Fundamental Elements of VUI Design

By Guillaume Privat on November 15, 2018

Voice User Interface (VUI) Design is rapidly emerging as a new discipline in the world of user experience due to the rapid adoption of smart speakers and voice assistants. While a lot has been written about key principles of VUI Design, or how designing for voice radically differs from designing for a screen, not much has been written on the actual concepts that VUI designers can manipulate or should think about when crafting a conversational experience. Visual designers play with layers, filters, gradients, etc...But what can VUI designers play with? What does their toolbox look like?

PullString Converse 2.0: Create Immersive Voice Experiences Powered by Conversational AI

By Guillaume Privat on November 1, 2018

Think about your last great conversation. What made it special? Maybe it was the other person. Or maybe it was the fact that the conversation felt natural and was something you could get lost in? Were you riding the highs and lows of whatever story you were being told, forgetting about everything and everyone else around you? Probably so, and that’s the great part about great conversation. It’s immersive.

The types of conversations you create for a voice application shouldn't be any different. Amazing conversational experiences are not only immersive, they’re also expressive. Through conversational AI, we can now move far beyond basic voice commands and make the shift toward meaningful conversations with voice assistant powered devices.

Modern Conversational Interface Design Misconceptions

By Martin Reddy on August 31, 2018

Conversational user interfaces (or CUIs) are platforms that mimic a natural human conversation, such as the voice assistant platforms Amazon Alexa, Apple Siri, Microsoft Cortana, and Google Assistant. Until recently, computers relied on graphical user interfaces (GUIs) that require additional hardware for visuals and input such as a keyboard or touch pad. Today, CUIs provide an opportunity for the user to communicate with the computer through natural language understanding techniques based on advanced artificial intelligence and machine learning algorithms.

Three Ways Voice Assistants Can Improve Health Care Provider Relationships

By Jenna Cheng on June 26, 2018

"Alexa, can you play some jazz music?"

"Hey Siri, set a countdown timer for 90 minutes."

"Ok Google, remind me to take my blood pressure medicine at 2 PM."

Most owners of a smart speaker or voice assistant device probably haven't progressed much beyond playing their favorite radio stations or turning their lights on and off. And the idea of using a voice assistant to set a specific reminder at a specific time is probably something most of us have not done.

When you see what automation services like can do, and understand how they integrate Amazon Alexa and Google Assistant into their different home automation and smart technologies — HVAC, appliances, entertainment, and security systems including video camera — you realize these voice assistants are capable of so much more.

Move Quickly and Don’t Break Things

By Martin Reddy on July 19, 2017


Think about how hard it is to maintain a text or voice assistant. A service like Siri has to respond to a huge number of different inquiries across an ever-expanding list of domains, such as travel, music, scheduling, reminders, texting, photos, search, sports, entertainment, and more. Apple doesn’t publish a complete list of what Siri can respond to, but it’s not hard to imagine that there are many thousands of possible variations of questions that Siri can answer. Now think about the problem of maintaining all of that carefully-crafted behavior, i.e., manually curating and training all those intents, while also trying to add support for new queries. How can you be sure that any new features won’t break existing behavior?

For example, consider a personal assistant that can understand a user saying “I’m feeling great” and responds appropriately to that statement. Then at some later point, someone extends this bot with the ability for users to specify their name in a format like “I’m Joe Bloggs”. That new feature works as intended so it’s deployed to production. But then you get feedback from your users that if they say “I’m feeling great” the assistant responds erroneously with “Hello! I’ll call you Feeling Great from now on.”.

Even for conversational experiences that are not as deep as Siri, the complexity and inherent ambiguity of the human language means that it can be very easy for changes in intent definitions to have unintended consequences on things your bot could respond to earlier. So how can you, as a bot designer or conversational writer, feel confident that as you evolve and improve your intent models over time they don’t break key workflows that your users expect will work? In the software development world, this problem is addressed using a combination of automated and manual testing, and for any nontrivial system automated testing is critical. Similarly, we believe that having automated tests for your conversational flows is critical for maintaining your bots over time.

The Conversational IDE

By Martin Reddy on February 23, 2017

An Integrated Development Environment for Building Human-Computer Conversations

Software developers are accustomed to integrated development environments (IDEs)—such as Xcode, Eclipse, or Visual Studio—to develop applications. These tools let you navigate entire software projects visually, support convenient editing of code, manage associated media assets, integrate with build systems, and offer built-in debugging capabilities.

There are also specialized IDEs for certain fields, such as Unity, Unreal, or Blender for game and VR development. At PullString, we think a similar capability is equally important for the evolution of the field of conversational AI: to make it easier to create, debug, and maintain the combination of code and content that’s needed to make conversational agents, or chatbots. In other words, we believe the field needs a Conversational IDE.

PullString Now Supports Intents Through, LUIS, and

By Martin Reddy on February 8, 2017

Over the past few years, we’ve seen the emergence of several commercial intent engines. These engines convert arbitrary user input into a high-level abstraction or representation of the user’s intention. For example, a user request like “set the temperature to 70 degrees” may be resolved to an action like “thermostat.setTemperature” with a value of “70” and units “F.”

Hybrid AI and Machine Learning: Letting Computers Talk Back

By Martin Reddy on November 11, 2016

Artificial intelligence is a heavily overloaded term that means different things to different people. As Benedict Evans notes, AI is often used to describe seemingly magical behavior that we don’t yet understand, but once we do we just call it computation. In recent years, the emerging field of machine learning has become very popular and has demonstrated a lot of promise, with some considering it to be a subset of AI and others considering to be a distinct discipline. For more background on the related topics of AI and machine learning, I recommend watching Frank Chen’s fantastic primer.
