What characteristic did Parametric Speech Synthesis use to generate speech output?
Answer
Mathematical models describing speech characteristics such as pitch, tone, and duration
Parametric Speech Synthesis represented a significant advancement beyond simple concatenation. Instead of relying strictly on recorded pieces, this approach utilized mathematical models. These models were designed to describe and parameterize the crucial characteristics of speech—specifically elements like pitch contour, tone quality, and the duration of sounds. By manipulating these parameters, computers gained flexibility to generate speech, moving closer to functional output, although it still struggled significantly in capturing the subtle, idiosyncratic textures that truly distinguish one person's voice from another.
