How to use text-to-speech on TikTok


TikTok's text-to-speech feature allows creators to put text over their videos and have a Siri-like voice read it out loud. It's a helpful way to annotate your videos to help describe what's happening, add context, or to serve whatever purpose you see fit. There's also no rule saying you can't use it just to make the text-to-speech voice say silly things. Here's how you can easily add text-to-speech to your TikTok videos. You can cancel it, edit the text, or adjust the duration of the text just by tapping the text again. Once you're happy with your video, just click "Next," apply whatever hashtags you want, and post!

Finally, text-to-speech that doesn't suck


We're a couple of decades into the 21st century, cars are literally starting to fly, a vacation to space is just around the corner ... and yet somehow, computers still sound like parodies of confused robots whenever asked to convert text-to-speech (TTS). Come on, devs, there has to be a better solution. A firm called WellSaid Labs believes it has one, and it's getting a boost thanks to an oversubscribed Series A. "Plain and simple, WellSaid is the future of content creation for voice. This is why thousands of customers love using the product daily with off-the-charts bottom-up adoption. Matt and Michael have assembled a world-class team, and we couldn't be more thrilled to be a part of the WellSaid journey," says Cameron Borumand, General Partner at FUSE, which led the round.

Backpack exoskeleton makes walking easier by taking the strain off knee muscles

Daily Mail - Science & tech

Walking upright is one of the things that makes us human, but it's not the most efficient form of transport. Now researchers in Canada have developed a lightweight exoskeleton that reduces the amount of energy needed to walk. The device, the bulk of which is housed in a backpack, could allow a person to walk farther without tiring. The exoskeleton also absorbs the kinetic energy of the wearer as they walk and could soon generate enough electrical power to charge a smartphone or other small devices. Researchers at Queen's University in Kingston, Ontario have developed a lightweight exoskeleton that reduces the amount of energy needed to walk by 3.3 percent For bipeds like humans, the sequence from when one foot contacts the ground to when that same foot touches down again is called'a gait cycle.'

Exoskeleton takes strain off legs to reduce energy needed for walking

New Scientist

An electrical generator built into a backpack can make walking more efficient by taking the strain off leg muscles, while also harvesting a small amount of electrical power. The device reduces the energy required to walk by more than 3 per cent and could also charge small electrical devices. Many exoskeletons have been designed to make humans stronger or more efficient. Some have a power source and actively assist limb movement. But Michael Shepertycky at Queen's University in Kingston, Canada, and his colleagues have now created an entirely passive system that reduces the effort required to walk.

Removing energy with an exoskeleton reduces the metabolic cost of walking


Many devices have been developed to harvest energy from walking or running, but their use often comes at cost to the wearer in the form of increased metabolic demand. Shepertycky et al. designed a device that can harvest mechanical energy from a natural walking gait and convert it to useable electrical energy while also reducing the metabolic energy consumption of the user (see the Perspective by Riemer et al. ). The key to achieving “something from nothing” comes from designing the device to use muscle-centric control of the knee exoskeleton resistance to reduce active muscle force during the late part of the leg swing cycle. Science , aba9947, this issue p. [957][1]; see also abh4007, p. [909][2] Evolutionary pressures have led humans to walk in a highly efficient manner that conserves energy, making it difficult for exoskeletons to reduce the metabolic cost of walking. Despite the challenge, some exoskeletons have managed to lessen the metabolic expenditure of walking, either by adding or storing and returning energy. We show that the use of an exoskeleton that strategically removes kinetic energy during the swing period of the gait cycle reduces the metabolic cost of walking by 2.5 ± 0.8% for healthy male users while converting the removed energy into 0.25 ± 0.02 watts of electrical power. By comparing two loading profiles, we demonstrate that the timing and magnitude of energy removal are vital for successful metabolic cost reduction.

Text to Speech System for Multi-Speaker Setting


What would you want to do if you could generate the voice of your favorite celebrity? Before I get ahead of myself, let me clearly define the objective of this blog. Given text and some voice clips of the desired speaker (say, Beyonce), I want my AI to output an audio clip where Beyonce is speaking the text that I input to this code. So essentially, this is the same Text To Speech (TTS) problem we saw earlier but with an added constraint to output the speech in a particular speaker's voice. In this blog, I share two methods that can complete our task, and I will be comparing these two methods at the end.

A Sense Of Touch Boosts Speed, Accuracy Of Mind-Controlled Robotic Arm

NPR Technology

President Barack Obama bumped fists with Nathan Copeland during a tour of innovation projects at the White House Frontiers Conference at the University of Pittsburgh in 2016. President Barack Obama bumped fists with Nathan Copeland during a tour of innovation projects at the White House Frontiers Conference at the University of Pittsburgh in 2016. A robotic arm with a sense of touch has allowed a man who is paralyzed to quickly perform tasks like pouring water from one cup into another. The robotic arm provides tactile feedback directly to the man's brain as he uses his thoughts to control the device, a team reports Thursday in the journal Science. Previous versions of the arm required the participant, Nathan Copeland, to guide the arm using vision alone.

'I exist': How one TikToker is trying to normalize limb difference -- and bionic arms

Washington Post - Technology News

Olive's videos are part of a trend on TikTok where creators living with disabilities will tell their stories or explain how they perform certain tasks, using hashtags such as #disabled and #amputee. They stand in stark opposition to Hollywood, where people living with disabilities is one of the most underrepresented groups. Its 56.7 million members constitute nearly 20 percent of the population, according to the 2010 Census -- and a study from the University of Southern California Annenberg Inclusion Initiative that focused on 900 popular movies from 2007 to 2016 found that only 2.7 percent of speaking characters were portrayed as disabled.

Text To Speech Explained from basic


As the title suggests, in this blog we are going to learn about text to speech (TTS) synthesis. What is the first bell which rings in your mind when you listen to text to speech? For me, it's Alexa, Google Home, Siri, and many other conversational bots that are on an exponential rise currently. Advances in deep learning research have helped us to generate human-like voices, so let's see how we can use that. I'll start with a few definitions, but if you want to understand these more then read this blog first.
