Kõnesünteesi

Kõnesünteesi, also known as speech synthesis, is the artificial production of human speech. It is a computer-generated process that converts written text into spoken audio. The goal of kõnesünteesi is to create speech that is natural-sounding and understandable.

There are two main approaches to kõnesünteesi: concatenative and parametric. Concatenative synthesis involves stitching together pre-recorded units of speech, such as phonemes, diphones, or words. This method can produce very natural-sounding speech, but it requires a large database of recordings and can be computationally intensive. Parametric synthesis, on the other hand, generates speech based on a set of acoustic parameters that define the characteristics of the speech signal, such as pitch, duration, and timbre. This approach is more flexible and requires less storage space, but the speech quality may be less natural.

Kõnesünteesi technology has a wide range of applications. It is used in assistive technologies for individuals with visual or speech impairments, providing them with access to written information through spoken output. It is also employed in navigation systems, virtual assistants, audiobooks, and interactive voice response (IVR) systems. Advancements in artificial intelligence and machine learning have significantly improved the quality and naturalness of synthesized speech in recent years, making it increasingly indistinguishable from human speech. Continued research aims to further enhance prosody, emotion, and individual voice characteristics in synthesized speech.
