Azure Cognitive Services represent a suite of cloud-based APIs developed by Microsoft to integrate artificial intelligence capabilities into applications. These services allow you to add functionalities such as image recognition, natural language analysis, machine translation and voice recognition to your solutions, without the need for in-depth machine learning skills. In this article, we'll look at what Azure Cognitive Services are, what capabilities they provide, and what advantages they offer businesses.
For some years now, the modern business landscape has been making the most of the potential of cognitive computing, which increases process efficiency, allows accurate data analysis and improves customer interactions, as well as offering a series of other advantages. However, taking advantage of these benefits is impossible without the use of comprehensive cognitive services.
In 2015, Microsoft Corporation released a set of intelligent technologies, calling it Project Oxford. This project included solutions for performing cognitive tasks, such as face detection, voice recognition, image categorization, and language understanding.
With the expansion of the product, it was renamed to Azure Cognitive Services and today it is one of the most efficient services of its kind. These tools of Microsoft Azure work across all programming platforms and languages, helping to incorporate AI functionality into various applications with minimal effort and coding.
Thanks to these APIs, developers can quickly enrich their software with the ability to see, speak, hear, understand and make decisions, without worrying about developing complex solutions for implementing these functions in their applications.
But what are they specifically? How do they work? Let's find out below.
Before delving into Azure Cognitive Services, let's try to understand what cognitive computing and cognitive services in general are.
Cognitive computing represents the use of advanced technologies to simulate human cognitive processes, that is, the way in which people think, learn, and solve problems. The technologies involved in this field range from artificial intelligence (AI) to signal processing, from machine learning to neural networks, to virtual reality and other similar technologies. These tools work together to mimic human comprehension and reasoning abilities, allowing computers to tackle complex tasks more efficiently.
The main objective of cognitive computing is to simplify the creation of intelligent applications, eliminating the need for deep programming expertise. In essence, it aims to democratize access to advanced technology, allowing even those without technical training to exploit the potential of artificial intelligence and other cognitive technologies to develop innovative solutions.
Cognitive services, on the other hand, are a set of APIs (Application Programming Interfaces) and toolkits designed to support the development of applications that can process unstructured data and transform it into useful information and insights and allow developers to easily integrate cognitive functionality into their applications, such as voice recognition, sentiment analysis, face detection and the ability to generate recommendations based on user behavior, without the need to build these systems from scratch.
And Azure Cognitive Services are exactly that: predefined APIs available to developers to help them create intelligent software applications without the need for direct skills in machine learning or artificial intelligence, which allow developers to easily integrate cognitive services into their applications.
With cognitive services you have access through simple HTTP endpoint to intelligent features, such as understanding and the interpretation of pictures, text recognition or searching on the web, using natural communication methods.
In machine learning, the developer must collect the training dataset, test its validity using appropriate models and then evaluate the results. This process requires knowledge about the different models and concepts of machine learning. However, with Azure Cognitive Services, the task becomes easier because the developer only needs to provide the data, while everything else, such as training the data and selecting the best models, is managed by the cognitive services provided.
Like all Azure services, Cognitive Services are also distributed across all Microsoft Data Centers, so depending on the country where the program will be used, you can decide where to allocate the service. A direct need deriving from the relocation of services is the possibility of being able to set a different culture for each API. To see which ones are available, you can view the list at the following links, which lists support for each individual Cognitive Service.
We have created the Infrastructure & Security team, focused on the Azure cloud, to better respond to the needs of our customers who involve us in technical and strategic decisions. In addition to configuring and managing the tenant, we also take care of:
With Dev4Side, you have a reliable partner that supports you across the entire Microsoft application ecosystem.
Now that we have a clearer general idea of what these cognitive services are, it's time to go into a little more detail about what they offer. Azure Cognitive Services of Microsoft Azure can be grouped into 5 categories that group APIs by macro functionality and are respectively:
Vision services can analyze visual content such as images, GIFs and videos to identify the objects present. These services may allow apps to detect and group faces or objects based on distinctive characteristics.
Among Vision's services we can find:
Speech services are used to enable voice processing in apps, allowing speech to be converted into text and vice versa, in addition to translating text into other languages and identifying speakers.
Speech's main services are:
Language services are primarily used to analyze text and extract meaning from it.
Language services include:
Decision services analyze data and draw patterns to allow faster, more precise and efficient decisions to be made in different contexts.
These include:
The last type of Cognitive Services offered by Azure is related to the way in which we search for information online. Even if Bing is not as popular as Google, the Microsoft search engine continues to defend itself using powerful algorithms based on artificial intelligence, capable of searching, comparing results and selecting only those that are relevant to your requests.
There are numerous advantages offered by the use of Azure Cognitive Services to organizations that want to exploit the potential made available by the latest technologies in the field of cognitive computing. In the list below, we will limit ourselves to mentioning just a few of the main benefits of the service and the many solutions it offers:
Azure Cognitive Services can help an organization in multiple use scenarios and the stories of large companies that have successfully implemented their functionality within their digital infrastructures are numerous.
So, for those who prefer to learn about a product through its success stories, below we provide some examples of real use cases by large companies that have managed to benefit greatly from the implementation of the Cognitive Services of the Microsoft cloud platform within their digital infrastructures:
Now let's talk about the costs: the pricing of Azure Cognitive Services is extremely complex because each service has its own unit of measure and rate, such as the number of images analyzed, documents processed, characters translated or hours of processed audio.
However, there are some common characteristics that can be identified and that will be the subject of this section, so that we can get as clear a general idea as possible of the pricing of Azure Cognitive Services.
Most services are billed on a consumption-based basis, meaning you pay based on actual usage. The costs then accrue based on the number of API calls, processing hours, or volume of data processed.
Some services may also offer different price levels based on volume, with for example, costs per call that may decrease as the data processed increases, as in the case of Computer Vision, Face API, Text Analytics or Translator.
Prices may also vary depending on the geographical region in which the services are used, reflecting the differences in the operating and infrastructure costs of the various areas, as well as the exchange rate of the currency used for payments. It is therefore important to consider the location of your users and data when choosing a region as it may influence the overall cost of the service.
For those interested in wanting to test the functionality of Azure Cognitive Services before committing themselves financially, many of the services offer a free monthly fee or a free trial that allows you to experiment without initial costs, useful for developers who want to test and develop applications without worrying about their budget.
For those who want to take the next step directly, with the convenient calculation tool made available on the official Azure page (which you can find hither) it is possible to start making a first estimate of the costs for each individual service.
Azure Cognitive Services are, ultimately, a very useful set of REST APIs and toolkits that can help developers create intelligent and smart apps. Anyone with basic knowledge of programming and API calls can use them to improve and expand different applications, limited only by their creativity.
With these tools, we can create systems with human capabilities capable of seeing, listening, speaking and understanding people in their natural language, using the same communication method to relate to them. By using cognitive services, we can not only use them for development purposes, but also in other fields such as making the app more secure, providing better customer support, and much more.
Day after day, exploiting the capabilities of cognitive computing is becoming an increasingly crucial element in the digital strategies of companies of all sizes that wish to keep up with the times.
Anyone who has not yet taken the necessary steps to put themselves in a position to take advantage of the latest technological discoveries is increasingly at risk of finding themselves in an uncomfortable position of stagnation in the future and Azure, with its Cognitive Services and its more than 200 services, could be an excellent first step to start moving in the right direction.
