Twilio Video Noise Cancellation requires you to host and serve the Krisp audio plugin for Twilio as part of your web application. Note that all of these steps happen on your device, with almost no latency, and no media sent to a server. During this step, the AI-based noise cancellation algorithm removes unwanted sounds like barking dogs, construction noises, honking horns, and coffee shop chatter.Īfter the preprocessing step, the audio is encoded and delivered to the end user. The plugin needs to be loaded alongside the Twilio SDK and runs as part of the audio pipeline between the microphone and audio encoder in a preprocessing step. It’s with this technology that we created the Krisp Audio Plugin for Twilio Video, a lightweight audio processor that can run inside your client application and create crystal clear audio. Using tens of thousands of hours of audio recordings, Krisp.ai has created a sophisticated Deep Neural Network that can differentiate between background sounds and the human voice. This feature is available for all customers using Twilio Video Group Rooms. Twilio has partnered with Krisp Technologies Inc., a leading technology vendor for noise suppression, in order to provide Twilio customers a best-in-class audio experience. You can remove hundreds of unwanted types of background noises from a video room using the Krisp Audio Plugin for Twilio Video to power AI based noise cancellation.

Moreover, since the entire processing takes place locally on your computer, and the service does not require sending your data to its servers for processing, you can rest assured with your audio not ending up on some random servers. The noise-canceling process takes place before the audio reaches the service, which opens up the option to use Krisp with almost any app or service you want. Basically, it adds a virtual microphone between your device’s physical microphone and the app you are using - to suppress the noise from your microphone to the person on call at the other end, and a virtual speaker between your device’s physical speaker and the app in use - to suppress the noise coming from the person on call at the other end to your speaker. ![]() What’s interesting about Krisp is that it works as an additional layer between your device’s microphone/speaker and the app or service you are using. Besides that, the tool also gives you the option to reduce noise at the other end of the call, meaning, if the person on the other end of the call is in a noisy environment, you can enable the option on your app to suppress noise coming from their end. Once that’s done, it then removes the waveform of noise from the audio to offer a clearer audio experience. For this, it relies on Artificial Intelligence to create a KrispNet DNN (Deep Neural Network) that helps it recognize the voice of the person on the microphone and differentiate it from the noise. To give you some background, Krisp is a noise suppression tool that mutes background noise during calls. So, let’s dive in and see what Krisp is and how to use it. And now, we have another company, Krisp, offering its services for free or discount for the next 6 months. Building upon the same, we recently saw companies like Cisco, Google, Microsoft, and a few others, offering their video conferencing solutions for free or at a discounted price, to encourage remote work. With governments across the world suggesting its citizens to avoid going out and staying at home as much as possible, taking into account the purview of coronavirus outbreak, we now have more and more companies and organizations, who have also started asking their employees to avoid commute and work from home instead. ![]()
