Audi, a well-known luxury car brand, has introduced a brand series of new Q models to the Hong Kong market. Every model within the series has its own unique character, so as our voice. To strengthen the series’ specialness, a Facebook Messenger Bot was created to match participants’ personality with different car models’ distinctiveness by recognizing the speakers’ soundwave. The personality test in chatbot started by user speaking out “Audi”, then a model best fit for the user and its features would be suggested by detecting the user’s volume and pitch. Conversely, the chatbot would reply in a humorous fashion if the user voiced out other brand names. Last but not least, the unique wavelength generated could be saved as a personalized souvenir.
