The Disadvantages Of Synthetic Text-To-Speech In Advertising

24 December 2020

Speech to text conversion is commonly used in advertising as an alternative to using a real human voice. It works using technology that converts input text into speech that is designed to be as natural as possible.

There are a lot of variants on the type of technology used, but overall the software tends to be very similar and fairly easy to get hold of for businesses who want to use it in their advertising.

If you are considering using this modern software for your next advertising campaign, it’s definitely worth thinking carefully about. Despite it being somewhat cheaper than real human voiceovers, there are some pretty chunky downsides to be aware of.

Let’s take a closer look at the disadvantages of synthetic text-to-speech in advertising:

It Is Unlikely To Be Quicker Than A Professional Human Voiceover

Many people think that a computer system will be a quicker way to get a voiceover when in fact the system used can be very time consuming and challenging to use correctly. It isn’t a simple process and there’s quite a lot of learning involved in order to get a good result.

The Results Are Never As Natural As A Human Voice

Despite the incredible advances in technology with AI voices, the result of text-to-speech technology is still pretty robot-like. The natural nuances of the human voice have still not been mastered when it comes to AI voice so if you do plan to use AI vocals for your advertising campaign it is important to know that it will be noticeable.

People Don’t Like AI Voices

73% of people don’t trust AI voice technology and 71% of people prefer a human voice rather than a synthetic one. When it comes to your branding and message, that’s quite a big factor. Could an AI voiceover turn your audience off your advertising?

Pronunciation Will Not Be Perfect

If you’re wanting a clear message from your AI voiceover you may struggle with text-to-speech. Pronunciation is always a little bit off, which means your messaging may well be lost somewhat via the voiceover.

Technology Is Still Young

You may feel that soon enough there will be a way to use AI in text-to-speech advertising that is cheaper and quicker than a real voiceover. The problem is that great AI voice-overs are pretty far off. Technology has advanced a lot but nowhere near making it easier, quicker, and realistic compared to a human voice-over actor. Using text-to-speech advertising now means accepting its limitations.

Pace Of Speech Is Unnatural

The speech will be read as it is written when you use text-to-speech software. This means that there won’t be any natural pauses, hesitations, and silences as you would have with a professional voiceover actor. Companies offering text-to-speech software will advise you to add exaggerated pauses and paragraph breaks in your script to get around this issue. The fact is that this doesn’t sound dramatic or effective, it just sounds awkward because the AI voice can’t add the tone and intonation necessary to make those pauses make sense.

Consider Using A Professional Voiceover Service

If you want a natural, personality-filled, professional voiceover for your advertising, consider using a professional voice over agency. The costs compared to text-to-speech are surprisingly affordable, and the results are second-to-none compared to AI voices. It could be the perfect way to give your advertising the professional finish you’ve been looking for.

How Well Does Carbon Fiber Perform in the Cold?

Carbon fiber is a composite material prized for its durability, lightweight, and high heat resistance. While these may be the most impressive qualities of carbon fiber for some, only some people \need these features in the products they develop. Those interested in developing innovative products often require a specific set of advantages when searching for the perfect building material for their designs. A manufacturer might sometimes require a high resistance to cold rather than heat. Choosing an alternative composite material that is resistant to extreme cold is a possibility. Still, this solution will not suffice if that material does not offer the other benefits that carbon fiber can provide. Considering the Many Facets of a Composite Material That’s why it is critical that the most well-known qualities of any composite material do not outshine every other quality they offer. Instead, it is valuable for manufacturers to understand the multi-faceted advantages that composite materials like carbon fiber have to offer to stay at the cutting edge of innovative product design. The Impact of Cold Resistance on Vehicles One of the most common uses of carbon fiber is in vehicle development. Since this particular composite material is strong yet lightweight, it can allow manufacturers to construct vehicles with less resistance to move faster without sacrificing the stability of a strong frame. This fact does not solely apply to ground vehicles like cars and military craft; carbon fiber is used in aircraft, marine craft, and spacecraft for the same advantages. Carbon Fiber Parts Rather than construct an entire vehicle or its frame out of composite materials, designers often employ carbon fiber parts to replace existing parts on a vehicle. This allows the designers to add some of the benefits of carbon fiber, such as weight reduction, without requiring an entirely new design. How Carbon Fiber Response to Extreme Temperatures While there is a lot of discussion about the heat resistance of carbon fiber as a benefit in vehicle production, it is less commonly known for its use in freezing temperatures. Nonetheless, carbon fiber is frequently employed in sports gear used in cold conditions, such as skis, ski poles, and cycling. There is further evidence for the capabilities of carbon fiber in the extreme cold since it is used in spacecraft such as satellites and re-entry vehicles. In such situations, temperatures can range from extremely hot to near absolute zero. Matrix and Reinforcement When considering the performance of carbon fiber under intense temperature conditions, it is critical to consider how composite materials are made. Since carbon fiber materials are composed of a matrix and a reinforcement material, the temperature resistance may vary depending on the material used as a matrix. In the case of carbon fiber composites, the carbon fibers make up the reinforcement materials, while the matrix may be Polymers Metals Ceramics If you’re interested in using carbon finer in an application that involves exposure to extremely cold temperatures, talk to a composite material manufacturer about the best option in a matrix for your needs.

