Acapela TTS Voices - Text-to-speech & voice purchase

Acapela TTS enables you to purchase and install our premium voices on your Android device, allowing integration with the system or any applications that support TTS (such as accessibility apps, various GPS apps, translator apps, ebook readers, news readers, etc.).

The application is available for free, giving you the opportunity to explore all of our voices online. However, in order to utilize any voice offline with TTS-compatible applications, you must buy at least one voice from within the app (In-app Billing - EUR 3.99 per voice and EUR 11.99 for kids' premium voices).

NEWS

Acapela Group is expanding its selection of synthetic voices for young German-speaking users with the addition of four new child voice-AI characters: Finn, Leonie, Mathilda, and Nele. Meet them!

Inviting young users to choose from a wide range of AI-based voices

These new AI speech synthesis voices join existing German children’s voices, Jonas and Lea, bringing the total to six. Designed to provide natural, relatable tones for children with speech or communication challenges, the new text to speech voices add cheerfulness, spontaneity, and a range of personas.

“At Acapela, we are deeply committed to providing young users with diverse, engaging options to empower them to communicate confidently and connect meaningfully with their peers.” comments Remy Cadic, CEO of Acapela Group.

Empowering Communication and Self-Expression

Acapela first introduced German text to speech voices for children in 2013 to enable young users to express themselves with age-appropriate tones instead of generic or adult-like ones. Over the past decade, Acapela has expanded its portfolio across multiple languages, now helping thousands of young users daily with 50 voices available in ten languages.

These new AI-based German voices mark another step in Acapela’s commitment to empowering children to communicate, play, grow, and learn through AAC (Augmentative and Alternative Communication) applications.

These voices were born out of a market survey involving AAC stakeholders, professionals, and, most importantly, users.

Advancing Neural Voice Technology

The new German child voices are powered by Acapela’s neural voice technology  (AI), delivering lifelike audio, improved real-time interactions, and an enriched user experience, all supported by Acapela’s extensive vocal library developed over the past two decades.

FAQS

WHAT IS A DIGITAL VOICE?

It’s the artificial production of human speech. The computer system used to achieve this is called a speech engine. Acapela Text To Speech (TTS/Speech synthesis) transforms any text into speech in real time. It literally reads out loud any written information with a smooth and natural sounding voice. The automatic intonation reflects the meaning of the text, with respect to pauses, breath groups, punctuation and context. The most important qualities of a speech synthesis system are naturalness and intelligibility + expressiveness.

WHAT IS DNN?

DNN (Deep Neural Networks)

A deep neural network (DNN) is an artificial neural network (ANN) with multiple hidden layers between the input and output layers. DNNs can model complex non-linear relationships. We use them in Text-to-Speech to learn the relationship between a set of input texts and their acoustic realizations by different speakers.

Neural networks are a set of algorithms, modelled loosely after the human brain, that are designed to recognize patterns. They interpret sensory data through a kind of machine perception, labelling or clustering raw input. The patterns they recognize are numerical, contained in vectors, into which all real-world data, be it images, sound, text or time series, must be translated.

Neural Networks have revolutionized artificial vision and automatic speech recognition. This machine learning revolution is holding its promises as it enters the Text to Speech arena. Acapela Group is actively working on Deep Neural Networks. With Acapela DNN, we create a voice using a limited amount of existing or new speech recordings.

WHERE ACAPELA'S VOICES CAN BE USED?

Basically, anywhere where voice makes sense. Historically, voice solutions were initially developed to allow people suffering from visual impairments to access written information. They are now a standard component in applications and services and the new interface revolution with the voice-first. We provide companies with digital voice solutions that are extensively used by everyone, changing the way we access content and information in our daily lives. Ease life for visually and speech impaired users: screen and web page readers, reading machines, communicators and navigators.
