Communication is a human right - but what happens when someone can’t speak for themselves?

Sean Allsop struggled to talk until he was eight years old, when he began to speak thanks to years of speech therapy. He explores the technologies and innovations helping people around the world who struggle to communicate.

We meet Richard Cave, National Advisor at the Royal College of Speech and Language Therapists, as he introduces a patient and their family to voice banking, a method that preserves someone's voice before it's lost, using recordings to create a personalised synthetic version. He explains why having your own voice is a major part of your identity.

In the United States, we hear from people trialling a brain chip that turns neural signals into speech. It's still in its early stages, but how close are we to seeing this kind of technology more widely available for those who would benefit from it? A child-friendly robot made in Luxembourg is teaching children with communication difficulties how to express emotions and build social skills. And in San Cesareo, Italy, the simplest solutions can sometimes prove the most effective. The town has introduced AAC (Augmentative and Alternative Communication) sign boards in public spaces, helping both users and non-users learn and connect.

What if reimagining how cities are designed could make women safer? In Cairo, sexual harassment and violence against women on the streets has been endemic. Women don't feel safe enough to walk or take public transport. A pioneering programme called Safer Cities, is hoping to find the solution through radical urban redesigns, women friendly spaces and raising awareness about sexual harassment. Salma El-Wardany, who was born in Cairo, visits a women’s only park in Imbaba, Giza and meets Samaha who runs the park. She not only oversees the children playing, but also organises events for local women with advice and support. Salma visits Zenein Market in Giza, which was redesigned to better support the majority of female sellers there. They show Salma the older part of the market which is yet to be regenerated. Salma also speaks to Caroline Nassif, who worked as Project Officer at UN Women, as well as local NGOs, and Minister Manal Awad Mikhail who was one of the driving forces behind the scheme across locations.

From powering cars to feeding farm animals, how using seaweed more can help the planet. We hear how a local business in Barbados is using sargassum seaweed to power cars, providing an eco-friendly alternative for islanders and potentially helping to clear the beaches of smelly seaweed. Also we visit the European company aiming to replace single-use plastics with seaweed-based packaging. And how feeding seaweed to cattle can dramatically cut emissions of planet-warming methane gas.

Citizenship is a kind of social contract that exists in democracies. To function effectively, members of society need to feel like they can engage with and improve their communities. We take a look at two projects helping people do just that in Portugal. We explore a scheme that has helped 30,000 teenagers team up with politicians to transform their local areas. And we hear how another project has enlisted older people in society to train as agents in disaster prevention and spread their knowledge in the wider community.

In 2017, Spanish engineer Pablo Bergasa began an unusual hobby: to design a new incubator for use in African hospitals. Eight years on, he has sent 200 of his machines around the world, and he estimates they have saved the lives of 5,000 babies. Pablo’s incubator costs a small proportion of the price of a regular machine and can run on a battery and a bottle of water. Plus Myra Anubi hears about how a simple but ingenious plastic sheet is saving women from dying after giving birth.

Food waste is one of the biggest environmental and economic challenges we face — and much of it happens long before the food reaches our plates. In this episode, we meet the people working to tackle the problem in different ways. We hear about the smart sensors which could help cut down waste by measuring when food has actually gone bad rather than relying on one-size-fits-all expiry dates. And in Scotland Myra visits the start-up turning waste from whisky production into fish food.

Despite a lot of progress in the last few decades, more than a billion people still live in acute poverty, according to the UN. Many don’t have access to basic needs like food, water, shelter and clothing. We look at an innovative project in Paraguay where people identify their own needs using a traffic light system and are then linked up with businesses, NGOs and government bodies who they work with to improve their lives.

How the numbers of stray dogs - and feral pigeons - can be kept down kindly in urban areas. From street dogs to feral pigeons, many towns and cities are having to deal with exploding bird and animal populations which can pose risks to health and safety. This week we take a look at ways we can control numbers in an effective and humane way. We visit a special pigeon loft in Germany, where pigeon eggs are swapped with dummy eggs to help manage the population. And we take a walk with tourists in Mexico, who are helping to socialise stray dogs while also providing funds for their care.

Being in hospital can be frightening and lonely for children — but playful ideas are helping make the experience a little easier. In Scotland, professionally trained clowns are visiting paediatric wards to bring joy and distraction, while in the US, immersive video games are helping young patients come to terms with illness and long stays. We meet the people using creative ways to brighten up a stay in hospital for children and teenagers.

Barcelona in Spain is famous for its beautiful streets, lined with tall apartment buildings. But the architecture is a problem for many people who have lived for years in upstairs apartments but who now find the stairs unmanageable.

In 2008, a survey found that in one district there were 300 people who could not leave their homes alone. A group of volunteers decided to do something about this and got hold of a special wheelchair with caterpillar tracks, so it can be used to take people up and down stairs. After an initial pilot scheme they launched a local service called “Let's Go Down to the Street”, to help elderly residents go shopping or meet up with friends. Sixteen years on, the service is offered across the city.

Plus we visit a home for senior citizens in an unlikely location: a university campus. The Mirabella complex at Arizona State University in the US offers its residents the chance to sample the college lifestyle – from lectures to shows and sports fixtures.
