Most of us are used to saying, ‘Okay Google’ or ‘Alexa’ or ‘Hey Siri’, followed by an instruction to get the weather or call a contact and so on. Interactive conversational AI is now big business, spanning people’s homes as well as customer support at the world’s biggest companies.

Deep learning algorithms are becoming increasingly human in the way they interact with humans, through voice or chat messages. Yellow.ai in Bengaluru is a startup that wants to take this further—automating all ‘customer experience’ interactions.

A discussion about poor customer support gave birth to Yellow Messenger, the startup that CEO Raghu Ravinutala co-founded with two friends. They started with an Android app for people to interact via messaging with businesses. Today Yellow.ai has customers around the world.

“The vision of our company is total customer experience automation,” Ravinutala says. Yellow.ai has more than 700 large customers in more than 50 countries. The company is backed by well known venture capital investors, including Lightspeed Venture Partners.

At the heart of Yellow.ai’s technology is its ability to make sense of natural language, whether on chat or voice. It has built a natural language processing (NLP) engine to handle interactions between companies and consumers. This is trained to understand how people talk or chat and then trigger actions to resolve the customer’s queries. Yellow.ai supports multiple languages around the world.

Automating these workflows is another area where the company is using AI. A third area is conversational analytics. With billions of conversations between companies and their consumers, there is the opportunity to derive useful information on customer segments. For example, a beverages company figured out that South Indians like spicy cocktails while North Indians prefer sweeter ones, Ravinutala says.

When Yellow.ai started, the use of conversational AI was not widespread, Ravinutala says. Since then advances in speech-to-text and vice versa, and identification of sentiment from voice have helped companies like Yellow.ai build their applications on top of core technologies that became available.

An important driver of the use of AI is to make technology more human, Ravinutala says. In voice, for example, there are efforts to fine-tune the tonality and audio quality of the AI assistant to resemble a human. One could even have a virtual customer support agent provide support with the voice of a film star, he says.

The technology is moving towards incorporating human-like empathy in the modulation of the voice produced by the AI engine.
