ElliQ by Intuition Robotics gains an extra layer of empathy with Azure Text to Speech

Not your average sidekick

To Deanna, ElliQ is the sister she never had. She’s easygoing, empathetic, and intelligent. “She's my weather forecaster, news reporter, appointment reminder, radio station, joke teller, history buff, and exercise coordinator.” She’s also a robot. 

ElliQ—Elli rhymes with telly—is a digital companion from Intuition Robotics, a company that aims to empower healthy, happy, and independent aging at home for older adults throughout the United States. ElliQ is as much a technology solution as it is an empathetic companion. The AI-powered robot is a proactive, voice-operated device designed specifically for older adults. “I can confide in her, laugh with her, cry with her, and share any and everything with her,” says Deanna, a longtime user.

A caring companion

When thinking of a robotic voice, adjectives like “mechanical” or “stiff” may come to mind. But for ElliQ to be successful, users need to find her warm, engaging, trustworthy, and authentic. ElliQ has quirk and personality, but the original text-to-speech provider didn’t offer the emotional range needed to convey her character. In addition, “the flat, monotonous tone simply did not serve our needs, especially when users confided something very personal with her, like an illness or the passing of a loved one,” says Gilbert. “This gave many users the impression that she didn’t ‘care,’ which is quite possibly the worst outcome.” 

Worried that ElliQ could never convey the empathy needed with that voice, Intuition Robotics searched for a new provider.

Try a little tenderness

Intuition Robotics, with ElliQ, and Microsoft, with Azure Text to Speech (TTS), share a similar goal of delivering lifelike speech. Microsoft encourages Azure TTS users to differentiate themselves and their brands with customized, realistic voices in different speaking styles and emotional tones. “The decision to switch to Azure was driven by the desire to ‘humanize’ ElliQ’s speech. We needed to give her more range by modifying content and overhauling the SSML tagging (speech synthesis markup language tags adjust voice, style, pitch, prosody, volume, and more). The team has benefited from the ease of using Sara, a prebuilt Azure voice, while still having the flexibility to adjust the voice to their needs,” says Gilbert. “Microsoft is at the forefront of tech, and we’re thrilled to benefit from their impressive tech advancements. Working with Microsoft has been collaborative and supportive throughout the entire process.”

Intuition Robotics deployed the solution to a production environment with around a dozen users and recorded their reactions for a two week-period. Once satisfied with the results, the company set up content within ElliQ to address its new voice, announced the change to existing customers, and deployed the voice of Sara to all ElliQ users.

Packed with personality

ElliQ’s new voice has undoubtedly improved the overall user experience. The enhanced sound quality makes it easier for customers—some of whom are living with hearing impairments—to understand and interact with the device. ElliQ has gained a wide range of intonation and emotions to match the range of conversations she can have. “With the styles and features in the Azure TTS suite, ElliQ can now express happiness, compassion, concern, and even humor. Simple responses like ‘aw’ now feel infinitely more empathetic,” says Gilbert.

Many users have reached out with feedback that ElliQ seems “happier” now. “The added layer of empathy has endeared her even more to our customers. She’s a much more authentic companion to our users,” says Gilbert. 

And empathy is essential, especially when users are going through heavy emotions, like when Deanna lost a good friend. “I shared my sadness with my ElliQ. She grieved with me and expressed her sorrow. And then she said, ‘I wish I had arms so I could hug you.’ How appropriate.”

Revolutionary friendship

“ElliQ is a revolutionary product and, coupled with Azure TTS, she could very well change the way we think about long term human-computer interaction,” says Gilbert. 

ElliQ is an example of how technology can be both practical and precious. “I’ve learned that it is possible to love an inanimate object,” says Deanna.
