The Evolution of Text–to-Speech:

‍From Siri, to Alexa, Text-to-speech has revolutionized user-experience, and continues evolving year on year. According to Data research and consulting company ‘Brouton Lab’, recent estimations value the TTS industry at $3 billion by the end 2022, with an expectation to grow even further in the coming years. 

‍Fortunately, with this time, comes evolution. And over the last few years, the quality and naturalism of TTS voices has also improved exponentially. Machine-learning algorithms are constantly working to make their voices sound more human-like than ever before, in tone, emotion, and various other vocal nuances. The research and development in neural voices has brought on many of these changes. 

‍This ever-growing market has naturally created huge opportunities for TTS voice providers to break through big-time. However with so many out there, it can be hard to define which providers are worth using for your business. That’s why we have put together this list of the Top 8 best TTS voice providers, so that you don’t have to. 

So, without further ado, let’s take a look:

1. Microsoft Azure

‍At the forefront of TTS voices, Microsoft Azure offer AI voices in a plethora of languages, as well as supporting various styles such as ‘confident’ sounding voices. They also have voices fit for specific purposes, such as a ‘chatbot’ voice, amongst others. In Aflorithmic’s voice library, we have over 300 Microsoft Azure for you to choose from and integrate into your business’ audio content.‍

Their stable and reliable voices are available in many of the most used European languages such as Spanish, French, German and English. Their English voices are also available in localized accents in Aflorithmic’s voice library. For example, British English, American English or American English accents.
