Tuben: Re-introducing a computer program by Liljencrants and Fant (1975) for simulating vocal tract area transfer functions
Axel G. Ekström, Jonas Beskow · 2023
Liljencrants and Fant (1975) designed a computer program for modelling vocal tract area transfer functions as sequences of rounded tubes. Here, we present Tuben, an updated version of the program, written in the Python programming language. We present a use case of the program, replicating vocal tract shapes for point vowels /a/, /i/, and /u/. The program has been made publicly available and presents researchers and students in speech-centric sciences with easily accessible vocal tract modelling and vowel synthesis.
