Working From Home? Mute background noise in any communication app.

We Built Krisp to Enable People to Work from Anywhere

The world is shifting. Remote work is revolutionizing how we work and connect with our colleagues. Krisp brings freedom and flexibility to people and empowers them to be more productive and Professional when working remotely.

Krisp is in The Center of The Remote Work Revolution

We live by our mission, and enabling people to work from anywhere starts with our own company. We are a distributed team and thus we experience the challenges of remote work every day. We’re building technologies and a product we believe in — as well as a strong, diverse team of curious people who want to do the best work of their lives.

Discord relies on Krisp's AI-driven Deep Neural Network to ensure clear conversations for its 130 million users.

As the rise of remote work continues to revolutionize how people connect and collaborate, navigating the inevitable challenges that arise working in less predictable environments has strained productivity and professionalism. This issue has only been compounded by the record-breaking numbers of people who, due to the COVID-19 pandemic, are relying on voice communication apps to work, learn and play.

If there is one phrase that best encapsulates life in 2020, it would probably be “could you please mute your mic?” It’s hard enough for people to hear each other speak -- distributed teams -- let alone be subjected to all the background noise and packet loss during calls.

The massively popular VoIP application and digital distribution platform Discord had been recording a massive uptick in traffic on their servers, especially in Italy, France and Spain, coinciding with the lockdown measures being put in place there. This drove the impetus to cleaning audio conversations even more clear for their 250 million accounts and 14 million daily active users. Luckily, Discord has found a solution in the form of Krisp AI background noise suppression technology.

While Krisp’s solution seems simple, their technological approach is unique from anything that currently exists in the industry. Contemporary audio suppression features, such as those in mobile phones, typically use multiple microphones placed at different locations around the device to differentiate sound coming from a speaker’s voice and their environment. Conversely, Krisp developed a Deep Neural Network (DNN) called “KrispNet” that uses machine learning to separate and suppress background noise from human voices. When users click the mute button inside the Krisp app, every three-millisecond audio frame coming from their microphone is processed through the neural network and outputted as clean speech in real-time. All audio processing happens locally on users’ computers, protecting privacy as no data is sent to external servers. 

Describing how Krisp cleans up background noise, Discord content writer Nelly compares this AI-powered app which uses machine-learning to adapt to speakers voices to “a vacuum running in the background; slam a door; ruffle a bag of chips; keep using your really loud keyboard your friends complain about. They won’t be able to hear it.”