Waterjet Vs. Laser Cutting: Which Is Worth The Hype?

Waterjet and laser cutters can slice through materials that no other cutting tool can. They are invaluable for prototyping products and precision manufacturing. But which one is worth the hype - waterjets or laser cutters? This article provides everything you need to know about waterjet vs laser cutting units. Learn how they work and which one is best for your industrial manufacturing facility. Waterjet Vs Laser Cutting: Unlike the vast majority of blades and saws, waterjets and laser cutters don't have a blade. The lack of a blade makes engraving and detail work much more precise. And, waterjets and laser cutters are computer operated, as to achieve a very high level of precision. Both machines can engrave minute lettering and symbology into a wide range of manufacturing materials. But each machine goes about it a very different way. Both methods of cutting excel with 2D objects and engraving, but which is better: waterjet or laser cutting? What Is Laser Cutting? Laser cutting uses a high-focus laser to cut or engrave materials. Laser cutting is a method of subtractive manufacturing, which means it only takes away material. This is in opposition to additive manufacturing, like 3D printing. Special software guides the lasers using mirrors. A gas power source provides energy to the system, usually in the form of CO2. The CO2 fuels the laser which outputs between 1,500 and 2,600 watts. Some systems implement an additional gas jet to expel the excess material. Laser cutting is a very precise form of subtractive manufacturing. The intense heat of the laser cuts through material like a razor using a precision burn. Laser systems cut material from sheets or large panels. Laser Cutter Materials: Laser cutting systems make precision cuts in a wide range of materials. The only material that a laser cutter is not "cut-out" for is reflective metals. The reflective property of some metal reflects the laser off of the cutting surface, which can be dangerous. Laser cutters are great for cutting glass, wood, plastic, and a wide range of metals. Laser cutters encounter obstacles, however, when trying to cut compound materials. If the material contains multiple materials, then it has multiple melting points. If the material has multiple melting points, then a laser takes longer to cut through it, and cuts can become uneven. Laser cutting systems work the best with flat sheets of material, with a thickness range between 0.1 inches to just under a half-inch. And, most laser cutting systems proficiently perform the functions of cutting, drilling, engraving, welding, ablating, and structuring. What Is Waterjet Cutting? Waterjet cutting systems utilize a high-pressure waterjet to slice through materials. The water is shot through a very fine point and creates over 60,000 pounds of pressure per square inch. For tougher materials, a mixture of water and an abrasive acts like a diamond saw blade. Garnet is a common abrasive for use in waterjet cutters. Aluminum oxide is another common abrasive that you can use with a waterjet cutter. The process of waterjet cutting is a high-speed version of natural erosion. With a big enough waterjet cutter, you can make another grand canyon in a fraction of the time. Read more about how the best water jets can cut through anything nature makes. Waterjet cutters differ from laser cutters in that the power source does not reside with the cutting unit. Since a waterjet cutter outputs between 4 to 7 kilowatts, the water pump is located away from the worksite. This is also true because the water source is rarely nearby your bench. Waterjet Cutting Materials: Unlike a laser cutter, waterjet cutters can effectively cut almost any material. They have no problem cutting through compound materials with multiple material types. The pure pressure of the water jet is enough to cut cleanly through anything. Waterjet cutter units are especially useful for cutting precisely through masonry. They're also good for cutting and structuring stone, thick metals, ceramics, and glass. Waterjets handle thicker material than laser cutters. They can handle material that is up to around 2 inches thick. But they don't do as well with material thinner than 0.4 inches. Level of Waste from Waterjet vs Laser Cutting: Laser cutters create a minimal amount of off-fall and waste. Very little, if any, cleanup is required after cutting. The only waste that laser cutting produces is a small amount of dust that is easily vacuumed up. Waterjet cutting, on the other hand, creates a lot of waste. You might think that waterjet cutting would be cleaner, but it is not. The abrasive material in the water adds a toxic element to the off-fall liquid. For this reason, waterjet cutting requires special waste-water disposal, safety gear, and a bigger project budget. What's the Cost to Purchase and Operate a Waterjet vs Laser Cutter? A plasma laser cutting machine will cost between $15,000 to over $250,000 at the initial purchase. Waterjet cutters are more expensive because they require more specialized materials. They range from $100,000 to around $400,000. On average, either machine will cost around $350k. Expensive industrial machines can exceed $1,000,000. On average, a laser cutter costs between $13 to $20 an hour to operate. Waterjet cutting systems run between $15 to $30 an hour to operate. Final Thoughts: At the end of the day, waterjet cutters cost up to five times more to operate than laser cutters. Waterjet cutters can cut thicker and more complex materials, but they are slower than laser cutters. So, when considering waterjet vs laser cutting, laser cutting will save you time and money.

