"Talking to a device via voice interface is a very liberating feeling compared to figuring out a vernacular keyboard."
Did you know Sundar Pichai still has panipuri cravings? Students of the Brihanmumbai municipal school in Andheri’s DN Nagar are now privy to that savoury secret after the Google boss’ visit here last week.
And when a student asked Pichai what it takes to be an engineer, the boy next door turned-Silicon Valley pin-up said, “Do you have a radio and TV at home? When it gets old, just learn to break that apart.” It was the perfect photo-op. But Pichai used this opportunity to see how Bolo — a reader app powered by Google AI for text to speech and speech recognition — works on the ground. He even tweeted, “Had the chance to visit some students today who are learning to read using Bolo, excited for all the great books they’ll discover.” Far removed from that suburban Mumbai school, Sid Chatterjee of Austin, Texas, too has a use for voice when he is on the road and has to deal with email. He dictates to his Samsung S8, which has a voice mode in English and other languages, including Bengali. “It’s my default option and has 98% accuracy,” says Chatterjee, chief technology officer of Pune headquartered Persistent Systems, an IT services company. “Talking to a device via voice interface is a very liberating feeling compared to figuring out a vernacular keyboard.”
No doubt, voice is reassuring in the continuous evolution of human-machine interactions, even for hard core techies like Prasad Joshi, vice-president, emerging technologies, Infosys. His mother tongue is Marathi but he has never found it easy to use a Marathi keyboard. “Now, I can talk to my device in Marathi and send voice messages or write mails,” says Joshi, who is also based in the US.
Apart from using voice in their personal lives, both these geeks have seen customer demand for voice-activated products increase significantly in recent months.
Voice is the most natural, intuitive means of interaction. It is basic communication. Yet, it has been almost the last to get there. Using computers and digital devices always meant a familiarity with QWERTY keyboards, basic commands, touchscreens, web interfaces and so on.
Besides, earlier generation voice accuracy left a lot to be desired, and users had no option but to go for keyboards — virtual or physical —always a challenge for older users and others with low literacy levels. As Umesh Sachdev, cofounder, Uniphore, a natural language processing startup, says, “Voice is quicker compared to typing text—150 words spoken compared to 40 words typed per minute.” For those who frequently seek help from random people at post offices and ATMs to fill forms or withdraw money, voice is becoming a game changer.
In terms of projects, “voice counts higher than blockchain or cybersecurity,” says Joshi. Customers are seeking voice activation within apps. In last 12-15 months, voice interfaces are getting better at understanding users, multiple languages and dialects and accuracy. According to Gartner, by 2020, almost one-third of interactions will be through conversations with smart machines.
For the 500 million people already online, voice will be an add on, the most natural way to interact, while for those not yet online due to low literacy or challenge in using keyboards, voice will help leapfrog to that world. Subho Ray, president, Internet and Mobile Association of India (IAMAI), says, “Voice as input will make a big difference for users who are not keyboard savvy.”
Reliance Jio Infocomm is already seeing a preference for voice interfaces among first-time data users. Apart from playing music, helping in search, dimming lights or operating locks, Infosys’ Joshi sees even CXOs use voice commands to fetch market reports or get real time updates from their sales teams.
Banks, too, are experimenting with voice biometrics. Instead of users remembering multiple passwords, their voice could help complete transactions or at least authenticate users when they reach out to customer service. For example, Yes BankNSE -2.12 % has clocked 5.7 million customer interactions via its voice bot. Ritesh Pai, group president and chief digital officer, Yes Bank, says, “Besides serving as a means to input information, voice doubles up as a strong biometricauthentication factor.” For Standard Chartered Bank users, their voice is their password. “It’s a lifesaver,” says Subhasree Basu, a Mumbaibased entrepreneur. “My husband is a digital Luddite and honestly, these days, you need a personal assistant just to remember all your passwords.”
SoftBank-backed PolicyBazaar is working on models where people can say, “Give me car insurance options within this premium,” and get options.
Amazon’s Alexa can order products if you have enough Amazon Pay balance. In January, Alexa started voice bookings from PVR, KFC and Hungama Music. “By 2022, 80% of our interaction with audio visual devices will be non-touch,” predicts Sumit Chauhan, vice-president, lifestyle audio at Harman India, a manufacturer of speakers.
“Voice opens up a new market,” says PN Sudarshan, partner, technology, Deloitte India, a consultancy. For instance, farmers can get prices in local markets by asking their phones and artisans — who might find it challenging to use keyboards — can easily ask devices and learn about exhibitions and markets they can go to.
Alexa claims more than 40,000 developers in India developing voice skills (term for voice apps). Voice assistants are priced at Rs 2,500-18,000 but Sudarshan of Deloitte sees at least a 50% drop in prices in a year, as volumes increase and more brands — including local manufacturers —offer low-cost assistants.
Voice computing will do what Indic language keyboards failed to do. The latter needed some literacy level to use and even people familiar with Indic languages never found them comfortable. Voice command is much faster and easier to input. Daan van Esch, technical program manager, Google, explains, “Indian languages are hard to input in a phone as most have a complicated script. The most natural way for anyone to interact with a device is to talk to it (like with a human). That’s why voice searches are increasing.”
Of course, as with any disruptive technology, there will be concerns, namely security issues (fears that someone can record my voice and transfer money out of my bank account). But for the internet have-nots, the couch potatoes and the people who love chatting, it’s a resounding “yes” for voice input.
