How Can Voice AI Help Qualitative Researchers?
Within three years, 50% of Web searches will be done via voice. Today almost one in four US households has access to a smart speaker such as Google Home or Alexa. Consumers are adopting voice technology faster than any other technology, including smart phones. Very soon voice artificial intelligence (AI) will become embedded in our everyday lives to the point where we may not even notice it anymore. How can qualitative researchers leverage this powerful trend?
For inspiration I spoke with four experts who are doing cool things with voice technology. They described unique ways to apply voice Artificial Intelligence (AI) that offer a preview on how this technology might transform our work as researchers. For example, consumers are shifting toward using their voice vs. their fingers to interact with technology and the Internet.
The Rise of the Talking Survey
Greg Hedges has had great success with voice-based surveys through virtual assistants such as Siri, Alexa and Google. According to him, “It’s like launching a focus group of one. People are interacting where they are most comfortable in their own home, using their own words. We’ve found that people are more spontaneous and natural when they talk vs. when they type.” Greg’s company also helps organizations integrate voice branding into their digital marketing ecosystem. Part of their expertise is redesigning a client’s SEO strategy to be phrase and question-based (vs. keyword based) to accommodate voice searches.

Domhnaill Hernon collaborates with artists to explore the deep connections between technology and human potential. He worked with Reeps One, a beatboxer, who fed hours of his audio recordings into Nokia’s AI machine. To their astonishment, the system returned new melodies he didn’t put in but sounded just like him. Rather than feeling threatened, the artist embraced the capability and now incorporates AI-generated tunes into his work. Soon this technology will be widely available, and you’ll be able to produce reports in your own voice that clients can listen to just like a podcast.
It’s hard to imagine how voice technology – and AI in general – will change our world. Technology is always a double-edged sword. On one hand, AI will be used to cure disease, make societies more efficient, and redistribute wealth so humans everywhere prosper. On the other, it might lead to a hardening of the social classes and a surveillance state. In a recent episode of 60 Minutes, AI expert Kai Fu Lee said that 40% of jobs will be eliminated within 15 years due to artificial intelligence. To empower ourselves we need to understand what AI is, how it works, its capabilities and limitations.
How Voice AI Works
As with any artificial intelligence, voice technology relies on two things: having access to a huge pool of data, and algorithms that look for patterns within the data. For voice, the algorithm is called Natural Language Processing (NLP). The result can only be as good as the data that are fed into the machine. Today in North America, Voice Assistants (VA) are 95% accurate if the person speaking is a white native-born man, 80% accurate if it’s a woman, and as low as 50% accurate if the person has an accent. This is because of the socially limited group of people who contribute their data by using voice assistants - VA users tend to be early adopters, white, and highly educated.
Jen Heape notes, “Natural Language Processing (NLP) cannot deal reliably with anyone who is not a white male, and this is deeply problematic, which is why Google and Amazon are giving away so much free so they can collect more complete samples.”
The algorithms that make up NLP leverage fixed rules of language around syntax, grammar, semantics. The algorithm can be taught, “if they say this, say that” and the machine learns the pattern. This capability allows the virtual assistant to process simple prescriptive (but useful) commands such as “turn on the lights,” “play NPR,” or “order more lettuce,” because the technology has learned the vocabulary and structure of English sentences.
Can a Machine Be Conversational?
However, voice technology is still very much in its infancy. The machine has no concept of culture or social inferences. As Heape noted, “If I were to say ‘The kids just got out of school’ and the listener is in the same time zone, they’d know it’s 3 or 3:30. However, the voice technology would not be able to infer this because it lacks the data.”
Freddie Feldman leads a voice design team which creates chatbots and conversational interfaces for medical environments. According to Feldman, chat bots and voice technology in general are helpful in medical environments to get quick answers to predictable questions. “But for anything more crucial, dynamic or that requires understanding the other person’s psychology you’ll need to call someone in the end.” In theory, it’s possible that voice technology will have deeper human characteristics one day. “The technology is there. It’s just a question of someone piecing it together.”
It’s hard to imagine any machine being able to understand and integrate all the rich signals we send and receive in a conversation: the look on a person’s face, the tone of their voice, their diction, their physical posture, our perception of anger and pleasure, or what they are thinking. These elements are as essential to meaning and human connection as the words themselves. As Heape said, “VAs will never replace the human. There will always be a human pulling the lever. We decide what the machine needs to learn. VAs will remove the arduous elements. But we need a human to interpret the results and analyze it. We’re still so much at the beginning of it — we have not fed the machine.”
My feeling is there will be abundant opportunities for qualitative researchers, but – first – we need to understand the beast and what it cannot do.
