App uses Avatars to translate speech into Kenyan sign language

A young Kenyan entrepreneur is harnessing AI to break communication barriers for the deaf community. His web app, Terp 360, aims to become Africa’s first sign language translation platform built for local use.

Signvrse’s Terp 360 claims to be Africa’s first AI translation platform built specifically for local use. It translates text and speech into Kenyan Sign Language through avatars, enhancing communication for both deaf and hearing individuals.

“We like to call it Google Translate for sign language—and how this works is it interprets text and speech input and outputs very fluid natural avatars, which is a digital human that now signs the same way a human being does at scale,” explains Elly Savatia, the 24-year-old founder of Signvrse.

Founded in 2023 and a recipient of the Kenya Presidential Innovation Award, Signvrse is on a mission to digitize Kenyan Sign Language by using motion capture systems to accurately record sign language motion from real interpreters. The combination of body movement, hand rotation and articulation, and facial expressions allows the application to accurately capture the linguistic and vibrant nature of sign language.

Eventually, the company hopes the solution can be used in both business and personal contexts through a subscription.

For the deaf community, it could be a very helpful solution to the challenges of daily life. “I had a lot of challenges when searching for a job, and sometimes when I go to hospital, I have a lot of challenges,” says Kelvin Munene, a deaf waiter working in Nairobi.

“I think when using this app, it will help those challenges and it will make communication easier,” he adds.

However, he says he hopes the application can one day use both English and Kiswahili.

Leakey Nyabaro, a member of the deaf community and the founder and director of Galaxy Sign Language Training Centre in Kenya, says, “We find that there are a lot of errors. It’s not that perfect, but somehow I find it more effective when it is sign-to-voice (translation). We find that it is voiced correctly, benefiting more of the hearing community but not the deaf.”

Elly Savatia (interview): “Signvrse is an assistive technology, a social enterprise, with a mission to bridge communication barriers for the deaf community. And, how we do this is? We’ve built Africa’s first AI translation platform called ‘Terp-360.’ We like to call it Google Translate for sign language – and how this works is it interprets text and speech input and outputs very fluid natural avatars, which is a digital human that now signs the same way a human being does at scale.”

Elly Savatia (interview): “Our biggest challenge has been access to sign language data. Looking at the nature of our solution, it heavily relies on localised sign language data to power our platform, and accessing that has been a problem. One, African sign languages are not documented online. You would easily find British Sign Language, American Sign Language data on the web. So we have had to collect our own sign language data, which is expensive. So we really had to push our fundraising efforts to enable us to really generate localised, diverse Kenyan sign language data.”

Elly Savatia (interview): “I think AI is becoming an ongoing conversation and it is an enabler and with companies like Signvrse that are building assistive devices, there is only less that human interpreters are able to do. They are very limited. Context: if I am to take a human interpreter from a legal kind of setting to a medical kind of setting. Now what we are doing is that we are now using AI to have interpretation at a scale and this is the power of AI that we are leveraging on.”

Elly Savatia (interview): “The techniques that we are using to digitise sign language we use motion capture systems to accurately record sign language motion. So we are looking at the body movement, hand rotation and articulation, facial expressions that enables us to accurately capture the linguistic and vibrant nature of sign language as a language and that is what makes our platform unique.”

Leakey Nyabaro (interview): “I have also tried to find out how they transcribe signs, we find that there are a lot of errors. It’s not that perfect but somehow I find it more effective when it is sign to voice (translation). We find that it is voiced correctly, benefitting more of the hearing community but not the deaf. But as well, I think in the nearby future, as it grows into perfection, which it will be, it may reduce the job opportunities for sign language interpreters.”
