High Accuracy Speech Analysis – VisionAI

Introducing state-of-the-art High Accuracy Speech Analysis services under our VisionAI platform where our customers can add powerful speech analysis capabilities into their own apps!

What is Speech Analysis

High Accuracy Speech signal analysis can be defined as the process of extracting information related to a speech signal (i.e from a recording). This process is based primarily on the method of speech preparation, the study of which covers a wide range of subjects, from linguistics and articulatory phonetics to signal processing and source coding.

Speech cognition variables exist in different languages, dialects, accents, while the vocabulary of speech is growing day by day. There are more complex variations on the surface of the speech signal in the form of different dimensions, duration, pitch, and speaker variability.

Applications Of Speech Analysis:

There are so many applications of High Accuracy Speech Analysis some of them are given below:

Speech enhancement:

Improving speech signal quality by filtering and separating the noise from the speech segments.

Text To Speech:

It is difficult to synthesize natural speech from text, to make speech perfectly natural with emotions.

Detect sound activity:

Identifying classes in an audiovisual forum where only speech exists, ignoring non-speech and silent classes.

Speech Recognition:

Converting speech gestures to text is still a challenge in different situations, recognizable can be word-dependent or independent.

Search Keywords:

Identify specific keywords throughout the speech.

Speech editing:

Editing a speech, such as changing its mood, accent, or speech by a different speaker.

Distinguish from the speaker and the identity of the speaker:

Directing is dividing the speech signal into classes belonging to different speakers while identifying the speaker to identify who is speaking at a particular time.

Classification of emotional speech:

Identify speech emotions such as happy, angry, sad and anxious.

Audio Source Separation:

Isolation of mixed speech signals such as speech overlapping with different speakers or noise.

Noise in speech and text:

Noise is any unwanted signal that distorts the original signal. Adding noise to speech is very different from adding noise to text.
Gave a speech signal with amplitude [n], where n is the sample index, noise is another signal, w [n] which interferes with speech. The hint of a noisy speech can be seen as:

u[n]=s[n] + w[n]

The plot is to make noise in the time and frequency domain. Noise in speech signals modifies the entire signal and makes it difficult to analyze and extract speech classes. There are speech enhancement algorithms to reduce the noise component and improve speech efficiency.

When the text is punctuated, noise can occur in the form of incorrect and missing words that can either change the meaning of the sentence or make meaningless sentences. For example:

Original text sentence: ‘will we ever forget it’

Noisy text sentence : ‘will we never forget it’

In this noisy text, the noise always changes from the form of the word “ever” to “never”, which changes the meaning of the sentence.

Another form of noisy text: ‘Will we never forggt it’
In the above-mentioned noisy text, the sound of noise has changed from the word “forget” to “forggt”, which makes the sentence meaningless due to the wrong words “forggt”.
Therefore, it can be seen that adding noise to the speech distorts the whole signal while distortion in the text is a matter like missing a letter / word or misspelling it.

Original and Noisy Speech

Challenges in High Accuracy Speech and Noise Analysis:

Speech and noise analysis applications are quite difficult to solve. External factors that further complicate speech and noise analysis produce a variety of noises, including speech and text. To solve this problem, various different signal processing, neuroscience-based methods, monitoring, and non-monitoring machine learning techniques are explored. Due to the erratic nature of speech gestures, deep learning-based methods have been successful for a variety of applications.

High Accuracy Text Analysis – Vision AI

Introducing state-of-the-art High Accuracy Text Analysis services under our VisionAI platform where our customers can add powerful Translation (100+ languages supported) and Sentiment analysis functionalities into their own apps!

Introduction

Text analysis allows companies to automatically categorize the information from text such as emails, support tickets, product reviews, and survey responses. The best text analysis techniques include Emotion Analysis, Title Detection and Keyword Search.

Businesses want to extract specific information, such as keywords, names, or company information. They even want to categorize text with tags by title, or categorize it as positive and negative.

In other words, if we want text analysis software to perform the required tasks, we need to teach machine learning algorithms on how to learn how to analyze, understand, and derive meaning from text. But how?

The simple answer is to tag text examples. Once a machine has enough examples of tag text, it is able to distinguish and associate algorithms between pieces of text, and it can even begin to make predictions.

Every minute 156 million emails and 456,000 tweets are sent. There is a huge amount of data to implement it, and it is impossible for humans to do it alone.

If machines were made fully responsible for sorting data using text analytics models, the benefits to the business would be enormous.

What is Natural Language Processing?

