ASR in a Noisy Environment

On September 19, 2023

Automatic Speech Recognition (ASR) is a powerful technology that uses advanced machine learning and artificial intelligence techniques. ASR improves the quality of service while reducing its cost. Modern ASR engines are being trained to recognize different languages and dialects. They can also be trained for an industry-specific vocabulary. Overall, modern ASR engines are very accurate […]

Cocktail party and crosstalk

On September 9, 2023

The cocktail party problem is one of the oldest problems in the arena of signal processing. The problem is describes as follows: in a cocktail party there are many people talking. All their voices are mixed in the air and the people listening will hear all the voices blended together. Nevertheless, in most cases, the […]

Pincer movement to cancel noise

On September 9, 2023

Noise can be very difficult to cancel especially in crowded environments like call centers and shared workspace. The noise in such locations has two main components: 1- Office sound and static ambient noise 2- Clear voices of other people talking around you While the first component does not sound like human voice, it can be […]

AI, Can you identify echo?

On July 5, 2023

Acoustic Echo in phone calls is caused when audio that is being played on the loudspeakers is then picked up by the microphone and afterwards transmitted to the far-end person who is talking. As a result the far-end talking person will hear himself/herself in a delay. When echo appears in a phone call it is […]

Noise Cancellation for DeskPhones

On December 5, 2021

The demand for Noise Cancellation in phone calls is constantly increasing. The main reason for the increasing demand is the improvement in technology that is now able to provide better quality than the quality that could be provided few years ago and this technology keeps improving every day. The same principle applies to any other […]

Don’t burn your CPU

On September 30, 2021

The Central Processing Unit (CPU) is the heart of any computing system including, of course, your PC/laptop. The most important differentiator between PCs is the difference in the power of their CPU. On average, the power of the CPUs increases over the years. It is interesting to note that fifty years ago George Moore anticipated […]

CPU vs. GPU

On August 1, 2021

Background When developing a new application, especially an Artificial Intelligence (AI) based application, one of the questions that comes into mind: should the application be executed on the CPU (Central Processing Unit) or the GPU (Graphical Processing Unit). CPU is the main processing unit in every computer while GPU is a separate processing unit that […]

AI, Can you identify who is speaking?

On June 13, 2021

The voice of each person sounds different and has its own unique characteristics. These characteristics can be divided into linguistic vs. non-linguistic and also to auditory vs. acoustic ones. This fact is being used for decades in forensic cases. When needed, the speech is being analyzed using different methods to provide forensic proof. For example, […]

Voice bots in call centers

On May 13, 2021

An emerging technology for call center is the usage of voicebots. The main purpose of introducing bots is to reduce the load from the call center agents. Voicebots are usually the first to receive the telephone call from the customer, provide initial assistance and if required route the call to the best human agent group […]

Profile-Based Noise Reduction

On November 19, 2016

Background In this post we will review the evolution of this technology over the years. Initially this technology was introduced under the name of personal noise reduction. Few months later the concept of out-of-the-box deployment with generic profiles was introduced. At the next step, we have renamed this technology to “profile-based noise reduction” based on […]
