What is AI video creation, text-to-speech, and multimodal AI? A thorough explanation for beginners of the latest technologies that will color the future of the metaverse!

Hello everyone! I'm John, a veteran blog writer. The ever-evolving world of the metaverse and the AI (artificial intelligence) technology that supports it are really exciting! Recently, the fields that have been attracting attention are "AI video creation tools", "text-to-speech (speech synthesis) generators", and "multimodal AI", which integrates these. Sound difficult? Don't worry! In this article, I will explain what these latest technologies are and how they will change our creative activities and metaverse experiences in an easy-to-understand manner even for complete beginners. Recently, Chinese AI company MiniMax announced an AI video creation tool called "Hailuo Video Agent" and a multilingual text-to-speech generator called "Voice Design", and the progress of the multimodal AI technology became a hot topic. It's a hot topic right now!

Basic information: What are AI video creation, text-to-speech, and multimodal AI?

First, let's start by understanding the basics of what each technology is.

AI video creation tool: Create videos like magic!

As the name suggests, "AI video creation tool" isSoftware and services that use the power of AI to automatically or semi-automatically create videosFor example, you can simply pass the text you have written (called a text prompt) to AI, and it will generate a video that matches the content, or combine your own images and short clips to create an attractive video that looks professionally edited. Until now, video editing required specialized knowledge, expensive software, and above all, time. However, with AI video creation tools, anyone with an idea can create video content in a short amount of time and relatively easily. It's like a magic wand for creators! Apify's search results also include descriptions such as "Generative AI video creation tools speed up your editing process" and "Create 3–10 second animated Seedance videos from descriptive text inputs," which show its ease and potential.

Text-to-speech (TTS) generator: turn text into natural-sounding audio!

"Text-to-speech generator", also known as TTS (Text-to-Speech), isTechnology that converts written text into natural, human-like speechUnlike the old mechanical voices, recent TTS has evolved remarkably, and can now create narrations with rich emotional expressions and even conversations between multiple characters. As the description of Google's Gemini API states, "transform text input into single speaker or multi-speaker audio," its expressive power is wide-ranging. If you want to narrate a video but are not confident in your own voice, or if you want to publish content in multiple languages but don't have the budget to hire a narrator, TTS can solve such problems. The range of uses is endless, from turning blog articles into audio content to breathing life into game characters.

Multimodal AI: The future technology that connects everything!

And then there's "multimodal AI." This might sound a bit technical, butAI that can simultaneously understand, process, and even generate multiple different types of information (called modalities) such as text, images, audio, and video.This refers to the process of generating text that describes the contents of an image (image → text), generating images from text (text → image), understanding and summarizing the contents of a video, and editing videos based on voice instructions. As OpenAI's ChatGPT-4o is introduced as "multimodal model means it can ingest and generate text, image, audio, and video," it can be said to be an AI that transcends the boundaries of information. MiniMax has announced Hailuo Video Agent (video creation) and Voice Design (voice synthesis), and has positioned these as "Expanding Its Multimodal AI Capabilities," which is in line with this trend. It is expected that this will enable more intuitive and more human-like interactions with AI and advanced content creation.

The problems they solve and their unique features

These AI tools are primarily intended to solve the following problems:

Content production time and costs:Even if you don't have specialized skills, you can create high-quality video and audio content quickly and at low cost.
Representation limits:You can express yourself in a variety of ways without being affected by your own voice or the equipment you are using. You can easily create videos using avatars and use voices like professional narrators.
Improved accessibility:With features like audio description for the visually impaired and automatic subtitle generation for the hearing impaired, information becomes more accessible to more people.
Instant realization of ideas:It makes it easier to quickly put ideas into practice, accelerating the cycle of trial and error and stimulating creativity.

The unique feature is that"Automatic generation ability from text"In particular, "text-to-video" and "text-to-speech" are revolutionary in that AI can take over tasks that previously required specialized expertise by simply giving verbal instructions. This means that even people with no programming or design knowledge can now take on the challenge of advanced creative work.

Market trends and tool availability: Can anyone become a creator?

So how do we actually get hold of these amazing AI tools and use them? This is a very vibrant field, with many options on the market.

First,A wide variety of toolsOne point to note is that Apify's search results show a large number of tools, including "13+ Best AI Voice APIs," "10 Generative AI Tools," and "18 Popular AI Video Generators," creating a truly competitive landscape. Tools with their own unique characteristics, such as Synthesia, Lumen5, InVideo, Murf.ai, Tavus API, and Medeo AI, are appearing one after another, competing for functionality and ease of use.

AvailabilityRegarding this, there are mainly the following forms:

Free or freemium model:You can try out the basic features for free, and paid plans are available for more advanced features and usage. For beginners, it's the best way to get started. Some, like Seedance 1.0, advertise themselves as "Free AI Video & Image Generator."
Subscription model:This is a monthly or yearly subscription plan, and is intended for those who plan to use it for commercial purposes or create large amounts of content.
API delivery model:These are provided to developers as APIs (Application Programming Interfaces: mechanisms for software integration) that allow developers to incorporate AI functions into their own services and applications. Examples include the Tavus API and Gemini API.

As you can see from information such as "Browse 218 Text to video generator AIs" and "Browse 334 Text to speech AIs," there are a lot of options.AI-based content creation is no longer something reserved for a select few experts; it is becoming accessible to a wider range of people.It shows that the era when "anyone can become a creator" may be just around the corner. However, the fact that there are so many tools means that you also need to be able to discern which ones suit you best.

How the technology works: How does AI create content?

