What is articulatory speech synthesis?
Articulatory synthesis is the production of speech sounds using a model of the vocal tract, which directly or indirectly simulates the movements of the speech articulators. It provides a means for gaining an understanding of speech production and for studying phonetics.
How does a speech synthesizer work?
A speech synthesizer is a computerized voice that turns a written text into a speech. It is an output where a computer reads out the word loud in a simulated voice; it is often called text-to-speech. It is not only to have machines talk simply but also to make a sound like humans of different ages and gender.
What is meant by speech synthesis and speech recognition feature?
Speech synthesis is artificial simulation of human speech with by a computer or other device. The counterpart of the voice recognition, speech synthesis is mostly used for translating text information into audio information and in applications such as voice-enabled services and mobile applications.
How does formant synthesis work?
By manipulating the shape and size of that resonant space (i.e., by changing the shape of the mouth and throat), we change the location of the formants in our voice. We recognize different vowel sounds mainly by their formant placement.
What type of audio format supports speech synthesis?
Formats supported: Users won’t find any difficulty in playing the downloaded audio as the same is supported in multiple formats like wav, mp3, ogg, wma, aiff, alaw, ulaw, vox and mp4.

What is the difference between speech synthesis and speech recognition?
Speech synthesis is being used in programs where oral communication is the only means by which information can be received, while speech recognition is facilitating commu- nication between humans and computers, whereby the acoustic voice signals changes in the sequence of words making up a written text.
How are AI voices made?
Synthetic voice is produced in three stages: Text to words, words to phonemes and phonemes to sound. It can use recordings of humans saying the phonemes (concatenative), it can reference basic sound frequencies to generate the sounds itself (formant) or it can mimic the mechanisms of the human voice (articulatory).
When was the first speech synthesis system invented?
The first computer-based speech-synthesis systems originated in the late 1950s. Noriko Umeda et al. developed the first general English text-to-speech system in 1968, at the Electrotechnical Laboratory in Japan.
How does formant synthesis use human speech samples?
Formant synthesis does not use human speech samples at runtime. Instead, the synthesized speech output is created using additive synthesis and an acoustic model (physical modelling synthesis).
How is concatenative synthesis used in speech synthesis?
Concatenative synthesis is based on the concatenation (or stringing together) of segments of recorded speech. Generally, concatenative synthesis produces the most natural-sounding synthesized speech.
How is intelligibility and naturalness related in speech synthesis?
Naturalness describes how closely the output sounds like human speech, while intelligibility is the ease with which the output is understood. The ideal speech synthesizer is both natural and intelligible. Speech synthesis systems usually try to maximize both characteristics.
