letalker.typing

typing Module

The typing module defines the custom type hints.

class letalker.typing.SimResultsDict

Dict of letalker simulation per-element outputs

letalker.typing.TwoLetterVowelLiteral

Possible values are:

'aa', 'ii', 'uu', 'ae', 'ih', 'eh', 'ah', 'aw', 'uh', 'oo', 'trach'

These codes specify vocal tract areas. These can be used for the areas argument of the letalker.LeTalkerVocalTract constructor. Also, they are the keys of the letalker.constants.vocaltract_areas dict.

The two-letter vowel codes specify the built-in (supraglottal) vocal tract configurations to produce the specified vowel (44-segment models) while the last option, "trach", is a 32-segment trachea (subglottal) vocal tract model.

letalker.typing.StepTypeLiteral

This literal specifies the transition types supported by letalker.StepGenerator and other function generators with transition_type argument. There are 9 options:

Option	Transition Description
"step"	Instantaneous
"linear"	Linear
"raised_cos"	Raised cosine
"exp_decay"	Exponential decay
"exp_decay_rev"	Reverse exponential decay
"logistic"	Logistic function
"atan"	Arctangent function
"tanh"	Hyperbolic tangent
"erf"	Err Function

letalker.typing.WhiteNoiseDistributionLiteral

This literal specifies the supported probability distributions for generating noise samples via WhiteNoiseGenerator or ColoredNoiseGenerator. Possible values are:

Option	Distribution Description
"gaussian"	Gaussian (normal) distribution
"two_point"	Symmetrical two-point distribution
"uniform"	Symmetrical uniform distribution
