The conversational interface team

This step will list and describe the people and skills needed to develop a conversational interface.

What skills and aptitudes are needed to produce a conversational interface? Here are some of those key roles and how they fit into the overall team. Some might be needed for just a part of the project, and others may be involved throughout.

For further information on the skills needed for conversational interface development see the articles linked below.

UX Designer

A user experience (UX) designer considers the path the user takes as they navigate through the application. The UX designer ensures that the experience of the user is as pain free and enjoyable as possible. The UX designer is responsible for understanding user behaviour and designing to optimise the experience. They might consider persona and character development, gender, tone and so on.

Back End Developer

A back end developer is a programmer who is responsible for the behind the scenes code that powers the service or application. This person will create the foundations upon which the rest of the application runs.

Front End Developer

A front end developer is also a programmer, but they are responsible for the part of the application that the user actually sees. This person would be responsible for building the user interface of a text based chatbot for instance. However, for some Interactive Personal Assistants (IPAs) there would be no visual interface so a front-end developer may not be needed here. If an IPA appeared on a hardware device which provided visual feedback to a user in some other way (like lighting up when in “listening” mode), the IPA team would work with the device developers to optimise the effect.

Machine learning / NLP developer

The majority of chatbots and IPAs are powered by sophisticated machine learning and NLP algorithms in the cloud. This gives them the ability to continue improving their service by learning from the data they accumulate. A machine learning and NLP developer will create and implement the actual algorithms used by the interface.

Data Scientist

Just as the conversational interface is powered by machine learning, the machine learning algorithm is powered by data. There is a lot of crossover knowledge between a data scientist and a machine learning developer. The data scientist would be focused more on understanding how data analysis can improve the experience, whereas the machine learning developer will be more interested in practically implementing the algorithms.

Data Engineer

The data engineer will be responsible for making sure the data is “clean” and usable by the data scientist. They are responsible for aggregating data from all the different sources and making sure it is ready to be processed.

Voice actor

In the context of an IPA, a voice actor might be needed to record scripted responses to questions. Although there are people working on synthesising the human voice, there is still room for recorded sound bites of a real human voice.

Script Writer / Linguist

In order for the voice actor to know what to say, or even the synthesised voice, a script writer needs to create believable and effective responses and interactions.


The conversational interface market is still evolving and with the development of new technology that relies on data, there are many questions around data protection and the use of personal data. These issues can get very complicated and a lawyer with good knowledge of data legislation would be a useful member of the team.
