How Text To Speech Can Help The Railway Industry

Railway systems, such as the metro, long-distance train, or suburban networks, are becoming increasingly important when it comes to solving transport problems derived from the increase in population in countries, cities or municipalities, since they offer a solution of Adequate mobility for residents. These infrastructures are used daily by a large number of people; therefore, it is necessary to have an effective tool to be able to inform as well as to mobilize people in case of emergency. For this, public address and voice alarm systems are used that allow rapid and controlled communication to large groups of people. Keep reading How Text To Speech Can Help The Railway Industry; we will tell you about Woord, a digital solution to improve loudspeaker communications.

Some technical aspects

Remember that this type of infrastructure always requires the next things:

A public address system that allows sound reinforcement by zones
An IP public address system
A properly certified public address and voice alarm system.
A public address and evacuation system that facilitates adequate intelligibility levels.
Carrying out acoustic studies and simulations.
Integration with SCADA and SIV.
A public address system that allows automatic volume control.

For all these reasons, when entrusting public address and voice alarm projects in railway networks, seek the help of professionals with experience in this type of project.

On the other hand, it is important to have quality software. In our case, we recommend Wwewewe, since it provides natural voices in all languages, with a wide variety of accents and dialects, as well as gender. In addition, this technology offers the possibility of editing in detail pauses, emphasis, tones and even breathing.

Transportation voices

They are everywhere: in every corner of every station, in the main hall, inside the carriages. The voices of the different subways of the world have become part of the mythology of every urban transport system. Mechanical, sweet, serious, prominent, whatever their character, they define its metro system, maximum exponents of the neutrality and routine familiarity of the trains that come and go at all hours.

In the past, these voices were from real people, but as time goes by, the story changes. Currently, more and more members of the Railway Industry are opting for intelligent software to develop the voices that accompany us daily.

Creating synthetic voices

To verbally interact with a human interlocutor, artificial intelligence generates realistic synthetic voices. For this, it is necessary to create the voice clone of a professional announcer using powerful neural networks (DNN).

How does it work? Technicians feed audio recordings of an actor into software (a specialized type of DNN), which will identify the human voice to create a synthetic voice model. This model will be able to imitate the pitch, pronunciation, accent and rhythm of the human voice in completely invented scripts.

This voice AI technology is what we call deep learning.

The evolution of speech synthesis AI, less data needed and more accurate results

The creation of synthetic voices through Artificial Intelligence (AI) has experienced an exponential improvement in recent years, since less data is needed to obtain increasingly realistic voices.

Currently, the development of synthetic voices has undergone a great change and it can be seen how the creation process has varied. To clone a human voice, until recently, thousands of real voice data (samples of that voice) had to be provided to obtain a similar synthetic one. Therefore, this leads to consuming a lot of time for research and recording of those samples. Today, thanks to AI technology, that sample collection and recording time has been reduced. The simplification of the process brings synthetic voices closer to all users and companies.


Woord is a without-charge online text reader with a variety of useful features. It contains more than 50 languages, including a variety of dialects. Furthermore, this API allows one to choose between masculine, feminine, or non-binary voices.

All of these features are available without charge, allowing you to test the service before purchasing the premium version. Premium voices, a Chrome plugin, an SSML editor, an MP3 download, and up to 20,000 characters each month are all included in the without-charge edition. With this program, you may also adjust the voice’s speed and format.

Nonetheless, we recommend that for commercial use you buy a premium subscription to this natural voices API; they are economic and ready for commercial use. Also, with the premium versions of Woord, you 100% own intellectual property for all files.
