Still don’t know what Audio Recognition is?

Today, with technological development and the arrival of Artificial Intelligence, it is possible in a few seconds to identify the nature of a sound through Audio Recognition solutions.

What is Audio Recognition

Audio Recognition is that element of Artificial Intelligence that allows you to have machines capable of identifying sounds of any type: people who speak, animals, environmental sounds, etc.

Starting from a sound recording, Audio Recognition simulates the human process of data processing, transforming it into information. In a few seconds it can return useful elements such as identity of the person, age, gender.

The differences between Audio Recognition and Speech Recognition

In the past, speech recognition was identified as the process by which human oral language is recognized and processed through a computer. Today we can attribute this part to Speech Recognition. In fact, while the latter refers to the recognition and processing of human language, Audio Recognition is able to identify and process sounds of any type.

Speech Recognition examples

Speech Recognition is used for:

• automatic call centers to recognize and transcribe what people have said on the phone
• help desk
• voice transcription meetings

In addition, it is increasingly used in the medical field to replace keyboards or touch screens, in “hands-free” devices or in function control interfaces or for browsing content for mobile devices, PCs.

Uses of Audio Recognition

Sound recognition software is useful in various areas such as:

• Cinema and music
• Acoustic oceanography for the identification of animal species
• Public and private security (for example for the automatic identification of alarms of surveillance systems or for the identification of criminals through wiretapping)
• Assistance to disabled or elderly people with hearing problems

The developments of Audio Recognition in public safety

Each audio can leave multiple “voiceprints” attributable to different information. Just like the fingerprint, it provides the investigator with information on the suspect of the crime, tracing the DNA and therefore the identity of the person.

Let’s imagine that there is a “bank of voices”. Thanks to it we have a database with the identities of known criminals, of which we can compare the voiceprints with the audios of anonymous wiretaps. How many arrests were not possible because the investigator or consultant could not identify the identity of the intercepted person?

With technology we have the ability to create a database far superior to the experience and memory of the individual investigator. The second advantage is that with an Audio Recognition software it is possible to separate the voices from the background noise. Often, in fact, wiretapping recordings have low quality sounds, in which voices are too low and incomprehensible to the human ear due to disturbing noise. The software can improve the quality of speech and still identify the identity of the people who are speaking.

The third advantage, not to be underestimated, is that scientific evidence can be shown during the process as to why a person actually corresponds to the voice in the recording.

Pragma Etimos Solutions

We develop Audio Recognition software for the definition of “voice prints” and the recognition of voices extracted from audio files regardless of source and quality. Our solutions are tailor-made to the customer and can be integrated with any technologies already in use.

In particular, the services we offer are:

• Voice print identification
• Speaker Diarization
• Identification of the language
• Gender identification
• Age estimate
