaces like Siri, Alexa, and Google Assistant, a vast variety of tools have popped up that bring new approaches for how we interact with digital products and services. For example, you can order a pizza or get flight details from a chatbot, but it still needs to be trained and tested.

Humans interact with the AI through auditory or textual methods and ideally, this should feel like you’re actually interacting with a human being. This provides new opportunities for customer support and service, customer engagement, as well as the overall customer experience.


The Challenge: human interaction is diverse – and so is testing a chatbot conversation

Companies need to ensure that their chatbots and virtual assistants deliver information correctly and quickly, while behaving as naturally and human-like as possible. Due to the diversity and variety present in natural languages, both language training and verification, as well as the correct reproduction of information, are major obstacles to overcome.

The development of natural language processing (NLP), machine learning, and personal chatbot capability is constantly improving. However, the intricacies of local dialects and language itself are still a real challenge – like the surprisingly different respective German dialects spoken in Berlin and Bavaria.

Customers expect to be understood by a language assistant – even if they speak a dialect, have a cold, or have background noise like traffic in their vicinity. Additionally, a virtual assistant bot designed for everyday use should be able to handle input with spelling or grammar errors, just as well as it handles error-free input.

The Solution: Optimize your chatbot’s conversations & behaviour with our large and diverse Crowd

For designing and testing the language capabilities of your chatbot, we have 500,000 experienced testers in our global Crowd. They’re available for both functional tests and usability feedback, in everyday conditions and from your exact target group – including native speakers of specific languages and dialects.

Our intelligent bot and AI tests don’t only reveal weaknesses or faults in the language ability and information processing of artificial intelligence and natural language processing. We’re also able to deliver hundreds of training data sets that can be used to address weaknesses and close language gaps.

After running your tests, our experienced project managers will also give you distinct recommendations on designing your chatbot conversations, and on how to develop and further optimize both personality and capability of your conversation bot.

“Testing a chatbot implicates special requirements that could be met thanks to the use of crowdtesting. Of course, we appreciate the positive feedback from the testers, and their recommendations that are at least as important to us. They allow us to further optimize the app and finally offer our end users a product that has been designed and developed according to their needs.”