Many people may wonder, "How can AI automatically create videos and audio?" Here, we will explain the technical mechanisms behind this in as easy-to-understand a way as possible. The key words are "Generative AI" and "Machine Learning."

Behind the Scenes of AI Video Generation

AI video generation tools are mainlyLearn large amounts of video data and corresponding text descriptions (e.g., "A dog walking on the beach at sunset")Through this learning process, the AI grasps the pattern of "what kind of visual characteristics should be generated when what kind of text is input." This is similar to how humans learn how to draw by looking at many pictures.

Specific technologies often used are neural networks (mathematical models that mimic the neural circuits of the human brain) such as GANs (generative adversarial networks) and diffusion models. These excel at "generating" realistic images that look like the real thing. When a user inputs a prompt such as "The adventures of a flying cat," the AI mobilizes all of its learned knowledge to assemble a plausible image pixel by pixel. The Wikipedia page for "Text-to-video model" also states that "it uses a natural language description as input to produce a video relevant to the input text," and this combination of natural language processing and video generation is the core of the model.

The Magic of Text-to-Speech (TTS)

TTS technology is also based on having AI learn a large amount of voice data and the text data that corresponds to that voice.Learn the relationship between the sequence of letters and how they are actually pronounced, with their intonation and rhythm..

Recent high-quality TTS uses deep learning models such as WaveNet and Tacotron. These can capture even the subtle nuances of the human voice and synthesize very natural and smooth voices. In addition, there are an increasing number of tools that allow you to adjust the tone of voice, speaking rate, emotional expression, etc., making it possible to create more expressive voice content.

Multimodal AI collaboration

Multimodal AI takes these individual technologies a step further.Allowing different types of data to be handled on the same levelFor example, it combines the "ability to see" cultivated through image recognition, the "ability to understand words" cultivated through natural language processing, the "ability to speak" through voice synthesis, and the "ability to create images" through video generation.

To achieve this, it is important to have technology that converts each data format (text, image, voice, etc.) into a common "representation method" that AI can understand. Then, advanced AI architectures are used that process the information in an integrated manner and generate appropriate output in one modality in response to input from another modality. It is precisely this multimodal capability that allows ChatGPT-4o to answer questions about images by voice.

Development team and community: Who is behind these technologies?

With such innovative technology, there are many talented developers and an active community behind it.

First,Big Technologyare strongly leading research and development in this field. Representative companies include Google (Gemini API, Veo, etc.), OpenAI (DALL·E, Sora, ChatGPT), Meta (Facebook AI), and Microsoft. These companies have abundant financial resources and excellent teams of researchers, and are involved in a wide range of research, from basic research to the development of practical tools.

On the other hand,Specialized startupsMany new companies have also appeared, offering unique features and tools that meet specific needs. Synthesia, Tavus, Murf.ai, Seedance, and Medeo AI, which are listed in Apify, are also tools developed and provided by such companies. MiniMax, a Chinese startup, is also attracting attention for developing its own AI models. These companies are creating innovation with a different perspective and speed than the major companies.

Furthermore, Open Source CommunityThe contributions of researchers and developers cannot be ignored. Researchers and developers are publishing their results, and people around the world are improving them and developing new tools. This is democratizing technology and allowing more people to benefit from AI.

And we must not forgetuser communityCreators who actually use these tools to create content exchange information and share how to use them on social media, forums, and specialized blogs, and sometimes provide feedback to developers, which helps the tools evolve into something even easier to use and more convenient. For example, interactions between users can sometimes lead to new ways of using the tools, as seen in posts such as "Some fun content I created using text to speech video..." in Facebook groups.

These diverse players influence and support the development of AI content generation technology.

Specific examples of use and future prospects: How will our lives change?

Risks and Cautions: What you need to know

AI content generation technology has great potential, but it also comes with some risks and precautions to be aware of.

Limited quality and artifacts:AI-generated videos and audio are improving day by day, but sometimes they can have unnatural movements or facial expressions (the "uncanny valley" phenomenon), strange pronunciation, or content that doesn't fit the context. It can be time-consuming to always check the generated content and correct it if necessary.
Ethical issues (deepfakes, misinformation):There is a risk that these technologies will be abused for malicious purposes, such as to create fake videos of specific individuals (deep fakes) or to spread false information as if it were fact. The literacy to distinguish the authenticity of generated information will become increasingly important.
Copyright and License:When AI learning data contains copyrighted material, there is still some legal ambiguity regarding what happens to the copyright of the generated content. When using it commercially, it is necessary to carefully check the terms of use of each tool to avoid copyright infringement.
Impact on creators' work:There are concerns that the advancement of automation by AI will take away some traditional creative jobs (illustrators, narrators, video editors, etc.), but on the other hand, it will increase the demand for creators with new skills to use AI.
Bias and Fairness:Because AI makes decisions based on training data, if there is bias in the training data, the generated content may reflect that bias. For example, it may result in content that reinforces stereotypes against a particular gender or race.
Tool evolution and dependency:Technology evolves so quickly that the tools and techniques you learn today may be outdated tomorrow. Also, if you become too dependent on a particular tool, you run the risk of not being able to respond if that tool is discontinued.
Regulatory Developments:Discussions on establishing laws and regulations regarding AI are underway in each country. It is necessary to consider the possibility that future regulations may impose restrictions on how tools can be used and the content that can be generated.

It is essential that we understand these risks and use technology in a responsible manner.

Expert opinion and analysis: What does the industry think?

Experts and industry analysts in the field are generally optimistic, but also cautious, about the future of AI content generation technology.
