Calls go through noise suppression tools before reaching a conversational AI chatbot

This blog post is Part Two of a four-part series where we’ll discuss conversational AI and the developments making waves in the space.

In the rapidly evolving landscape of conversational AI, one challenge consistently stands in the way of seamless user interactions: background noise. As developers, we strive to create chatbots that can understand and respond accurately, irrespective of the environment. But how do we ensure clarity in a cacophony?

Enter noise suppression technology, a powerful tool that filters out irrelevant noise, leaving only the clear, crisp commands our chatbots need to function effectively. This technology has the potential to dramatically improve the performance of our chatbots, making them more reliable and user-friendly.

Imagine a chatbot that can accurately interpret commands in a bustling coffee shop, a busy office, or even a windy park. With noise suppression technology, this level of performance is within our grasp. It's time to elevate our chatbots from being merely functional to being impressively robust in any environment.

In this post, we'll explore how noise suppression works, the role of deep learning, and the latest advancements in real-time and cloud-based noise suppression. Keep reading to learn how to enhance your conversational AI chatbots and stay ahead in this rapidly evolving field.

What is noise suppression?

In real-world scenarios, conversations with AI often take place in environments with a lot of background noise, such as busy streets, crowded rooms, or even just a home with other people talking or music playing in the background. This noise can interfere with the AI's ability to accurately interpret the user's commands or questions.

Noise suppression technology works to filter out these background noises, leaving only the relevant speech components. This enhances the AI's ability to understand and respond to user commands accurately, even in noisy environments.

Deep learning has changed the game for noise suppression

The technology behind noise suppression has evolved significantly over the years. While traditional methods relied on Digital Signal Processing (DSP) techniques, modern noise suppression often leverages advanced deep learning algorithms.

Traditional noise suppression techniques based on DSP have limitations in handling the wide variety of noises present in real-world environments. But deep learning algorithms can effectively differentiate between human speech and background noise, enabling more precise noise suppression.

This differentiation is achieved by training a deep neural network (DNN).) on a large dataset of synthetic noisy speech, teaching it to produce a ratio mask for every audio frequency that retains the human voice while filtering out the noise.

The intersection of noise suppression and conversational AI

Conversational AI chatbots are designed to mimic human-like conversations, understanding and responding to verbal or written commands. However, in real-world scenarios, these interactions often take place in noisy environments. All that background noise can interfere with a chatbot's ability to accurately interpret a user's commands. That’s where noise suppression comes into play.

Noise suppression filters out that background noise from an audio signal, leaving only the relevant speech components. This filtering is crucial for conversational AI chatbots, as it enhances their ability to accurately understand and respond to user commands, regardless of the noise level in a caller’s surroundings.

Real-time noise suppression enhances conversational AI performance

For conversational AI chatbots, it's not just about suppressing noise but doing so in real time. Any latency in the conversation can lead to a disjointed and frustrating user experience. Deep learning algorithms, despite their complexity, have shown promise in achieving real-time noise suppression.

The key to real-time noise suppression lies in optimizing the DNN architecture, the compute platform capabilities, and the audio sampling rate. With the right balance, it's possible to achieve real-time noise suppression with DNNs, ensuring smooth and clear conversations with AI chatbots.

Leverage Telnyx for next-gen noise suppression

Noise suppression technology plays a pivotal role in enhancing the performance of conversational AI chatbots. With advancements in deep learning, we can expect to see more sophisticated and scalable noise suppression solutions that will further improve the quality of interactions with AI chatbots.

But all these advancements are of little use to conversational AI developers without a solid platform from which you can access and implement them. Luckily, Telnyx has incorporated next-gen noise suppression into its Programmable Voice tools, so that users can enable noise suppression in every call.

With intelligent real-time noise suppression on the Telnyx SIP network, your calls will reach your AI tools without confusing background noise. When your conversational AI can understand what callers are saying with more clarity, it can generate more realistic responses with fewer uncanny delays.
