HUL – KKT & Speech recognition


Kan Khajura Teshan is Hindustan Unilever (HUL) award winning marketing campaign to engage with bottom of pyramid market. Kan Khajura Teshan (KKT) is a mobile radio playing 18 minutes of entertainment content in Hindi. The content has jokes and bollywood songs, which is moderated by a radio jockey. The content is refreshed every Monday of the week. KKT Mobile radio has its reach even in media dark areas where there is no FM radio or television. KKT has 30 million subscribers and is getting a million unique visitors logging on, on a daily basis.

Ozonetel provided the technical solution required to run the campaign, the main component of the marketing platform is cloud communication platform and speech recognition system. Here I would elaborate how the HUL leveraged speech recognition and speech analytics.

KKT is using real time gender recognition system, Speech based IVR, Digit recognition and Keyword spotting.


Real time gender recognition:
After playing the entertainment content HUL plays its advertisement, for running a successful advertisement it’s very important to know the gender of person listening the ad. Before playing the content few questions are asked from customers, with the help of Real time gender recognition KKT determines the gender and accordingly plays the ads based on customer gender. Ozonetel gender recognition is used to identify gender of 30 million person with a success rate of 99%.

Speech Based IVR flow:
Today most of IVR uses touch tone or DTMF(Dual tone multifrequecy) based user interface, in KKT to make the IVR more efficient and responsive they used voice based IVR user interface that allows customer to use their own voice than DTMF inputs to complete the interaction. Voice based IVR flow made the campaign user friendly. Our Speech based IVR flow response rate is 20 ms and it can handled multilevel of IVR.

Digit recognition system -
The digit recognition system is the core of voice IVR flow, ozonetel’s digital recognition system is independent of language, it can successfully recognize digits in 17 language.

Keyword spotting and data filtering-
The amount data generated from this campaign was huge, HUL want to reuse the data for customer analytics and in other marketing campaign. Keyword spotting is used to segregate the data- Ex- HUL want to segregate the customers who shown interest in “love” song or spoke “love” at least once, by using keyword spotting, data could easily be segragated the accuracy of Ozonetel’ s keyword spotting is 95%
