Politeness Research in Conversation Design

“Will you have a cup of tea?” – “No, no, no…” – “Go on, you will” – “No really, I’m fine!” – “You will, just a half-cup” – “Oh okay, just a half cup”.

This is a typical conversation you might witness upon entering an Irish home when I was growing up. The three to four turn polite decline, the modification of the offer, the giving in of the half-cup tea drinker. But in some cultures, this up front refusal of the offer may be interpreted as rude or ungrateful.

When designing virtual agents, be they chatbots or voice bots, an awareness of cultural context and social norms around areas such as politeness may make all the difference in a natural, seamless and comfortable user experience. Existing research in fields such as sociolinguistics can inform these design choices. Of course, nuance applies and not all generalizations will hold in every situation, but valuable insights are available to us if we consult the research!

For example, research by Hass & Wächter (2014) found that Japanese and German cultures present two opposite poles of a continuum when it comes to directness/indirectness of speech. A German communicative style favored the former – being more task oriented. The Japanese style favored the latter – valuing group orientation. Research on politeness has also been carried out in the setting of healthcare. Backhaus (2009) presents a cross-cultural comparative study of elderly care home interaction in Japan with elderly care home interactions in a range of different cultural and linguistic contexts. It was found, for instance, that praise, if applied out of context and in too exaggerated a manner, can be interpreted as another expression of the unequal power relations between residents and staff that characterize everyday life in the institution.

Consulting the research on topics like power dynamics and culturally specific values surrounding politeness are a valuable tool in the conversation designers kit.

What is SSML?

You’ve probably heard of HTML but possibly not SSML. Where HTML is used to describe the structure of a web page, SSML (Speech Synthesis Markup Language) is an XML based markup language used in speech synthesis applications. It controls aspects of synthesized speech such as pronunciation, emphasis, pitch and rate. The Alexa Skills Kit supports a subset of SSML tags to make your Alexa skill more personable and customizable. Cool features include things like adding emotions such as “excited” or the addition of audio files to your app. Note – If you’re using the Alexa Skills Kit SDK for Node.js or Java you don’t need to use the <speak> tags!
