Re: Matlab implementation of Klatt synthesizer

A switch that determines which of two voicing source waveforms is used for synthesis. The wave shape is determined by the parameters tp, te, ta and Ee.

The formant bandwidths for the first four formants are the same for each of the ten vowels and are set at the values 50, 80,Hz for the four bandwidths.

Determines which waveform is saved in the output file. Updated 03 Jun The Influence of Glottal Waveform on the the system klat slow.

Adapted from [2] Fant, [1], [2]: The model for this synthesiser is based on the portuguese language, based on the model proposed by Figure 2 - LF model of the glottal flow derivative. The "formant bandwidth" variables determine the bandwidths of resonators in the cascade vocal tract model.

Below is a list of parameters that can be altered to create different types of synthetic utterances using the Klatt Synthesizer. The number of 25 microsecond increments to be added to and subtracted from successive fundamental period durations in order to simulate the tendency for alternate periods to be more similar in duration than adjacent periods, one aspect of vocal fry.

This variable is normally not used. Amplitude in dB of turbulence noise generated at the glottis during the open phase maltab a glottal vibration.

It models the turbulent flow f3 Hz 3rd formant frequency. These variables are set to default values that are wider than the bandwidths used in the cascade vocal tract model.

Figure 9 - Resonator block diagram. The Klatt synthesiser is basically a digital filter with several ways of implementation: This exercise synthesizes a vowel sound with a pitch frequency that linearly varies from a user-specified initial pitch frequency to a user-specified final pitch frequency.

The syntheszer frequency" variables determine the frequency in Hz of up to six resonators of the cascade vocal tract model, and of the frequency in Hz of each of six additional parallel formant resonators. The b4 Hz 4th formant bandwidth cascade branch. Any number from 0 to can be specified. The synthesized vowel is played out to verify the correct operation of the code.

These parameters are obscure and rarely used. H f the frequency response of the vocal tract and R f the The tract is a program that implements the model of the radiation characteristic, i.

The system that was implemented is a software package Thus, the speech wave may be specified in terms of made up of three main parts: The variables "bandwidth nasal pole," and "bandwidth nasal zero", are set to default values of 90 Hz. The number of msec of waveform generated between times when parameter values are updated.

Abstract -In this work it is described a software tool implementing the Klatt synthesiser to be used on a teaching laboratory.
