vocal tract tube noise model


This is an experiment to generate plosive voice /ga/ /ka/ sound by pseudo blast impulse, noise source instead of turbulent sound, and two tubes model with loss.

github repository

usage

Generate following vowel sound, using two tubes model with loss


python3 main2varloss_1a.py

figure1

Generate preceding noise sound, using perlin noise


python3 PerlinNoise.py

figure2

Generate pseudo blast impulse and mix with the noise sound


python3 mix_impulse.py

figure3

Apply resonance effect to the mixed sound


python3 main2noiseresona_ku.py

figure4

Combine preceding mixed sound and following vowel sound


python3 make_gka.py

figure5

It will save gka_1a1_varloss0_0_noise0_i40_s600_resona_0.wav that sounds similar to voice /ga/ sound
and wii save gka_1a1_varloss0_01_noise0_i40_s600_resona_0.wav that becomes unvoiced sound.
