No screen, no problem: Low-cost audio computers deliver lifesaving info in Ghana

Computers without screens may seem archaic and nearly useless to consumers in more privileged parts of the world, but in Ghana’s poorest communities they’re relied upon as the delivery channels for lifesaving education. Talking Books, as these screen-less audio computers are called, will serve as crucial mobile devices for 40,000 people in Ghana as part of a large-scale endeavor spearheaded by Literacy Bridge, UNICEF and ARM Unite.

The Talking Books are equipped with micro SD cards that hold up to hundreds of hours of audio that educate illiterate listeners in about 50 poor, remote villages in Ghana about Ebola and cholera prevention and treatment, breast-feeding during the first six months of a child’s life, identifying and treating diseased crops, and creating and applying organic fertilizer made from livestock’s manure, among other critical topics.

Each device speaks to its listener in their local language and dialect. It also gives listeners the option of pressing buttons to indicate their interests. “The message might be a song, a story, a drama, an interview with a public health officer or a peer in your own community,” said Cliff Schmidt, executive director of Literacy Bridge, in an interview with the BBC.

Schmidt adds that each Talking Book comes with a microphone so listeners can respond to what they hear. “They can provide useful feedback like, ‘I just didn’t understand what you meant here’ or ‘You mentioned this problem, but let me tell you about another problem that is even more important for our community.’”

Listeners can also adjust the speed of the audio and be prompted by “audio links” to hear definitions of words they don’t know or answer multiple-choice questions in interactive quizzes.

Talking Books, built to endure dust storms and tropical rain, contain cheap zinc-carbon batteries available in Ghana’s local markets, which offer up to 15 hours of power. However, researchers at the University of Michigan are working on a new design using a custom chip, which will allow for longer use. Literacy Bridge aims to make the Talking Book available in other African countries.

Will the future of the Talking Books, originally built in 2007, include screens? Ken Banks, an adviser to the UK’s Department for International Development, certainly thinks it should. “Rather than just assuming that illiterate people will likely always be illiterate, why not integrate something into this device which will actually help them develop skills, rather than just passively listening and never having the chance to learn to read?” he told the BBC. Banks points to older Kindles as examples of what the future of Talking Books should look like.

These 3 gadgets prove wearable tech reached its peak in 2024

What a great year for wearables 2024 has been. Don’t believe me? We’ve had three standout products this year. One has individually broken new ground, an established product line has been refined so it’s close to perfect, and another has driven other brands to muscle in on its success.

Let's talk about each one in turn, why they all complement each other really well, and how there has never been a better time for wearables.

I finally have RCS on my iPhone, and it’s one of my favorite iOS 18 features
An iPhone 16 Pro showing RCS messaging.

Apple’s Messages app has certainly come a long way. When the first iPhone launched in 2007, it could only send SMS -- there weren't even picture messages. Then it got MMS protocol support in iPhone OS 3.0 with the iPhone 3GS. With iPhone OS 5.0, Apple implemented its own iMessage chat protocol, making it easy for Apple users to communicate with other Apple device users.

However, when it came to messaging Android users, Apple dragged its feet for the longest time, sticking with SMS and MMS, which aren’t encrypted and don't offer full-quality photo and video sending. It also sparked the whole blue bubble versus green bubble war.

The 2025 Android phone I’m most looking forward to isn’t from Samsung or Google

2025 is rapidly approaching, and that can only mean one thing for a tech nerd like me: It's time to start looking forward to another year of smartphones. All signs are pointing to an interesting year for Apple with the iPhone 17, and I'm eager to see what comes of it.

But what about what's happening in the Android smartphone space? The Samsung Galaxy S25 series is just on the horizon, but I've yet to see anything that's made me really ecstatic about it. The Google Pixel 10 series should be a good one, but we've not heard enough about it yet.