5 Reasons Students Need Technology In The Classroom

Modern technologies have started to challenge the traditional forms of education. In fact, it seems that informal or experimental tech-infused learning processes are becoming more and more popular these days. Why would it be so? Well, technologies clearly carry lots of study benefits for students and teachers. After all, the tech world is here to make our lives easier and better. Digitalization of education can provide schools with newer teaching techniques, more learning options, and program enhancement. However, you can see it for yourself. Here Are Five Reasons Why Students Need Technology In The Classroom: 1. Personalized learning We have long discovered that each individual has preferred study methods and learning needs. However, most teachers can’t deliver a personalized lesson to each student. School programs operate on standard programs and materials. Such an approach can’t meet every student’s needs. It also can’t help in discovering and revealing everyone’s potential. Technology, however, can fully adjust lessons for adaptive learning. Thus, classroom digitalization can help teachers recognize every student’s learning style and adjust lessons accordingly. Such a change in the study program will increase lessons’ efficiency and students’ productivity. As of now, each individual is busy with tasks aimed directly at their needs. Moreover, such tactics will also increase autonomy in classrooms. Thus, teachers can trust the tech-designed programs and give students space to learn individually. 2. Remote learning options Of course, it’s important to acknowledge what a game-changer cloud technologies have become for education. This tech novelty has become the foundation of remote learning. Now, we can receive information at any place and at any moment. Of course, we all know that the Internet has long become the main depository of all kinds of information. People often use their gadgets to learn new things ‘on the go.’ These days students know where to seek information or help online. In fact, there are even pages like Behind the scenes of reviewing essay writing services that help young people make the right choices in their pursuit of assistance. Of course, none of it would have been possible without technology. However, cloud technologies are also great for schools that practice remote learning. Thus, educators can now share their study materials, homework assignments, and even lectures online for their students to learn. Such an option is surely rather new for the education system. Yet, recent events in the world have taught us to appreciate the possibility of remote learning. 3. Learning enhancement Modern technologies have many ways to enhance the learning process in a classroom. Thus, tech-infused studying can have multimedia involved. So, students can learn new information through various media like videos. Such learning methods can increase students’ attention and retention. Media helps students keep their focus longer. It makes learning more engaging. So, people are more likely to stay interested for the lesson duration. In fact, students may even receive larger chunks of information. Yet, they can perceive them easier. In addition, various media can work for different learning methods. Thus, students get to receive information in various formats. Such learning can enhance lessons’ messages and expand one’s knowledge. Such tactics can replace the repetitive approach common to traditional learning. 4. Assistance in teaching On average, the modern tech world tends to scare away older generations of educators. They either fear making mistakes or being replaced by technology altogether. However, that’s the wrong take on current modifications in education. In reality, digitalization should make teachers’ work much easier. Thus, technology will be handling most of the repetitive and analytical work. Now, teachers will better understand their students' needs and progress. Moreover, such information will be delivered to them by a computer. So, teachers will have more time for their students and immediate learning needs. So, each teacher should participate in the coming change in the education system as a relief for them. Related: Ten Ways Technology is Impacting Modern Education 5. Preparedness for the future Technology has already become an essential element of modern society. We rely on it in all spheres of our lives, including professional and personal. In the future, such technological reliance will only continue to rise. So why don't we prepare our children for that future? We want our children to succeed in life. School is the first step for that to happen. That’s where we should start introducing students to a new digital reality. To conclude Modern technology is already a part of our everyday lives. They have transformed how we communicate, receive information, work, etc. Education is just one more branch here. We also need to adapt it to the digital future we are heading for. Of course, there are certain bumps along the way. However, no changes come without challenges and pitfalls. Yet, the benefits of having technology in classrooms are greater than the hardships of bringing them there. Overall, it’s fair to acknowledge the ultimate advantages to education that only digitalization can give us. Thus, the future of learning seems to be more engaging, interesting, accessible, and adoptive.