Understanding natural language allows machines to read text (or any other input such as speech) by mimicking the human ability to understand natural language such as English, Spanish, Chinese etc.

As a technology, natural language processing has advanced over the last ten years, with products such as Siri, Alexa and Google’s Assistant enabling NLPs to understand and respond to user requests.

Applications are in customer care, insurance (fraud detection) and contextual advertising.

Today’s natural language processing system can analyze innumerable text-based data without fatigue and in a consistent, unbiased manner.

They understand concepts within complex contexts, and key language understandings that can extract, or summarize, key facts and relationships.

Unstructured data generated each day, from electronic health records (EHRs) to social media posts, this form of automation has become important for efficiently analyzing text-based data.

Text classification

Text classification is the process of assigning predefined tags or categories to unstructured text.

It is so versatile and can organize, configure and classify anything to provide meaningful data and solve problems.

Sentiment Analysis

Emotions are essential for effective communication between humans, so if we want machines to handle texts in the same way, we need to teach them how to detect emotions and make text positive, negative or non-existent.

This is an automated process of understanding opinions about a given topic in written or spoken language.

For example, companies are able to flag complaints or urgent requests by analyzing emotions, so they can be dealt with quickly – and perhaps a PR crisis on social media can be avoided.

Other uses for rating emotions include assessing brand reputation, conducting market research, and improving product from consumer feedback.

Analyzer models use a wide range of text and natural language technologies from EBORE APPS. For selected languages, the APIs can analyze and score any raw text you provide, returning results directly to the calling application.

Topic Analysis

Topic analysis is also an example of text classification. 

The model can categorize feedback into tags such as Customer SupportEase of UseFeatures, and Pricing. For example:

Structure Of Topic Analysis

Detection of intention

The model can also be used to detect intent within the text e.g. to better understand consumer feedback about a product.

From the intention to complain about a product to the intention to buy any product.

Extract the key phrase

Automatically extract key phrases to quickly identify key points. For example, for input text “food was delicious and amazing staff” the API returns key conversation points: “food” and “amazing staff”.

Language detection

Language Detector automatically categorizes text based on its language. This can be very useful for ticket routing.

For example, if you are an international company, you can route tickets to local language teams that understand them.

Identity of name entity

Identify and classify organizations in your text as people, locations, organizations, date/time, quantity, percentage, currencies, and more.

VisionAI gives you access to pre-trained high accuracy text analysis models that can help you analyze your data right now.

High Accuracy Image Analysis – VisionAI

Introducing high accuracy Image Analysis technology in our VisionAI platform where our valuable customers can process and infer important information from the image.

Image processing is the process of converting an image into a digital form and doing some work on it in order to get a better image or get some useful information from it.

Image processing systems typically involve the processing of images as 2 or 3-dimensional signals, while pre-set signal processing methods are applied to them.

The two methods used for image processing are analog and digital.

Analog or visual technique of image processing can be used for hard copies such as print outs and photographs. Image analysts use a variety of basic principles of interpretation using these visual techniques.

Why images matter

Social media and the web as a whole are more overlooked, brands cannot rely solely on text when analyzing social media data to better understand their audience.

Here’s what Gartner said about the importance of image analytics:

“We do expect multimedia posts to become the predominant type of post on social media. Even the text that accompanies those posts is getting shorter and shorter… It becomes increasingly important for companies to be able to understand what’s going on in those images.”

 Jenny Sussin, VP of Research at Gartner

According to Mary Meeker, more than three billion photos are shared daily on social media.

Many of these images include brand products and logos, but 85% of them do not include a reference to the text of the brand.

Without image analytics, brands miss out on a great deal of social conversation about their brand, products, consumers, and competitors.

For Example take a look at this Facebook post from Roger Federer:

Whether Nike is paying or sponsoring Roger for posting about the brand, image analysis technology can help them know exactly when and how Roger is representing the brand.

This is just one example of the power of this deep learning based technology and why it matters to brands.

The ability to recognize the brand logo in images may seem like the technology of the future, but in reality it is a fundamental function of image analysis.

Image Analysis

Image analysis involves incorporating an image into the basic components in order to extract meaningful information.

It may include tasks such as finding shapes, detecting edges, eliminating noise, counting objects, and calculating structural analysis or image quality data.

Image analysis is a broad term that covers a variety of techniques that typically fit into these subcategories.

  • Image enhancement to create image for display or analysis.
  • Isolate letters and objects of interest.
  • Noise removal using shape filtering or deep learning.
  • Analysis of the region to extract statistics.
Example of Image Analysis
