How Does TTS Excellence Enhance Airport Announcements?

For years, updating airport announcements meant waiting on voice talent recordings, and the alternatives were not much better. Airport CX was built to change that. The TTS Editor combines Microsoft Azure text-to-speech with the expertise of a dedicated voice team, so airports can deliver natural-sounding, multilingual announcements that update in real time alongside live flight data. This article explains how it works.

Over the years, airports have grappled with lengthy delays in delivering announcement updates due to the reliance on voice talents for recording of the announcements. This traditional approach has become increasingly problematic in today's fast-paced environment. In the past, the only alternatives were unprofessional recordings by airport staff or robotic-sounding text-to-speech (TTS) announcements.

However, text-to-speech technology has come a long way, with voices that now sound genuinely natural. At Simpleway, we get that real authenticity needs a human touch. This is the very reason that advanced TTS Editor is part of our Airport CX.

TTS Editor uses Microsoft Azure Text to Speech and connects directly to Airport CX flight data, where our voice experts show their incredible skills, and you can join them too. This tool allows you to make powerful changes keeping announcements accurate, dynamic, and responsive to real-time demands. Thanks to this, we now offer our customers a service combining both: faster delivery and human-like quality content.

How do we make professional sounding text-to-speech flight announcements?

We've assembled a reliable and proficient Voice Team, where each member is well-versed in a minimum of three languages and armed with strong linguistic and technical expertise. They function as the bridge between the technology and the nuances of human expression, so announcements land clearly for anyone, anywhere. Our team can train you and your colleagues to create content yourselves or handle it on your behalf.

When creating the content, it is important to pay close attention to details like natural pauses between words and phrasing, to make the artificial voice sound natural and human-like. Using specialized intonation tools of TTS editor is necessary for better adjustments and in languages other than English, we emphasize phoneme features for correct pronunciation of difficult terms like destination and airline names. This commitment to accuracy improves the clarity of information in our TTS announcements, for a clear, consistent experience across a diverse audience.

Pronunciation

With the pronunciation feature, we can adjust how each word sounds. This is very helpful for dealing with difficult words and making sure that we say the names of places, airlines, and other specific words correctly. Our Voice Team monitors the aviation world and learns how to pronounce all the airline names in different languages. That way, our announcements can communicate the message in a clear and professional way without any embarrassing mistakes.

Rate

Changing the speed of voice is a feature that gives us a flexible way to control the timing of our announcements. Reducing the speed can improve understanding, especially for complicated messages like information about the flight. On the other hand, speeding up the voice can create a feeling of urgency or excitement when needed, grabbing the audience's attention during important announcements such as boarding calls or safety instructions.

Intonation

Creating natural intonation is essential for making our announcements sound fluent and expressive like humans. The intonation feature allows our experts to adjust the melodic patterns of speech, matching the rhythms and tones of natural dialogue. This way we can guarantee that the text-to-speech announcements are of the best quality and very similar to real human voices. Voices that sound robotic with flat intonation are outdated!

Volume

Adjusting the volume levels makes sure that our announcements are consistent and loud enough in different situations. Increasing the volume of important information makes it stand out from background noise, so passengers hear what matters.

SSML Text

SSML text is a function that we created at Simpleway to let us insert unseen punctuation marks and other signs, like commas or dashes to the announcement. It imitates the rhythm of natural speech - adding pauses and distinguishing sentence structures, while the text to be viewed remains unchanged in your system or on flight displays as visual paging.

How does the process of creating a new announcement look like?

You can create good quality announcements with any appropriate text to speech tool. Our TTS Editor has some unique features that make it stand out, such as automation and customization. You don't have to type the whole announcement as text. You can define different options for what you want your announcement to include, and you can decide right before playing depending on the situation. Or you can leave some parts of the announcement empty, and fill them in just before playing, such as a person's name, car registration number, or anything else. But the most powerful thing is the connection with your data. You can use "placeholders" for your flight numbers, destinations, resources such as gates, or any other possible variable you can imagine.

Let's examine them more closely:

Options

Options allow you to set fixed values to select before making an announcement. They can serve various purposes. For instance, consider the selection of boarding rows with adjustable numbers based on the passengers currently boarding the aircraft. Alternatively, options can be a predefined set of words, as demonstrated in this example. In this case, the operator must choose the reason for the flight delay before playing the announcement.

Custom variables

A blank space can be added to a new announcement, which will be filled in right before the announcement is played. For instance, this can be useful for announcing the names of the last passengers who need to board. With the latest text-to-speech technology that can switch quickly among different languages, names from various countries can be spoken correctly.

Variable parts

Our system uses the most recent flight data, which is automatically included in the announcements. When you make the announcement, you just specify what kind of information you need from the flight data, and it will be added automatically when you press play! Here is an example of the announcement, with the variable parts shown by green bubbles and the result.
