![]() Formant synthesis: using formants, a term to describe what our vocal tracts produce characteristically, one can replicate sounds.These units are then used to generate user-defined patterns of sound. Concatenation synthesis: this technique takes the approach of concatenating or linking together short samples of recorded sound in a chain called units.Two basic techniques are commonly used in the application of text-to-speech synthesis. The different techniques used for text-to-speech The system would act as the foundational technology that many organizations base their speech synthesis systems on. First premiering in 1976, the Kurzweil Reading Machines for the Blind was a reading aid using an optical scanner, which was quite adequate for the visually impaired.Īnd just before the end of the decade, specialists at MIT developed a more sophisticated text-to-speech system. Throughout the 70s and 80s, advancements in the technology continued. Noriko Umeda and his colleagues made a system that could produce intelligible speech outputs, but it was far from authentic-sounding voices, which future technology advancements would help achieve. The complete text-to-speech system, developed for English, was built in 1968 in Japan at the Electrotechnical Laboratory. Advancements in speech synthesizers in the 1920s paved the way for the development of the first text-to-speech system. The idea of a speech synthesis machine dates back to the 1700s, with development continuing into the 19 th and 20 th centuries. What is the best TTS voice, and how can you create one?Ī quick history on text-to-speech synthesis.Breaking down the process of AI-powered synthetic speech.The different techniques used for text-to-speech.A quick history on text-to-speech synthesis. ![]() To understand the differences, we’ll cover in this blog: Briefly touched on in our previous blog on voice cloning, text-to-speech is an approach that has historically been more limited than what voice cloning technology can do today. As the third installment in our Deepfake Voice series, we will focus on text-to-speech synthesis and how artificial intelligence (AI) has evolved to make accurate, realistic voice outputs.
