Krisp alternative
A Krisp alternative built into the call.
Krisp is a good product. If you want a noise-cancelling layer on each person’s computer, or an SDK to wire into a pipeline you run yourself, it is worth a look. Teams searching for a Krisp alternative usually have a different problem: the noise is on calls where nobody is sitting at a desk, such as an AI voice agent answering someone on a busy street.
VocalLabs noise cancellation is part of the platform the call already runs on. Switch it on for an AI voice agent or a VocalStack Voice line and every voice on the call is cleaned up in real time, whatever platform, phone or headset is on the other end.

What a caller’s voice is up against.
Normal conversation sits at 60 to 70 decibels. A caller on a street, at a match or near an ambulance is talking over sounds far louder than their own voice. A person on the other end strains to hear; a speech recognizer guesses.
- Normal conversation
- 60–70 dBA
- Motorcycles and dirt bikes
- 80–110 dBA
- Sporting events and concerts
- 94–110 dBA
- Sirens
- 110–129 dBA

Krisp vs VocalLabs: where the noise comes out.
Both remove background noise. The difference is where they sit, and so which calls they reach without extra work.
| Krisp (agent-side app) | VocalLabs (in the call pipeline) | |
|---|---|---|
| Where it runs | Between the agent’s headset and the softphone, CCaaS or meeting app | In the voice platform that carries the call |
| Built for | People on calls and in meetings | AI voice agents and calls running on VocalStack Voice |
| Calls with no one at a desk | Needs Krisp’s developer SDK, integrated by you | Covered: the agent is software, and so is the noise removal |
| Platforms and headsets | Sits on top of softphones without a telephony integration | Any platform, any headset, any setup |
| How it is bought | Per user or per agent seat; Call Center AI CC Core is listed at $15 per agent a month, billed annually | Part of a VocalLabs voice agent or VocalStack Voice line, or as an SDK; quoted on request |
| Also in the box | Meeting notes, transcription, accent conversion, voice translation, agent assist | The voice agent itself: telephony, speech models, barge-in, handoff, 20+ languages |

Where noise cancellation sits on a voice-agent call.
On an AI voice agent call there is no agent desktop to install anything on. The noise has to come out in the pipeline, before the speech reaches the models that have to understand it.
- 01CallerOn a street, in a car, on a shop floor.
- 02Carrier or SIPAny platform, any phone.
- 03Noise cancellationVocalLabs, in real time, for every voice on the call.
- 04Speech recognitionGets the speech, not the traffic.
- 05Model and voiceAnswers what was actually said.
- 06A person, if neededWarm transfer with a clean recording and transcript.
- Nothing to install
- A setting on the line, not an app on every machine. New agents and new numbers are covered from the first call.
- Cleaner input for the AI
- Better audio means better inputs for transcription, analytics and the models that act on them.
- Every voice, not just one side
- Noise is removed for everyone on the call, not only for one side of it.
- Your own apps too
