Transcription in noisy call centers

Today, modern call centers are deploying sophisticated software components to help them improve customer experience, increase productivity and comply with new regulations. One of the enablers for these new capabilities is the requirement to have a reliable and accurate analysis and transcription of the agent’s voice. Such analysis and transcription is used for many purposes […]

Noise map for call centers

Call centers suffers from significant ambient noise that is originated from multiple locations like: Other agents talking in the background. The supervisor/team-leaders shouting to instruct or enthuse the agents. A nearby gathering in the coffee corner. Such noise reduces the quality of the calls and directly impacts customer satisfaction. In addition the existence of […]

Noise cancelling headsets for call centers, what’s next?

Noise removal in a call center environment is a challenging task. As opposed to non-human ambient noise like street noise and car horn, the background noise in call centers is actually human voices of people talking in the background. When performing noise removal in a contact center environment the challenge is to identify which of […]

How to evaluate an echo cancellation algorithm?

 When you encounter an echo problem in your application, network or devices it is obvious you need to introduce an echo canceller.  Your next step is to explore at least two possible locations for performing the echo cancellation: cancelling the echo on the client side or doing it on the server side. The decision […]

DC offset and Audio Filtering

In this post we describe a phenomena called “DC offset” in audio signal and its impact on the quality of audio filtering like noise reduction, echo cancellation and automatic gain control. We say that a signal has a DC offset distortion when the mean amplitude of its waveform is not zero. A normal voice is a symmetric sine signal […]

Acoustic Echo Cancellation Vs. Acoustic Echo Suppression

Echo is a known problem in telephony and when it appears it dramatically reduces the quality of the audio. In some cases the echo can even turn out to howling effect that generates a deafening noise. To familiarize yourself with the basic terms that relates to echo cancellation, you are invited to read our blog-series […]
