# Noise Cancellation for Real-Time Voice Channel

### **Overview:**

\
Integrate Third party noise cancellation technology into iX Hello Customer’s real-time voice channel to enhance **voice quality and user experience**. This integration ensures clear, uninterrupted voice communication between users and AI voicebots by filtering out background noise automatically.

#### **Feature Description:**

#### iX Hello Customer Voice Channel: Noise Suppression Integration

* The iX Hello Customer voice channel will integrate **third-party tools** via **SDKs/APIs** to enable AI-powered noise suppression for live voice interactions.
* Audio streams will be processed **in real time**, removing unwanted ambient sounds such as:
  * Background chatter
  * Keyboard typing
  * Fan noise
  * Other environmental disturbances
* Only **clear, natural human speech** will be transmitted to participants.
* The noise cancellation feature will operate **seamlessly within the existing real-time voice flow**, ensuring:
  * No perceptible latency
  * No impact on system performance
* Users will have the ability to **configure noise cancellation options** at the **bot level**, based on:
  * Performance requirements
  * Use-case preferences

### Why Third-Party Tool in RTC? <a href="#why-krisp-in-rtc" id="why-krisp-in-rtc"></a>

#### Advanced Features for Optimal Audio Processing

* Superior Noise Cancellation: Utilizes neural network processing to effectively eliminate background noise such as traffic, typing, and barking dogs.
* Voice Preservation: Ensures natural speech quality by maintaining clarity without introducing artifacts.
* Real-Time Processing: Engineered for low-latency telephony with 20ms frame optimization.
* VAD-Integration: Incorporates built-in Voice Activity Detection to enhance OpenAI speech recognition accuracy.
* Adaptive Thresholds: Automatically adjusts VAD sensitivity to noise level variations, ensuring consistent performance.

#### **Key Capabilities:** Real-Time Audio Processing Features

* Noise Cancellation: Effectively apply noise cancellation to user audio streams for improved clarity.
* SDK/API Integration: Seamlessly integrate third-party tools within the iXHC Real-Time Channel.
* Low-Latency Processing: Maintain natural conversation flow with minimal delay.
* Bot-Level Configuration: Easily configurable settings tailored to individual bots.
* Azure OpenAI Compatibility: Ensure full compatibility with Azure OpenAI's real-time streaming architecture.
* Secure Processing: Conduct secure, on-device or in-stream processing without storing raw audio or sharing with third parties.

### **How It Works**

* Audiorouting: iX Hello routes microphone input through the Third-Party Tool.
* Noise Suppression: Tool's AI filters out non-human sounds, by enabling the Noise Reduction toggle button
* Real-Time Output: Clean audio is transmitted instantly to the other participant.
