📌 Echo Suppression Summary
Echo suppression is a technique used in audio and telecommunication systems to reduce or eliminate echoes that can occur during a conversation. Echoes happen when a speaker’s voice is picked up by their own microphone after bouncing back from the other person’s device or the environment. By detecting and minimising these unwanted sounds, echo suppression improves the clarity and quality of calls or audio recordings. This is especially important in hands-free or speakerphone situations, where sound can easily loop back into the microphone.
🙋🏻♂️ Explain Echo Suppression Simply
Imagine talking in a big empty room and hearing your own voice come back to you a moment later, making it hard to concentrate. Echo suppression is like having an invisible helper who quickly turns down the echo so you can hear the other person without distractions. It makes conversations smoother, especially when using devices like speakerphones or video calls.
📅 How Can it be used?
Echo suppression can be integrated into a video conferencing app to ensure clear, echo-free audio for all participants.
🗺️ Real World Examples
In car hands-free calling systems, echo suppression is used to prevent the driver’s voice from being echoed back through the car speakers and microphone, ensuring that both the driver and the person on the other end of the call hear each other clearly.
During online gaming voice chats, echo suppression helps avoid repeated sounds when multiple players are speaking and using speakers instead of headphones, making group conversations clearer and more enjoyable.
✅ FAQ
Why do echoes happen during phone calls or video chats?
Echoes during calls often occur when your voice travels through the speaker on the other end and is picked up again by their microphone. This can create a loop where you hear your own words repeated, which can be distracting and make conversations harder to follow. Echo suppression helps stop this from happening, so both people can enjoy clearer calls.
How does echo suppression help in hands-free or speakerphone calls?
When using hands-free or speakerphone modes, the microphone and speaker are close together, making it easy for sound to bounce back. Echo suppression works by detecting these returning sounds and reducing or removing them, so your voice comes through cleanly without the annoying repeat.
Is echo suppression the same as noise cancellation?
Echo suppression and noise cancellation are different. Echo suppression targets repeated sounds that come from your own voice bouncing back, while noise cancellation focuses on removing background sounds like traffic or chatter. Both make calls clearer but deal with different problems.

Data Audit Framework
A Data Audit Framework is a structured set of guidelines and processes used to review and assess an organisation's data assets. It helps identify what data exists, where it is stored, how it is used, and whether it meets quality and compliance standards. The framework is designed to ensure that data is accurate, secure, and aligned with business and regulatory requirements.
Stream Processing Pipelines
Stream processing pipelines are systems that handle and process data as it arrives, rather than waiting for all the data to be collected first. They allow information to flow through a series of steps, each transforming or analysing the data in real time. This approach is useful when quick reactions to new information are needed, such as monitoring activity or detecting problems as they happen.
Model Compression
Model compression is the process of making machine learning models smaller and faster without losing too much accuracy. This is done by reducing the number of parameters or simplifying the model's structure. The goal is to make models easier to use on devices with limited memory or processing power, such as smartphones or embedded systems.
Insider Threat
An insider threat refers to a risk to an organisation that comes from people within the company, such as employees, contractors or business partners. These individuals have inside information or access to systems and may misuse it, either intentionally or accidentally, causing harm to the organisation. Insider threats can involve theft of data, sabotage, fraud or leaking confidential information.
Anomaly Detection Pipelines
Anomaly detection pipelines are automated processes that identify unusual patterns or behaviours in data. They work by collecting data, cleaning it, applying algorithms to find outliers, and then flagging anything unexpected. These pipelines help organisations quickly spot issues or risks that might not be visible through regular monitoring.
